You can also edit the advanced features to change the resolution, and other information I won’t talk about here. A summary tells you that the image resolution is 72 dpi (or “dots per inch”-I’ll talk about this more in a moment). You are asked to enter the image size this information is expressed in pixels by default. Figure 1: The GIMP’s window in which you enter the data to create a new image Open the GIMP and create a new image typing Ctrl + n (that means “hold the ‘Ctrl’ key and type ‘n’”) or by choosing New from the File menu. You can also read more on image formats in. Keep in mind that you can usually open a vector image with the GIMP, which will rasterize the input image before showing it. In this article I’ll focus on raster images, and I’ll explain how to resize them with the GIMP. However, vector images can’t efficiently store complex images such as photographs. The advantage of a vector image over the raster is that it can be scaled (in or out) without loss of quality. The resolution indicates how close each pixel is to the others They are usually used to store technical drawings, plots and camera-ready documents. Examples of such formats are SVG (Scalable Vector Graphics) and EPS (Encapsulated PostScript). You also have vector images, where the represented scene is not a matrix of pixels, but is instead described by formulas instead. acoustic images, where colors represent the acoustic reflectance.thermal images, where colors represent temperatures.range images, where colors represent the distance between the object and the sensor (usually white pixels represent surfaces that are nearer to the observer and black ones represent surfaces that are the furthest away).There are other types of raster images, such as: These images are commonly known as intensity images. Each matrix entry is called a pixel (picture element) and represents a color (also called light frequency). The most common formats, such as TIFF (Tagged Image File Format), JPEG (Joint Photographic Experts Group), PNG (Portable Network Graphics), are defined raster formats, as they represent the image as a matrix. Each of them provide common or unique features. There are plenty of digital image formats out there. This is a way for me to celebrate 10 years since I started studying digital image processing! Fundamentals In this article I will explain how to resize images. One of the operations people fail most commonly is resizing an image. Image processing tools are so common that users often process images by trial and error, without really knowing what they are doing. Processing digital images is a very common task today.
