[TC8b2 - x32] QuickView overlay - transparent PNG

fenix_productions · Post by *fenix_productions » 2011-09-29, 18:00 UTC

TC seems to not refresh memory after transparent images are shown.

Steps to reproduce:
1. create folder with few transparent PNG images,
2. add few normal images,
3. activate QuickView (Ctrl+Q),
4. navigate through images using arrows.

Bug:
Sometimes after transparent image display, next image is written with previous one on the top.

Please take a look at movie:

Notes:
WinXP SP3, completely new configuration file (/i=test.ini).

I can confirm this, when no plugin, but GDI Plus is used for viewing the files,

I cannot reproduce it. Can you give me some test images and instructions, please?

1. Download and unpack somewhere:

2. Ctrl+Q on first file
3. navigate (using arrows) through files: all way down, all way up, repeat.

Christian, there are reports on Russian board that some other formats with transparent background also affected (GIF, EMF, WMF). Please try theese samples in QV mode. Only x32 is affected.

Just tested it - Lister is also able to show bug (when images are switched by P/N).

BTW, x32 and x64 are unable to show specific images from it (x32 can't display one of WMFs, x64 - none of WMFs and EMFs in my Win7sp1Pro). I set WmfAllowed=2 during tests.

GIF will be supported in beta 4.

WMF and EMF are not supported by Lazarus, probably because they are not portable, or because of the risk to have another bug in the play functions. Currently I don't plan to port them to 64-bit.

The transparent WMF/EMF problem already exists in TC 7.56a. I will check whether I can handle that somehow.

This should work now in beta 4, please test it!

WMF and EMF have not been changed, I will probably not touch this code.

Cannot reproduce in beta4. Seems fixed.

Seems to be fixed in TC 8.0b4 x64 and 32bit
