enum InterlaceMode

struct Image ImageInfo

Types 3

structImageInfo

Information about an HDF5 image.

Fields

hsize_t widthWidth of the image in pixels

hsize_t heightHeight of the image in pixels

hsize_t planesNumber of color planes (1 for grayscale, 3 for RGB)

string interlaceInterlace mode string

hssize_t numPalettesNumber of palettes associated with the image

enumInterlaceMode : string

Interlace mode for 24-bit images.

pixel = "INTERLACE_PIXEL"Pixel interlacing (RGBRGBRGB...)

plane = "INTERLACE_PLANE"Plane interlacing (RRR...GGG...BBB...)

structImage

High-level wrapper for HDF5 image operations.

This struct provides convenient methods for creating and manipulating HDF5 images using the High-Level API.

Example:

// Create an 8-bit grayscale image
ubyte[] pixels = new ubyte[width * height];
Image.make8bit(file.handle(), "grayscale", width, height, pixels);

// Create a 24-bit color image
ubyte[] rgb = new ubyte[width * height * 3];
Image.make24bit(file.handle(), "color", width, height, InterlaceMode.pixel, rgb);

Methods

void make8bit(hid_t locId,  string imageName,  hsize_t width,  hsize_t height,
          const  ubyte[]  data)

staticCreates an 8-bit grayscale image.

void make24bit(hid_t locId,  string imageName,  hsize_t width,  hsize_t height,
          InterlaceMode interlace,  const  ubyte[]  data)

staticCreates a 24-bit color image.

void read(hid_t locId, string imageName, ubyte[] data) staticReads image data.

ImageInfo getInfo(hid_t locId, string imageName) staticGets information about an image.

bool isImage(hid_t locId, string imageName) staticChecks if a dataset is an HDF5 image.

void makePalette(hid_t locId,  string paletteName,  const  hsize_t[]  paletteDims,
          const  ubyte[]  data)

staticCreates a palette.

void linkPalette(hid_t locId, string imageName, string paletteName) staticLinks a palette to an image.

void unlinkPalette(hid_t locId, string imageName, string paletteName) staticUnlinks a palette from an image.

hssize_t getNumPalettes(hid_t locId, string imageName) staticGets the number of palettes associated with an image.

void getPaletteInfo(hid_t locId,  string imageName,  int  paletteIndex,
          hsize_t[]  paletteDims)

staticGets palette information.

void getPalette(hid_t locId, string imageName, int paletteIndex, ubyte[] data) staticReads a palette.

bool isPalette(hid_t locId, string paletteName) staticChecks if a dataset is an HDF5 palette.
