+ | ===== ImageMagick convert, memory issue ===== | ||
+ | |||
+ | Executing **convert** on very large images can lead to memory exhausted issue. I experienced it converting a TIF scan into PNG (because I wish to avoid 24 bit Gimp limitation with TIF images): | ||
+ | |||
+ | < | ||
+ | convert very-big.tif very-big.png | ||
+ | convert-im6.q16: | ||
+ | convert-im6.q16: | ||
+ | convert-im6.q16: | ||
+ | </ | ||
+ | |||
+ | It seems that ImageMagick is self-limiting the disk resource it will use, you can fix the configuration file **''/ | ||
+ | |||
+ | <code xml> | ||
+ | < | ||
+ | <policy domain=" | ||
+ | <policy domain=" | ||
+ | <policy domain=" | ||
+ | <policy domain=" | ||
+ | <policy domain=" | ||
+ | <policy domain=" | ||
+ | </ | ||
+ | </ | ||
+ | |||
+ | May be you can also increase the Memory resource, if you have enough: | ||
+ | |||
+ | < | ||
+ | convert -list resource | ||
