Re: Create an animated "contact sheet" of gifs

I think you would need to write a script for that.

Re: animate in Window x11

Microsoft Windows doesn't include X-windows. Perhaps X-windows can be installed on top of Microsoft Windows.

Re: Create an animated "contact sheet" of gifs

I'm not sure what you want. Perhaps you have a number of animated GIFs, and you want to create a single GIF that is made from the input GIFs placed side-by-side or below each other, or in a grid. This is easily done by keeping the GIFs separate, and showing them on an HTML page. Combining them into ...

Re: Getting a perimeter and filling in the rest

Your required output has a wide black margin on the right. I don't know where that has come from. Ignoring that, we can floodfill to isolate the outer black border. That gives a rough edge we can smooth with a blur. The blur has to be large enough to help, but not so large that it damages the curved...

Re: Getting a perimeter and filling in the rest

What version of IM, on what platform?

What mask do you want? The central rectangle, or that plus the enclosing black area, or that plus the enclosing white area, or what?

That's not correct. "-a" is a parameter to dcraw, which does the white balancing.

Re: Resizing all my jpg Images in Wordpress Uploads Folder

Not within IM. In a shell script, for each file, you could find the current compression "quality" level. If it is more than 70, then run the command to compress it.

Re: Resizing all my jpg Images in Wordpress Uploads Folder

...like if a File is already compressed to the maximum by a 3rd party plugin... Maximum compression is a really bad idea. The result will look awful. JPEG compression is a trade-off between image quality and file size. Smaller files have worse image quality. What will Imagemagick do with the Imagef...

Re: Resizing all my jpg Images in Wordpress Uploads Folder

I have installed ImageMagick 6.7.8-9. That is very old. I suggest you install a current version. What command should be used, convert or mogrify? If the command is simple, mogrify would work. Otherwise, use convert to process one file at a time, and put that in a shell loop. I would like to remove ...

Re: Keep color correction when converting

IM can (via a delegate such as dcraw) read the raw image from the DNG. Exiftool can extract the JPEG from the DNG file.

I don't have Adobe tools. I expect they can read the raw image from the DNG file, and apply transformations, and save the result to a format such as 16 bit/channel/pixel TIFF.

Re: Keep color correction when converting

You mean to say the jpeg preview file has been edited and attached rather than creating from the dng file? I don't know what made the JPEG preview. But it is clearly different to the raw image, more "corrected". Could you please tell me which exiftool metadata you are referring too? exift...
