your characters are not unicode compatible when typing directly. Put them in a unicode (utf-8) text editor file and then use the @ symbol. see http://www.imagemagick.org/Usage/text/#unicode this works for me with just Ä in the text file. convert -background lightblue -fill blue -pointsize 48 label:@...

I am not a Windows users, but there are some on the list who could help you convert my unix example above. But the windows information page does work and is at http://www.imagemagick.org/Usage/windows/

post an example image

see the ^ symbol for the geometry at http://www.imagemagick.org/script/comma ... p#geometry to resize to the smaller dimension. If on windows, see http://www.imagemagick.org/Usage/windows/

convert image -resize "100x100^" -gravity center -crop 100x100+0+0 +repage result

If this is not even close to what you want, then perhaps you need to upgrade your IM. I used 6.5.8-10 Q16 Mac OSX Tiger.

the IM team is working to convert my bcimage script into an IM function called -brightness-contrast. it is hoped to be available in IM 6.5.9.0

Here is some IM and unix code that will do the job. My example takes a 10x10 set of pixels from the top left of the rose image and displays it. I am not a Windows programmer so don't know how to convert to Windows. But see http://www.imagemagick.org/Usage/windows/ listArr=(`convert rose:[10x10+0+0] ...

How can I convert an image to NetPBM pgm (grayscale) plain/text format. If I do convert rose:[10x10+0+0] -colorspace gray -depth 8 rose10.pgm I get the binary pgm format (P5). I would like to get the plain pgm format (P2). Is this possible and if so, how to do that. I tried convert rose:[10x10+0+0] ...

try this convert logo: \ -background none -fill red -size 50x -pointsize 14 \ caption:"THIS IS TEST 1" -gravity northwest -geometry +10+10 -compose over -composite \ -background none -fill blue -size 50x -pointsize 14 \ caption:"THIS IS TEST 2" -gravity southeast -geometry +10+10...

use supersampling to get better quality from the pdf

convert -density 288 image.pdf -resize 25% -threshold XX% image.gif

add +repage after -crop and use -thumbnail rather than -resize so as to strip the headers and profiles, etc. to make the result smaller.

no way I know of to have IM format it for you to an array 40x30. if you want grayscale values rather than color use convert image -colorspace gray image.txt If your image is 40x30 pixels dimension, then you can convert to NetPBM (pgm) text/plain format and it will likely be in the 40x30 array with a...

try

convert source.jpg -background black -vignette 100x65000 result.png

Hi, I've been searching for good color segmentation algorithms and noone does not sutisfied me except of http://www.caip.rutgers.edu/~comanici/segm_images.html. Yes, I have been pushing for that open source code as well. Have you integrated this code for use with IM? If so, post it or send it to Ma...
