Setting up pixel array data for Evas Image Object
سؤال
This question is about use of evas_object_image_data_set
function.
Say, I have some pixel array in RGBA format. I make a transformation on it to become ARGB, suitable for Evas Image Object.
Next thing I create a window with elm_win_add
.
Then I create image object with evas_object_image_add(evas_object_evas_get(window))
.
After that I call to evas_object_image_fill_set
, then evas_object_image_size_set
.
Then I call evas_object_image_data_set
and finally I call evas_object_image_data_update_add
with approriate region for my image.
After all this done I see nothing but black box. Am I doing something wrong?
P.S.: using efl version 1.7.7
