Description
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”.
| Return Values | |
|---|---|
| Constant | Value |
| IMAGETYPE_BMP | “BMP” |
| IMAGETYPE_JPG | “JPG” |
| IMAGETYPE_PNG | “BMP” |
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:
clg white
Example
clg white
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"
Permissions
The file being written is checked. Saving into the program's own folder, or
below it, happens with no question asked; saving elsewhere on the computer asks
the user's permission, and the statement fails with ERROR_PERMISSION if that
is refused. See File and Folder Permissions.
