Bug ID: 150076
Summary: PDF image used as background in draw is exported as
(low resolution) image when doing a PDF export
Product: LibreOffice
Version: 7.3.4.2 release
Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Printing and PDF export
Assignee: [email protected]
Reporter: [email protected]
Description:
When a PDF image is used for the background of a draw document and the document
is then exported as PDF, the background is included in the PDF document as a
low resolution bitmap, rather than as a vector image.
This is very much undesirable:
- the possibility to cut/copy text is lost
- the resolution is poor (96dpi)
- the vector quality of the image is lost
- in some cases the resulting PDF file gets larger than it could (this is
limited by the very poor resolution of the bitmap, though)
Note that using PDF images as background represents a frequently adopted
workflow for filling in forms that have been made available in PDF, but not as
PDF forms.
Steps to Reproduce:
1. Open libreoffice draw
2. Insert as the background image a PDF file
3. Export to PDF
4. Open the resulting PDF file with a viewer or use some utility such as
pdfimages to export the bitmaps that are present in the PDF file
Actual Results:
The background image is present in the PDF file as a 96dpi bitmap
Expected Results:
The background image should be maintained in vector format if it is in vector
format to start with.
Reproducible: Always
