Update read_pixels and its docstring
read_pixels returns 3D array of pixels.
When reading pixels we should also read the 'Alpha' values, so
instead of g.GL_RGB, we should use gl.GL_RGBA.
Fix test, have to compare with size + (4,)
Fix test, get rid of the alpha before testing
Update against PEP8
Flip the image before return
- In read_pixels, the result image is upside-down. Flip the image using `[::-1]`.
- Test for read_pixels
Flakification
No need to call `_vispy_warmup()`
Update flip with [::-1,:,:] instead of [::-1]
+ Fix typo
Fix typo
Add alpha toggle to `read_pixels`
Flatten namespace
Merge pull request #301 from mfkaptan/test-read-pixels
