TIFF image Format

Copy all your Qt plugins too to the target PC.
Check the documentation:

I didn't added qtiff.lib in vcproj on my DEV PC , and it still working .

Qt finds the plugins by itself.

But they need to be there.

I coped complete QT directory into target PC , added qtiffd4.lib into vsproj , but still I can open only PNG files.

Hi,

Have you copied the "plugins" directory inside the target directory?

YourAppDirectory
|----your files(exe, ...)
|----plugins
|----imageformats
|----------------qt plugins dlls(like "qtiff4.dll")

I have 2 PC :
1. Dev1 PC with full QT installation. (working fine , QT finds plugins).
2. Dev2 PC same as Dev1 PC ( same visual studio.. ) no QT installed ( QT used as external library ) -> can't find plugins.

In both PC there is same vsproj file and env variebles.

You have to put qtiff4.dll in folder imageformats, that should be a subfolder of your application folder as ^NyAw^ said.
And by the way, QT = Quick Time, and Qt = this nice library
