Re: Converting HEIC images with Display P3 color profile

@zkarj: Can your version of IM write HEIC files?

Code: Select all

f:\web\im>%IMG7%magick -list format |grep -i HEIC
     HEIC* HEIC      r--   High Efficiency Image Format (1.4.0)
This version (v7.0.8-64 on Windows 8.1) can read HEIC, but not write it.

Re: How to make a image in desired shape in imagemagick?

What version of IM, on what platform?

Your "%ProgramFiles%" suggests you are using Windows, but you escape \( and \) which suggests you are using bash. That is a problem. If you use Windows, see http://www.imagemagick.org/Usage/windows/

It works now, so I guess someone fixed something.

Re: Creating a color palette from an specifc color

"Palette" is a technical term, meaning that pixel numbers do not directly define colours. Instead, each pixel has a single number that is an index to a table (a "palette") of colours. IM does not supply tools to directly edit palettes. But perhaps you simply want to change colours in an image, regar...

Re: Lighten dark areas only?

As Fred says, you can apply Photoshop operations to a clut or hald-clut, then use that in IM. In IM alone, you can get as much contrast as you want. For example, change "-evaluate Pow 0.6" to "-evaluate Multiply 20". Then what was 5% becomes 100%. http://snibgo.com/imforums/samara_out2.jpg I think t...

Re: Lighten dark areas only?

I don't know what the problem is.

You say you tried the level and gamma methods, and IM worked. Did you use the same filename? The same "magick" command?

I suggest you show the complete BAT file, with all three commands.

What version of IM do you use?

Re: Lighten dark areas only?

The input JPEG has virtually no detail in the dark hair. We read the input file, samara.jpg. The first parentheses is the main transformation, "-evaluate Pow 0.6", which leaves black and white unchanged, and brightens mid-tones. The next parentheses define a mask. Where do we want the effect? We wan...

Re: Convert image into all known/available formats/extensions

What version of IM on what platform? I often loop through colorspaces, to compare results of an algorithm using different colorspaces. This is easy as "magick -list colorspace" has a simple output format. "magick -list format" has a slightly messy format, and you want just those formats that IM can ...

Re: Lighten dark areas only?

What version of IM, on what platform? I'll assume v7 on Windows. There are many ways of lightening shadows, depending on exactly what you want. For example: magick in.tiff +level 10,100% out.tiff This raises black to 10%, and raises lighter values less. Or "-gamma 0.8" will raise all values except b...

Re: Combine two psd files into one, keep filename

For some reasons the output file has 2 layers of the test-me-5.psd inside and they are all locked. As Fred says, PSD files contain multiple images. The first is a flattened version of all the others. So your two input files contain flattened versions, and these are copied to the output, and an extr...

Re: Bug in polynomial distortion

Yes, you can do the same trick with x, though that isn't needed in this example. For some sets of coordinates, a second unwanted copy might occur below or to the right of the wanted copy. You could find the maximum x and y output coords, and crop the result there. In extreme cases, that won't work: ...

Re: Combine two psd files into one, keep filename

What version of IM? I'll assume v7.

Code: Select all

magick test-me-1.psd test-me-5.psd test-me-1.psd
This reads the two input files, and overwrites the first. Is that what you want?

Re: Library producing 12MB MIFF images

As Fred says.

Sorry, I don't know about specific libraries on specific platforms. Your config.log will tell you what libraries have been included within an IM build.

Re: Library producing 12MB MIFF images

Can your build of IM write JPEG images? I suspect not, possibly because you haven't included a JPEG library.
