How to convert an image into cylinderical image usng imagemagic?

[imran_ullah]

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?

[fmw42]

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

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!
