Errors in ICO when saving from GIF with transparency

Hi there,
I experience problems with gifs with transparency when using 'Save as' -> .ico-File.
It almost always has a vertical line at the right side of the picture (ico-file), which was not there before in the gif-file.
Anyone experience the same?
Can anyone help?
I am using XnView for windows, version 1.82.4 (Mar 3 2006) and Libformat Version 4.57 with WinXP and Windows Service Pack 2.
Thanks for any help!!
Nick

Hello !
• From GIF or another format, there is a problem with *.ico from ages about the transparency…
- XnView doesn't display it for this format, the BG is always either
black, or
black, or
black…
- I tested to save a GIF 256 colours with a transparent BG into *.ico.
- The transparency is not rendered, strangely, the BG becomes all grey and the details are lost,
but I don't get the vertical bar you say…

Kind regards,
Claude

So it is not possible?

Hi,
thanks for your reply. So are you actually saying, that there is no way to save an ico-File with transparency wtih XnView?
No workaround? What else could it do?

Hello !
• You may set the transparency for an icon *.ico max. 8 BPP (256 colours).
- Use the "Image" menu “Edit palette”.
- Set the BG colour as the transparency (tick the box after you have selected the BG) >> OK >> Save.
- On the spot, that works, but when you close ¦ display again that icon, the BG is black…
- However, the transparency is there, you can see it using other viewers…
- IMHO, it's always better to convert a BMP than a GIF to make icons…

Nick, some information that might help solve the problem can be found in this thread:
Windows Ico shows pink where transparency expected.
