Managing memory for a ton of pictures

My gimp version hasnt these options.
But it looks like this is a support nightmare anyway so this is may be not the way to go.

ImageMagick (a CLI tool, has an official portable version that doesn't need to be installed) seems to support converting to .DDS format with "dxt1" or "dxt5" profiles.

The below was taken from this link here: https://legacy.imagemagick.org/discours ... 99#p167668

From the format page at https://imagemagick.org/script/formats.php

DDS RW Microsoft Direct Draw Surface Use -define to specify the compression (e.g. -define dds:compression={dxt1, dxt5, none}). Other defines include dds:cluster-fit={true,false}, dds:weight-by-alpha={true,false}, dds:fast-mipmaps={true,false}, and use dds:mipmaps to set the number of mipmaps (use fromlist to use the image list).

Have you tried

Code: Select all

convert  'input_file.xxx' -define dd:mipmaps=1 -define dds:compression=dxt1 'DDS:output_file.dds'

There's some notes on the differences between dxt1 and dxt5 in the Löve wiki, scroll down to "Compressed Formats": https://love2d.org/wiki/PixelFormat
