Hi,

I need to convert a multi-resolution ico to a png. When I invoke the command I get several output files, one for each resolution in the ico.

When I invoke the command I do get one file as output, but it seems to use the first resolution in the ico as input, which is the smallest one. With the files I'm using, it generates the 64x64 output based on 16x16 input.

How can I generate one png file, that's based on the 64x64 resolution bitmap that I know to exist inside the ico?

Thanks in advance.

I haven't any samples to test this, but you can probably use the [n] notation. eg ... ... where "4" is whichever number for the one you want. If you don't know which number that is, you can probably find it from "identify -verbose".

Code: Select all

convert image.ico[4] -thumbnail 64x64 -flatten image.png

Simply "identify file.ico" should work (without the "-verbose"). It'll list the dimensions for each "[n]".

Thanks a lot! That's exactly what I was looking for.
