Video: Polygonal Lasso tool and Quick Mask

In this movie, I'll show you how to use the Polygonal Lasso tool to build the rays that are emanating out of the moon inside the final composition. I'm still working away inside Daytime moon.psd. We have one triangular ray that we've created so far and we're going to create the other ones using the Polygonal Lasso. To get to it, go up to the Lasso tool flyout menu, Click+Hold and choose the Polygonal Lasso tool from the flyout menu. You can also press Shift+L. And then you need to press the Shift key so that you get a little plus sign next to the horned lasso cursor and that tells you that you'll end to the existing selection outline, then click at the center of the image where the guidelines intersect.

Polygonal Lasso tool and Quick Mask

In this movie, I'll show you how to use the Polygonal Lasso tool to build the rays that are emanating out of the moon inside the final composition. I'm still working away inside Daytime moon.psd. We have one triangular ray that we've created so far and we're going to create the other ones using the Polygonal Lasso. To get to it, go up to the Lasso tool flyout menu, Click+Hold and choose the Polygonal Lasso tool from the flyout menu. You can also press Shift+L. And then you need to press the Shift key so that you get a little plus sign next to the horned lasso cursor and that tells you that you'll end to the existing selection outline, then click at the center of the image where the guidelines intersect.

And once you've clicked, you can release the Shift key, you only have to press it right there at that first click point. And notice that I've click the second time out here in the pasteboard. And then at the third point, I can just double-click in order to finish the selection. And then I would Shift+Click again at the center, click out here in the pasteboard, double-click in order to create another ray and so forth. You may find it inconvenient to have to press the Shift key over and over again and that's what these icons are for, up here at the outside of the Options Bar.

They allow you to apply so called Selection Calculations. Now, the first one which is selected by default reads New Selection. So if you click without holding a key, you'll deselect the existing area and start a new selection. However, if you move over to the second icon, notice that it reads Add to Selection. Go ahead and click on it to select it and now you don't have to press the Shift key anymore because your cursor automatically has a plus sign. You can click at the center, click on the pasteboard, double-click, and then click in the center, click out here in the pasteboard, double-click.

And we're keeping it random the whole time, so sometimes you want slim little triangles like so, and other times you want thicker triangles, and you want different amounts of space between each one of these rays and so forth. Now it might be a little tedious watching me create these things, which is why I've gone ahead and saved the selection along with the image. I'm going to load it up by going up to the Select menu and choosing the Load Selection command. And then inside the Load Selection dialog box, if you are working along with me, make sure Document is set to the document you're working inside of, and then make sure Channel is set to half rays.

Now these should all be set this way by default. The Invert check box should also be off and Operation should be set to New Selection. If all that is true, then just go ahead and click OK in order to load up that selection outline. Now notice that I've only selected the top half of the image, and that's because I decided drawing half the rays was enough and I could go ahead and duplicate the selection and rotate it a 180 degrees to create the rest of the rays. But to do that, you have to enter a special mode called the Quick Mask mode.

And you can switch to the Quick Mask mode by clicking on this Edit in Quick Mask Mode icon down here towards the bottom of the toolbox, and notice that it looks like a dotted circle inside of a rectangle. Go ahead and click on it and you see this Rubylith Overlay. And here's what it means, anywhere that you see the red overlay, that's a deselected region of the image. Wherever you don't see the red overlay, is selected. Now I'm going to select the top half for this mask using the Rectangular Marquee tool. Now if you're working along with me, make sure to change the Style Setting from Fixed Size back to Normal so you can draw an unconstrained rectangle.

And then go ahead and select the entire top region of the image, all the way down to the horizontal guideline. Now at this point, we need to rotate the selection using the Free Transform command, and you may have recalled me mentioning that the Free Transform command under the Edit menu has a keyboard shortcut of Ctrl+T or Command+T on the Mac. If you add the Alt key or the Option Key on the Mac, you go ahead and duplicate the selection as well. And so, in order to make this work we have to use the shortcut. And so, I'm going to Escape out of the menu and press Ctrl+Alt+T here on the PC, that would be Command+Option+T on the Mac.

And then, I'll zoom in just a little bit here. Notice that target right there at the center of the selection? I want you to drag it down so that it snaps into alignment with the guide intersection, right there at the bottom handle. And that indicates the center of our rotation. Now I'll right-click inside the image and choose 180 degrees and you'll end up rotating and duplicating those spikes. Now you can press the Enter key or the Return key on a Mac in order to complete the transformation and press Ctrl+D or Command+D on the Mac to deselect the image.

Now we need to convert the mask back into a selection outline and you do that by dropping down to that icon at the bottom of the toolbox once again. Now it says Edit in Standard mode. Go ahead and click on it. And so, the marching ants and the Quick Mask mode are just two different ways to look at the selection outline. And incidentally, you can switch between them from the keyboard by pressing the Q key. So tap the Q key to go to into the Quick Mask mode, tap it again to exit the Quick Mask mode and see the marching ants. And that's how you create a straight -sided selection outline using the Polygonal Lasso tool.

And as you can see, you can make your selection outlines as intricate, not to mention, accurate, as you like.

Q: Where can I learn more about graphic design?
A: Discover more on this topic by visiting graphic design on lynda.com.
Q: When I double click the welcome.psd file included with the exercise files, I get the following error message:

"Some text layers contain fonts that are missing. These layers will need to have the missing fonts replaced before they can be used for vector based output."

Unlike the TIF and JPEG files which display and open correctly, all the icons for PSD files are blank but other than the welcome.psd file, they seem to open correctly without the error message. Is this a problem that I should address (perhaps re-download the files or find the missing fonts)?
A: The TIFF and JPEG files are flat, so they don't contain fonts and the operating system can interpret them (and generate thumbnails) without help from Photoshop. The PSD files have two issues:

First, they may contain editable text complete with font info. The files are designed with fonts that ship with Photoshop, so you don't get error messages, but Adobe sells some versions of Photoshop without fonts. This may be your issue.

Second, the PSD files contain no flat previews. This makes for smaller files, but it means the operating system, Mac or Windows, cannot generate previews. That won't effect your experience in Photoshop, but it does mean you can't see the file until you open it.
