Re: choose starting frame (different than frame 0) for a GIF

If you have read many images and want your GIF to start after the first 25 of those images, you can move those to the end of the list:

Code: Select all

magick *.png ( -clone 0-24 +write mpr:FIRST -delete 0--1 ) -delete 0-24 mpr:FIRST out.gif

Re: Large 1bit Tiffs take forever

Is there a way to tell which limit is causing the disk cache to happen by looking at the debug log? Yes. Search the log for "Disk" and look at the previous entry. For example: magick -debug resource -limit area 0 toes.png -blur 0x1 NULL: 2>x.txt Two entries in the log are: 2019-10-05T15:4...

Re: Image looks different after removing transparent space and scaled

I am new to image processing, could you recommend what's the right way to view it? like by which software? There is no "right" way. Images with transparency are always shown flattened against some background. A chequerboard background is traditional because it clearly shows which areas of...

Where? If you have a chequerboard background, or any non-constant background, that will create a difference. But the difference is because of the way you are viewing.

Re: Image looks different after removing transparent space and scaled

I can see no difference between the linked images, except for the border. They have partial transparency, so when viewed against a dark/light chequerboard background, the dark/light squares occur at different places.

Re: Image looks different after removing transparent space and scaled

What version of IM, on what platform?

I suggest you link to actual PNG files, not a screen shot.

Re: Keep color correction when converting

The two files each contain one Color Filter Array, and a full-size JPEG. The "color corrected" version has almost the same CFA image, but the JPEG is clearly edited. Exiftool shows editing has been done by Adobe tools. The point of a DNG file is to make a vendor-independent version of the ...

Re: Combine two complementary parts of images - Spherical pictures

What version of IM, on what platform? Please show sample input images. If the only change is the position of you, the photographer, then the task is simple: the output will be one of the photos, composited with part of the other photo. The boundary between the two might be a straight line, or with a...

Re: Need help upgrading script

The labels ":Normal" and ":Big" are mising. I suppose you have removed those sections for brevity.

You have "-label %%f". Perhaps you want %%t instead.

Re: Large 1bit Tiffs take forever

Is there a debug or something I can do when running the full command to show the actual settings used during processing? Insert "-list resource" to find the settings at that point in the command, eg before or after your "-limit" settings. As Fred says, "-limit" can onl...

Re: Batch images rotation

korr4k wrote:Do you think that the same operations are possible with IM?
Yes. The basic command could be:

Code: Select all

magick in.jpg -filter XXX -rotate 0.2 out.jpg
... where XXX is a named filter. As you may know, you shouldn't use JPG unless you really have to.

You probably need a shell loop to process all the files.

Re: Keep color correction when converting

"Tint, exposure, highlights" etc are settings made within the camera, as hints to software either within the camera when making JPEGs or external software, eg readers of raw files. Each manufacturer has their own definition of these fields, and they don't publish the definitions.
