            Bug ID: 60452
           Summary: wineps.drv: Alpha-channel transparency lost when
                    printing PDF signature overlays (Foxit Reader)
           Product: Wine
           Version: 11.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wineps.drv
          Assignee: [e-mail]
          Reporter: [e-mail]
  Target Milestone: ---
      Distribution: ---

TOP: A screenshot of the PDF as displayed inside Foxit (showing the tick
correctly over the text). BOTTOM: The resulting printed PDF showing the opaque
block covering the text.

When printing a PDF containing a dynamic/validated digital signature in Foxit
Reader through a CUPS virtual printer (CUPS-PDF), the transparency layer of the
signature tick is lost.

Instead of rendering with alpha transparency over the text, the
checkmark/overlay prints as an opaque block that covers the text underneath.

Steps to reproduce:
1. Open a signed PDF in Foxit Reader under Wine.
2. Verify the signature so the green validation tick appears.
3. Print the document to CUPS-PDF.
4. Inspect the resulting PDF: the tick/overlay is opaque and covers the
underlying text.

Expected behavior:
The overlay should retain transparency and render over/under document text
identically to screen rendering.
