nconvert from JPG to ico

[peter733]

I use :

nconvert.exe -quiet -out ico -32bits -resize 256 256 inputfile

the resulting ico looks ok but when used a a folder thumbnail it appears as a smaller thumbnail with black border

is it ?

[peter733]

it seems I need to create a ico file that has both 256x256 and 48x48 in order for the folder thumbnail to work. but with nconvert i can only create one: either 256x256 or 48x48 but not both. is this a limitation of the current nconvert ?

thank you,
peter

Currently you can't create a multi resolution ico file
