This is DBPro...

Can someone tell me anyone what is wrong with the attached bitmap? It is 150 x 150 and each sprite is 50 x 50. The images are not grabbed correctly with the following code.

Here is the test code:



If I run my code using animspr.bmp, from the examples folder, and change to a 4 x 4 animated sprite and change play sprite to 1 to 16 all is well. So I'm fairly convinced I've got soemthing wrong with the bitmap, but I just can't see it...

Thanks

Mike

it`s a 24 bit image according to winderz, try converting it to 32 or 16 bit depth, it could be the image depth is messing up the conversion witha wrong offset (I think there are 4 different formats for 24 bit, it might not recognise the one you are using).

Uh, I don't have any problem with it. It works here using
U6RC6, if that makes any difference.

ummm! yeah forgot to say, works here under U6 rc4 and 256mb Nvidia6200 card, like I said above, it could be your cards colour depth, but I am guessing, try saving it at another depth and seeing what happens, I have had problems with code portability where one PC runs at a different colour depth by default, for example my laptop and my desktop don`t agree on what colour value is white, so I have to write code that reads a white pixel off the screen and then uses the returned value as white (laptop is ATI gfx) otherwise the code fails to work correctly cos it can`t find the collision zones on a greyscale bitmap.
