Description Frédéric Bron 2015-05-16 10:39:06 UTC 
On my camera, I see pixels with color #000000 or #FFFFFF blinking. This is very useful to assess the exposition. When I look at the pictures with gwenview, I miss this feature.

Reproducible: Always



Expected Results:  
when one of more of the 3 colors (red, green, blue) reaches 0 or 255, the pixel is viewed during 0.5 s as recorded and 0.5 s as pure white or pure black, that is, the color that is the most different. This can be determined as follows: calculate the average color (gray): g=(r+g+b)/3., if g<128, show #FFFFFF, if g>128, show #000000. We could also just show the complementary color (255-r, 255-g, 255-b).

My Gwenview version: 4.14.0 pre on KDE 4.14.6 on Fedora 20.

I would argue this is not a feature that should be in a simple image viewer, but rather a photo editor.
