transparent and .ico file

Sorry if this is out of topic question.

Why I can not save a .ico file with a transparent background?
I'm using IrfanView

Thanks

No body love me :-(

 

No, it's just that this isn't a Irfanview newsgroup.

I have no problems saving icons with trans bg's in Irfanview.

 

Sorry if this is out of topic question.

then what wrong am I doing that I can not save it as transparent?

 

You can easily do this directly from Photoshop with my .ico file format plugin:

Thanks allot, but still dose not save it as a transparent, I can still
see the background.
Am I doing something wrong here?

 

The README has more details. ICO files have a 1-bit transparency mask
and may also have an 8-bit alpha channel (32-bit "XP-style" icons).

The plugin derives the 1-bit transparency mask in 3 possible ways:
- from layer transparency when creating an RGB+alpha (32-bit) icon
- from transparent palette index when creating an Indexed mode icon
- from an alpha channel (black=opaque, white=transparent)

Also try opening someone else's favicon.ico with transparency and
you'll see the alpha channel representing the mask.

That was a good idea.
I do not believe I did not think of that.
