This complain about parenthesis

magick: unbalanced parenthesis `(eof)' in "heatmap.mgk" at line 7,column 17 @ error/magick-cli.c/ProcessScriptOptions/272.

If I put a - in front of radial-gradient it doesn't error like this, however when I attempt to execute the script, it hangs on the first gradient forever.

"-composite" needs two images, as it wants to add one to the other. But you have only provided one. (You removed "xc:black" from my script.)

[DrEvil]

I can't get xc:black to work in the v7 script either. The script errors

What was the exact code you used? Did you try using canvas:black in place of xc:black? Did you provide the -size before using xc:black?

[DrEvil]

Code: Select all

-gravity center

-print 'Generating Image Buffer\n'
-size 1000x1000
#canvas:black

-print 'Rendering Gradient 1\n'
( -size 100x100 -radial-gradient: ) -geometry +300+300 -compose Plus -composite
-print 'Rendering Gradient 2\n'
( -size 100x100 -radial-gradient: ) -geometry +180+80 -compose Plus -composite
-print 'Rendering Gradient 3\n'
( -size 100x100 -radial-gradient: ) -geometry +180+80 -compose Plus -composite

-print 'Colorizing Heatmap\n'
-auto-level
(
	-size 1x250
	gradient:#004-#804
	gradient:#804-#f00
	gradient:#f00-#f80
	gradient:#f80-#ff0
	gradient:#ff0-#ffa
	-append
) -clut

-print 'Writing Heatmap\n'
-write heatmap_coloured.png
-exit

This script hangs on the first gradient. Errors if you comment back in the canvas line(whether it's xc or canvas)

Here's the error with the canvas line in

try a simple command

magick -size 100x100 xc:black tmp.gif
or
magick -size 100x100 xc:"black" tmp.gif

or

magick -size 100x100 canvas:black tmp.gif
or
magick -size 100x100 canvas:"black" tmp.gif


Does that give errors?

In your command is there a space after -size 100x100 and after xc:black (which is currently commented out)?

[snibgo]

Try the command with "-debug all". How far does it get? Does it look for IM_MOD_RL_XC_.dll in a subdirectory of the place you installed it? Is that file (and many other dlls) present? If the file isn't there, or IM isn't looking there, then you have an installation problem. A re-install might cure it.

[DrEvil]

Yes none of those work just running them raw from the command line by itself, no script or pipe file. Same error about black.

Reinstall doesn't do anything different.

BUT If I copy all the files from ImageMagick-7.0.0-Q16\modules\coders into ImageMagick-7.0.0-Q16\ it finally works.

Perhaps this is now an installation problem instead.
