Edit palette - indexes selection, color and transparency

Post by user0 »

XnViewMP 1.4.4 64bit
Windows11 (22H2), display resolution 3840x2160, win scaling 150%

Edit palette dialog
slightly improve functionality

Suggestion A - alpha channel
  • add functionality to set 0-255 alpha channel value
  • add visualization of alpha value on index map (eg same as in TweakPNG)
  • add functionality to select and modify multiple indexes
    eg select multiple indexes via ctrl/shift+mouse/arrows and press enter to edit colors or del to delete indexes
    • set color/alpha
    • delete index
  • add control to modify 'Edit Index' action (doubleclick), it can be:
    • checkbox - 'Edit Alpha channel' OR
    • radio button - to switch between RGB and Alpha

Suggestion B - unique colors
  • add functionlity to see unique colors (eg via tabs: Indexes, Unique colors), so it is possible:
    - to see which colors are unique
    - to modify them affecting all related indexes

Suggestion C - sort palette
  • add functionlity to sort colors in palette (eg sorting in Aseprite)
