I want it to end up like this batch_file.bat How can I fix this?Įrror message : convert: unable to open image 'photo': No such name or directory convert: no decode delegate for this image format '' error/constitute.c/ReadImage/554.** Some files have spaces in their name and cause the error. I suggest writing a script that contains a loop and builds the final command or script.I'm trying to loop over a bunch of folders, create subfolders then loop on the files, convert them with imagemagick and put them into the new subfolders and rename them. Then you could rearrange the order of the images in the list and insert a dummy "NULL:" image, so you have 17 images: the odd numbers, then NULL:, then the even numbers, Then use "-layers composite" to plus each pair. You might instead directly crop the 512x2048 image into 16 pieces. You crop the 512x2048 image into 8 pieces, then crop each of those into 2 pieces, and "-compose Plus -composite" each pair. Add a dummy image at the start to number yours from one upwards. Hence if you arrange to have a list of images, you can automatically annotate them from zero upwards. "-annotate" can take metadata escapes shown on, so you can use "Section %p". I would add "+repage" after the final "-append" because more recent versions of IM take the canvas size from the size of the first image. For jobs like this, I often write a script that contains a loop and builds the final command or script. IM doesn't have a looping construct to simplify the code. I can't see any scope for increasing performance. \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 8" \) -delete 0 \ \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 7" \) -delete 0 \ ![]() \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 6" \) -delete 0 \ \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 5" \) -delete 0 \ \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 4" \) -delete 0 \ \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 3" \) -delete 0 \ \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 2" \) -delete 0 \ ![]() \( -clone 0 -crop 512x128 +repage -compose Plus -composite $bright $annotate "Section 1" \) -delete 0 \ size 512x2048 cmyk:test.raw -set colorspace Gray -separate -average -normalize -crop 512x256 +repage \ (The real version is bigger and has more than the 8 sections in my example)Īnnotate="-gravity north -stroke #FFFF -fill white -strokewidth 1 -pointsize 15 -annotate 0"īright="-brightness-contrast 50x50 -black-threshold 20%" Is there a better way to loop in ImageMagick? Or a better way to do this? The single command below "works", needs no temporary files and is faster than the bash script, but I had to use the clone commands exactly the right number of times and hardcode the section names. I wrote a bash script to do it but it runs a bit slow. Then I need to convert everything into 1 final output image. I need to overlay pieces 1 and 2, 3 and 4, etc. I need to read a raw image and split it into 16 pieces.
