2635Image bleed-thorughs, GDI vs. GDI+
- Jun 2, 2004Hello!
I am trying to use ZT 7.11 on a WinXP system (SP1 + 17 hotfixes). In some
applications, when dealing with rather large images, these images are
paitned onto the screen directly bypassing the ZT magnifying mechanism.
I found an explanation for this in the AI*AI knowledge base. The problem is
a new technique calles GDI+ to paint large images faster than ever... They
recommend to install the latest service pack for windows. But I already did
this when setting up the system. If I work with rather small images, no
bleed-thorugh can be observed.
I make a full screen screenshot and past it into irfanview. (latest edition)
The programm resizes its window to full-screen to fit the image into its
window. Images taht large are painted directly onto the screen (unmagnified,
no color tereatment). When I make a screenshot of say just a small dialog
box and paste that into irfanview, the program appenrently does not use GDI+
but GDI or something similar. In this case, the screen is okay, everything
is magnified and color treated as it should.
There doesn't seem to be a way to disable GDI+ within windows in order to
prevent each and every program from using it in the first place. Or do you
know a way to do that? I tried disabling or lowering hardware acceleration,
but this only leads ZT to not being able to track the mouse any longer.
Menus are still tracked... Awesome.
The same image bleed-through occurs in Word2000 or actually any app that
uses images taht have to be painted/repainted.
Have you got any suggestions for me?
Thank you very much in advance!
