Using saveGIF: error occurred in the conversion

[weianuk]

I tried the following codes to use saveGIF function in my RStudio,

library(animation)
# Sys.getenv("PATH", "C:\\Program Files\\ImageMagick-7.0.6-Q16")
ani.options(convert = 'C:\\PROGRA~1\\ImageMagick-7.0.6-Q16\\convert.exe')
saveGIF({
  for (i in 1:10) plot(runif(10), ylim = 0:1)
})

But it gives the error below:

convert.exe: unable to load module 'C:\Program Files\ImageMagick-7.0.6-Q16\modules\coders\IM_MOD_RLPNG.dll': The specified module could not be found. @ error/module.c/OpenModule/1266. convert.exe: no decode delegate for this image format PNG' @ error/constitute.c/ReadImage/509. convert.exe: no images definedanimation.gif' @ error/convert.c/ConvertImageCommand/3275.

Is there something wrong in my setting? Tried the solutions from previous threads, e.g. ADMIN running, but still error. Hope for helps on my problem. @yulijia @yihui
Thanks in advance.

Could you mind re-install ImageMagick, from the error message, I think ImageMagick is not installed correctly. Also the R environment cannot find convert.exe in your computer.

@yulijia thanks. Just re-installed ImageMagick, and already set the PATH again: Sys.getenv("PATH", "C:\Program Files\ImageMagick-7.0.6-Q16"). but it still has the error below:

'C:\PROGRA~1\ImageMagick-7.0.6-Q16\convert.exe' is not recognized as an internal or external command, operable program or batch file. an error occurred in the conversion... see Notes in ?im.convert

Could you find convert.exe in your ImageMagick directory? If not, that's because you don't install it.

Problem solved now.

There is no convert.exe. Imagemagick 7 uses the "magick" command in place of "convert". Therefore, use saveGIF should call magick.exe rather than convert.exe if IM7 was installed.

It is suggested the ani.options documentation could be updated for this.

Thanks, we will include magick on dev #98
