Bug ID: 114705
Summary: Images distorted after export to PDF from Writer with
enabled JPG-compression if OpenGL ist active
Product: LibreOffice
Version: 5.4.4.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Printing and PDF export
Assignee: libreoffice-***@lists.freedesktop.org
Reporter: ***@gmx.de

Description:
If I export a writer document with embedded images to a pdf, some of them get
distorted using the standard-export-settings. If I deactivate the
jpg-compression inside the export dialog, the images get not distorted. The
same happens if I let the jpg-compression activated but deactivate OpenGL. The
bug was adressed in further versions and was announced to be fixed
(https://www.bitblokes.de/libreoffice-5-1-rc1-ist-verfuegbar-kuemmert-sich-um-schusterjungen-und-hurenkinder/,
" Weiterhin sollen Bilder bei einem PDF-Export nicht mehr verzerrt werden, wenn
OpenGL aktiviert ist"), but it seems like it still exists in 5.3.7 and 5.4.4.

Steps to Reproduce:
1. Create a writer document with embedded images
2. Export to pdf with standard settings
3. Export to pdf with deactivated OpenGL or without jpeg-compresion

Actual Results:
It seems like not all images get distorted, at the moment I don't know why some
are and some not. But I seems that bigger images are affected.

Expected Results:
Images should be not distorted


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

PDF-Output with deactivated jpeg-compression

You get the same result with activated jpg-compression and deactivated OpenGl.

tdf#103803 change from BGRA to RGBA color arrangement on Windows
BGRA is native color arrangement on Windows however some intel
drivers have problems with large textures if they read from a
BGRA buffer. So with this commit we switch to RGBA color
arrangement. This shouldn't cause much performance differences,
but we need to convert from RGBA to BGRA when printing.

+ fix: wrong GL format for RGBA image buffers
