# Raster Images [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [User Guide](Help%20System/GSTARCAD/2022/User%20Guide/(User%20Guide).md) Raster images consist of a rectangular grid of small squares or dots known as pixels. Raster images can be added in a drawing by inserting image files or pasting as OLE. Raster images can be copied, moved, and support the follow formats: BMP (.bmp, .dib, .rle) CALS-I(.gp4, .mil, .rst, .cg4, .cal) JPEG (.jpg, .jpeg) PCX (.pcx) PNG (.png) TIFF (.tif or .tiff) [Overview of Raster Images](Help%20System/GSTARCAD/2022/User%20Guide/Raster%20Images/Overview%20of%20Raster%20Images.md) [Attach and Detach Raster Images](Help%20System/GSTARCAD/2022/User%20Guide/Raster%20Images/Attach%20and%20Detach%20Raster%20Images.md) A raster image file can be attached and detached to a drawing file. Once an image is detached, all instances of the image are removed from the drawing. [Show and Hide Raster Image Boundaries](Help%20System/GSTARCAD/2022/User%20Guide/Raster%20Images/Show%20and%20Hide%20Raster%20Image%20Boundaries.md) You can control whether the clipping boundaries of a raster image are displayed or hidden by performing the command IMAGEFRAME and setting up the values 1 or 2\. [Clip Raster Images](Help%20System/GSTARCAD/2022/User%20Guide/Raster%20Images/Clip%20Raster%20Images.md) If you want to display only parts of images, you can clip the images by IMAGECLIP with polygonal, rectangular or closed polyline. [Change Raster Image Brightness, Contrast and Fade](Help%20System/GSTARCAD/2022/User%20Guide/Raster%20Images/Change%20Raster%20Image%20Brightness-%20Contrast-%20and%20Fade.md) You can change several display properties of raster images, such as brightness, contrast, fade and transparency.
