I just tried it on the newest version and measured the performance against a version not compiled with OpenCL. Both finished, but they took the exact same amount of time 1Min32Sec. I'm hoping this suggest it's not using the GPU for some reason.

I'll try with the newest version, but shouldn't it not fail halfway? Mine didn't go anywhere as far as I can tell, but it doesn't seem like failing half way is the intended behavior.

I was wondering if you had a chance to try this again?

If it helps, I'm running a GTX 1080 with the 368.39 drivers and CUDA 8.0.27

Hello, I compiled ImageMagick 7.0.2-2Q16 on Windows 10, Static Multi-threaded runtimes, 64 bit distribution, HDRI, OpenMP, OpenCL, Q16 and Studio 2015. Specifically, I wanted OpenCL support. I tried a simple resize of a 300 MB image from NASA and am getting the error: Assertion Failed: pixels ...

It's overlaying this over the image:

Wow, you guys are awesome, thanks for the discussion and all the help on this. I just tried it out and it worked very well on everything but the left edge on the first image I uploaded. I've noticed that I've had very good luck with all the documents except that one. I had to use the virtual-pixel ...

Thank you, here are samples of 2 of the images: http://i.imgur.com/90Sng5H.jpg http://i.imgur.com/KcL6d5D.jpg I have many more of them and would like to align them to eachother. I'll take a look at the link you sent. I also noticed the limereg project. I compiled it, but there are no instructions on ...

I have a few scanned forms that are cropped differently, a little rotated, and feature other scanning issues. I'd like to make sure that they're all aligned correctly given one reference image. They should be the same dimensions, and the boxes should overlay one on top of the other so when doing ...

I forgot the % for the deskew, that fixed it.

I found this to work well: convert -density 1200 -deskew 40 20.pdf[0] -deskew 40 -resize 25% +repage t.png; convert t.png -crop \ `convert t.png -virtual-pixel edge -blur 0x15 -fuzz 20% \ -trim -format '%wx%h%O' info:` +repage 20.png Is there a way to properly work the deskew into here? Most of my ...

So, would it be something like this: convert c:\20.png -fuzz 99% -fill white -draw "color 0,0 flood
fill" -trim +repage c:\20.out.png?

Thank you, I'll take a look at doing that. Isn't that what fuzz is for though?

Hello, I'm having an issue with trim. I have a set of scanned documents I'm trying to automatically process, but trim doesn't seem to be removing whitespaces from them. I've tried with the borders and with fuzz, but no luck. Any help would be much appreciated.
