Multi page PDF from AppScript - How to insert page breaks? [duplicate] - pdf

I would like to programmatically set page breaks in my Google Spreadsheet before exporting to PDF, using Apps Script
It should be possible as you can manually set the page breaks when you print the Spreadsheet (https://support.google.com/docs/answer/7663148?hl=en)
I found that it's possible in Google Docs (https://developers.google.com/apps-script/reference/document/page-break) but they don't mention it on the sheet.
Is there a way to do it, even if it's a "hack"?

Talking about "hacks", you may try to capture HTTP request sent from the Spreadsheet to Google when you are trying to save a sheet as PDF by going to the developer tools - Network.
From this link you can get formatting parameter pc, which in my case looks like this:
[null,null,null,null,null,null,null,null,null,0,
[["1990607563"]],
10000000,null,null,null,null,null,null,null,null,null,null,null,null,null,null,
43866.56179325232,
null,null,
[0,null,1,0,0,0,1,1,1,1,2,1,null,null,2,1],
["A4",0,6,1,[0.75,0.75,0.7,0.7]],
null,0,
[["1990607563",[[45,92],[139,139]],[[0,15]]]],0]
where:
[["1990607563",[[45,92],[139,139]],[[0,15]]]],0] // page breaks parameters
Note though that I used custom page breaks and landscape orientation, which are reflected in the response above.
Putting it all together, the following code does the trick:
function exportPDFtoGDrive (ssID, filename, source){
var source = "1990607563"
var dt = new Date();
var d = encodeDate(dt.getFullYear(),dt.getMonth(),dt.getDate(),dt.getHours(),dt.getMinutes(),dt.getSeconds());
var pc = [null,null,null,null,null,null,null,null,null,0,
[[source]],
10000000,null,null,null,null,null,null,null,null,null,null,null,null,null,null,
d,
null,null,
[0,null,1,0,0,0,1,1,1,1,2,1,null,null,2,1],
["A4",0,6,1,[0.75,0.75,0.7,0.7]],
null,0,
[[source,[[45,92],[139,139]],[[0,15]]]],0];
var folder = DriveApp.getFoldersByName("FolderNameGoesHere").next();
var options = {
'method': 'post',
'payload': "a=true&pc="+JSON.stringify(pc)+"&gf=[]",
'headers': {Authorization: "Bearer " + ScriptApp.getOAuthToken()},
'muteHttpExceptions': true
};
const esid = (Math.round(Math.random()*10000000));
const theBlob =
UrlFetchApp.fetch("https://docs.google.com/spreadsheets/d/"+ssID+"/pdf?id="+ssID+"&esid="+esid, options).getBlob();
folder.createFile(theBlob).setName(filename+".pdf");
}
function myExportPDFtoGDrive(){
var ss = SpreadsheetApp.openById('yourSpreadSheetID');
var sheet = ss.getSheetByName("NameGoesHere");
var filename = ss.getName()+" ["+sheet.getName()+"]";
exportPDFtoGDrive (ss.getId(),filename);
}
A more detailed explanation of the hack is available here
Export Google Sheets to PDF though in Russian only.

I use a work around. I adjust the page size by altering the row height to fit the paper size I want (A4).
When exporting to pdf google changes sizes to fit the width. I add up the size of the columns and then set the row heights accordingly. Numbers were chosen by trial and error.
var width = 0;
for(var z = 0; z < s4.getLastColumn(); z++){
width += s4.getColumnWidth(z+1);
}
var a4PageHeightPixels = 1050 * width / 800;
Because I wanted the rows all the same height I set the row height dividing my page height by the number of rows. Having ensured the last row was blank, I adjusted the last row to take up the rounding error.
rowHeight= Math.floor(a4PageHeightPixels/(numDataRows ));
lastRowHeight = a4PageHeightPixels - (numDataRows -1) * rowHeight;
s4.setRowHeights(pageFirstRow,numDataRows-1,rowHeight);
s4.setRowHeight(pageFirstRow+numDataRows-1,lastRowHeight);
(s4 is the sheet I am using)However, I would expect most people would simply want to insert a blank line at the bottom of each page and adjust its size to fit the pdf paper size.

Google Docs PDF Export Adds Extra Blank Pages at the End

I use google spreadsheet to create invoices and send them by email in PDF format, it's been working great, my spreadsheets are yearly base, so every new year I create another one, all my spreadsheet from 2021 are still working fine, but all the new ones I've created for 2022 when I try to print or export PDFs, extra blank pages are beeing added to the end of the document. The number of blank pages are dependent on the number of blank lines on the sheet, but I didn't have this problem before, before even when the sheet has 1000 lines, if the invoice has only 1 page the PDF/Print will only generate 1 page, now if the sheet has 1000 lines it generates 19 blank pages.
Anyone with same problem or a solution?
Link for example: Spreadsheet link
Try to print or download the page and you will see the blank pages generated.
function savePDF() {
const ssh = SpreadsheetApp.getActiveSpreadsheet();
const invoice = ssh.getSheetByName('invoice');
const request = {
"method": "GET",
"headers":{"Authorization": "Bearer
"+ScriptApp.getOAuthToken()},
}
const key = ssh.getId();
const bogus = DriveApp.getRootFolder();
const fetch='https://docs.google.com/spreadsheets/d/'
+ key
+'/export?format=pdf&gid='
+ invoice.getSheetId()
+
'&size=letter&portrait=true
&printtitle=false
&pagenum=CENTER
&sheetnames=false
&gridlines=false
&top_margin=0.25
&bottom_margin=0.50&left_margin=0.25
&right_margin=0.25';
const name = "invoice.pdf";
let pdf = UrlFetchApp.fetch(fetch, request);
pdf = pdf.getBlob().setName(name);
const fold = "Folder ID goes here";
const folder = DriveApp.getFolderById(fold);
const file = folder.createFile(pdf);
}
The issue is that it prints the whole sheet by default. So it includes all those blank lines, thus adding blank sheets.
What you can do as a workaround is to CTRL + A in the sheet, then export using Selected cells
Export:
As you can see, total number of pages is only 1.
Script:
I'm not sure why it just doesn't work right now, but there might have been some changes and defaulted to export the whole sheet. To bypass this issue, you will need to add the actual range to the link. See modifications below:
Modifications:
Get the A1 notation of the data range:
const ssh = SpreadsheetApp.getActiveSpreadsheet();
const invoice = ssh.getSheetByName('invoice');
// add this line
const range = invoice.getDataRange().getA1Notation();
Append the range into the link:
const fetch = 'https://docs.google.com/spreadsheets/d/' + key
+ '/export?format=pdf&gid=' + invoice.getSheetId()
+ '&size=letter'
+ '&portrait=true'
+ '&printtitle=false'
+ '&pagenum=CENTER'
+ '&sheetnames=false'
+ '&gridlines=false'
+ '&top_margin=0.25'
+ '&bottom_margin=0.50'
+ '&left_margin=0.25'
+ '&right_margin=0.25'
// add range to link
+ '&range=' + range;
Output:

pdf is created from google slide, but with the markers populated (via GAS)

The code below basically maps columns from a spreadsheet to a couple of markers I got on a google slide.
It generates copies of the google slide template, updates them with the row's data and I actually need it to be in pdf form to be emailed later.
The pdf files are created in the destination folder, with the right file names, but the markers within them are "empty". Later on, I will have to delete these google slide files, but the challenge here now is to have the pdf files correctly created.
Appreciate your time.
function mailMerge(templateID,ssID, sheetName, mapped, fileNameData, emailCol, rowLen = "auto"){
//Properties Services is Google Script Storage.
//This clears out the storage.
PropertiesService.getScriptProperties().deleteAllProperties();
const ss = SpreadsheetApp.getActiveSpreadsheet();
//const sheet = SpreadsheetApp.openById(ssID);
const sheet = ss.getSheetByName("Lista de Participantes");
//Get number of rows to process
rowLen = (rowLen = "auto") ? getRowLen() : rowLen;
const range = sheet.getRange(7,1,rowLen,sheet.getDataRange().getNumColumns());
const matrix = range.getValues();
const fileNameRows = getFileNameRows()
for(let i = 1; i < rowLen; i++){
if (matrix[i][1] == true && matrix[i][27] != "Sim") {
let row = matrix[i];
//Get the title for the file.
let fileName = buildFileName(row)
//Creates a copy of the template file and names it with the current row's details.
let newDoc = DriveApp.getFileById(templateID).makeCopy(fileName);
//Replaces all the text place markers ({{text}}) with current row information.
updateFileData(row, newDoc.getId());
//Save new File ID and email to Properties service.
PropertiesService.getScriptProperties()
.setProperty(newDoc.getId(),row[emailCol]);
// 5. Export the temporal Google Slides as a PDF file.
newDoc = DriveApp.getFileById(newDoc.getId());
DriveApp.getFolderById("folder ID").createFile(newDoc.getBlob());
}
};
Besides the code above, I go this script file within the same container/Spreadsheet, where I map the columns whose data I want to generate a google Slide for. each column of data I refer to as marker.
/*###################################################################
* Maps the relationship between the Google Sheet header and its location
* for each column along with it's corresponding Google Slide Doc template name.
*
* To update change the sheet, col and doc:

* col: << The column on the google sheet with the above header
* doc: << the corresonding name in double braces {{name}} in your Slide template
* }

const mappedDocToSheet = [

I believe your goal and situation as follows.
You add the values of Google Slides and create it to PDF data
newDoc is the Google Slides
In order to achieve your goal, please use saveAndClose. For your script, please modify as follows.
Modified script:
Please add the following script to your function of mailMerge as follows.
// 5. Export the temporal Google Slides as a PDF file.

Printing to pdf from Google Apps Script HtmlOutput

For years, I have been using Google Cloud Print to print labels in our laboratories on campus (to standardize) using a Google Apps Script custom HtmlService form.
Now that GCP is becoming depreciated, I am in on a search for a solution. I have found a few options but am struggling to get the file to convert to a pdf as would be needed with these other vendors.
Currently, when you submit a text/html blob to the GCP servers in GAS, the backend converts the blob to application/pdf (as evidenced by looking at the job details in the GCP panel on Chrome under 'content type').
That said, because these other cloud print services require pdf printing, I have tried for some time now to have GAS change the file to pdf format before sending to GCP and I always get a strange result. Below, I'll show some of the strategies that I have used and include pictures of one of our simple labels generated with the different functions.
The following is the base code for the ticket and payload that has worked for years with GCP
//BUILD PRINT JOB FOR NARROW TAPES
var ticket = {
version: "1.0",
print: {
color: {
type: "STANDARD_COLOR",
vendor_id: "Color"
},
duplex: {
type: "NO_DUPLEX"
},
copies: {copies: parseFloat(quantity)},
media_size: {
width_microns: 27940,
height_microns:40960
},
page_orientation: {
type: "LANDSCAPE"
},
margins: {
top_microns:0,
bottom_microns:0,
left_microns:0,
right_microns:0
},
page_range: {
interval:
[{start:1,
end:1}]
},
}
};
var payload = {
"printerid" : QL710,
"title" : "Blank Template Label",
"content" : HtmlService.createHtmlOutput(html).getBlob(),
"contentType": 'text/html',
"ticket" : JSON.stringify(ticket)
};
This generates the expected following printout:
When trying to convert to pdf using the following code:
The following is the code used to transform to pdf:
var blob = HtmlService.createTemplate(html).evaluate().getContent();
var newBlob = Utilities.newBlob(html, "text/html", "text.html");
var pdf = newBlob.getAs("application/pdf").setName('tempfile');
var file = DriveApp.getFolderById("FOLDER ID").createFile(pdf);
var payload = {
"printerid" : QL710,
"title" : "Blank Template Label",
"content" : pdf,//HtmlService.createHtmlOutput(html).getBlob(),
"contentType": 'text/html',
"ticket" : JSON.stringify(ticket)
};
an unexpected result occurs:
This comes out the same way for direct coding in the 'content' field with and without .getBlob():
"content" : HtmlService.createHtmlOutput(html).getAs('application/pdf'),
note the createFile line in the code above used to test the pdf. This file is created as expected, of course with the wrong dimensions for label printing (not sure how to convert to pdf with the appropriate margins and page size?): see below
I have now tried to adopt Yuri's ideas; however, the conversion from html to document loses formatting.
var blob = HtmlService.createHtmlOutput(html).getBlob();
var docID = Drive.Files.insert({title: 'temp-label'}, blob, {convert: true}).id
var file = DocumentApp.openById(docID);
file.getBody().setMarginBottom(0).setMarginLeft(0).setMarginRight(0).setMarginTop(0).setPageHeight(79.2).setPageWidth(172.8);
This produces a document looks like this (picture also showing expected output in my hand).
Does anyone have insights into:
How to format the converted pdf to contain appropriate height, width
and margins.
How to convert to pdf in a way that would print correctly.
Here is a minimal code to get a better sense of context https://script.google.com/d/1yP3Jyr_r_FIlt6_aGj_zIf7HnVGEOPBKI0MpjEGHRFAWztGzcWKCJrD0/edit?usp=sharing
I've made the template (80 x 40 mm -- sorry, I don't know your size):
https://docs.google.com/document/d/1vA93FxGXcWLIEZBuQwec0n23cWGddyLoey-h0WR9weY/edit?usp=sharing
And there is the script:
function myFunction() {
// input data
var matName = '<b>testing this to <u>see</u></b> if it <i>actually</i> works <i>e.coli</i>'
var disposeWeek = 'end of semester'
var prepper = 'John Ruppert';
var className = 'Cell and <b>Molecular</b> Biology <u>Fall 2020</u> a few exercises a few exercises a few exercises a few exercises';
var hazards = 'Lots of hazards';
// make a temporary Doc from the template
var copyFile = DriveApp.getFileById('1vA93FxGXcWLIEZBuQwec0n23cWGddyLoey-h0WR9weY').makeCopy();
var doc = DocumentApp.openById(copyFile.getId());
var body = doc.getBody();
// replace placeholders with data
body.replaceText('{matName}', matName);
body.replaceText('{disposeWeek}', disposeWeek);
body.replaceText('{prepper}', prepper);
body.replaceText('{className}', className);
body.replaceText('{hazards}', hazards);
// make Italics, Bold and Underline
handle_tags(['<i>', '</i>'], body);
handle_tags(['<b>', '</b>'], body);
handle_tags(['<u>', '</u>'], body);
// save the temporary Doc
doc.saveAndClose();
// make a PDF
var docblob = doc.getBlob().setName('Label.pdf');
DriveApp.createFile(docblob);
// delete the temporary Doc
copyFile.setTrashed(true);
}
// this function applies formatting to text inside the tags
function handle_tags(tags, body) {
var start_tag = tags[0].toLowerCase();
var end_tag = tags[1].toLowerCase();
var found = body.findText(start_tag);
while (found) {
var elem = found.getElement();
var start = found.getEndOffsetInclusive();
var end = body.findText(end_tag, found).getStartOffset()-1;
switch (start_tag) {
case '<b>': elem.setBold(start, end, true); break;
case '<i>': elem.setItalic(start, end, true); break;
case '<u>': elem.setUnderline(start, end, true); break;
}
found = body.findText(start_tag, found);
}
body.replaceText(start_tag, ''); // remove tags
body.replaceText(end_tag, '');
}
The script just changes the {placeholders} with the data and saves the result as a PDF file (Label.pdf). The PDF looks like this:
There is one thing, I'm not sure if it's possible -- to change a size of the texts dynamically to fit them into the cells, like it's done in your 'autosize.html'. Roughly, you can take a length of the text in the cell and, in case it is bigger than some number, to make the font size a bit smaller. Probably you can use the jquery texfill function from the 'autosize.html' to get an optimal size and apply the size in the document.
I'm not sure if I got you right. Do you need make PDF and save it on Google Drive? You can do in Google Docs.
As example:
Make a new document with your table and text. Something like this
Add this script into your doc:
function myFunction() {
var copyFile = DriveApp.getFileById(ID).makeCopy();
var newFile = DriveApp.createFile(copyFile.getAs('application/pdf'));
newFile.setName('label');
copyFile.setTrashed(true);
}
Every time you run this script it makes the file 'label.pdf' on your Google Drive.
The size of this pdf will be the same as the page size of your Doc. You can make any size of page with add-on: Page Sizer https://webapps.stackexchange.com/questions/129617/how-to-change-the-size-of-paper-in-google-docs-to-custom-size
If you need to change the text in your label before generate pdf or/and you need change the name of generated file, you can do it via script as well.
Here is a variant of the script that changes a font size in one of the cells if the label doesn't fit into one page.
function main() {
// input texts
var text = {};
text.matName = '<b>testing this to <u>see</u></b> if it <i>actually</i> works <i>e.coli</i>';
text.disposeWeek = 'end of semester';
text.prepper = 'John Ruppert';
text.className = 'Cell and <b>Molecular</b> Biology <u>Fall 2020</u> a few exercises a few exercises a few exercises a few exercises';
text.hazards = 'Lots of hazards';
// initial max font size for the 'matName'
var size = 10;
var doc_blob = set_text(text, size);
// if we got more than 1 page, reduce the font size and repeat
while ((size > 4) && (getNumPages(doc_blob) > 1)) {
size = size-0.5;
doc_blob = set_text(text, size);
}
// save pdf
DriveApp.createFile(doc_blob);
}
// this function takes texts and a size and put the texts into fields
function set_text(text, size) {
// make a copy
var copyFile = DriveApp.getFileById('1vA93FxGXcWLIEZBuQwec0n23cWGddyLoey-h0WR9weY').makeCopy();
var doc = DocumentApp.openById(copyFile.getId());
var body = doc.getBody();
// replace placeholders with data
body.replaceText('{matName}', text.matName);
body.replaceText('{disposeWeek}', text.disposeWeek);
body.replaceText('{prepper}', text.prepper);
body.replaceText('{className}', text.className);
body.replaceText('{hazards}', text.hazards);
// set font size for 'matName'
body.findText(text.matName).getElement().asText().setFontSize(size);
// make Italics, Bold and Underline
handle_tags(['<i>', '</i>'], body);
handle_tags(['<b>', '</b>'], body);
handle_tags(['<u>', '</u>'], body);
// save the doc
doc.saveAndClose();
// delete the copy
copyFile.setTrashed(true);
// return blob
return docblob = doc.getBlob().setName('Label.pdf');
}
// this function formats the text beween html tags
function handle_tags(tags, body) {
var start_tag = tags[0].toLowerCase();
var end_tag = tags[1].toLowerCase();
var found = body.findText(start_tag);
while (found) {
var elem = found.getElement();
var start = found.getEndOffsetInclusive();
var end = body.findText(end_tag, found).getStartOffset()-1;
switch (start_tag) {
case '<b>': elem.setBold(start, end, true); break;
case '<i>': elem.setItalic(start, end, true); break;
case '<u>': elem.setUnderline(start, end, true); break;
}
found = body.findText(start_tag, found);
}
body.replaceText(start_tag, '');
body.replaceText(end_tag, '');
}
// this funcion takes saved doc and returns the number of its pages
function getNumPages(doc) {
var blob = doc.getAs('application/pdf');
var data = blob.getDataAsString();
var pages = parseInt(data.match(/ \/N (\d+) /)[1], 10);
Logger.log("pages = " + pages);
return pages;
}
It looks rather awful and hopeless. It turned out that Google Docs has no page number counter. You need to convert your document into a PDF and to count pages of the PDF file. Gross!
Next problem, even if you managed somehow to count the pages, you have no clue which of the cells was overflowed. This script takes just one cell, changes its font size, counts pages, changes the font size again, etc. But it doesn't granted a success, because there can be another cell with long text inside. You can reduce font size of all the texts, but it doesn't look like a great idea as well.

File size increases when converting a Google Sheet into PDF format in Apps script

I have created a script where in Google Sheet is converted to PDF and sent in an email (via Gmail API). for certain records, the PDF size gets increased up to 10 MB (with script) and actually the file size is 130 KB when downloaded manually.
Please find the below syntax which is used to convert sheet to PDF
var blob=DriveApp.getFileById(<<Google Sheet ID>>).getAs('application/pdf');
What could be the possible reason for this issue and How to resolve it?
Your spreadsheet might have many empty cells which get converted into the pdf the way you do it.
I recommend you instead to convert in a more manual way, with the UrlfetchApp - this allows you to specify different options, among others the range you want to convert.
The following sample shows how to export only the data with contents (dataRange) for a spreadsheet that contains onlyone sheet:
function myFunction() {
var token = ScriptApp.getOAuthToken();
var ss = SpreadsheetApp.openById("<<Google Sheet ID>>");
var sheet = ss.getActiveSheet();
var name = ss.getName();
var url = "https://docs.google.com/spreadsheets/d/" + "<<Google Sheet ID>>" + "/export?";
var options = 'exportFormat=pdf&format=pdf' // export format
+ '&size=A4' // paper size
+ '&portrait=true' // orientation
var range = sheet.getDataRange().getA1Notation();
var response = UrlFetchApp.fetch(url + options + '&gid=' + sheet.getSheetId() + "&range=" + range,
{
headers: {
'Authorization': 'Bearer ' + token
},
muteHttpExceptions:true
});
var blob = DriveApp.createFile(response.getBlob().setName(name));
}

Photoshop Automation of alignment of text layer with image

I have never scripted in photoshop before, so I am wondering if this is possible. The following is currently done manually for over than 300 files. The next time round is for 600 files, therefore I am looking into automating it.
Steps:
Make Image Size to 54pixels Hight and 500px Width -- Found that this is doable.
Align Image Left.
Create a text layer and insert text -- Found that this is doable.
Align Text layer 1px to the right of the image.
Trim empty space.
Would appreciate any help and pointers. Thanks.
This script will get you started: Note that in your request you didn't mention what what the original image was going to be and shrinking it to 500 x 54 is going to stretch it one way or another. Step 2, Align the image left, was omitted as you didn't mention what you are aligning this image to. I suspect you are dealing with a large image and what to shrink it down (as long as it's not smaller than 500 x 54) and work from there. I've also omitted stage 4 as I've hard coded the position of the text to be 1 px from the right hand edge (and it vertically centered with Arial font size 18)
Anhyoo.. you should be able to alter the script to your needs.
// set the source document
srcDoc = app.activeDocument;
//set preference units
var originalRulerPref = app.preferences.rulerUnits;
var originalTypePref = app.preferences.typeUnits;
app.preferences.rulerUnits = Units.POINTS;
app.preferences.typeUnits = TypeUnits.POINTS;
// resize image (ignoring the original aspect ratio)
var w = 500;
var h = 54;
var resizeRes = 72;
var resizeMethod = ResampleMethod.BICUBIC;
srcDoc.resizeImage(w, h, resizeRes, resizeMethod)
//create the text
var textStr = "Some text";
createText("Arial-BoldMT", 18.0, 0,0,0, textStr, w-1, 34)
srcDoc.activeLayer.textItem.justification = Justification.RIGHT
//set preference units back to normal
app.preferences.rulerUnits = originalRulerPref;
app.preferences.typeUnits = originalTypePref;
//trim image to transparent width
app.activeDocument.trim(TrimType.TRANSPARENT, true, true, true, true);
// function CREATE TEXT(typeface, size, R, G, B, text content, text X pos, text Y pos)
// --------------------------------------------------------
function createText(fface, size, colR, colG, colB, content, tX, tY)
{
// Add a new layer in the new document
var artLayerRef = srcDoc.artLayers.add()
// Specify that the layer is a text layer
artLayerRef.kind = LayerKind.TEXT
//This section defines the color of the hello world text
textColor = new SolidColor();
textColor.rgb.red = colR;
textColor.rgb.green = colG;
textColor.rgb.blue = colB;
//Get a reference to the text item so that we can add the text and format it a bit
textItemRef = artLayerRef.textItem
textItemRef.font = fface;
textItemRef.contents = content;
textItemRef.color = textColor;
textItemRef.size = size
textItemRef.position = new Array(tX, tY) //pixels from the left, pixels from the top
}
Everything you listed is doable in a script. I suggest you start by reading 'Adobe Intro To Scripting' in your ExtendScript Toolkit program files directory (e.g. C:\Program Files (x86)\Adobe\Adobe Utilities - CS6\ExtendScript Toolkit CS6\SDK\English)
