imgsave ( filename, type )
Save the current Graphics Output Window to an image file.
By default the image is saved as a Portable Networks Graphics (PNG) file. You may optionally specify the image type as a “BMP”, “JPG”, “JPEG”, or “PNG”.
Sometimes images will be saved with “black” filling where the screen was undrawn. This is caused by the CLG statement setting the background to the color “clear” (transparent). When the image is saved the transparency is changed to black. Change your CLG statement to the following:
color white rect 0, 0, graphwidth, graphheight
color white rect 0, 0, graphwidth, graphheight for t = 0 to 100 color rand()*256, rand()* 256, rand()*256 rect rand()*graphwidth, rand()*graphheight,rand()*graphwidth, rand()*graphheight next t imgsave "testimgsave1.png" imgsave "testimgsave2.jpg", "jpg"
