Although I am not on the current release, in the past I have had the same problem. But seem to be able to cure it by adding export DISPLAY=:0 to my .profile file.

try my script magicwand at

http://www.fmwconcepts.com/imagemagick/index.html

convert imagename.suffix -threshold 100% outimage.suffix

The resulting image will be completely black.

use

convert imagename.suffix[widthxheight+xoffset+yoffset] -verbose info:

I tested this on my Mac version IM 6.3.6.4 and it works fine for me. I get a 24-bit black image with an 8-bit overlay channel that is fully transparent. The resulting image is RGBA 32-bits.

I believe that you can only do the processing for one output image at a time. But you can put all the steps inside one command. Here is a simple case assuming that the foregroundimg contains (alpha-channel) transparent areas: convert \( backgroundimg -resize 100x100! \) \( forgroundimg -resize 100x1...

Maxwell,

My testing was on IM 6.3.6.4. I have not checked on 6.3.7.x.

If you want to post me your test image somewhere and link it here, I will run it on my system and post the results.

You can try Anthony's flicker_cmp script that alternates the display of multiple images with a user specified time delay. http://www.imagemagick.org/Usage/scripts/flicker_cmp

You can try my binomial script. It does something like this with a binomial filter rather than a gaussian. You can either sharpen or blur and control the mixing with the original image. My laplacian script does something similar but uses the laplacian as the high pass filter. http://www.fmwconcepts....

I played with -adaptive-sharpen and found that it does nothing if you specify radiusxsigma as 0xanyvalue (e.g. 0x4), it does little if one specifies radius alone (e.g. 4), but does work if one specifies radiusxsigma as radius=3*sigma and a value for sigma (e.g. 12x4). With the other radiusxsigma fun...

You can blur the whole picture. Then draw the polyline on the original. Then make a binary mask from the polyline area. Then use -composite to overlay the one with the other using the mask to control which area shows from the original and which area shows from the blurred image. see: http://www.imag...

you can generally get a bold version of the specific font and specify that

Hello Anthony, My scripts were designed for command line use under the bash shell. I do not know about using them from PHP. I have no experience with the PHP API. Giving the full path and adding .sh may be needed for use with PHP. My script file itself does not have .sh appended, but that may be nee...

I just posted a new script, autotrim, to http://www.fmwconcepts.com/imagemagick/index.php which will automatically trim out any border pixels. But it will make the image smaller by the amount that is trimmed. If this is a small amount, just a few pixels out of 300 pixels, you can post-process the re...

Yes, you are right. My magicwand script only makes a binary outline image and does not allow the black area to be output as transparent. But your modification afterwards is what I would have done. Glad to hear it has worked out.
