With the usual Windows tools I use ("Explorer" and "Photo Viewer"), Altered.TIF looks fine. However, "Microsoft Office Picture Manager 2006" shows Altered.TIF as green. There is a "color enhancement" facility that lets me click on an area in the picture that s...

What do you think it is doing wrong?

It's also helpful if you state your platform and IM version.

I have reported this on the bugs forum: viewtopic.php?f=3&t=22720

The current version of IM for Windows, 6.8.2-0, seems to be removing transparency. "%IMG682%convert" -size 100x100 xc:none -fill Red -draw "rectangle 20,20 80,80" t.png "%IMG682%convert" t.png t2.png t2.png has black where t.png wa transparent. See also http://www.image...

I can reproduce the problem on Windows 7 in 6.8.2-0. It did not occur in v 6.8.1-10. The problem is independant of "+append". It seems that IM 6.8.2 is simply removing transparency: "%IMG682%convert" -size 100x100 xc:none -fill Red -draw "rectangle 20,20 80,80" t.png &q...

Update: we don't need "-colorspace Gray", so the command simplifies to:

I don't think there is a way to guarantee a particular palette order. However, it seems that this does what you want (in IM v 6.7.9 on Windows7): "%IMG%convert" palette.bmp -set colorspace RGB -colorspace Gray -type Palette p.bmp "identify -verbose" shows the palette in p.bmp, an...

Any ideas on how to make this work on all files in one directory and create a directory of the cropped images within it?

Instead of out\%2, just put whatever directory and filename you want. If you are putting this in a Windows batch file, you need to double up the % signs. If you are typing at the command line, don't double them. I showed it as one command. If you want it as two commands, here they are: "%IMG%co...

Oh. Ah. Um. A script is a text file that contains commands. How you create one depends on what type of computer you are using -- in particular the operating system. This isn't a scripting forum, and I wouldn't attempt to explain it. There many guides on the net. Likewise, this isn't a camera forum. ...

The camera exposure varies, according to the size of the receipt. It's better to use manual control, where the camera has it, so backgrounds and foregrounds are consistent. Of course, a scanner would be even better. The "black" background has light smudges, needing some heavy manipulation ...

v6.8.0-9 was also broken.

Confirmed, on Windows 7. Example of 6.8.1-10, then 6.7.9-6: D:\web\im> D:\web\im>"%IMG681%convert" -verbose j.pdf jj.jpg [ghostscript library] Files (x86)/gs/gs8.71/bin/gswin32c.exe" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dEPSCrop -dAlignToPixels=0 -dGr...

What is "-colorspace RGB" doing in your commands? When I use that, I get your (bad) result. When I omit it, I get what I think is the correct result. You don't need to change the colorspace, and I think you shouldn't. (As an aside, I would rather like to be able to specify an image and map...

Blurring will find the corners of a white line on black background, because there is a greater density of white at a corner. For example, if we draw the white outline of a square on a black background, and then blur it, the corners are lighter than the edges. "%IMG%convert" ^ -size 100x100...
