IM is exact same version.

thread limit doesn't seem to change sys time at all.

So, I set up a new computer, same specs as an old one, but it's lagging a lot. I ran a few benchmarks, and you can see here: system 1# time convert rose: -resize 5000x5000 -bench 5 /tmp/rose.png Performance: 5i 0.221729ips 26.050u 0:22.549 real 0m22.554s user 0m25.795s sys 0m0.262s system 2#time con...

Hmm. The more I look at it, the more I need an improved trim.. it doesn't seem to detect the edge well enough.

Well, here's what I've done so far with my pseudo code.. circle to square stretch... http://img403.imageshack.us/img403/4894/77400526.png somewhat useful, though you can clearly see the pixel jitteryness. I was using -trim .. which doesn't seem to like 1 pixel wide images.. otherwise pretty simple. ...

Interesting .. a search for that yields map projection software.. which might be just what I need..

I wrote this pseudo code that shows what I'm thinking I want done:


split image into horizontal lines

foreach line {
autocrop line (based on transparency)
scale line to width of original image
}
join lines

Hmm. Well, that's not working too well... it's not providing near enough of an exact edge... it just seems to zoom in on the image a bit convert circle.jpg -matte -virtual-pixel black -distort Polynomial '1.5 285,6 0,6 277,6 0,6 270,7 0,7 263,7 0,7 255,13 0,13 246,16 0,16 239,17 0,17 229,20 0,20 220...

So, I'm trying to distort a shape, say a triangle or circle or any shape really into a square or rectangle... sorta like a rolling pin flattening dough into a square pizza. (and for the moment, I'm only interested in stretching the pixels horizontally.) For the circle, the top and bottom of the circ...

Wow, this is definitely more complicated than I thought. Sorry I didn't give more specific examples.. This is a general problem for me, in that I have a number operations and different image types where I need to expand the canvas size, and I was certainly hoping there was an easier way to do it, wi...

for an example: (with 3 images)



overlap areas are highlighted, but really they should end up blending in better.

Yes, the two images are the same size, so with the offset, part of the overlayed image is getting cropped off. -layers merge does not expand the canvas in this case. I guess it sorta makes sense that only the base image size remains, because it's getting blended.. but, I guess I was looking for an e...

Ok, I think I had the images 1 and 2 reversed.. but.. this doesn't solve the problem.

How do I get the canvas to expand to include both images?

I'm blending two images together like so: composite -blend 50x50 -geometry +100+0 image1.jpg image2.jpg +repage image-out.jpg The output image only comes out the size of image1.jpg.... I'd like it to not clip off the side of image2.jpg in the final image. Is there an easy way to do that? I've seen t...

Maybe if it's composted from random dots.. then some glow is added.. it might get close..

So, I had this crazy effect idea that would turn a line drawing into Christmas lights. (think coloring book line drawing) I guess the simplest way would be compose it with an image full of lights... not sure how that would would look.. But, I'm looking for a better way. If I had the draw command for...
