Hidden 64*64 icon rule...

[Dr Super Good]

As I said, no icon with size other than 64x64 pixels will be accepted.

According to the moderator Murlocologist there is a 64*64 resolution limit rule for icons. If such a rule does exist then why is it not on the Icon Submission Rules page? I can imagine this confusing many users...

Should such a rule even exist? As long as the icon is at least a multiple 64*64 pixels it can stylistically blend in with existing WC3 icons. One could make a 128*128 icon using upscaled WC3 boarders and it should blend in very well with other lower resolution icons. In theory 96*96 icons may even work but the upscaled boarder might appear slightly different from standard boarders due to rounding. Anything above 128*128 would be wasteful and even reduce image quality due to aliasing occurring as WC3 UI elements are subject to bilinear filtering with mipmaps not being used.

It's not in the rules, but who ever talked about such high resolution icons other than mr DSG himself. All icons by Blizzard are 64x64 aren't they? Isn't that the "supported" and "expected" way to handle this?

Isn't that the "supported" and "expected" way to handle this?

Warcraft III supports icons of any size. Icons that are too high a resolution suffer from aliasing due to the UI not using mipmaps.

The reason 64*64 icons were chosen was that people had on average lower resolution displays back when Warcraft III was made than today so more detail could not be displayed. Seeing how enormous WC3 icons are in game means that they would benefit from being higher resolution than 64*64 pixels such as 128*128 pixels since it will allow higher frequency information to be displayed. Also since the map size limit has been raised it is semi-viable to have 20-40kb icons now.

In any case if the rule exists it should be mentioned in the rules section to prevent people wasting their time making something that will never be approved.

Did this actually happen? Cause I think the system prevents icons with non-64x64 dimensions:

                    if ($parser->data->width != 64 || $parser->data->height != 64)
                    {
                        $errors['progressErrors'][$iconKey] = 'The uploaded icon must be exactly 64x64.';
                    }
