Class: QgsTextureAtlas

Encapsulates a texture atlas.

QgsTextureAtlas contains the packed regions for aggregated texture atlases, and optionally the packed texture map.

See QgsTextureAtlasGenerator for a class which automatically creates texture atlases.

Added in version 4.0.

class qgis._3d.QgsTextureAtlas[source]

Bases: object

atlasSize(self) → QSize[source]

Returns the total size required for the atlas, i.e. the total size for the packed images and rectangles.

Return type:

QSize

count(self) → int[source]

Returns the number of textures in the atlas.

Return type:

int

isValid(self) → bool[source]

Returns True if the atlas is valid.

Return type:

bool

rect(self, index: int) → QRect[source]

Returns the packed rectangle for the texture with the specified index.

Raises:

IndexError – if no texture with the specified index exists.

Parameters:

index (int)

Return type:

QRect

renderAtlasTexture(self) → QImage[source]

Renders the combined texture atlas, containing all source images.

Note

This may be a null image if the atlas was created with rectangles alone.

Return type:

QImage

renderDebugTexture(self) → QImage[source]

Renders a debug texture.

The debug texture renders all packed rectangles with a unique color, and can be used to visualize the solution.

Return type:

QImage
