# The script helps to automate fixing issue "libpng warning: iCCP: known incorrect sRGB profile".
|
|
# Main idea: https://stackoverflow.com/questions/22745076/libpng-warning-iccp-known-incorrect-srgb-profile
|
|
|
|
# Use "pngcrush" to remove the incorrect sRGB profile from the png file
|
|
# Link: http://pmt.sourceforge.net/pngcrush/
|
|
|
|
# -ow will overwrite the input file
|
|
# -rem allb will remove all ancillary chunks except tRNS and gAMA
|
|
# -reduce does lossless color-type or bit-depth reduction
|
|
|
|
#In the console output you should see "Removed the sRGB chunk.", and possibly more messages about chunk removals.
|
|
#You will end up with a smaller, optimized png file. As the command will overwrite the original file, make
|
|
#sure to create a backup or use version control.
|
|
|
|
# IMPORTANT!!! Run script inside 'scripts' directory.
|
|
|
|
# usage:
|
|
# $ ./fix_png.sh
|
|
