ruby on rails - Error "cache resources exhausted" with Imagemagick -


i'm using imagemagick on rails app minimagick , generate pictogram it.

when launch process have error , don"t find solution

minimagick::error (`convert -limit memory 2gib -limit map 2gib -limit   disk 4gib -background none -fill #000000 -font ttf/selis006n.ttf -pointsize 300 label: s public/pictogram_images/recintan-el-064-layer-1.png` failed error: convert.im6: cache resources exhausted ` s' @ error/cache.c/openpixelcache/4078. convert.im6: no images defined `public/pictogram_images/recintan-el-064-layer-1.png' @ error/convert.c/convertimagecommand/3044. ):

my process simple, have .tff file , each character pictogram. want generate preview of character in png

not sure item causing problem, 1 of these:

1) need put font imagemagick's xml-based font file rather specify file.ttf in convert command. list of available fonts, use

identify -list font | more  path: /users/mark/.magick/type.xml          <--- edit font here   font: acaslonpro     family: unknown     style: undefined     stretch: undefined     weight: 0     glyphs: /library/fonts/acaslonpro-regular.otf   font: acaslonpro-semibold     family: unknown     style: undefined     stretch: undefined     weight: 0     glyphs: /library/fonts/acaslonpro-semibold.otf ... ...

at beginning see path config file fonts , need edit include ttf file mentioned. if have lots of fonts add, may automate process - see other post here.

2) may need escape # in -fill option, or @ least surround single, or double quotes hide shell, if minimagick invokes via shell - don't know ins , outs of minimagick.

3) may need quote letter s wish output inside single or double quotes.

4) may need remove space after colon following label.

what getting @ command should maybe more this:

convert -limit memory 2gib -limit map 2gib -limit   disk 4gib -background none -fill "#000000" -font "timesnewroman" -pointsize 300 label:"s" output.png
