View Full Version : displaying .gif

12th October 2009, 14:28

I'm using Qt 4.5.2 on Vista and I have an application to show images.
On my machine I can display .gif as well as .jpg and .png and so on.
If I make a release version and run the app on a other machine(without Qt installed),
I cannot view .gif any longer, but still can .jpg .png ....

I've already copied all dlls I could find to my release directory on usb-stick, but that didnt help..

What else can I do?

best regards

Try putting "qgif4.dll" in your app folder.
You can find it in. "\Qt\4.5.2\plugins\imageformats".

I've already tried, but it didnt help... thanks anyway

btw i realised that it isnt displaying .jpg too, only .png is viewable..

do you have QtSDK or self compiled Qt version? and create imageformats directory in your .exe dir and put right dlls (like qgif4.dll) in that directory

many, many thanks!! that worked - i needed to create the folder imageformats in my directory and put the dlls in there.

thank you

Now I have compiled the application static and I have the same problem again.
Neither adding imageformats folder nor adding the dlls to .exe directory solved...

Anyone an idea?
