PGraphics clear() is undefined!

in General Discussion • Other • 7 months ago

In the reference there is a page, that refers to a clear() function for PGraphics. But when I try to use it on a simple PGraphics instance, it says that "The function clear() does not exist." My problem is as simple as that.

If this function does turnout to be nonexistent, then what would an alternative be? I've tried the things that were mentioned in this post.

Thanks in advance!

At the top of clear() reference, I've spotted this:

This reference is for Processing 2.0+.
If you have a previous version, use the reference included with your software.

For fix, you can always use background(0, 0)!

Or this one:

loadPixels();
for (int i = pixels.length; i != 0; pixels[--i] = 0);
updatePixels();

PGraphics p = createGraphics(100, 100, JAVA2D);
p.clear();

works in 2.0b8.
Can't say the doc isn't up to date (for this one, at least!).
And, indeed, it is the same as background(0, 0, 0, 0);
