Demo of high-res tiled image output: KugelTiled04 res demo
Update: I’ve finally found the time to write a proper class for this tiling technique. Have a look at aTileSaver.pde.
I’ve been able to generate huge raster files for print use from Processing, using the tiling trick first outlined on the Processing forums by user “surelyyoujest”. Using his code as a base, I got it working with OpenGL and proceeded to output some gigantic files. A quick hack using PImage allowed me to stitch the resulting tiles together in one huge image, which was then saved as a Targa file.
See the picture above for a demo. When viewed at its original size, the left half of this image shows the full picture at 10% (original res 10240 x 7680 px). The right half shows the whited-out section of the left image at 100%. The resolution is staggering.
This should clear the way for doing huge prints, without not having to worry about PDFs not showing 3D correctly (see previous post). I will post sample code for tile-based rendering and stitching as a library when I have time.
Mmmm, that’s fantastic. I’ve been having some of my digital art printed on canvas. The results look fantastic. Can’t wait to have some processing-generated stuff to add.
Any chance you could post this code? I’d be really interested!
Sorry, haven’t had time to put together a library. For now I have posted the image stitching code. It’s not so useful without the generating code, but you can look at surelyyoujest’s post for the original example I based my code on.
Hello,
i didn’t find your image stitching code on webside. Please can you post me your image stitching code ? Thank You
Here is the original stitching code. My apologies about the lack of a search function on the blog, I keep meaning to add it…
I created a tool too to merge multiple tiles into one big image (using dotnet framework, so only for windows). I tried it to create an 20.000×20.000px image and within 1minute it is ready. It doesn’t scale anything so the orginal pixels keep intact. It also works with transparent PNG files. So if anyone is interrested, you can download it for free at http://tiler.stroep.nl/.
