Hello,

i'm making a game using nokia ui api on series 40, and i have a problem while using DirectGraphics drawImage method with transformation (rotation, flipping).

I have a loop that constantly refresh the image on the screen by building it from 16*16 tiles, that are drawn with rotation, flipping etc...

When i navigate through my map, at some point the game crash, and i have this error message: "invalid heap pointer exception".
This occurs on the DirectGraphics drawImage method when i apply a transformation and when i'm near the limits of my map (the background consists of a map of 16*16 tiles that are drawn with flipping, rotation...).

Anybody encountered this problem?

Thanks.

hi,

we had the same problem! it seems that there is a bug or something in the DirectGraphics stuff.
as i know this error only happen when you draw a flipped or rotated image over the border of a backbuffer! set the clip one pixel smaler than the backbuffer and this did not happen!
this is what i know. but at the moment i have the same problem without doing any directgraphics stuff :(

any body out there who can help?

thanks
