Image Magick commands taking too much time to execute.

Post by atf4_solace » 2017-09-15T08:13:03-07:00

Hi Team,

We are using sequence of commands to generate one output through imagemagic command.

Image used in first command is here - ... 50373.jpeg
Just for quick reference, here is what each command does.

Here are the commands.

Code: Select all

"/usr/bin/convert" 15049951621774150373.jpeg -scale 3600x2400! solace_tmp_0.png
cp solace_tmp_0.png solace_dummy.png
mogrify -extent 3600x2400 -background "#FFFFFF" -gravity Center solace_dummy.png
"/usr/bin/convert" solace_dummy.png -fill black -draw "color 0,0 reset" solace_dummy.png
"/usr/bin/convert" solace_dummy.png -draw "image over 0,0+3600+2400 '15049951621774150373.jpeg'" solace_merge_0.png
cp solace_merge_0.png solace_first.png
mogrify -extent 4800x3600 -background "#FFFFFF" -gravity Center solace_first.png
"/usr/bin/convert" solace_first.png -fill white -draw "color 0,0 reset" solace_first.png
"/usr/bin/convert" solace_first.png -draw "image over 600,600+3600+2400 'solace_merge_0.png'" solace_main_final.png
cp solace_main_final.png solace_first.png
"/usr/bin/convert" solace_main_final.png -font /fonts/arial/arial.ttf -pointsize 19.935 -fill red -annotate +0+3596 " Text 1 " solace_main_final.png
"/usr/bin/convert" solace_main_final.png -font /fonts/arial/arial.ttf -pointsize 19.935 -fill black -annotate +0+3596 " Text 2 " solace_main_final.png
"/usr/bin/convert" solace_main_final.png -draw "image over 1453,3521+75+75 'solace_qr_image.png'" solace_main_final.png

My Imagemagic installation details -
Version: ImageMagick 6.9.3-8 Q16 x86_64 2017-06-12
Features: Cipher DPC OpenMP

Execution of above commands take total 82 seconds at my end. Individual timings are mentioned as well above.

Can you please try running these commands at your server with same image and mention me how much total time its taking on your server?
If its taking less time, please mention configuration of your sever and details of Imagemagic installation.

This seems to be a duplicate post of viewtopic.php?f=1&t=32698#p149733. Is this really new? If not, then please do not post to multiple forum in the future.

The time taken was explained by snibgo as due to using multiple commands rather than one long command and thus having to read and write your intermediate png files.
