![]() ![]() So, it’s possible to recover the data after the file size is reduced. ![]() It means that no data is lost during the compression process. One strong advantage of PNG files is that they use a lossless compression algorithm. Is compression the same as resizing a PNG image? This makes the format resolution independent. Rather than using pixel information, the image is rendered from XML elements and attributes similar to a webpage. When we finally learn about SVG, you’ll realize that it’s a vector graphics format. That’s why methods such as resampling are applied when enlarging PNG images to add new information to the image during resizing. Therefore, the tiny pixels become more visible, causing the image to lose its clarity. When you enlarge the image beyond its initial dimensions, no new information is added. Raster-type images are resolution-dependent as they have a fixed number of pixels and hence a defined amount of information. It contains the digital numeric color data that defines how the computer should display that tiny square. Essentially, the image is constituted of tiny rectangular pixels organized in a two-dimensional grid with columns and rows.Ī pixel is like a single dot of color on a canvas. It falls in the same class as JPEG as it’s a raster image file. PNG in full stands for Portable Network Graphic. On that note, let’s dive into the two formats to discover how and when to use them. You should be thoroughly intrigued by now. The image above has some lines of code missing (laughs mischievously). After modifying the code of the original svg picture of a pineapple Know what this means? You can perform some fun and juvenile tricks.įor instance, you can view the code with a text editor such as Notepad and delete some lines of code. It’s generated from a piece of code in XML format. The image is no longer represented by tiny pixels (small rectangles) occupying fixed points on a grid. It resembles an artwork rather than a realistic photograph.Ī drastic transformation has happened under the hood.The image looks simplified with fewer details.Here is a picture of a pineapple: How our png pineapple picture changes after converting it to svg ![]() To kick off this blog in style, there’s something curious about converting a PNG image to SVG format (vectorizing). ![]()
