Icon size bigger than 256x256 pixels?

[Velociraptor5]

Does anyone know, if it is possible to create an icon bigger than 256 pixels?
And if it is possible, so what tool is suitable for it.

Now, I am able to create the icon where the size is 256x256 in 256 colours in "Image2Icon". Until recently, I thought, It's maximum size, but then I found out, the game "Cyber Games" uses the icon where the size is 320x146 pixels (see picture).

I think, that the tool "Iconian" should be able to create the icon bigger than 256x256, but unfortunately I am not able to confirm it, because this tool doesn't work correctly or doesn't work at all under "Classic Workbench" (mainly the big icon sizes). It's a known bug.

So, any idea, what tool can do it?

Thanks

I should have a program that converts an Iff brush to an icon, but it may take a while to dig it out - this was 30 years ago I wrote it. There should be also come paint programs that can save a brush as icon, so probably ppaint can do that.

You can try this one : http://aminet.net/package/gfx/conv/IFF2Icon

I have tested PPaint. now I already don't remember exactly, but I wasn't able to create icon bigger than 96x96 (or 128x128?) there.

Thanks for the tip. I'll look at it.
But yet one sub-question... All what I would like to convert to an icon, I have in PNG format. Does here exist some tool for converting from PNG to IFF? (If the tool "IFF2Icon" can't work with PNG)

Try this:

If you manage PNG icons, you can get an icon by renaming .png to .info

You have various choice to convert the png to iff.
You can prepare almost everything on your PC first. GraphX2 may help you : http://grafx2.chez.com/
Be careful of how many colours has your original image for a good result.

I know, that I can get an icon by renaming .png to .info. But these icons may be only 256x256 and reading of them is slower than reading of "classic" icon, if you have lot of them (minimally what I know in Classic Workbench 3.1).

Also thanks for the tip.
I'll be playing with it.

Icons with a size larger than 256x256 (93x93 for NewIcons) are not supported by icon.library v44+.

For old planar icons the values of Width and Height are words in the Gadget and Image structure, and therefore it may still work to use larger images, but could have strange side effects and is not recommended.

For ColorIcons the Width and Height are subtracted by 1 and stored as bytes in the FACE chunk, so they are limited to 256.

I found the "IFFtoIcon" program, I am attaching it. Best run from the Shell, with the name of the Iff brush as argument. If I recall, it places the icon in RAM:


If I recall you can also run it from the workbench. Then click the brush first (single), then double-click the IffToIcon program.

I do not see such a restriction in the system icon.library - the width and height are UWORDs. Whether that is useful is of course another issue.

Yes, as I said, old icons can still store 16 bit values in the Gadget and Image structure, ColorIcons only bytes.

At least my library will probably reject images with a Width or Height of more than 256 and you may get the internal default icons instead.

Thanks for it.
I'll try it.
