Member Function Documentation

◆ free_data()

void blender::bke::image::partial_update::ImageTileData::free_data ( )

inlineoverridevirtual

Unload the data that has been loaded.

Invoked when changes are on a different tile compared to the previous tile or when finished iterating over the changes.

Implements blender::bke::image::partial_update::AbstractTileData.

◆ init_data()

void blender::bke::image::partial_update::ImageTileData::init_data ( TileNumber tile_number )

inlineoverridevirtual

Load the data for the given tile_number.

Invoked when changes are on a different tile compared to the previous tile..

Member Data Documentation

◆ image

Image* blender::bke::image::partial_update::ImageTileData::image

Not owned Image that is being iterated over.

Definition at line 140 of file BKE_image_partial_update.hh.

◆ image_user

ImageUser blender::bke::image::partial_update::ImageTileData::image_user = {0}

Local copy of the image user.

The local copy is required so we don't change the image user of the caller. We need to change it in order to request data for a specific tile.

◆ tile

ImageTile* blender::bke::image::partial_update::ImageTileData::tile = nullptr

ImageTile associated with the loaded tile. Data is not owned by this instance but by the image.

◆ tile_buffer

ImBuf* blender::bke::image::partial_update::ImageTileData::tile_buffer = nullptr

ImBuf of the loaded tile.

Can be nullptr when the file doesn't exist or when the tile hasn't been initialized.
