| Reference: | image_filter_transparency |
This directive allows you to disable image transparency in GIF and palette-based PNG to improve image resampling quality.
True color PNG alpha-channels are always preserved despite this setting.
Note: Grayscale PNG's are untested, but should be handled as truecolor PNGs.
