IrfanView: Saving ICO with transparency
I think it's just a case of function overkill. It used to
have only a checkbox to save transparency. The main window color checkbox seems to be an option to select the background color without needing to go through the click-on-the-image step to select the transparent color. It doesn't really make much sense, though, because icons sometimes don't have an unambiguous "background" color. So, check "Save Transparency" to get a transparent color. Check the "main window color" checkbox if you think it's exhausting to have to click in the window to choose a transparent color, and you don't mind risking that IrfanView will pick the wrong color. If you don't check it, IrfanView will present the window where you can click on the color you want transparent. Try it out. It'll be obvious once you do it. | But I'm unsure how the other 3 options would be used? What is the 'main | window colour'? IOW, how do you set up the transparency colour in each of | the other 3 cases: | | #2. Both checkmarked | #3. Neither | #4. 'Use main window...' checkmark greyed. | | -- | Terry, East Grinstead, UK |

IrfanView: Saving ICO with transparency
Thanks. But I had tried that "main window color" checkbox and there was no
transparency in the result. -- Terry, East Grinstead, UK "Mayayana" wrote: I think it's just a case of function overkill. It used to have only a checkbox to save transparency.

"Terry Pinnell" wrote in message news | Thanks. But I had tried that "main window color" checkbox and there was no | transparency in the result. | I see you're right. That's weird. From the help: "If you activate the option Use main window color for transparency, the current window color (Properties-Viewing) will be automatically set as transparent color." I made the error of assuming the function made sense and that therefore the checkbox text must be worded badly. But it actually means what it says. It sets the IV window background color as the transparent color! I tried it and it works. In my case I set the IV background gray, to match my default window frame color. I can't imagine what Mr. Skildjan was thinking. |

IrfanView: Saving ICO with transparency
| Yes, unless i hear to the contrary I think that option is unlikely to be
| useful! I'll ask Irfan about it. | I seem to be missing at least 2 posts in this thread. I don't know why. Talking about "window color" is confusing, but it also applies, in my tests. If I use an image with transparency and resave as another image then checking that box will save the same transparent color. If I save a solid image then it actually does set the transparent color to be whatever the IV window color is, which makes no sense. And how often would a transparent image be resaved? If I edit the image I won't be doing that in IV. So the option would only apply when saving a GIF to ICO, GIF to PNG, PNG to GIF, etc. I don't think I've ever done any of those operations. ... I'm guessing that that pointless and confusing extra option in v. 4.35, which was not present in v. 4.33, will disappear in a later release. | | Here's his helpful reply: | | --- Start paste --- | Main window color: start IrfanView without the image and see the window | color. | | == "Use main window color" option makes sense only IF the loaded | image was already transparent, so you can use the same color again | ... without an extra click. | | If you have a JPG image, which is never transparent, uncheck that | option, so you will see a preview window and you have to click and | choose the new transparent color. | --- End paste --- | | -- | Terry, East Grinstead, UK |

That *you* don't do such things doesn't mean, /nobody/ does. Editing existing icons to create new ones can perfectly be done in IrfanView with Paint plugin, for instance. And when creating a whole bunch of them, the removed tedious extra-step to select the transparent color on saving is welcome.
