It is important to decide how exact you want to be and what you are trying to achieve. The best way to decide the crop area is to use the selection tools. This is time consuming and error prone, but there are several other ways. Since the shape is not defined precisely by any geometric pattern you must trace along the edge. It gets a bit more complicated when you want to cut out the person on the picture or, as I thought, the panda. You can use any regular shape to do the same, this is not as easy as cutting a straight line. This is the simplest method so move on to the next level. When you have your selection, find ‘Crop to Selection’ in the ‘image’ drop-down menu. You do this with the Tool Options dialog. You also have the option to choose a specific aspect ratio of you final picture. Simply choose the selection tool with the letter r choose your space and mark. You can cut the parts you have selected the most straightforward case is cutting a square. In this article, you will see a few ways to crop a picture with GIMP. In these cases, you can paint over or cut out parts of the picture. Perhaps you want your motive to have another background or you need to remove details that are irrelevant or sensitive. Now you will need to save the image otherwise the changes will not take effect next time you open the image.One of the most important jobs you can do in GIMP, is cropping the parts you want. If you use this tool GIMP will try and 'find the edges' of an object within the image or selected area.
If you had an area selected with one of these tools and then chose the Crop tool, and then clicked the crop tool on the image, and then clicked on 'From Selection' then the crop tool would choose the pre-selected area. If you had already selected an area using one of the select tools: This button doesn't do much unless you already have selected an area of the image before you start dragging the crop tool around. In the case of a 4:3 Aspect Ratio the Height is 75% of the Width. The first number (in this case '4') relates to the Width and the second number relates to the Height. Most digital cameras use the Aspect Ratio of 4:3.
#HOW TO CROP IN GIMP PC#
pc - pica (this a unit of measure in typography - there are 12 points in a pica, and a pica is 4.233 mm)Īspect Ratio relates to the ratio (mathematical comparison) of the height and width.pt - points (in typography, a point is the smallest unit and is equivalent to 0.3527 mm ).% - height and width will be displayed in a percentage of the original size.You can click on this box and see a variety of options : This relates to the unit of measurement for the Height and Width. You will also see that in the above example there is a 'px' box: Usually you judge the starting point and size of the crop by eye.
This information isn't really that useful unless you need to cut the image to a specific size. The Height and Width boxes tell you the height and width of the crop. Essentially the number in the Origin Y relates to the crop point closest to the top and the Origin X relates to the point of the crop closest to the left of the image. Origin X is the point on the X axis where the crop will start and Origin Y is the point on the Y axis where the crop will start :Įxcept that the details shown in the crop box aren't very intuitive. The crop window tells you where the crop points start on the X and Y axis. This window displays all the cropping information. Now, in the process you would have seen this window pop up: In the process you will see a box appear and move as you move the mouse: First click on the image where you wish the cut to start and drag it to where you wish it to stop. Now we can simply drag the cropping tool over the image. We want to focus on just one tool, not surprisingly called the 'cropping tool' :Ĭlick on this tool and you will see the mouse pointer change to look like the 'knife' icon displayed in the ToolBar. So, the first thing you want to do is look to the GIMP 'ToolBar': Lets say we want to have a close up of Ntsikelelo without all the messy desk to the right, in other words we want to cut out the greyed areas you see here: So, lets assume you have an image open in front of you. Thankfully with digital images it is now all a whole lot easier. They would do this using a number of techniques and some of them were quite tricky. Photographers used to choose which part of an image would show when they exposed the image on photographic paper. The term comes from the photographic crafts. Sometimes you might have an image that needs a little bit 'cut off' or trimming.
