Re: Image looks different after removing transparent space and scaled

Post the input image alone. It is likely a profile issue.

Re: Batch converting in imagemagic

Create a new folder to hold the output. CD to the directory with your input image. Then use mogrify to process all the images in the folder with the following mogrify -format png -path path_to/newfolder -repage -1-4 -background black -flatten *.png It will loop over each image in the old directory a...

Re: Large 1bit Tiffs take forever

For ImageMagick 7, use magick, not magick convert. You should change your policy.xml file rather than setting -limit ... I believe they only restrict and do not allow you to increase values.

Re: Batch images rotation

If the rotation is the same for all images, you can do that with mogrify in ImageMagick on a whole folder of files. It loops through each image in the folder. Alternately you can write a script to loop over each image and do that. Cubic Convolution would be -filter Catrom. If you know Python, then y...

Re: Detecting multiple images in one image file

Do a fuzzy flood fill at some pixel that is the background. See -fuzz XX% -draw "alpha x,y floodfill" at https://imagemagick.org/Usage/draw/#matte (alpha replaces matte in IM 7). Use as small a fuzz value as you can. For JPG images, the compression makes the background uneven. I have found...

Re: Canvas size using "Montage"

try +smush with a negative value for each row, then use -smush with a negative value to combine all the rows.

Re: Adding a caption to an extent araea

With ImageMagick 7, use magick in place of convert. Try this: http://www.fmwconcepts.com/misc_tests/caption_test/lena.png Windows code (converted from Unix) magick lena.png -set option:wd "%w" ^ ( -size "%[wd]x150" -background gray -fill red -gravity center ^ -font Arial caption:...

Re: Crop and combine?

Please post an example of your input and desired output. What areas need to be cropped? Are they rectangular or irregular? Stacked in what way -- top to bottom or composited over each other.

What is your platform, as syntax may differ as would scripting.

Re: Resize height command operating on wrong axis

Your first command -resize x1080 should have worked. Please post an example image that failed. Perhaps it needs to be auto-oriented first. Your second command will be the same as 1080x1080 and will resize the largest dimension to 1080 and the other in proportion. So if the image is portrait (w<h), i...

Re: OSX - display: delegate library support not built-in '' (X11)

You said your version was OSX 10.14 Mojave. But the only version of ImageMagick binary for Mac on the Binary page at https://imagemagick.org/script/download.php#macosx says: ImageMagick-x86_64-apple-darwin17.7.0.tar.gz download download macOS High Sierra So that may be your issues.

You should launch XQuartz, but still issue your commands in the normal Mac Terminal Window, which should be a bash window.

Re: How to create drop shadow on resized image with an extension?

If the +X+Y in the shadow arguments are different, compute the shave values separately with the same formula. It is the same for landscape or portrait. The shave AxB where A is the amount to shave on the left and right sides and would be computed from +X. Likewise, the B is the amount to shave on th...
