a_Image_abort()

void a_Image_abort

Implement the abort method.

a_Image_close()

a_Image_get_dw()

void * a_Image_get_dw

(

DilloImage *

Image

)

Return the image renderer as a widget.

This is somewhat tricky, since simple casting leads to wrong (and hard to debug) results, because of multiple inheritance. This function can be used from C code, where only access to void* is possible.
