base png test file
SUMMARY
I have a script which converts a png file to another png file and a jpg file.
To convert I use imagemagick's convert command. The resulting jpg file is
alright but the png file has washed out light colours.
The command that I use is this
convert test.png -background white -alpha remove test-converted.png
The resulting file is properly displayed in firefox, google chrome, GIMP,
krita, Okular, Showfoto etc. Only gwenview shows the colour in the image as
washed out.
My monitor is calibrated and gwenview has perceptual rendering intent and also
Apply only embedded colour profile enabled.
STEPS TO REPRODUCE
1. Open the attached png file
2. convert it using the imagemagick command mentioned above to another png
file
3. then open it in gwenview
OBSERVED RESULT
Colours are washed out
EXPECTED RESULT
Colours should appear how they are intended in the image
I am also attaching a screenshot showing how it looks on my screen
