Detailed Description

Generates texture atlases by efficient packing of multiple input rectangles/images.

QgsTextureAtlasGenerator can be used to pack either images or raw rectangles. The static createFromRects() or createFromImages() methods should be called with the source images or rectangles, which will return a QgsTextureAtlas containing the results.

createFromImages()

QgsTextureAtlas QgsTextureAtlasGenerator::createFromImages ( const QVector< QImage > & images, int maxSide = 1000 )

static

Creates a texture atlas for a set of images.

The maxSide argument specifies the maximum permitted side size for the atlas. The calculated solution can only be less than or equal to this size - if it cannot fit, then algorithm will gracefully fail and return an invalid QgsTextureAtlas.

createFromRects()

QgsTextureAtlas QgsTextureAtlasGenerator::createFromRects ( const QVector< QRect > & rectangles, int maxSide = 1000 )

static

Creates a texture atlas for a set of rectangles.

This method should be used when the generator is used to pack rectangle shapes only. No image will be associated with the rectangle.

The maxSide argument specifies the maximum permitted side size for the atlas. The calculated solution can only be less than or equal to this size - if it cannot fit, then algorithm will gracefully fail and return an invalid QgsTextureAtlas.
