Tiling/Montaging Huge Images

Platform: Ubuntu 16 ImageMagick Version: 6.7.8-9 I have several large images i need to turn into one gigantic image. Currently i've been testing the montage command with 4x 40,000 x 40,000 Images tiles in a 2x2 grid (so resulting output is 80,000px square) using the command: montage image1.jpg image...

Re: Compositing thousands of images

Thank you - that was indeed the problem! After some more testing i've found there is one aspect that is killing the performance on large images, and that is the -repage [X]x[Y] part. In tracking this down i created a transparent image and saved it to disk using this call: time convert -size 10000x10...

Re: Compositing thousands of images

Apologies for the slow update and thank you again to everyone for your suggestion. I've got this up and running in a multi-threaded fashion that processes a part of the final image, saves it, and then (as a seperate step once this phase completes) assembles all these images into one final big image....

Re: Compositing thousands of images

Thank you - that worked nicely and was very easy to implement! The only challenge i have is that some of the images i'll be creating involve an insane number of these smaller images (250,000 to be exact) and while this new code does work it takes a rather long time. I see the process of parsing the ...

Re: Compositing thousands of images

Thank you both for your answers - much appreciated! Geemack - the small images are picked at random by a completely seperate script that generates the coordinates txt file, and currently i have it returning the full path to the image as part of each line, e.g.: /var/www/html/small_images/small_one.p...

IM Version: 6.9.7-4 Q16 x86_64 OS: Ubuntu Script type: Bash Script Via a Bash script i'm reading in coordinates (X:Y) line by line from a txt file (which has several thousand lines), and then using them to position one of five small (30x30) images at those coordinates on a canvas, and then saving th...

Re: Recolor Image and maintain shading

Thank you both again for your time and help - I ended up changing the image i was using to have more neutral colors, and then added additional code to look at the relative values of the RGB color we were replacing to. Via this i then used a variation of: -colorspace HCL -channel R -evaluate set 75% ...

Re: Recolor Image and maintain shading

Thank you both so much - this is brilliant! Just one more aspect if you don't mind, is there a way to 'lighten' the replaced color so it appears closer to the replaced color (rgb(239,70,36))? Forgive me if this explanation is lacking, but essentially what I am doing is recoloring this image, sizing ...

Hi, i'm using IM version 6.8.9-9 on Ubuntu Linux and am attempting to recolorize this image of a fabric tuft: http://kdassets.com/pile_resized.png By recolorize i mean that i want to change the blue and green areas to a different color but maintain the difference that currently exists (e.g. there ar...
