same problems... there is a solution?
Edit: I found the problem when i scanned trough the code i think.
When the PDFTextField.setText('string')
command i called it markes the field as "dirty" that somehow tells the library that the field needs updating in styling.
If you tried to add the font by yourself with PDFDocument.embedFont(font)
and then try to update the apperance with PDFTextField.updateAppearances()
it still marks it as dirty and changes the font.
The solution i found was that the updateAppearances(font)
command marks it as clean again so as long as you call the updateAppearances()
after you call the setText()
the field is marked as clean and the program wont change your font
I dont think i have the coding skills neccessary to make a fix for it but this is a half solution until someone smarter can fix it :)
// Imports
const { PDFDocument } = require('pdf-lib')
const { readFile } = require('fs/promises')
const fontkit = require('@pdf-lib/fontkit')
// Import pdf document
const document = await PDFDocument.load(await readFile('/path/to/file.pdf'))
// Create a custom font
document.registerFontkit(fontkit)
const custonFont = await document.embedFont(await readFile('/custom/font.ttf'))
// Get form and field
const form = document.getForm()
const titleField = form.getTextField('form identifier')
// Set the text and after update to font
titleField.setText(object.title)
titleField.updateAppearances(custonFont)
I was doing textField.updateAppearances(font)
and then textField.setAlignment(alignment)
. This caused the same problem. So I believe the final word is: just use updateAppearances
after you did all setters
I do not see the needed font even after the updateAppearances
in the pdf the field is marked as using the right font, but opening the file I do not see the right font.
I'm having similar problem. Another issue mentioned it working only after form.flatten()
is called. Unfortunately this makes the fields uneditable (additionally I am facing issue where text is garbled when using {subset: true}
when embedding the font, but it's probably not related to use of flatten).
I'm having the same issue. Thanks coffedahl for the workaround.
FYI: calling form.updateFieldAppearances(pdfFont)
on the entire form also solved the issue and maybe easier to achieve in some cases.
Hello,
Facing same issue, i don't understand why if i have a font already embedded and used for the whole PDF and its forms fields i have to embed the same font again, this is clearly a BUG. Anyone knows how to force form text fields to use the same font and style already set for the whole PDF and its form fields without embed another one? The thing about dirty and clear is riducolous, why the lib should force using Helvetica when form fields already have their style set?
Hi there, thanks for creating the best PDF library on the internet! I ran into some issues trying to fill text fields on my AcroForm
What were you trying to do?
I tried to use PDF-LIB
form.getTextField('dateTaken').setText('hello this is my text')
to set some text fields on my form. But the fonts I configured in Adobe Acrobat Pro is ignored.I created a form using Adobe Acrobat Pro When creating the fields in Adobe Acrobat Pro I can edit the text field properties and set a font.
When I fill the form in Adobe Acrobat it fills correctly, the font size, color, and font is maintained:
But when I use the following code:
And save the pdf, the font is not maintained:
How did you attempt to do it?
What actually happened?
The generated PDF shows the correct text, the correct font color and font size, but not the correct font.
All fonts are embedded:
What did you expect to happen?
I expected the text fields to be in the correct font, like when I filled the form out using Adobe Acrobat.
How can we reproduce the issue?
