Evas recently got YV12 support for images, which is in the GL engine is

I guess this is less of an evas question and more of an OpenGL one, and

Hi,
There seems to be a problem with the GL engine given an evas image in
YUV colorspace when setting data via evas_object_image_data_set() if the
stride of the data does not equal the image's width. (By this I mean
that where data is treated as an array of pointers, given any two

I'm not sure either. When I discovered the bug last night I asked

I would definitely love to see subpixel resolution (for scaling and
positioning of objects, particularly). Is this on the radar? Or is it
a complete pipe dream?

So there seems to be two separate problems with BGRA32 here.
Just to follow up, I saw raster had committed a few related changes
I've encountered another bug. This one exists with ARGB32 but not
BGRA32.
If the row stride given in the info struct (dest_buffer_row_bytes) is
not equal to the output width * 4, nothing ends up getting rendered to
the canvas (it is completely empty).
See attached test case.

Hi all,
I've been quite out of the loop for a while (new job, relocated), so I
haven't been following evas changes very well. I've just upgraded from

canvas with respect to transparent (or rather I guess undefined)
backgrounds.

is the optimal way to do it. Nevertheless, the code is trivial enough
