# For smooth rendering on high-DPI displays, the standard three app icon sizes
|
||
|
|
# (16x16, 32x32 and 48x48) have to be scaled to the four Windows DPI settings
|
||
|
|
# as in the table below:
|
||
|
|
|
||
|
|
# Small Regular Tiles
|
||
|
|
# 96 DPI (100%) 16x16 32x32 48x48
|
||
|
|
# 120 DPI (125%) 20x20 40x40 60x60
|
||
|
|
# 144 DPI (150%) 24x24 48x48 72x72
|
||
|
|
# 196 DPI (200%) 32x32 64x64 96x96
|
||
|
|
|
||
|
|
# Also, there should also be an extra large 256x256 icon and some low colour
|
||
|
|
# 8-bit and 4-bit variants, which are still used in Remote Desktop.
|
||
|
|
|
||
|
|
# Note: Windows Vista has a bug in its icon scaling that makes no sense.
|
||
|
|
# Instead of following the DPI setting, small icons are always a bit larger
|
||
|
|
# than they should be at 22x22, 26x26 and 36x36 for 120, 144 and 196 DPI. This
|
||
|
|
# script doesn't generate icons with those sizes, since computers with Vista
|
||
|
|
# and a high-DPI display are probably fairly rare these days.
