DATA32* imlib_image_get_data ( void   ) 

A pointer to the image data.
Returns a pointer to the image data in the image set as the image for the current context. When you get this pointer it is assumed you are planning on writing to the data, thus once you do this the image can no longer be used for caching - in fact all images cached from this one will also be affected when you put the data back. If this matters it is suggested you clone the image first before playing with the image data. The image data is returned in the format of a DATA32 (32 bits) per pixel in a linear array ordered from the top left of the image to the bottom right going from left to right each line. Each pixel has the upper 8 bits as the alpha channel and the lower 8 bits are the blue channel - so a pixel's bits are ARGB (from most to least significant, 8 bits per channel). You must put the data back at some point.
