The 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 utilize the Mac Pro’s dual graphics processors simultaneously to accelerate composition rendering for faster and more responsive performance (see this 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 adds a bevy of layer styles improvements, brings back 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 that 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. ($29.99 new from the Mac App Store, free update, 36.7 MB, release notes)
Extend Mac OS X's Screenshots
Mac OS X has a variety of built in screenshot methods. Here's a look at a few that offer more versatility than the basic full-screen capture (Command-Shift-3):
• Press Command-Shift-4 and you'll get a crosshair cursor with which you can drag to select and capture a certain area of the screen.
• Press Command-Shift-4-Space to select the entire window that the cursor is over, clicking on the window will then capture it. The resulting screenshot will even get a nice drop shadow.
• Hold down the Space bar after dragging out a selection window to move your selection rectangle around on the screen.
• Hold down Shift after dragging out a selection to constrain the selection in either horizontal or vertical orientation, depending on the direction of your drag.
• Hold down Option after dragging out a selection to expand the selection window around a center point.
