funny, what if i wanted to make a circle or some other shape?

ETA, i think know the answer, i'm just seeing if im actually breaking any rules (and which ones) by doing what i hope to do.

I'm not clear on this, regarding the rules. Possibly in expert there would be no issue, but this might run up against the "no new shapes" part. To make a circle appear as such, you'd have to use the DPC bg color and copy it as your bg color.

that's what i was wondering...

I'm cropping off image area no different than a square or rectangular crop, the problem is that jpeg will force it to a rectangular shape and thus creating new area.. with png or gif this wouldn't be an issue.

Wouldn't it just be an 18% grey border?

As I said, I'M unclear. Perhaps one of the other SC with more knowledge can chime in.

It is legal, if not necessarily advisable ... essentially you are creating a non-rectangular border.

A long time ago I demonstrated a method which would create a (slightly) non-rectangular border under the Basic rules, and I have one actual submission ...

Note that even if you make your background/border an exact color match to the DPC page BG, there will still be a 1-pixel black rectangular border around the actual image.

Many moons ago I submitted this:



It was under the long-defunct Classic Editing rules, but (other than perhaps the shadow in the border) I can't see it being illegal under today's Advanced Rules.

Kirbic's example is the issue. While you could probably get an exact match for the gray, you'd still have the square border.
