Bug ID: 148211
Summary: WRITER: Image cropping properties does not work when
source image is a linked (not embedded) PDF
Product: LibreOffice
Version: 7.2.6.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
When inserting images (by linking or embedding), we can choose from a variety
of formats, including PDF. By going to the inserted image properties, we can
crop the image shown without cropping the image file by itself.
However, if the inserted image is a PDF file that was linked and not embedded
into the document, the cropping properties just mess the images show and it is
not possible to crop properly the image.
Steps to Reproduce:
1. Create a new text document and insert by linking/embedding an image with the
PDF format attached on this bug report;
2. Open the shortcut menu on the PDF image, go to Properties, Crop, and change
the crop top and bottom values so the image shows only the "PDF" text and not
the paper sheet (don't need to be perfect, just to see what will happen next);
3. Save the text document;
4. Reopen the text document;
5. Go to the image properties to change the crop settings there, for example
remove the top and bottom crop (reset to zero).
Actual Results:
If the step 1 was chosen to link the PDF image, the end result is a distorted
image.
Expected Results:
The PDF image should not be distorted, no matter what inserting method was
chosen on the step 1 (linking or embedding).
Reproducible: Always
User Profile Reset: Yes
Additional Info:
I found that when LibreOffice saves a text document with a PDF image embedded,
the file inside is changed to PNG instead to being kept as a PDF or changed to
a vector format as SVG. So maybe this bug happens because of the image filter
making a conversion error.
Also, as PDFs can be converted to SVGs in a visually identical image, even if
the metadata or embedded text is lost, maybe this bug can be fixed by changing
the way LibreOffice interacts with inserted (linked or embedded) PDFs.
