Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect)

Description

[Dominik]

Attachment: issue.zip

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

With the last release of Firefox the support for PDF Form Filling was enabled by default (pdfjs.renderInteractiveForms = true). There are now rendering issues and printing issues with the text size / font size.

I have attached several screenshots, PDF and the original PDF-Document.

Steps:

1. Default firefox settings: pdfjs.renderInteractiveForms = true

2. Open attached "Original_Document.pdf" in Firefox 83.0 (Windows 10 Pro 20H2, 100% dpi scaling)

3. Print the document or use "Microsoft Print to PDF"

4. keep the window/tab

5. Change => pdfjs.renderInteractiveForms = false

6. Open again in new tab the "Original_Document.pdf"

7. Compare rendering on screen with previous tab (renderInteractiveForms = true) -> font size is different

8. Print the document or use "Microsoft Print to PDF"

9. compare both printed versions => the first document (renderInteractiveForms = true) as a very large text / font size, compare to second print (expected result)

10. Open "Original_Document.pdf" with Chrome / Acrobat Reader

11. Print document for both documents => equal to second print ( pdfjs.renderInteractiveForms = false) == expected result

I have attached screenshots and printed results (Microsoft Print to PDF) for all versions.

Actual results:

Some textfields are rendered with a different size / printed with a very high size

actual result (pdfjs.renderInteractiveForms = true):

1. Firefox_fillable.png
2. Firefox_fillable_Printed.pdf

Expected results:

Expected (Firefox => pdfjs.renderInteractiveForms = false):

Firefox_fillable_disabled.png
Firefox_fillable_disabled_Printed.pdf
Acrobat_reader.png
Acrobat_reader_printed.pdf
Chrome.png
Chrome_printed.pdf
