Hi, magick.
It worked well. Thanks for that; I can't see the rest of the site from where I am. A friend emails me:
"Auto convert images in the grayscale colorspace to sRGB"
from the changelog. Is this standard now?

Greyscale too dark
I'm using ImageMagick-6.7.7-8-Q16-windows-static
The -colorspace Gray and -modulate 100,0 are both returning images that are much too dark.

Re: How to "Smart Sharpen," adaptive-sharpen not working
Isn't "smart sharpen" the same as edge sharpening? If so try this. INPUT.JPG ^ ( +clone -unsharp 0x2 ) ^ ( -clone 0 -separate -evaluate-sequence Mean -blur 0x2 -negate -edge 2 -level 0,50%% -blur 0x2 -level 0,50%% ) ^ -composite ^ OUTPUT.JPG The -separate -evaluate-sequence Mean gives you ...

Re: Alternative to modulate command to increase Saturation
Alternative to -modulate saturation:
convert INPUT.JPG ( +clone -colorspace Gray ) +swap -compose Blend -set option:compose:args 250 -composite OUTPUT.JPG
250 is a very heavy increase in saturation.

Re: Squaring images.
The whole point of the code was to retain the original canvas size for padding - white, in my example. The interesting part of a non-square image can be cut out, and the position of that image on the canvas can be varied independently. He also wanted to run the routine on a fairly large number of im...

Re: Squaring images.
The -gamma -1 blanks an canvas to white, -gamma 0 blanks a canvas to black. Why not run my code on an image to see if works. It does.
If the misuse of gamma is a worry to you then replace -gamma 0 with -fill BLACK -colorize 100% and -gamma -1 with -fill WHITE -colorize 100%

Nope. I might have misunderstood his intention, it's not entirely clear - to me - from the initial post, but this is where I meant my response to go.

Re: composite -compose screen @some % of overlay image?
It's worth noting that the parentheses require spaces on both sides of each character. Eg SPACE(SPACE... SPACE)SPACE. You could also try escaping the parentheses: \(... \). On Windows that would be ^(... ^).

Re: PNG Compression Level With -define...
Yup. I saw that the output file size was as expected; but it's difficult - for me - to check the integrity of the internal structure. Thanks again.

Possible Bug: ImageMagick-6.7.1-0-Q16-windows-dll on WinXP
Odd linear dropouts are appearing randomly in the upper half (as far as I can tell) of processed images. There isn't any particular command that seems to set them off and the same image processed again often doesn't show any sign of the problem. Here's an example: http://img811.imageshack.us/img811/...
