Glad it works on linux. The second rotate, -rotate 45 is the one I meant. That's why I added -append as part of the title to this report.
I've tried it again. Still hanging. It seems to be related to size of input image. 800x600 px works fine; 4000x3000 px doesn't.

Possible Bug -append/-rotate IM 6.7.1-0 Q16 on WinXP
This command having started, hangs absolutely dead. It works okay without -rotate.
convert IN.JPG ^
( +clone -rotate -22.5 ) ^
-compose Src -composite ^
( +clone -flip ) ^
-append ^
-rotate 45 ^
OUT.JPG
( +distort SRT 45 works as expected.)
Thanks.

Banding in Composited Gradients
Hi, all. A question regarding "banding" when compositing gradients. I have some (approx. 800) full-size crops (jpegs) of cloud formations. I need to apply a gradient similar to a weak, rectangular vignette to perform what you might call the digital equivalent of edge-burning in order to de...

Re: Lab Implementation
Standard deviations and their implications aren't really my bag but I get the general drift - the lower the number the better. My comparison was by eyeballing: GIMP and original ImageMagick http://img293.imageshack.us/img293/9056/smallimg2641oldlab.jpg New ImageMagick http://img340.imageshack.us/img...

Re: Lab Implementation
Well, you've got me there. I've no access to PhotoShop (or GIMP), just their (converted) output files; but virtually everything to do with running anything on Windows has 6500K on it so you're likely right. My monitor calibration software says D65 with gamma 2.20.

Re: Lab Implementation
Okay. I tested it, and you won't be surprised - it works!
Just for curiosity's sake; why are the L channel separations in PhotoShop, GIMP, etc. so much lighter in tone?
Anyway, thanks a lot - very speedy service. Cheers.

Lab Implementation
Hi. Like to draw your attention to a possible bug (or at least an inconsistency of implementation) in Lab when translating between colour spaces. Fuller explanation here: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=16223&p=58811&sid=01cb5c3d2350bef7ac5fcf1cc96cd641&am...

Re: Lab Implementation
Hey, fmw42 . Thanks for the response. Yup, I understand the difference between Lab and RGB ; but the result of flipping modes should be barely perceptible - if at all - to the human eye. Photoshop manages translations Lab/RGB - RGB/Lab well enough so I expected ImageMagick to be similar - swapping t...

Lab Implementation
Hi all. I've just been attempting to sharpen images using the L channel of Lab. This should be straightforward but the overall brightness/gamma is substantially altered. An example: Running -colorspace Lab -channel R -unsharp "0x0.8" +channel on http://img179.imageshack.us/img179/3820/img2...
