ElementViewImage alias ElementViewImage(R) = ViewImage!(ElementType!R): Resolves to an Image with the same color type as the element type of the view range R.
GetInputColor alias GetInputColor(COLOR, INPUT) = Select!(is(COLOR == InputColor), INPUT, COLOR): Resolves COLOR to INPUT if it is InputColor.
ViewImage alias ViewImage(V) = Image!(ViewColor!V): Resolves to an Image with the same color type as the view V.

Enums

PNGColourType enum PNGColourType: PNG image attributes.
PNGCompressionMethod enum PNGCompressionMethod: Undocumented in source.
PNGFilterAdaptive enum PNGFilterAdaptive: Undocumented in source.
PNGFilterMethod enum PNGFilterMethod: Undocumented in source.
PNGInterlaceMethod enum PNGInterlaceMethod: Undocumented in source.
bitmapNeedV4HeaderForRead eponymoustemplate bitmapNeedV4HeaderForRead(COLOR): Undocumented in source.
bitmapNeedV4HeaderForWrite eponymoustemplate bitmapNeedV4HeaderForWrite(COLOR): Whether to use a V4 BMP header for the given color type. Different software have different standards regarding alpha without a V4 header. ImageMagick will write BMPs with alpha without a V4 header, but not all software will read them.
isTargetColor eponymoustemplate isTargetColor(C, TARGET): Workaround for https://issues.dlang.org/show_bug.cgi?id=12433

Functions

bitmapChannelMasks uint[4] bitmapChannelMasks(): Calculates bV4RedMask etc. values for the given color type.
copy auto copy(SRC src, TARGET target): Copy the given view into the specified target.
copy auto copy(SRC src): Copy the given view into a newly-allocated image.
copyPixels void copyPixels(SRC src, StorageType[] dst): Copy a view's pixels (top-to-bottom) to a StorageType buffer. Rows are assumed to be StorageType.sizeof-aligned.
copyScanline void copyScanline(SRC src, xy_t y, StorageType[] dst): Copy the indicated row of src to a StorageType buffer.
downscaleTo auto downscaleTo(SRC src, TARGET target): Downscaling copy (averages colors in source per one pixel in target).
downscaleTo auto downscaleTo(SRC src, xy_t w, xy_t h): Downscales an image to a certain size.
fromPixels auto fromPixels(INPUT[] input, uint w, uint h, TARGET target)
auto fromPixels(INPUT[] input, uint w, uint h): Loads a raw COLOR[] into an image of the indicated size.
hjoin auto hjoin(R images, TARGET target)
auto hjoin(R images): Splice multiple images horizontally.
makePNG ubyte[] makePNG(PNGChunk[] chunks): Construct a PNG file out of the given PNG chunks.
parseBMP auto parseBMP(const(void)[] data, TARGET target)
auto parseBMP(const(void)[] data): Parses a Windows bitmap (.bmp) file.
parsePBM auto parsePBM(const(void)[] vdata, TARGET target)
auto parsePBM(const(void)[] vdata): Parses a binary Netpbm monochrome (.pgm) or RGB (.ppm) file.
toBMP ubyte[] toBMP(SRC src): Creates a Windows bitmap (.bmp) file.
toPBM ubyte[] toPBM(SRC src): Creates a binary Netpbm monochrome (.pgm) or RGB (.ppm) file.
toPNG ubyte[] toPNG(SRC src, int compressionLevel): Creates a PNG file. Only basic PNG features are supported (no filters, interlacing, palettes etc.)
toRef ImageRef!(ViewColor!SRC) toRef(SRC src): Convert a direct view to an ImageRef. Assumes that the rows are evenly spaced.
viewBMP auto viewBMP(V data): Returns a view representing a BMP file. Does not copy pixel data.
vjoin auto vjoin(R images, TARGET target)
auto vjoin(R images): Splice multiple images vertically.

Properties

bitmapPixelStride size_t bitmapPixelStride [@property getter]: Calculates the BMP pixel stride for the given StorageType and width.

Static variables

pngSignature ubyte[8] pngSignature;: The PNG file signature.

Structs

Image struct Image(COLOR, StorageType = PlainStorageUnit!COLOR): An in-memory image. Pixels are stored as contiguous scanlines, with each scanline consisting of one or more StorageType.
ImageRef struct ImageRef(COLOR, StorageType = PlainStorageUnit!COLOR): Represents a reference to COLOR data already existing elsewhere in memory. Assumes that pixels are stored row-by-row, with a known distance between each row.
InputColor struct InputColor: Placeholder type used where an output color is specified, which indicates that the output color type should be the same as the input color.
PNGChunk struct PNGChunk: A PNG chunk.
PNGChunkFooter struct PNGChunkFooter: Undocumented in source.
PNGChunkHeader struct PNGChunkHeader: Undocumented in source.
PNGHeader struct PNGHeader: PNG header (IHDR).
TargetColor struct TargetColor: Workaround for https://issues.dlang.org/show_bug.cgi?id=12433

Templates

BMPStorageType template BMPStorageType(COLOR): Resolves to the storage type to use for the given COLOR.
downscale template downscale(int HRX, int HRY = HRX): Performs linear downscale by a constant factor
