In R using the system() command with the correct "-set delay x" I was getting error: 我通过导航到目录并运行该行,首先在命令提示符下工作 convert -set delay 80 -loop 0 *.jpg example_cmd_test.gifīefore this I was using -delay = 80 rather than -set delay 80 in cmd and got error: convert: invalid argument for option '-delay': = error/convert.c/ConvertImageCommand/1277. I got it working first within command prompt by navigating to the directory and running the line loop 0 = loop forever, if set to 1 it will go through the images once set delay x = set the delay time between each frame to x (1000 = 1 second) Within cmd each command means the followingĬonvert = open convert function from ImageMagick
IMAGEMAGICK INVALID PARAMETER WINDOWS 10
I'm a windows 10 user, after defining the working directory I got it working in R using How can i get ImageMagick to run through R? I also tried specifying the whole string of the convert.exe file, but also without luck. I've tried to change the Windows PATH enviroment variable in the systems properties, as suggested in this answer, but the PATH-variable was allready corectlly defined on my system. Running command 'convert -delay 80 *.png example_1.gif' had status 4 In the comments to the website i am linking to earlier, it is suggested for Windows users to use "shell" instead of "system" to run external programs but none of the two work.
The problem is that R doesn't seem to finde the exe-file "convert" which is a part of ImageMagick and installed on the C-drive (C:\Program Files\ImageMagick-6.8.5-Q16). #shell("convert -delay 80 *.png example_1.gif") System("convert -delay 80 *.png example_1.gif") Next it calls for the external ImageMagick-program "convert" to compile the GIF animation.
