Description
Grayscale mode for image is the Magic Wand, when client is behind the poor internet bandwidth.
The grayscale images up to 2-3 times smaller, but make no discomfort when work with 90% of tasks, except graphics.
Switch the guacd <> client color and quality mode dynamic at protocol level will be the super improvement, so client able to analyze bandwidth switch the best performance mode.
guacd already does this. Prior to sending graphical updates, those updates are analyzed for content and frequency in order to determine what is likely to be best. Updates which appear photographic and update frequently enough are sent using lossy compression with quality varying based on analysis of client performance (
GUACAMOLE-632). Updates which do not appear to be photographic are sent using lossless compression, with a 256-color palette automatically used if the image uses 256 colors or less. This will be the case for grayscale images by definition.
