Help test and triage bugs in the bugtracker.If this option is checked, shear handles remain on this edge. If this option is unchecked (default), you may move away from this edge. Shear: normally, to shear the layer, you drag the corresponding icon along a layer edge. Alexander Prokoudine - /u/alexlg ( LGW Founder) ( patreon) Ways to Assist GIMP When this option is checked, rotation goes by 15 steps.YouTube Channel spamming will not be tolerated.These are minor and subtle changes, but you can see how Guido’s teeth, tongue and eyes are now more sharply defined.CSS help provided by /u/Cheesydude All about the GNU Image Manipulation Program I used the settings: Radius: 5, Amount: 0.5, Threshold: 10. In a nutshell, if you set a high threshold, your edges will be softer, whereas a low threshold will make your edges harder. And the Threshold slider allows you to set the hardness of your edges. The Amount slider lets you set how strongly the unsharp mask will be applied. The Radius slider lets you set how many pixels on either side of an edge the unsharp mask will affect. You have three options in this dialog: Radius, Amount and Threshold. It will bring up a dialog box like the one pictured below. You’ll find it under Filters: Enhance: Unsharp Mask. Lastly, we’re going to fix the fuzziness of the focus using the Unsharp Mask filter. When you’re happy with the size of your square, hit Enter and your image will instantly crop. Those are handles and you can use them to resize your cropping area. To rotate the entire color selection, you will always have to click and move the Left button of the mouse, but inside the radius. Notice that this square has smaller squares in the corners. To use the Crop tool, simply click and drag on your image. You will also see options to set the position of your crop and specify an exact size. That means the width and the height will be equal no matter how large or small I make my square. Or, I can check the ‘Fixed’ box and ‘Aspect Ratio’ from the drop-down menu and enter 1:1. I could drag the crop tool around until I get what looks more or less like a square. I’m going to use my image as an avatar, so I want it to be a square. Select the Crop tool either by clicking its icon in the toolbox or using the keyboard shortcut SHIFT+C.īefore we use the Crop tool, take a look at the tool options dialog. But when we applied a rotation, we skewed the image out of alignment with the canvas. If you rotate text, don't rotate as a raster layer instead do: Layer>Text to path Rotate the path Select>From pah and bucket-fill on a new layer The default interpolation method is set in Edit>Preferences>Tool options>Scaling deleted 5 yr. When we first opened our image, it was aligned with the GIMP canvas. But what’s that weird checkerboard that appeared around the corners? That’s the transparent background layer. Guido now looks like an upstanding Python, not a slouchy snake. Upon hitting return, I got the following results: I used the slider and found a value of -2.77 to be just right. In the Rotate dialog, you have the option of entering an angle value or of using a slider to adjust the rotation of your image. If you selected it from the toolbox, click on your image to open the Rotate dialog. If you use the keyboard shortcut, the Rotate dialog will automatically pop-up. Select the rotation tool, either in the tool box, as pictured below, or by using using the keyboard shortcut SHIFT+R. I’m going to apply an unsharp mask to correct it. If you look closely, you’ll see that this photograph is out of focus.I want to highlight Guido’s head and not the background or the table.You can see that Guido is listing to the right a bit I’m going to rotate the image so the background is more or less perpendicular to the picture plane.There are three things I want to do to this photograph: The changes we make will be very subtle but will enhance it considerably. That’s why this is the perfect photo for us to practice on. At first glance, you might think there’s nothing wrong.
I’m going to use this picture I took of Guido. In this tutorial I will go over three very easy and useful tools in GIMP you can use to perk up your pics: rotate, crop and the unsharp mask.įirst we need an image. But even Ansel Adams missed the mark on occasion. I’m sure you’re an accomplished photographer.
