loadImage

public static processing.core.PImage loadImage(processing.core.PApplet app,
                               java.lang.String filename)

Load a single bitmap file return a reference to the PImage created.

Parameters:

app -

filename -

Returns:

null if the file does not exist else the PImage object

loadImage

public static processing.core.PImage[] loadImage(processing.core.PApplet app,
                                 java.lang.String[] filename)

Load images from multiple files

Parameters:

app -

filename - an array of filenames

Returns:

an array of images

makeTiles2D

public static processing.core.PImage[][] makeTiles2D(processing.core.PApplet app,
                                     processing.core.PImage img,
                                     int nCols,
                                     int nRows)

Make multiple images from a given image. This method creates a 2D array (size [nCols, nRows] ) of PImage objects.

Parameters:

app -

img - the tiled image

nCols - number of tiles across

nRows - number of tiles down

Returns:

a 2D array of images (tiles)

makeTiles1D

public static processing.core.PImage[] makeTiles1D(processing.core.PApplet app,
                                   processing.core.PImage img,

                                   int nRows)

Make multiple images from a given image. This method creates a 1D array of PImage objects. The order is left-right and top-down.

Parameters:

app -

img - the tiled image

nCols - number of tiles across

nRows - number of tiles down

Returns:

a 1D array of images (tiles)
