How to convert an image into cylinderical image usng imagemagic?

A plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations.

On my directory the displace.png is generated only but then the script aborts. I also want to know why do I need the displace.png?

Your question is vague.

What version of IM, on what platform? What script are you using? What is your exact command? What are your input images?

What is the revision version of the script. It is at the top of the script. The current version is dated 12/31/2018.

What is your exact version of ImageMagick 6.8.x.x. Use convert -version. Nevertheless, 6.8 is rather old.

Since you are using -m vertical, the script should never get to line 933, which is used when -m horizontal is set. So I do not know what is happening.

I think that error might be coming from your OS and not ImageMagick. Do you have enough space in your /tmp directory. Perhaps it is filling and ImageMagick crashes due to too little space to work. How big is your image? Can you post a link to your image here?

The displacement image is created by the script to control the actual warping. See https://imagemagick.org/Usage/mapping/# ... ement_maps and https://imagemagick.org/Usage/mapping/# ... e_cylinder where a simpler form of the cylinderize is shown. Perhaps that code will be all that you need.

I have the same problem which imran_ullah. It would be really nice if you can help!

My imagemagick Version: ImageMagick 6.9.7-4 Q16 x86_64 20170114 http://www.imagemagick.org
My OS version: Ubuntu 18.04.1 LTS (GNU/Linux 4.15.0-43-generic x86_64)
The script version is: Developed by Fred Weinhaus 5/1/2009 .......... revised 12/31/2018

I tried using different image, event the 'sharks.jpg' from your example but still have the same problem. I also tried different argument for testing but It's also the same. Here are some of my commands that I used:

Code: Select all

./cylinderize -m vertical sharks.jpg a.png
./cylinderize -m horizontal sharks.jpg a.png
./cylinderize -m vertical -r 73 -l 120 -w 90 -p 5 -n 94 -e 2 -a 100 -v background -b none -f none -o +24+10 sharks.jpg a.png
The error is:

Code: Select all

./cylinderize: line 933:  6210 Aborted                 convert $tmpA1 $flipping $rotating $outfile
After digging deeper, I have some more information for you. The actual line of code generating error is the line 829 " convert $tmpA1 $flipping $rotating $outfile".

After debugging, I have saved the tmpA1 file and try running the command separately. In which,

the $tmpA1 file ('./cylinderize_1_13475.mpc') has content

Code: Select all

id=MagickCache
magick-signature=1018107213

exif:YCbCrSubSampling={2, 2}
jpeg:colorspace=2
jpeg:sampling-factor=2x2,1x1,1x1
And the command convert -debug ./cylinderize_1_13475.mpc a.png resulted error:

Code: Select all

convert-im6.q16: unrecognized event type `./cylinderize_1_13475.mpc' @ error/convert.c/ConvertImageCommand/1226.
Please let me know which information you need so I can provide you more. Thanks a lots!
