Hi there,
Another problem with PS_Start/PS_End and ImageMagick:
When I try to create a simple plot, ImageMagick reports an error:
IDL> PS_Start, Filename='C:\temp\test.ps'
IDL> cgplot, indgen(100)
IDL> PS_End , /png
I get the following:
PostScript output will be created here: C:\temp\test.ps
ImageMagick CONVERT command: convert -alpha off -density 300 "C:\temp\test.ps" -resize 25% -flatten -rotate 90 "PNG24:C:\temp\test.png"
Magick: `%s' (%d) "gswin32c.exe" -q -dQUIET -dPARANOIDSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dEPSCrop -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r300x300" -g1854x2967 " -sOutputFile=C:/DOCUME~1/gue026/LOCALS~1/Temp/magick-ZY0nvQM 2--0000001 " "-fC:/DOCUME~1/gue026/LOCALS~1/Temp/magick-Uekxe77J" "-fC:/DOCUME~1/gue026/LOCALS~1/Temp/magick-1PbnxUTh" @ error/utility.c/SystemCommand/2094.

Magick: Postscript delegate failed `C:\temp\test.ps': No such file or directory @ error/ps.c/ReadPSImage/806.
Magick: missing an image filename `PNG24:C:\temp\test.png' @ error/convert.c/ConvertImageCommand/3011.
The file C:\temp\test.ps is indeed created but ImageMagick doesn't find it.
I am running the latest version (6.7.3-2), just updated from a previous version but the problem persists .
Any ideas?
Thanks!
JP

File permissions? Don't know.
I'd open a Windows command prompt and see if you
can somehow get ImageMagick to work on its own.
It would seem to be installed properly, and the command
from inside of IDL looks right.
Has to be file permissions, I think.
Let us know.
Cheers,
David

maybe people should read the documentation first? ;)
from PS_End:
If `ImageMagick ` is installed
on your computer, you can easily convert PostScript output to GIF, JPEG, PNG, and TIFF
raster output. If `Ghostscript ` is installed
you can convert PostScript output to PDF files.
from cgPlot:
All raster file output is created through PostScript intermediate files (the
PostScript files will be deleted), so ImageMagick and Ghostview MUST be installed
to produce anything other than PostScript output.

BTW, and I already knew about this, ImageMagick doesn't like network paths such as:
\\wron\working\
it needs to map the network drive first
David, if you are going to update the user instructions in your scripts it may be worth saying that?

Bingo!!
Yes, that's the problem. Installed Ghostscript and all working now!!
now I see some people have mentioned this in the ImageMagick forums...
Thanks!

Thanks David,
It definetely is a problem of file access by convert, nothing wrong with PS_Start/PS_End whatsoever. But I am trying to understand what is going on and can't understand it. A colleague here tried that bit of code and no problems.
ImageMagick is installed in my machine.
if i manually copy a file called cgWindow.png into c:\new and type in a command prompt:
convert cgWindow.png cgWindow.jpg
it works, no problem. And i get my new file
then i try:
convert cgWindow.png cgWindow.ps
also works, i get a postscript.
However, then i try:
convert cgWindow.ps cgWindow.png
and get a similar error message as when i try it from IDL via PS_End.
it's like convert doesnt like postscript here :(
very frustrating.
