| Description |
|
Updates the display window with the current data from pixels[]. It's possible to only update a portion of the window by specifying a smaller rectangle with the x1, y1, width, height parameters. The imageMode() function changes the way the parameters work. For example, imageMode(CENTER) will change x and y to define the center of the image. A call to imageMode(CORNERS) will change the width and height parameters to define the x and y coordinates of the opposite corner of the image. |
