Abstract interface for a tile.
A tile is a rectangular array of pixels of a certain pixel type.
|
pure virtual |
Returns a pointer to the raw tile data according to the pixel type of the tile.
This methods is used for fast, direct read access to the raw tile data. It is expected that the data is stored in row-major layout without any padding. In case of mi::Color, the components are expected to be stored in RGBA order.
The total size of the buffer in bytes is
where x is the result of get_resolution_x(), y is the result of get_resolution_y(), and bpp is the number of bytes per pixel.

pure virtual |
Returns a pointer to the raw tile data according to the pixel type of the tile.
This methods is used for fast, direct write access to the raw tile data. It is expected that the data is stored in row-major layout without any padding. In case of mi::Color, the components are expected to be stored in RGBA order.
The total size of the buffer in bytes is
where x is the result of get_resolution_x(), y is the result of get_resolution_y(), and bpp is the number of bytes per pixel.
|
pure virtual |
Looks up a certain pixel at the given coordinates.
The offsets are relative to the lower left border of the tile. The floats argument must point to at least 4 floats, e.g., you pass the address of mi::math::Color.r.
This method is a rather slow, but convenient access method. Typically, the get_data() method is faster and can handle arbitrary data types without pixel type conversion.
