IndexedImage

An image that consists of indexes into a color palette. Use getAsTrueColorImage if you don't care about palettes

@safe

class IndexedImage : MemoryImage {

bool hasAlpha;

Color[] palette;

ubyte[] data;

int height();

IndexedImage clone();

this(int w, int h);

TrueColorImage getAsTrueColorImage();

TrueColorImage convertToTrueColor();

ubyte getOrAddColor(Color c);

int numColors();

ubyte addColor(Color c);

}

Constructors

this this(int w, int h): .

Functions

addColor ubyte addColor(Color c): Adds an entry to the palette, returning its index
clone IndexedImage clone(): .
convertToTrueColor TrueColorImage convertToTrueColor(): Creates a new TrueColorImage based on this data
getAsTrueColorImage TrueColorImage getAsTrueColorImage(): returns a new image
getOrAddColor ubyte getOrAddColor(Color c): Gets an exact match, if possible, adds if not. See also: the findNearestColor free function.
height int height(): .
numColors int numColors(): Number of colors currently in the palette (note: palette entries are not necessarily used in the image data)
width int width(): .

Variables

data ubyte[] data;: the data as indexes into the palette. Stored left to right, top to bottom, no padding.
palette Color[] palette;: .

From MemoryImage

getAsTrueColorImage TrueColorImage getAsTrueColorImage(): gets it as a TrueColorImage. May return this or may do a conversion and return a new image
width int width(): Image width, in pixels
height int height(): Image height, in pixels
getPixel Color getPixel(int x, int y): Get image pixel. Slow, but returns valid RGBA color (completely transparent for off-image pixels).
setPixel void setPixel(int x, int y, Color clr): Set image pixel.
clone MemoryImage clone(): Returns a copy of the image
fromImage MemoryImage fromImage(T filename): Load image from file. This will import arsd.image to do the actual work, and cost nothing if you don't use it.
fromImageFile alias fromImageFile = fromImage: Convenient alias for fromImage
