Re: Pixelate part of the image

If the part that you want to pixelate is a rectangle/square, you can use -region to do the -scale 10% -scale 1000% operation. See https://www.imagemagick.org/Usage/masking/#regions magick in.png -region WxH+X+Y -scale 10% -scale 1000% +region out.png This works in IM 6 but for some reason, not in IM...

Thanks for Your Reply.

Can you Know how to Remove vertical lines in Images.
Please supply an example image. Often, you can use -morphology with a custom linear kernel to remove lines.

Re: Scan Image Preprocessing to OCR

My textcleaner script will not help those kinds of images. My textcleaner will not work on Windows except via Magick.NET. See https://github.com/dlemstra/FredsImageMagickScripts.NET I do not know how to improve those images. You could try some morphology close, but it might remove the dots, but make...

New Script To Compute Perceptual Hashes

I have just added two new scripts. The first, phashes, computes and stores one or more perceptual hashes for all provided images. Any or all of four different binary string perceptual hashes are available: block mean hash (bmh), block difference hash (bdh), Annular Variance Hash (avh) and Polar FFT ...

Re: Windows cr2 conversion color issues

Is it correct to add these things to the delegates.xml in the main folder of the installation, or do I have to put it somewhere else?
It should be in the directory where ImageMagick installed it, not the one in the download folder. Perhaps that is what you meant, but just wanted to make sure.

Re: Detect images with drops with ImageMagick

Do edge detection and compute the density or amount of edges. Blurring from the water drops will not produce high quality edges. To compute the density of edges, you can threshold the edge detected image and then measure the average (mean) gray level in the image. Edges can be computed in many ways:...

Re: Colour balancing - green reduction - changed the question

One suggestion would be to process the original in Photoshop or GIMP. Then create 3D Hald image in ImageMagick and take it to your Photoshop or GIMP, then apply the same adjustments (as long as they are global changes and not local such as sharpening or convolutions) to the Hald Image. Then bring th...

Was that the original or the result? It might help if post both, so others can experiment.

Re: No matter what, second parameter of convert always invalid.

IM 7 uses magick. When you use convert, it is actually running the legacy IM 6. So if you really want the new features of IM 7, then use magick, not convert.

Re: Discrepancy in File Size reading between Photoshop and OS+ImageMagick

If you start with an uncompressed file, then when converting with Imagemagick set -compression none to get an output uncompressed file. I see no connection between flattening and compression. If you want to save space, you should use lzw compression or one of the other non-lossy compressions. Since ...
