I still get a transparent CMYK tiff as the result of my commands above. Perhaps you are missing the one transparent color in the histogram of the result. Yes, I see one transparent color. But when compare with RGB case with your original script, Alpha: graya(255,0) #FFFFFF00 Colors: 116 Histogram: ...

How do we get ImageMagick 6.9.1-2 to produce the same results as the older version? I am not sure but is it what you want? convert -background transparent -resize 1024x768 -fill '#AAAAAAB8' -font Arial -pointsize 50 label:'Test Stamp' PNG8:test.png identify -verbose test.png ... Alpha: graya(0,0) #...

But by negating the extracted alpha channel, the following works fine for me on IM 6.9.1.9 Q16 Mac OSX. convert 2mgnsdh.png -colorspace CMYK 2mgnsdh.tif convert 2mgnsdh.tif \ \( -clone 0 -alpha off +level 10%x70% \) \ \( -clone 0 -alpha extract -negate \) \ \( -clone 1 -clone 2 -compose multiply -c...

IM seems to have -alpha extract in CMYK negated. However, I am not that used to processing in CMYKA, so perhaps there is another reason (like CMYK without profiles typically displays as a negated version of RGB and needs to have a negate somewhere. Thank you very much! This is what i missed and con...

Import.exe and display.exe are no longer included because we stopped supporting X11 under Windows a while ago. Cygwin still provide import.exe and display.exe at least in their latest 6.9.1-3. Does it means these are not reliable on Cygwin? And is it because you found some technical limit or diffic...

I tried your script with CMYK tiff image simply created with convert -colorspace CMYK 2mgnsdh.png 2mgnsdh-CMYK.tiff (To compare I also created 2mgnsdh-RGB.tiff with "convert 2mgnsdh.png 2mgnsdh-RGB.tiff". ) I soon noticed all CMY values of this tiff is 0 so I add -channel K for +level: con...

Just a info.
Can display with 6.9.1-3 Q16 on Cygwin
Cannot display with 6.9.1-8 Q16 (HDRI binary) on Windows

Thank you, Fred. My first trial was to create 100%x0% one of your script step by step. Hope your script is the answer of the original question.

Today I learned a lot from you using -clone. I really appreciate some experts like you are here.

Just a guess. You wanted to apply the given image as a gradient to itself, and want to get 8bit alpha image. I'm not an expert, but I will try Given image (name 2mgnsdh.png) is 176x202 and has 1 bit transparent color #F6F6F6. So > convert 2mgnsdh.png -negate tmp.png > convert -size 176x202 'xc:#F6F6...

$convert logo: logo.png $ld.so.1: convert: fatal: libpng14.so.14: open failed: No such file or directory so, i downloaded the delegate libpng-1.6.16.tar.gz from the IM site and un-tar/gz 'd it. it's a directory and wondering if that get;s installed and how It that case, you have to download libpng-...

libpng14.so.14 => (file not found) This would seem to me to imply that libpng was not installed when the binary was compiled by the IM developers when the Solaris binary was created (or it installed some other version, but is looking for this one). So a potential bug? I am not the expert on this. S...

Because i had issues with the ImageMagick-sparc-sun-solaris2.10.tar.gz downloaded from ImageMagick site, for lack of executable 'configure' in the entire directory. Download file from ImageMagick site is binary, so it doesn't need to configure. You will be use it with adding proper LD_LIBRARY_PATH....

i resorted to downloading IM-6.8.6.9 from other source and still trying to run the very basic to test IM working i go to the directory where i have images and issue: >identify <image>.gif >ld.so.1: convert: fatal: libpng14.so.14: open failed: No such file or directory So, if you are sure your ident...

Hi, Being new to both IM 6.7 and Solaris10-sparc, i found that i have to feed each error with the packages IM is looking for to make it working by testing convert logo: logo.gif per IM's instructions. After installing the required libpng1.2.49 , i still get the error > convert logo: logo.gif > ld.s...

convert is not in PATH (/usr/bin) but in /usr/local/bin even when i issue that command from local/bin , > ldd 'which convert' > ldd: which convert: cannot open file: No such file or directory thanks I think you have already solved your main problems, but using ldd is good practice to help solving s...
