Make sure you have no selections by pressing Command-D (or choosingDeselect from the Select menu), and then choose among the options on the AlignLinked submenu (under the Layer menu see Figure 2-6). If you want to align morethan two layers, link all of them. Page-layout programs have offeredalignment features for years, but this capability first appeared in Photoshop 5,and it's a godsend for anyone who really cares about precision in theirimages (we find it particularly useful when building images for the Web).Here's how you can align objects on two layers.Ĭhoose which layer you want "locked"that is, which onestays put while the other layer movesby selecting it in the Layerspalette.Ĭlick in the second column of the Layers palette next to the layer youwant to move (a link icon should appear next to it). If you don't like these settings,change them in the Guides and Grid Preferences dialog box (you can select thisfrom the Preferences submenu), or just double-click on any guide with the Movetool (or Command-double-click with any other tool).Īlignment and distribution. Grid linesare, by default, set one inch apart. Hide/Show All Extras (grids, guides, etc.)Ĭhanging Guides and Grids. (If you don't think in inches, you canchange the default measurement system see "Switch Units," later inthis chapter.) You can always move a guide with the Move tool (don't forgetyou can always get the Move tool temporarily by holding down the Command key).Table 2-1 lists a number of grids and guides keystrokes that can help you usethese features effortlessly. Or, if you care about specific placement, youcan either carefully watch the measurements on the Info palette as you drag, orselect New Guide from the View menu. You can add a guide to a page by dragging it out from eitherthe horizontal or vertical ruler. Wherever you move your cursor, faint tickmarks appear in the rulers, showing you exactly where you are (you can alsofollow the coordinates on the Info palette). The ruler is the simplest: you canhide or show it by pressing Command-R. Moving pixels is all very well and good, but where are you going to move themto? If you need to place pixels with precision, you should use the ruler,guides, grids, and the alignment features. If the two images have the same pixeldimensions, the Shift key "pin-registers" itthe layer orselection falls in exactly the same place as it was in the original document. However, if you hold down the Shift key, Photoshop centersthe layer or selection in the new image. Whenyou let go of the mouse button, the selection is placed into the image rightwhere you dropped it. In the last tip we talked abouthow you can drag and drop a selection or layer from one image into another. This is a great speedup,especially when working with heavily feathered selections. When you do have something selected, you don't have to worryabout positioning the cursor before you click and drag. With the Move tool, you can move an entire layer around without selectinganything. When you move or copy selected pixels with the Move tool, you get a floatingselection (sort of like a temporary layer that disappears when you deselect).While the selection is still floating, you can use the Fade command (in theFilter menu) to change its opacity or blend mode. Note that you can hold down the Option key while you drag tocopy the pixels as you move them (moving a duplicate of the pixels). Fortunately, no matter what tool isselected, you can always temporarily get the Move tool simply by holding downthe Command key. If you want the pixels tomove as well, you have to use the Move tool. If you simply make a selection, then drag it with one of the selection tools,you move the selection boundary but not its contents.
