jjPIXELMAP class
A rectangular buffer of palette-indexed pixels.
Reference-counted, editable image of 8-bit palette indices that scripts read and write per pixel. It can be built from a tile, an animation frame, a texture, a region of a tile layer, an image file or a blank size, and saved back into a tile, an animation frame or an image file. The bridge for procedural graphics editing.
Public static functions
- static auto CreateFromTile() -> jjPIXELMAP*
- Returns a new instance built from a single tile.
-
static auto CreateFromSize(std::
uint32_t width, std:: uint32_t height) -> jjPIXELMAP* - Returns a new instance of the given size.
- static auto CreateFromFrame(const jjANIMFRAME* animFrame) -> jjPIXELMAP*
- Returns a new instance built from an animation frame.
-
static auto CreateFromLayer(std::
uint32_t left, std:: uint32_t top, std:: uint32_t width, std:: uint32_t height, std:: uint32_t layer) -> jjPIXELMAP* - Returns a new instance built from a region of a tile layer.
-
static auto CreateFromLayerObject(std::
uint32_t left, std:: uint32_t top, std:: uint32_t width, std:: uint32_t height, const jjLAYER* layer) -> jjPIXELMAP* - Returns a new instance built from a region of the given layer.
-
static auto CreateFromTexture(std::
uint32_t animFrame) -> jjPIXELMAP* - Returns a new instance built from a texture.
-
static auto CreateFromFilename(const String& filename,
const jjPAL* palette,
std::
uint8_t threshold) -> jjPIXELMAP* - Returns a new instance built from an image file, mapped onto the given palette.
