[Gimp-user] Increasing pixel size
I have an old 7 mp image that I'm trying to increase to around 10MP. I've read it's best to increase by 10%, then unsharpen, and repeat process until you get to the desired result. I unsharpened with radius at 5, threshold 15, and amount .5. When I finished the process. I viewed the image at 100% and it was terrible. Any recommendations regarding the process or the unsharpened mask settings? Thanks. -- Byram (via www.gimpusers.com) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Re: [Gimp-user] Gimp-user Digest, Vol 94, Issue 25
Is that really a "must" ? It turns out I was missing variable declarations, but I have never provided initial values when declaring variables in a let block, and that doesn't seem to cause issues. I'll experiment.

I think that this line is not returning the number of layers as we're expecting. I tried using gimp-message to write the number of layers out to the console, but it generates another batch execution error.

You must provide an initial value when defining a variable in a let block. The simple solution is to add a 0 or -1 to the declarations for numeric variables and "" string variables.
