Enlightenment CVS committal
Author : cedric
Project : e17
Module : libs/evas
Dir : e17/libs/evas/src/modules/loaders/png
Modified Files:
evas_image_load_png.c
Log Message:
* Make RGBA_IMAGE_HAS_ALPHA and RGBA_IMAGE_ALPHA_SPARSE part of
Image_Entry flag structure. This fix a bug with 16 bpp software engine.
* Change image loader module API to take any Image_Entry. Same goes
for evas_common_image_premul and evas_common_image_set_alpha_sparse.
* Use new eet API: eet_data_image_read_to_surface.
