Beschreibung

Bitmap oder Rastergrafik sind 2D-Bilder, die Sammlungen von Pixeln in verschiedenen Farbschattierungen enthalten. Zusammen präsentieren Tausende oder Millionen von Pixeln dem Betrachter eine Abbildung oder eine Farbaufnahme.

Bitmaps are different from vector images like SVG, in that their pixel resolution is defined at their creation. This means that a picture stored as a bitmap cannot be made bigger or smaller without losing visual details.

Bitmap images are usually compressed to reduce their file size. This results in common file types such as PNG, TIFF, and JPEG, which all use different types of compression.

How to use

FreeCAD can import bitmap images using the Image Workbench. Other workbenches can also insert bitmaps, like the TechDraw Image tool from the TechDraw Workbench.
