Re: the -size and -resize options are ignored if the output is a fax filetype

I am not sure why that does not work. It fails for me on IM 6.9.9.34 Q16 Max OSX. Try convert source.jpg -resize 1734 -rotate 90 -threshold 30% -compress FAX output.tif or convert source.jpg -resize 1734 -rotate 90 -threshold 30% -compress Group4 output.tif See https://www.imagemagick.org/script/com...

Please repost your links to your images to some other hosting provider or fix them so they work. Your links require login to download.

Re: Convert PSD to PNG keeping layer names.

ImageMagick does not understand layer names.

Re: Using ImageMagick on a network?

See Python Wand at http://docs.wand-py.org/en/0.4.4/. But I think it needs to be installed.

Also see the Web-Based ImageMagick at http://www.imagemagick.org/MagickStudio

Re: Color flatting with ImageMagick

That is the correct format. Yes, your system admin may set that limitation and you may not be able to relax it. Check with your system admin.

Re: Color Reduction for high quality RGBA4444 pngs

-colors produce no more than your requested number of colors but can be less due to the color quantization algorithm being uses. See

Re: -flatten won't work on PSD?

Post your PSD file to some free hosting service that does not change the format (or zip the file) and put the URL here. We need to see your file and what is in it to understand what is happening. Also what is your platform and exact IM version 7.0.1.x?

Slight change below from before.

I have cropped your color image for testing a small section. Input: http://www.fmwconcepts.com/misc_tests/sparse_color_fill/image_crop.png Note txt: outputs a line for each pixels of the form: 32,22: (0,0,0,0) #00000000 none 33,22: (7710,37008,65535,65535) #1E90FFFF DodgerBlue So the grep finds only...

Re: Color flatting with ImageMagick

Please provide output.png so we can test you command. I presume it is the colored image with white or transparency for the missing colors.

Re: posterize TIFF-files: how to prevent change of color-depth?

Only since you want 24-bit total color and want more than 256 colors. Otherwise, if less than 256 colors you would get 16-bits total (palette) without -depth 8 and 8-bits total (palette) with -depth 8.

Re: Color flatting with ImageMagick

Please always provide your IM version and platform when asking questions, since syntax may vary. Also it would be best to provide separate files, so people who might want to help can use it without having to crop it out of your combined image. What command did you try with sparse-color? Did you make...

Re: posterize TIFF-files: how to prevent change of color-depth?

ImageMagick default depths are defined by the Q level of the install. If using Q16 (default), then if the format supports 16-bit depths, then it will be 16, but if not then you will get 8-bit depths. To enforce 8-bit depths use -depth 8 or use a Q8 install.

Re: Download Tab - The UPLOAD page not working

With that information, I can confirm that it does not work as you say and as the instructions say:

"Click on any image to view"

I get your same error message.

Now that it is confirmed, the ImageMagick developers will have to check it out.

Re: log-scale histogram

It turns out, I already had a argument -l to make a log plot of the counts in the histogram in the plot script.

Code: Select all

plot -p histogram -l -m filled -f 1 -w 256 -h 256 -t 20 -d 2 -b 0 -g front rose: rose_hist_log.png
