![]() In order for that to happen, a definition had to be created to tell the computer how many pixels were equivalent to one inch. In other words if you drew a box that was 1 inch square, you would want to see that displayed on the screen. In the early days of graphical drawing it was assumed the user would want to see their drawing full scale. The concern was centered around units and how they are used in Inkscape. Working with paths in the context of vector graphics is rudimentary – so take your time to understand the underlying principle.Last September I began to follow a discussion on pixels in the Inkscape Developer's mailing list. You can access all important tools via the toolbar on the left edge of the window, as well as the path tool and some helpers that conjure up prefabricated forms in the Inkscape graphics. At the top are a few other toolbars next to a classic quick-start bar. ![]() The work area takes up the majority of the Inkscape window, shown as a white sheet. Do not be fooled, however creating vector graphics is quite different from working with pixel images. In fact, some tools in Inkscape have similar functions to their counterparts in other tools. Then, you will find an entry for the vector graphics program – which you can use to get Inkscape on the screen – in the start menu of the respective desktop.Īt first glance, the Inkscape interface very much resembles pixel graphics applications like Gimp. If it has not already been set up during the system installation, you do this easily using the respective package management system the corresponding package is almost always called inkscape. Inkscape, which, like Firefox, Gimp, or LibreOffice, is regarded as one of the crown jewels of free software, can be found in the repositories of all major distributions. It scales easily – on a smartphone screen or a meter-wide projection screen. The line therefore always appears neat and high resolution.īecause a vector graphic describes all elements in this way and also defines the relationship of objects to each other, a complete graphic can be portrayed using mathematical formulae. When representing the graphic, the display program interprets this information and then displays the line accordingly. A vector graphic instruction could therefore read that a black line at the bottom of the image is occupying the entire width. Vector graphics work fundamentally differently than pixel graphics: A vector graphic virtually describes the construction of the image and the ratio of the individual picture elements to each other. The same applies to graphics otherwise, you'll see only a mash of pixels. ![]() Think of a presentation that is supposed to run on a projector with 720p or 1080p resolution: Photos you want to incorporate there must offer at least full-HD resolution. Today, increasingly higher resolutions are easing the problem with digital photos however, the same still applies to digital graphics. The higher the resolution and dpi number, the less a graphics program has to "invent" when projecting and the more the graphic can be scaled 300 dpi is the basic requirement for high-quality printing. The combination of resolution and density determines the context in which an image file can be scaled. The higher the dpi, the finer and sharper the graphic. Digital Resolutionĭigital photos and graphics are not just a specific resolution, the point density, which is specified as the number of dots per inch (dpi), is also important. In this article, I explain the first steps of using Inkscape. However, starting to use this rather complex application is not very easy. In Linux, you can use the Inkscape program to create vector graphics yourself. This problem can be solved using vector graphics. If so, you have stumbled across a fundamental problem of digital graphic processing: Pixel graphics can be shrunk almost arbitrarily, but they can only be enlarged to a certain degree: Where no more material is available in the original photo, the software must "add" pixels, but this only works to a limited extent, and the result is not like the original photo. You may have taken a photo with a digital camera which, at first, seemed sharply printed, but when enlarged seemed blurry and "mushy" in places.
