You can capture an image if it cannot be saved in the usual way, or if you want to preserve a specific display for later use.
An image capture is like a photograph of the displayed image on your screen. It is particularly useful when you want to prepare images for a presentation or a report. For example, you can capture several displays of satellite data with different color maps. Then you can edit these static images with regular Autodesk tools, and save them in a simpler format such as JPEG or TIFF.
The transparency setting in the source image is preserved in the capture. For complex images from digital elevation models (DEM) or multispectral data, the capture is simplified to a true color image with an Image Adjust color map.
When used with AutoCAD Map 3D toolset, AutoCAD Raster Design toolset can capture data from a layer in Display Manager, which can include Feature Data Objects (FDO) and other imported data. In this type of capture, you have several options for the capture, such as capturing the stylized display or the source data, selecting the capture area, resolution, and type of coordinate transformation, if applicable.
