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.
I have +600 product images on my mac already cut out and catalogued in their own folder. They are all PSD's and I need a script that will do the following.
Grab the name of the folder
Grab all the PSD's in said folder
Combine them in one big PSD in the right order (the filenames are saved sequentially as 1843, 1845, 1846 so they need to open in that order)
save that PSD
save the separate layers as PNG with the name from the folder + _1, _2, _3
I have previous experience in Bash (former Linux user) and tried for hours in Automator but to no success.
Welcome to Stack Overflow. The quick answer is yes this is possible to do via scripting. I might even suggest breaking down into two scripts, one to grab and save the PSDs and the second to save out the layers.
It's not very clear about "combining" the PSDs or about "separate layers, only I don't know if they are different canvas sizes, where you want each PSD to be positioned (x, y offsets & layering) Remember none of use have your files infront of us to refer from.
In short, if you write out pseudo code of what is it you expect your code to do it makes it easier to answer your question.
Here's a few code snippets to get you started:
This will open a folder and retrieve alls the PSDs as an array:
// get all the files to process
var folderIn = Folder.selectDialog("Please select folder to process");
if (folderIn != null)
{
var tempFileList = folderIn.getFiles();
}
var fileList = new Array(); // real list to hold images, not folders
for (var i = 0; i < tempFileList.length; i++)
{
// get the psd extension
var ext = tempFileList[i].toString();
ext = ext.substring(ext.lastIndexOf("."), ext.length);
if (tempFileList[i] instanceof File)
{
if (ext == ".psd") fileList.push (tempFileList[i]);
// else (alert("Ignoring " + tempFileList[i]))
}
}
alert("Files:\n" + fileList.length);
You can save a png with this
function save_png(afilePath)
{
// Save as a png
var pngFile = new File(afilePath);
pngSaveOptions = new PNGSaveOptions();
pngSaveOptions.embedColorProfile = true;
pngSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
pngSaveOptions.matte = MatteType.NONE; pngSaveOptions.quality = 1;
activeDocument.saveAs(pngFile, pngSaveOptions, false, Extension.LOWERCASE);
}
To open a psd just use
app.open(fileRef);
To save it
function savePSD(afilePath)
{
// save out psd
var psdFile = new File(afilePath);
psdSaveOptions = new PhotoshopSaveOptions();
psdSaveOptions.embedColorProfile = true;
psdSaveOptions.alphaChannels = true;
activeDocument.saveAs(psdFile, psdSaveOptions, false, Extension.LOWERCASE);
}
I have a large single pdf document which consists of multiple records. Each record usually takes one page however some use 2 pages. A record starts with a defined text, always the same.
My goal is to split this pdf into separate pdfs and the split should happen always before the "header text" is found.
Note: I am looking for a tool or library using java or python. Must be free and available on Win 7.
Any ideas? AFAIK imagemagick won't work for this. May itext do this? I never used and it's
pretty complex so would need some hints.
EDIT:
Marked Answer led me to solution. For completeness here my exact implementation:
public void splitByRegex(String filePath, String regex,
String destinationDirectory, boolean removeBlankPages) throws IOException,
DocumentException {
logger.entry(filePath, regex, destinationDirectory);
destinationDirectory = destinationDirectory == null ? "" : destinationDirectory;
PdfReader reader = null;
Document document = null;
PdfCopy copy = null;
Pattern pattern = Pattern.compile(regex);
try {
reader = new PdfReader(filePath);
final String RESULT = destinationDirectory + "/record%d.pdf";
// loop over all the pages in the original PDF
int n = reader.getNumberOfPages();
for (int i = 1; i < n; i++) {
final String text = PdfTextExtractor.getTextFromPage(reader, i);
if (pattern.matcher(text).find()) {
if (document != null && document.isOpen()) {
logger.debug("Match found. Closing previous Document..");
document.close();
}
String fileName = String.format(RESULT, i);
logger.debug("Match found. Creating new Document " + fileName + "...");
document = new Document();
copy = new PdfCopy(document,
new FileOutputStream(fileName));
document.open();
logger.debug("Adding page to Document...");
copy.addPage(copy.getImportedPage(reader, i));
} else if (document != null && document.isOpen()) {
logger.debug("Found Open Document. Adding additonal page to Document...");
if (removeBlankPages && !isBlankPage(reader, i)){
copy.addPage(copy.getImportedPage(reader, i));
}
}
}
logger.exit();
} finally {
if (document != null && document.isOpen()) {
document.close();
}
if (reader != null) {
reader.close();
}
}
}
private boolean isBlankPage(PdfReader reader, int pageNumber)
throws IOException {
// see http://itext-general.2136553.n4.nabble.com/Detecting-blank-pages-td2144877.html
PdfDictionary pageDict = reader.getPageN(pageNumber);
// We need to examine the resource dictionary for /Font or
// /XObject keys. If either are present, they're almost
// certainly actually used on the page -> not blank.
PdfDictionary resDict = (PdfDictionary) pageDict.get(PdfName.RESOURCES);
if (resDict != null) {
return resDict.get(PdfName.FONT) == null
&& resDict.get(PdfName.XOBJECT) == null;
} else {
return true;
}
}
You can create a tool for your requirements using iText.
Whenever you are looking for code samples concerning (current versions of) the iText library, you should consult iText in Action — 2nd Edition the code samples from which are online and searchable by keyword from here.
In your case the relevant samples are Burst.java and ExtractPageContentSorted2.java.
Burst.java shows how to split one PDF in multiple smaller PDFs. The central code:
PdfReader reader = new PdfReader("allrecords.pdf");
final String RESULT = "record%d.pdf";
// We'll create as many new PDFs as there are pages
Document document;
PdfCopy copy;
// loop over all the pages in the original PDF
int n = reader.getNumberOfPages();
for (int i = 0; i < n; ) {
// step 1
document = new Document();
// step 2
copy = new PdfCopy(document,
new FileOutputStream(String.format(RESULT, ++i)));
// step 3
document.open();
// step 4
copy.addPage(copy.getImportedPage(reader, i));
// step 5
document.close();
}
reader.close();
This sample splits a PDF in single-page PDFs. In your case you need to split by different criteria. But that only means that in the loop you sometimes have to add more than one imported page (and thus decouple loop index and page numbers to import).
To recognize on which pages a new dataset starts, be inspired by ExtractPageContentSorted2.java. This sample shows how to parse the text content of a page to a string. The central code:
PdfReader reader = new PdfReader("allrecords.pdf");
for (int i = 1; i <= reader.getNumberOfPages(); i++) {
System.out.println("\nPage " + i);
System.out.println(PdfTextExtractor.getTextFromPage(reader, i));
}
reader.close();
Simply search for the record start text: If the text from page contains it, a new record starts there.
Apache PDFBox has a PDFSplit utility that you can run from the command-line.
If you like Python, there's a nice library: PyPDF2. The library is pure python2, BSD-like license.
Sample code:
from PyPDF2 import PdfFileWriter, PdfFileReader
input1 = PdfFileReader(open("C:\\Users\\Jarek\\Documents\\x.pdf", "rb"))
# analyze pdf data
print input1.getDocumentInfo()
print input1.getNumPages()
text = input1.getPage(0).extractText()
print text.encode("windows-1250", errors='backslashreplacee')
# create output document
output = PdfFileWriter()
output.addPage(input1.getPage(0))
fout = open("c:\\temp\\1\\y.pdf", "wb")
output.write(fout)
fout.close()
For non coders PDF Content Split is probably the easiest way without reinventing the wheel and has an easy to use interface: http://www.traction-software.co.uk/pdfcontentsplitsa/index.html
hope that helps.
activeDocument.fitArtboardToSelectedArt()
When calling this command, AI crashes on AI 5.1/6 32bit and 64bit versions. I can use the command from the menu. Has anyone encountered this? does anyone know of a work around?
The full code.
function exportFileToJPEG (dest) {
if ( app.documents.length > 0 ) {
activeDocument.selectObjectsOnActiveArtboard()
activeDocument.fitArtboardToSelectedArt()//crashes here
activeDocument.rearrangeArtboards()
var exportOptions = new ExportOptionsJPEG();
var type = ExportType.JPEG;
var fileSpec = new File(dest);
exportOptions.antiAliasing = true;
exportOptions.qualitySetting = 70;
app.activeDocument.exportFile( fileSpec, type, exportOptions );
}
}
var file_name = 'some eps file.eps'
var eps_file = File(file_name)
var fileRef = eps_file;
if (fileRef != null) {
var optRef = new OpenOptions();
optRef.updateLegacyText = true;
var docRef = open(fileRef, DocumentColorSpace.RGB, optRef);
}
exportFileToJPEG ("output_file.jpg")
I can reproduce the bug with AI CS5.
It seems that fitArtboardToSelectedArt() takes the index of an artboard as an optional parameter. When the parameter is set, Illustrator doesn't crash. (probably a bug in the code handling the situation of no parameter passed)
As a workaround you could use:
activeDocument.fitArtboardToSelectedArt(
activeDocument.artboards.getActiveArtboardIndex()
);
to pass the index of the active artboard with to the function. Hope this works for you too.
Also it's good practice to never omit the semicolon at the end of a statement.
Is is possible to remove or hide a layer from a PDF using ABCPdf or another framework?
The following C# example shows how layer 2 of page 1 can be deleted:
Doc theDoc = new Doc();
theDoc.Read("source.pdf");
int thePages = theDoc.GetInfoInt(theDoc.Root, "Pages");
int thePage = theDoc.GetInfoInt(thePages, "Page 1");
int theLayer = theDoc.GetInfoInt(thePage, "Content 2");
theDoc.Delete(theLayer);
Or perhaps you were looking for the Flatten() function?
ABCpdf contains an Example project called OCGLayers. This project shows you how to identify and redact all the items in a layer.
For example:
Properties props = Properties.FromDoc(_doc, false);
Page page = (Page)_doc.ObjectSoup[_doc.Page];
Reader reader = Reader.FromPage(props, page);
List<OptionalContent.Layer> layers = reader.GetLayers();
foreach (OptionalContent.Layer layer in layers) {
if (layer.Visible == false) {
if (reader == null)
reader = Reader.FromPage(props, page);
Reader.Redact(ref reader, layer);
}
}
UpdateLayers();
UpdatePreview();
