Rasterizing a layer in Krita converts vector or generated content into a pixel-based image. This process transforms elements like text, vector shapes, or filter masks into a static collection of pixels, similar to a photograph. For example, text created as a vector object can be made editable on a pixel level by rasterizing it; subsequently, individual pixels within the text can be altered using painting tools.
Rasterization allows for advanced pixel-level editing and the application of effects that are incompatible with vector layers. It ensures consistency in appearance across different systems and software, as the visual data is defined by the specific pixel arrangement rather than by mathematical definitions of shapes. In the earlier days of digital art, rasterization was a more common final step due to limitations in displaying and printing vector graphics, although modern software handles vector graphics more effectively. However, the practice persists for achieving specific artistic effects or preparing an image for specific workflows.
