Re: Lightroom color adjustment to imagemagick command line

Unfortunately, Lightroom is proprietary code. We do not know exactly what they do. It would take quit a bit of time for anyone to try to guess at what they do and make tests with different Imagemagick functions varying the arguments to to see if it can be matched. Apart from the sharpness issue, you...

Re: Copy EXIF, IPTC and XMP metadata from one JPEGfile to another

Let me clarify my comments. Imagemagick will copy exif data from an input to an output. I know of no universal way that allow imagemagick to transfer appropriate exif data from one image to some other arbitrary image. I will defer to the developers for a definitive response.

Re: PNG to JPEG: how is background color determined?

P.S. the background color in identify -verbose may be totally unrelated to what I have described above. I am not sure what the identify -verbose background color actually means. One of the developers or other users would have to comment with more definitive information.

Re: PNG to JPEG: how is background color determined?

Your link to the post is not accessible. So I cannot look at it. It may be that typically the background color under transparent regions is black and when you save to JPG it will show black. But if you use -background white -alpha background and save to JPG, that should create a white background. Th...

Re: PNG to JPEG: how is background color determined?

You must specify -background somecolor before using -alpha background. But those commands simply change the color of the background in the base image for which the pixels are transparent. The default for -background is white, as I recall. Is this what you are trying to do?

Re: Convert Font?

Here is my same answer form stack overflow. On some tools that make use of Imagemagick, the tools do not use the system ENV variable. So I have seen cases such as with PHP Imagick where Ghostscript cannot be located from the delegates.xml file. In those cases the solution was to put the full path to...

Re: TIFF format change

Imagemagick 5.2.3 is so ancient it is likely that there have been much changes between that and IM 6 and even more to IM 7. In Imagemagick 7, you must preface mogrify with magick. Also convert is simply replace by magick. See http://imagemagick.org/script/porting.php#cli I recommend that you use mag...

Re: extracting biggest square from a rotated image

If you know the size and rotation angle, then use GeeMack's solution. My autotrim assumes that the whole rotated image is from which you want to get the inner bounding rectangle. You want the inner area of just your fingerprint after rotating. These are two different situations.

Re: Problems with -density if -unit PixelsPerInch not specificied before input image

I will just add a note. Imagemagick processing is not done in the same order as typical Unix commands. Although IM 6 is forgiving in many ways, IM 7 is very strict in the order of things in the command line. See https://www.imagemagick.org/Usage/basics/#cmdline and the following sections about order...

Re: Removing a shadow from an image

No, I have never had much success in these situations. If the shoes are a different color from the shadow and the background is white, then you have a chance. But not with either near black or near white shoes.

Re: Removing a shadow from an image

Shadows are particularly hard to remove as per isolating the objects from the background. I am not sure there is any good way to do that in Imagemagick when the shadow color is close to the object color. I will defer to anyone with a good suggestion. You could try one of tools such as clipping magic...
