Magick montage

I made an interesting (magick ?) montage: every image row has the same height, furthermore average image luminosities were taken into account when determining the place of the images, here is the result: https://i.imgur.com/AAVicPF.jpg Click on the image for higher resolution. Brighter images were p...

ImageMagick Policy Configuration

I increased the settings "area" and "memory" in the /usr/local/etc/ImageMagick-7/policy.xml file, but I still get the same error message, exactly: magick: unable to extend pixel cache `Siker' @ fatal/cache.c/CacheSignalHandler/3182.

Re: I get "segmentation fault" error everytime starting convert

Unfortunately changing the order of input files and the operator doesn't solve the issue, I get the same error message in both cases. Maybe the resulting image is too big, and doesn't fit in the memory as I have only 512 MB in the VPS. My individual images are 2076x902, I tried appending only the ha...

Re: I get "segmentation fault" error everytime starting convert

I am trying to simply append 14 jpg files, vertically, so I use command:

Code: Select all

convert -append 4_*.jpg  examine_gamma_4.jpg
I still get an error message:

Code: Select all

convert: unable to extend pixel cache `no such file or directory' @ fatal/cache.c/CacheSignalHandler/3182.

Re: How to threshold an image to get about same amount of black and white?

Sometimes the histogram data is provided in a different way, which doesn't show the usual graylevels, I have no clue why: Histogram: 1: ( 19, 19, 19) #131313 srgb(19,19,19) 2: ( 20, 20, 20) #141414 grey8 4: ( 22, 22, 22) #161616 srgb(22,22,22) 4: ( 23, 23, 23) #171717 grey9 8: ( 24, 24, 24) #181818 ...
