Methods

Modifier and Type	Method and Description
void	flip(boolean x, boolean y) Flips the region, adjusting the offset so the image appears to be flip as if no whitespace has been removed for packing.
float	getRotatedPackedHeight() Returns the packed height considering the rotate value, if it is true then it returns the packedWidth, otherwise it returns the packedHeight.
float	getRotatedPackedWidth() Returns the packed width considering the rotate value, if it is true then it returns the packedHeight, otherwise it returns the packedWidth.

Field Detail

index

public int index

The number at the end of the original image file name, or -1 if none.

When sprites are packed, if the original file name ends with a number, it is stored as the index and is not considered as part of the sprite's name. This is useful for keeping animation frames in order.
