addImageback to summary
public TexturePacker.Rect addImage(File file, String rootPath)

The image won't be kept in-memory during packing if Settings#limitMemory is true.

Parameters
rootPath:String

Used to strip the root directory prefix from image file names, can be null.

private int[] getPads(BufferedImage image, String name, int[] splits)

Returns the pads, or null if the image had no pads or the pads match the splits. Pads are an int[4] that has left, right, top, bottom.

getSplitPointback to summary
private static int getSplitPoint(WritableRaster raster, String name, int startX, int startY, boolean startPoint, boolean xAxis)

Hunts for the start or end of a sequence of split pixels. Begins searching at (startX, startY) then follows along the x or y axis (depending on value of xAxis) for the first non-transparent pixel if startPoint is true, or the first transparent pixel if startPoint is false. Returns 0 if none found, as 0 is considered an invalid split point being in the outer border which will be stripped.

getSplitsback to summary
private int[] getSplits(BufferedImage image, String name)

Returns the splits, or null if the image had no splits or the splits were only a single region. Splits are an int[4] that has left, right, top, bottom.
