Import pictures: 

Picture size.- The displayed image size will depend on the size that had when it was saved. If it is necessary, modify the picture size before loading the image (for example, you can use windows Paint, Adobe Photoshop,… ). You will be able to load BMP maps generated by AutoCad.

Scale command.- Bitmaps and scanned maps must be loaded into memory and then adapted to the program scale (we will make use of the Scale command). The X-Axis width (meters) in the program window can be easily changed to be able to compare both images (simulation results and background maps). Then, the X-Axis width (in meters) of the imported map and the X-Axis width (in meters) of the program window match together. The imported images are not stored physically in the simulation process. Terrain elevations (represented on the imported map) don’t interact in the simulation process. We haven't the possibility to zoom an imported map with the Zoom command. This command only acts in the calculation process. If it is necessary, zoom the map before loading the image.

Zoom command.- We have the possibility to zoom a part of the program window with the Zoom command. However, we won't be able to enlarge background pictures with this command. If it is necessary, zoom the map before loading the background image. This command only acts in the calculation process. This way, we can place a point source in a side of the computer screen and we can calculate the concentrations in another different detailed region.

Export results: 

With the Export Picture command you will be able to export images and pictures (BMP files). These images will contain the background picture and the simulation results. Many programs, computer applications and word processors (AutoCad, 3d Studio, ArcView, MS Word,...) import BMP files. You will be able to load images generated by CUSTIC.
