I have the fugue icons, however, since the treeview on my software is too old fashioned, it only accepts either BMP or ICO. And it's very picky about transparency.
The image below shows a native bmp icon to the treeview, with the standard pinky background. And above it, the unsuccessful attempt of converting a png to bmp using Axilalis Icon Workshop.
Is there any software/website/place on earth that would convert it properly?
