Re: how can I add a transparency gradient in a grayscale to an image?
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: ...

Re: How to draw text antialiased on alpha channel only
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) #...

Re: how can I add a transparency gradient in a grayscale to an image?
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...

Re: how can I add a transparency gradient in a grayscale to an image?
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...

Re: Useless installation files deleteable?
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...

Re: how can I add a transparency gradient in a grayscale to an image?
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...

Re: how can I add a transparency gradient in a grayscale to an image?
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.

Re: how can I add a transparency gradient in a grayscale to an image?
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...

Re: error: libpng14.so.14 - even after installing pkg libpng1.2.49
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...

Re: error: libpng14.so.14 - even after installing pkg libpng1.2.49
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....
