Name
saveFrame()
Description
Saves a numbered sequence of images, one image each time the function is
run. To save an image that is identical to the display window, run the
function at the end of draw() or within mouse and key events such as
mousePressed() and keyPressed(). Use the Movie Maker program
in the Tools menu to combine these images to a movie.
If saveFrame() is used without parameters, it will save files as
screen-0000.tif, screen-0001.tif, and so on. You can specify the name of
the sequence with the filename parameter, including hash marks
(####), which will be replaced by the current frameCount value. (The
number of hash marks is used to determine how many digits to include in the
file names.) Append a file extension, to indicate the file format to be
used: either TIFF (.tif), TARGA (.tga), JPEG (.jpg), or PNG (.png). Image
files are saved to the sketch's folder, which may be opened by selecting
"Show Sketch Folder" from the "Sketch" menu.
Alternatively, the files can be saved to any location on the computer by
using an absolute path (something that starts with / on Unix and Linux, or
a drive letter on Windows).
All images saved from the main drawing window will be opaque. To save
images without a background, use createGraphics().
Examples
int x = 0; void draw() { background(204); if (x < 100) { line(x, 0, x, 100); x = x + 1; } else { noLoop(); } // Saves each frame as line-000001.png, line-000002.png, etc. saveFrame("line-######.png"); }int x = 0; void draw() { background(204); if (x < 100) { line(x, 0, x, 100); x = x + 1; } else { noLoop(); } // Saves each frame as screen-0001.tif, screen-0002.tif, etc. saveFrame(); }
