I am not sure about the use of eps files, but you can try that with my newly posted autotrim script which you can find at http://www.fmwconcepts.com/imagemagick/index.php. If it does not work with the eps file, try converting the eps to some other format before using the script and then converting b...

You can try one of 3 things: 1) use -blur to blur the edge slightly with the transparent background 2) magnify your original image by 2 or 4 in each direction, then extract the edge result, then minimize the result back to your original size (use -filter lanczos -resize) 3) modify the magicwand scri...

Hello, After upgrading to IM 6.3.7.1 (special Mac OS 10.4 Tiger build without X11), I am finding that one of my scripts to perform NASA's retinex processing no longer produces the same good results as it did in IM 6.3.6.4. Here is the original image http://www.fmwconcepts.com/misc_tests/retinex/zeld...

OK. Thanks for the explanation.

Not to look a gift horse in the mouth, but how was it that until recently you were able to build Mac OS 10.4 Tiger binaries with X11 support and now you cannot? Is it not possible to install X11 on this older PowerPC? It should be available form Apple or elsewhere. (It is unfortunate for the Mac com...

Thanks. It mostly works. But I cannot display an image. I get messages about usage: display logo: Version: ImageMagick 6.3.7 11/19/07 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2007 ImageMagick Studio LLC Usage: display [options ...] file [ [options ...] file ...] and much more bel...

see my magicwand script at http://www.fmwconcepts.com/imagemagick/index.html The basic command is: # make interior transparent and outside black convert $infile -fuzz $threshold% -fill none -draw "matte $coords floodfill" \ -fill black -colorize 100% $outfile $threshold% is typically 10% $...

Here is a bash script that will determine if your box is turned. A perfectly rectangular orientation will give a result of zero or black. Any distortion (rotation) will produce a larger result. Your image gives a value of about 15%. The script processes the image to binary format (white for box and ...

Tough problem! Even if you could crop a triangle, how do you know where to crop it and at what angle, if you don't know whether the box is turned or not? Once you find out if it is turned or not, then what are you going to do with that information? What is your ultimate goal? What average graylevel ...

Are all your images similar to the astronomical example you have presented? I ran this example using my space script and was able to do a fairly decent job of removal of the uneven illumination. The space algorithm does not care where the glare is in the image. It just tries to even it out using a s...

thanks

I now see that IM v6.3.7 is out, but still no build for Mac OS 10.4.x Tiger. Would it be possible to make a binary build for Tiger along with the Mac OS 10.5.x Leopard when new builds are made for all operating systems? Thanks.

I am not quite sure what you are trying to do, but IM display function in command line mode has the ability to rotate, crop, and other transformations. If you want to look at multiple images, you can display them alternately with a delay in a script by Anthony Thyssen called flicker_cmp (it is a bli...

Try this and go from there. This works. Learned it from Anthony Thyssen Recoloring transparent areas # create test image (red square surrounded by black) convert -size 100x100 xc:red -bordercolor black -border 50 tmp.png # to make red transparent convert tmp.png -transparent red tmp1.png # to make t...

Documentation for -threshold on http://www.imagemagick.org/script/command-line-options.php#threshold says: Create an image such that any pixel sample that is equal to, or exceeds the threshold, is reassigned the maximum intensity otherwise the minimum intensity. To generate an all-black or all-white...
