aThe file size of vector data structures are smaller than those of raster images because a raster image needs to store the digital number of all the pixels while only point coordinates are stored in vector data. For example, let us consider an image consisting of large homogeneous regions as ...
This allows testing of drawing accuracy and performance for both the native, raster, and OpenGL paint engines. See the Qt SVG module documentation for more information about SVG and Qt's SVG classes. Example project @ code.qt.ioV-Play got rebranded to Felgo! See why and the Felgo roadmap...

You can not change the logical pixel resolution of a canvas (canvas.width, canvas.height) with CSS. Even if you could, you would still have to run some JS to generate a new raster image with a different number of pixels. Contributor greggman commented Jun 19, 2020 I'm not asking for...
