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)

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.
I have a section of my PDF in which I need to use one font for its unicode symbol and the rest of the paragraph should be a different font. (It is something like "1. a 2. b 3. c" where "1." is the unicode symbol/font and "a" is another font) I have followed the method Bruno describes here: iText 7: How to build a paragraph mixing different fonts? and it works fine to generate the PDF. The issue is that the file size of the PDF goes from around 20MB to around 100MB compared to using only one font and one Text element. This section is used repeatedly in the document thousands of times. I am wondering if there is a way to reduce the impact of switching fonts or to reduce the file size of the entire document in some way.
Style creation pseudocode:
Style style1 = new Style();
Style style2 = new Style();
PdfFont font1 = PdfFontFactory.createFont(FontProgramFactory.createFont(fontFile1), PdfEncodings.IDENTITY_H, true);
style1.setFont(font1).setFontSize(8f).setFontColor(Color.DARK_GRAY);
PdfFont font2 = PdfFontFactory.createFont(FontProgramFactory.createFont(fontFile2), "", false);
style2.setFont(font2).setFontSize(8f).setFontColor(Color.DARK_GRAY);
Writing text/paragraph pseudocode:
Div div = new Div().setPaddingLeft(3).setMarginBottom(0).setKeepTogether(true);
Paragraph paragraph = new Paragraph();
loop up to 25 times: {
Text unicodeText = new Text(unicodeSymbol + " ").addStyle(style1);
paragraph.add(unicodeText);
Text plainText = new Text(plainText + " ").addStyle(style2);
paragraph.add(plainText);
}
div.add(paragraph);
This writing of text/paragraph is done thousands of times and makes up most of the document. Basically the document consists of thousands of "buildings" that have corresponding codes and the codes have categories. I need to have the index for the category as the unicode symbol and then all of the corresponding codes within the paragraph for the building.
Here is reproducable code:
float offSet = 50;
Integer leading = 10;
DateFormat format = new SimpleDateFormat("yyyy_MM_dd_kkmmss");
String formattedDate = format.format(new Date());
String path = "/tmp/testing_pdf_"+formattedDate + ".pdf";
File targetPdfFile = new File(path);
PdfWriter writer = new PdfWriter(path, new WriterProperties().addXmpMetadata());
PdfDocument pdf = new PdfDocument(writer);
pdf.setTagged();
PageSize pageSize = PageSize.LETTER;
Document document = new Document(pdf, pageSize);
document.setMargins(offSet, offSet, offSet, offSet);
byte[] font1file = IOUtils.toByteArray(FileUtility.getInputStreamFromClassPath("fonts/Garamond-Premier-Pro-Regular.ttf"));
byte[] font2file = IOUtils.toByteArray(FileUtility.getInputStreamFromClassPath("fonts/Quivira.otf"));
PdfFont font1 = PdfFontFactory.createFont(FontProgramFactory.createFont(font1file), "", true);
PdfFont font2 = PdfFontFactory.createFont(FontProgramFactory.createFont(font2file), PdfEncodings.IDENTITY_H, true);
Style style1 = new Style().setFont(font1).setFontSize(8f).setFontColor(Color.DARK_GRAY);
Style style2 = new Style().setFont(font2).setFontSize(8f).setFontColor(Color.DARK_GRAY);
float columnGap = 5;
float columnWidth = (pageSize.getWidth() - offSet * 2 - columnGap * 2) / 3;
float columnHeight = pageSize.getHeight() - offSet * 2;
Rectangle[] columns = {
new Rectangle(offSet, offSet, columnWidth, columnHeight),
new Rectangle(offSet + columnWidth + columnGap, offSet, columnWidth, columnHeight),
new Rectangle(offSet + columnWidth * 2 + columnGap * 2, offSet, columnWidth, columnHeight)};
document.setRenderer(new ColumnDocumentRenderer(document, columns));
for (int j = 0; j < 5000; j++) {
Div div = new Div().setPaddingLeft(3).setMarginBottom(0).setKeepTogether(true);
Paragraph paragraph = new Paragraph().setFixedLeading(leading);
// StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < 26; i++) {
paragraph.add(new Text("\u3255 ").addStyle(style2));
paragraph.add(new Text("test ").addStyle(style1));
// stringBuilder.append("\u3255 ").append(" test ");
}
// paragraph.add(stringBuilder.toString()).addStyle(style2);
div.add(paragraph);
document.add(div);
}
document.close();
In creating the reproducible code I have found this this is related to the document being tagged. If you remove the line that marks it as tagged it reduces the file size greatly.
You can also reduce the file size by using the commented out string builder with one font instead of two. (Comment out the two "paragraph.add"s in the for-loop) This mirrors the issue I have in my code.
The problem is not in fonts themselves. The issues comes from the fact that you are creating a tagged PDF. Tagged documents have a lot of PDF objects in them that need a lot of space in the file.
I wasn't able to reproduce your 20MB vs 100MB results. On my machine whether with one font or with two fonts, but with two Text elements, the resultant file size is ~44MB.
To compress file when creating large tagged documents, you should use full compression mode which compresses all PDF objects, not only streams.
To activate full compression mode, create a PdfWriter instance with WriterProperties:
PdfWriter writer = new PdfWriter(outFileName,
new WriterProperties().setFullCompressionMode(true));
This setting reduced the file size for me from >40MB to ~5MB.
Please note that you are using iText 7.0.x while 7.1.x line has already been released and is now the main line of iText, so I recommend that you update to the latest version.
Requirement:
A large image (dynamic) needs to be split and shown in PDF pages. If image can't be accomodated in one page then we need to add another page and try to fit the remaining portion and so on.
So far I am able to split the image in multiple pages, however it appears that they are completely ignoring the margin values and so images are shown without any margins.
Please see below code:
string fileStringReplace = imageByteArray.Replace("data:image/jpeg;base64,", "");
Byte[] imageByte = Convert.FromBase64String(fileStringReplace);
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(imageByte);
float w = image.ScaledWidth;
float h = image.ScaledHeight;
float cropHeight = 1500f;
iTextSharp.text.Rectangle page = new iTextSharp.text.Rectangle(1150f, cropHeight);
var x = page.Height;
Byte[] created;
iTextSharp.text.Document document = new iTextSharp.text.Document(page, 20f, 20f, 20f, 40f); --This has no impact
using (var outputMemoryStream = new MemoryStream())
{
PdfWriter writer = PdfWriter.GetInstance(document, outputMemoryStream);
writer.CloseStream = false;
document.Open();
PdfContentByte canvas = writer.DirectContentUnder;
float usedHeights = h;
while (usedHeights >= 0)
{
usedHeights -= cropHeight;
document.SetPageSize(new iTextSharp.text.Rectangle(1150f, cropHeight));
canvas.AddImage(image, w, 0, 0, h, 0, -usedHeights);
document.NewPage();
}
document.Close();
created = outputMemoryStream.ToArray();
outputMemoryStream.Write(created, 0, created.Length);
outputMemoryStream.Position = 0;
}
return created;
I also tried to set margin in the loop by document.SetMargins() - but that's not working.
You are mixing different things.
When you create margins, be it while constructing the Document instance or by using the setMargins() method, you create margins for when you let iText(Sharp) decide on the layout. That is: the margins will be respected when you do something like document.Add(image).
However, you do not allow iText to create the layout. You create a PdfContentByte named canvas and you decide to add the image to that canvas using a transformation matrix. This means that you will calculate the a, b, c, d, e, and f value needed for the AddImage() method.
You are supposed to do that Math. If you want to see a margin, then the values w, 0, 0, h, 0, and -usedHeights are wrong, and you shouldn't blame iTextSharp, you should blame your lack of insight in analytical geometrics (that's the stuff you learn in high school at the age of 16).
This might be easier for you:
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(imageByte);
float w = image.ScaledWidth;
float h = image.ScaledHeight;
// For the sake of simplicity, I don't crop the image, I just add 20 user units
iTextSharp.text.Rectangle page = new iTextSharp.text.Rectangle(w + 20, h + 20);
iTextSharp.text.Document document = new iTextSharp.text.Document(page);
PdfWriter writer = PdfWriter.GetInstance(document, outputMemoryStream);
// Please drop the line that prevents closing the output stream!
// Why are so many people making this mistake?
// Who told you you shouldn't close the output stream???
document.Open();
// We define an absolute position for the image
// it will leave a margin of 10 to the left and to the bottom
// as we created a page that is 20 user units to wide and to high,
// we will also have a margin of 10 to the right and to the top
img.SetAbsolutePosition(10, 10);
document.Add(Image);
document.Close();
Note that SetAbsolutePosition() also lets you take control, regardless of the margins, as an alternative, you could use:
iTextSharp.text.Image image = iTextSharp.text.Image.GetInstance(imageByte);
float w = image.ScaledWidth;
float h = image.ScaledHeight;
// For the sake of simplicity, I don't crop the image, I just add 20 user units
iTextSharp.text.Rectangle page = new iTextSharp.text.Rectangle(w + 20, h + 20);
iTextSharp.text.Document document = new iTextSharp.text.Document(page, 10, 10, 10, 10);
PdfWriter writer = PdfWriter.GetInstance(document, outputMemoryStream);
// Please drop the line that prevents closing the output stream!
// Why are so many people making this mistake?
// Who told you you shouldn't close the output stream???
document.Open();
// We add the image to the document, and we let iTextSharp decide where to put it
// As there is just sufficient space to fit the image inside the page, it should fit,
// But be aware of the existence of a leading; that could create side-effects
// such as forwarding the image to the next page because it doesn't fit vertically
document.Add(Image);
document.Close();
How do I add a drop shadow (with defined distance, size etc) using Photoshop scripting?
Current JS Code
var fontSize = 14;
var fontName = "Arial-Bold"; // NB: must be postscript name of font!
// This is the colour of the text in RGB
//Click foreground colour in Photoshop, choose your colour and read off the RGB values
//these can then be entered below.
var textColor = new SolidColor();
textColor.rgb.red = 255;
textColor.rgb.green =255;
textColor.rgb.blue = 255;
var newTextLayer = doc.artLayers.add();
newTextLayer.kind = LayerKind.TEXT;
newTextLayer.textItem.size = fontSize;
newTextLayer.textItem.font = fontName;
newTextLayer.textItem.contents = ++Count;
newTextLayer.textItem.color = textColor;
newTextLayer.textItem.kind = TextType.PARAGRAPHTEXT;
newTextLayer.textItem.height = fontSize;
newTextLayer.textItem.width = doc.width -20;
//The line below is the text position (X Y) IE; 10 Pixels Right 10 Pixels Down
newTextLayer.textItem.position = Array(10, 12);
// Can be RIGHTJUSTFIED LEFTJUSTIFIED CENTERJUSTIFIED
newTextLayer.textItem.justification=Justification.CENTERJUSTIFIED;
I believe there is no API function for this.
The best you can do is to use Scriptlistner.
The code that it generates then can be used in your script.
Here are some similar discussion with Scriptlistner-generated code:

Whether I use XTextFormatter or not, I get the same error about the LayoutRectangle having to have a height of 0 or something like this.
new PdfSharp.Drawing.Layout.XTextFormatter(_gfx).DrawString(text
, new PdfSharp.Drawing.XFont(fontName, fontSize, (PdfSharp.Drawing.XFontStyle)fontStyle)
, new PdfSharp.Drawing.XSolidBrush(PdfSharp.Drawing.XColor.FromArgb(foreColour))
, new PdfSharp.Drawing.XRect(new PdfSharp.Drawing.XPoint(xPos, yPos), new PdfSharp.Drawing.XPoint(xLimit, yLimit))
, PdfSharp.Drawing.XStringFormats.Default);
fontStyle is of type System.Drawing.FontStyle
foreColour is of type System.Drawing.Color
I have already predefined _gfx from a PdfPage with Orientation = Landscape, Size = Letter
xPos and yPos are parameters of type double, the same with xLimit and yLimit.
I get the runtime error that the
LayoutRectangle must have a height of
zero (0)...
Per definition a rectangle is meant to have a height, otherwise call it a line! I don't get it!...
I tried with the XGraphics.DrawString() method directly, and I get the same error. It seems that I can't use the LayoutRectangle but have to manage that the text fit within the desired area manually.
var textFont = new PdfSharp.Drawing.XFont(fontName, fontSize, (PdfSharp.Drawing.XFontStyle)fontStyle);
while (xPos + _gfx.MeasureString(text, textFont).Width > xLimit)
textFont = new PdfSharp.Drawing.XFont(fontName, --fontSize, (PdfSharp.Drawing.XFontStyle)fontStyle);
while (yPos + _gfx.MeasureString(text, textFont).Height > yLimit && fontSize > 0)
textFont = new PdfSharp.Drawing.XFont(fontName, --fontSize, (PdfSharp.Drawing.XFontStyle)fontStyle);
_gfx.DrawString(text
, textFont
, new PdfSharp.Drawing.XSolidBrush(PdfSharp.Drawing.XColor.FromArgb(foreColour))
, new PdfSharp.Drawing.XPoint(xPos, yPos));
Though the yPos variable value is the exact same value!
*yPos = Page.Height * .4093, either 40,93% of the page's height.*
Herewith an example of what I try to do:
"Hello World!" "Hello
World!"
And here is what I get:
"Hello World!"
"Hello World!"
And because of different printing area limits and size of the font and the different font style, I can't just write these into one simple sentence including the correct number of spaces.
Quoting error messages exactly helps others to help you.
The error message reads:
DrawString: With XLineAlignment.BaseLine the height of the layout rectangle must be 0.
The text will be aligned at a line, therefore height must be 0. Yes, that's a line.
Use a different alignment if you specify a rectangle.
The TextLayout sample shows how to format text.
The Graphics sample also shows how to layout text (single lines of text, no automatic line breaks; the technique shown in the TextLayout sample handles line breaks automatically using the XTextFormatter class).
While trying to figure out how text positioning works with PdfSharp, I noticed that the DrawString() method writes on top of the Y coordinate that we specify.
If I wish to write at (0, 100)(x, y), this points to the lower-left corner while I thought this was the top-left corner coordinates. As a result, the text string Y coordinate that I should have specified is 100 + string.Height * .6.
PdfDocument pdfDoc = new PdfDocument();
PdfPage pdfPage = new pdfPage();
pdfPage.Size = PageSize.Letter;
pdfPage.Orientation = Orientation.Landscape;
pdfDoc.Pages.Add(pdfPage);
double posX = 0;
double posY = pdfPage.Height * .4093;
string helloString = "Hello"
string worldString = "World!"
XFont helloFont = new XFont("Helvetica", 25, XFontStyle.Regular);
XFont worldFont = new XFont("Helvetica", 270, XFontStyle.Bold);
using(var pdfGfx = XGraphics.FromPdfPage(pdfPage)) { // assuming the default Point UOM
XSize helloStringSize = pdfGfx.MeasureString(helloString, helloFont);
XSize worldStringSize = pdfGfx.MeasureString(worldString, worldFont);
pdfGfx.DrawString(helloString
, helloFont
, XBrushes.Black
, posX
, posY + helloStringSize.Height * .6
, XStringFormats.Default);
pdfGfx.DrawString(worldString
, worldFont
, XBrushes.Black
, pdfPage.Width * .3978
, posY + (worldStringSize.Height + helloStringSize.Height) * .6
, XStringFormats.Default);
}
You'll perhaps wonder why I only add 60% of the string size when I want to get my string written below my Y coordinate? That is because the full height of the font includes somekind of leap on top. So, the computing result will not be what is expected. On the other hand, you don't have to care about a leap if you need one. In my particular case, I don't require leap, so I must take it off the string's height.
If you feel like my explanation needs more accurate details, please feel free to either add them as comments or keep me informed so that I may include them.
Thanks!
