Member Enumeration Documentation

Type

enum Type : uint8_t

Type of supported images.

Enumerator
BMP	Windows bitmaps - bmp, dib. Raster graphics image file format developed by Microsoft. [18]
PNG	Portable Network Graphics - png. PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. [14]
WSQ	Wavelet Scalar Quantization - wsq. WSQ (Wavelet Scalar Quantization), also known as FBI Print Format, is a raster image file format used for storing images of prints. It uses lossy wavelet compression, and supports only grayscale images.
IRAW	Innovatrics proprietary RAW image - iraw. The format is IRAW (4 bytes), width (4 bytes, big endian unsigned int), height (4 bytes, big endian unsigned int), dpi (4 bytes, big endian unsigned int), type (4 bytes, big endian unsigned int), data.
JPG	Joint Photographic Experts Group - jpeg, jpg, jpe. JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. [12]
TIFF	Tagged Image File Format - tiff, tif. TIF is an image file format for storing raster graphics images, popular among graphic artists, the publishing industry, and photographers. [15]
JPG2000	JPEG 2000 is an image compression standard and coding system - jp2. JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee with the intention of superseding their original JPEG standard (created in 1992) [13]
WEBP	WebP is an image file format developed by Google - webp. It is intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression as well as animation and alpha transparency. [16]
