Editor corrupts some vector graphics #204

AlisterH commented 3 months ago

Open this in the editor empty_A4_logo.pdf
Tools>Editor>Edit page content, and straight away the logo turns into a solid rectangle
Do anything, and save the pdf.
Open the output file, e.g. empty_A4_logo_edited.pdf, and you will see the logo is still a solid rectangle.

Note that I will probably redact this ticket at some stage to remove the example files.

I will have a look on it tomorrow.

@AlisterH, I am afraid, this is not possible to solve. The problem is, that path is painted using the clipping path, which is not supported by editor. I do not know how to solve it. Any advices?

I don't know enough to comment other than that as a user there is a continuum of behaviour from most to least preferrable, something like this:

Implement full support for it (surely this is desirable long term).
Allow editing other properties of it without altering the clipping path.
Allow editing other page content without altering unsupported objects like this.
Warn the user about it and that it could cause a problem.
