icon dimensions

[Zohran]

if i open a 32x32 icon with a icon editor i see the same icon of different pixels. how shall i retrieve the dimensions of them all..

because

with

$hImage = _GDIPlus_ImageLoadFromFile("example.ico")

_GDIPlus_ImageGetWidth($hImage) and _GDIPlus_ImageGetHeight($hImage) we get only one size of icon not dimensions of other icons present in the icon file
