Re: Resize 'blur' option not working on 'wand' library.

Your question is about a Python interface, not the C MagickWand interface, but there is no IM Python forum. I think an old interface to IM had "blur" as a parameter to "resize". But that changed long ago, so now we have "-define filter:blur=n", as an expert setting that is rarely used. See http://ww...

Re: scripting / processing multiple images

You have removed the keyword "-write", so IM will read those files instead of writing them. Again, you are building the image list.

Re: Copy a certain CMYK color from one image to another image

If image2 has only white and some other colour, and you don't want the white copied, then...

Code: Select all

convert in1.jpg ( in2.eps -alpha set -transparent icc-color(cmyk,0,0,0,0) ) -composite out.tiff
I write to tiff instead of jpg because tiff is by default lossless.

Re: Copy a certain CMYK color from one image to another image

What version of IM, on what platform?

I suggest you don't use the "composite" command. Instead, use "convert" in v6 or "magick" in v7, with a "-composite" option.

Why are you multiplying pixels?

Re: scripting / processing multiple images

IM works on lists of images in memory. Each read adds an image to the list. "+delete" removes the last image from the end of the image. (When there is only one image, this leaves the list empty.) It doesn't delete files. See http://www.imagemagick.org/script/comma ... php#delete

Re: Copy a certain CMYK color from one image to another image

I think you want to composite the second image over the first, but only after making other colours transparent, like this: magick in1.jpg ( in2.jpg -alpha set -fuzz 0.5% +transparent icc-color(cmyk,0,0,0,0) ) -composite out.jpg The icc-color numbers are in the range 0.0 to 1.0. I'm not sure how you ...

If you don't have that, the second "-write" will write two files, the third "-write" will write three files, and so on. A v7 script file can contain any IM options except for "-script" (so s...

Yes. The IM script facility has no limit, as far as I can see. I have tested it with long scripts, eg 100KB.

Re: How to convert many tga to dds?

This does not work. Because the command is wrong. Your "-format dds" would be okay in mogrify, but in convert it sets the format for "info:". So remove that. Your output file is "C:\Img\*.dds". But that won't do what you want. I suggest you use something like "C:\Img\myfile_%d.dds" which will makes...

Re: How to convert many tga to dds?

To process all the files in a folder, I suggest you either use "mogrify" instead of "convert", or use a "for" loop.

Re: density unit output

Gimp can't process CMYK images, so those are converted to sRGB when they are read. To find the colorspace of the jpg file, I suggest you use exiftool.

Re: density unit output

What is wrong with your result?

I guess your nBmpPrm.dpi was 150, and 150 dots per inch is 5.9 dots per millimetre.

Re: Watermark visible in every editor/image viewer except Photoshop

As Fred hints, original.tif contains two images. So the OP command ... magick original.tif watermark.png -gravity center -composite result.tif ... reads these two images, then a third image "watermark.png". The "-composite" operation places the second image over the first, using the third as a mask....

Re: Converting to monochrome bitmap for printer

A printer usually comes with a driver , software that reads an image file and formats it for the specific printer. It usually has options for paper size, darkness adjustment, etc. So you shouldn't need to bother about the exact format the printer wants. But if there is no driver, and you need to sen...
