Example showing effect of vector graphics versus raster graphics. The original vector-based illustration is at the left. The upper-right image illustrates magnification of 7x as a vector graphic. The lower-right illustrates the same magnification as a raster (bitmap) graphic. Raster images are ...
Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
Inverse Graphics: It facilitates the reconstruction of vector graphics from raster images, which is useful in applications like image vectorization and graphic design. Learning-Based Methods: Differentiable rasterization can be integrated into neural networks, enabling end-to-end training for tasks that ...

the graphic card's clock may be slowed down by the driver during program execution ( On Linux when OpenGL application starts in adaptive mode, clock should work as fast as possible, but after one minute of program execution, the clock ...
In the initial stage of research on variable resolution maps, the author conducted a very simple experiment that consisted of creating such a map from a mosaic of raster maps in various scales. Such a map may be created easily by dividing the area into classes and assigning them a raster ma...
geoinformation algorithms; centerline of a polygon; centerline of a river; watercourse modeling1. Introduction Inland bodies of water are represented by raster or vector data in Geographic Information System (GIS) applications. Raster data are acquired from satellite images. Datasets describing inland ...
