getOriginalSize() crashes when fed a .gif

[magicaxis]

Hiya.

I'm making several objects with images for textures. pngs, jpgs, bmps, they all work fine. but when a gif goes through my code it crashes out. it says the error is here:

Code: Select all

        picture->setScale(core::vector3df(
                1,
                picture->getMaterial(0).getTexture(0)->getOriginalSize().Height/scaledown,
                picture->getMaterial(0).getTexture(0)->getOriginalSize().Width/scaledown));

Specifically it says the error is in the last line of that code.

Does anyone know why .gifs would cause such a ruckus?

What can I do to allow a gif to work? Bear in mind that these .gifs are NOT animated.

I also have no idea. Could you give us more information. For example what kind of type is picture? Or post a complete example to reproduce it. And add the gif that fails.

I have tried several gifs, and they all crash the program at that place. Is there anything special about gifs im unaware of?

Well, tell us at least what picture is in your case. IGUIImage has no scale - is this a billboardscenode? Or some own class? Also which compiler, which OS and 32-bit or 64-bit?

edit: OK, forget it - I managed to reproduce it. Have to check it in the evening.

oh sorry windows 7, picture is an IMeshScene Node*, and it is within the class "Pictureframe".

Ehm - check for NULL, the crash is not the function but because the image never loaded. The reason being that we have no support for gif-loading in Irrlicht. So either convert your images to another image-format ... or write a gif-loader.

Aah, i was afraid of that. Thank you
