Field Summary

boolean	done
boolean	doSavePreview
boolean	isTiling

Constructor Summary

TileSaver(processing.core.PApplet _p)

Method Summary

boolean	checkStatus() Returns true if tiling is in progress.
int	getMaxTiles(int width)
void	init(java.lang.String _filename) If init() is called without specifying number of tiles, getMaxTiles() will be called to estimate number of tiles according to free memory.
void	init(java.lang.String _filename, int _num) Initialize using a filename to output to and number of tiles to use.
void	post() post() handles tile update and image saving.
void	pre() pre() handles initialization of each frame.
void	restoreCamera() Used to restore camera once tiling is done.
void	setSaveType(java.lang.String extension) set filetype, default is TGA. pass a valid image extension as parameter.
void	setupCamera() Used to set up camera correctly for the current tile.
void	tileFinish() tileFinish() handles the saving of the tiled image.
void	tileInc() Increment tile coordinates.

Method Detail

init

public void init(java.lang.String _filename)

If init() is called without specifying number of tiles, getMaxTiles() will be called to estimate number of tiles according to free memory.

init

public void init(java.lang.String _filename,
                 int _num)

Initialize using a filename to output to and number of tiles to use.

setSaveType

public void setSaveType(java.lang.String extension)

set filetype, default is TGA. pass a valid image extension as parameter.

pre

public void pre()

pre() handles initialization of each frame. It should be called in draw() before any drawing occurs.

post

public void post()

post() handles tile update and image saving. It should be called at the very end of draw(), after any drawing.

checkStatus

public boolean checkStatus()

Returns true if tiling is in progress.

tileFinish

public void tileFinish()

tileFinish() handles the saving of the tiled image.

tileInc

public void tileInc()

Increment tile coordinates.

setupCamera

public void setupCamera()

Used to set up camera correctly for the current tile.

restoreCamera

public void restoreCamera()

Used to restore camera once tiling is done.

getMaxTiles

public int getMaxTiles(int width)
