Schmitz The [1]Pixelmator image editing app has been updated to version 3.1 (nicknamed Marble) with a couple of improvements aimed at the new Mac Pro. It adds support for 16-bit per channel images, and it's able to simultaneously utilize the Mac Pro's dual graphics processors to accelerate composition rendering for faster and more responsive performance (see this [2]blog post for more). Pixelmator also adds MILK Print on Demand as its on-demand printing partner, enabling you to order prints (as well as notecards, posters, and more). The update also brings a bevy of layer styles improvements, returns a number of effects (including Pointillize, Pixelize, Mandala, Concert, and more), improves the stability of the effects rope, improves support for RAW image files, ensures text stays visible on grouped text layers that are duplicated, and banishes the 'Low disk space' message when it's clear that your computer has ample storage space.
