Exporting Print Ready Images from Jitter (guide)
Hi All,
I wrote this brief guide about exporting print-ready images from my Fragment:Flow app (built with Max/Jitter). Rob @ C74 suggested that it would be a useful thing to post here since the general method is applicable to anyone using Jitter for print.
The method involves working out the required resolution necessary for a given DPI and print size and exporting at that size. What I call “texture dimensions/resolution” in my app is basically the rendering resolution defined by the dim attribute of your various jit.gl/jitter objects.
My software uses a jit.matrix object to capture and export a single frame using the “exportimage” message. While Max allows you to globally set the DPI of exported images from a set list via the preferences menu, it is possible to target any given DPI and print-size by calculating the required resolution using the method described and then adjusting the resulting image in an image editing app to reflect the correct values. If your calculations and export settings were correct then the image will not be resized at all, so you’re effectively just correcting the meta-data.
Obviously, the main limitation is your hardware when working at these resolutions, but it is possible to produce very high quality images suitable for print with this approach given a sufficiently powerful machine.
Some of this is specific to my app, but I hope that the general approach proves useful to someone:
