addRegion method
Adds a new sub-texture region to the atlas using the provided name, region and optional frame and rotation values.
The name
parameter is a String representing the name of the sub-texture
region.
The region
parameter is a GRect object representing the rectangular
region of the sub-texture in the atlas texture.
The frame
parameter is an optional GRect object representing the
rectangular region of the sub-texture frame, which is the area of the
texture used in rendering. If not provided, the entire region
area will
be used as the frame.
The rotated
parameter is an optional boolean value representing whether
the sub-texture region should be rotated. If set to true, the sub-texture
will be rendered at a 90-degree angle from its original orientation.
Implementation
void addRegion(
String? name,
GRect region, [
GRect? frame,
bool rotated = false,
]) {
addSubTexture(
name,
GSubTexture(
_atlasTexture!,
region: region,
frame: frame,
rotated: rotated,
));
