<td><p>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 <b>draw()</b> or within mouse and key events such as <b>mousePressed()</b> and <b>
|
|
keyPressed()</b>. If <b>saveFrame()</b> is called without parameters, it will save the files as screen-0000.tif, screen-0001.tif, etc.
|
|
It is possible to specify the name of the sequence with the <b>filename</b> parameter and make the choice of saving TIFF, TARGA, PNG, or JPEG files with the <b>ext</b> parameter.
|
|
These image sequences can be loaded into programs such as Apple's QuickTime software and made into movies.
|
|
These files are saved to the sketch's folder, which may be opened by selecting "Show sketch folder" from the "Sketch" menu. </p>
|
|
<p>All images saved from the main drawing window will be opaque. To save images without a background, use <b>createGraphics()</b>.</p></td>
