ImageFormat Enum

Namespace: Meziantou.Framework.Imaging
Assembly: Meziantou.Framework.Imaging.dll
Package: Meziantou.Framework.Imaging 1.2.11
Available in package assets: net10.0net11.0

Identifies an encoded image file format.

public enum ImageFormat

Remarks

Formats are detected from content, never from file names. Animated PNG (APNG) is reported as ImageFormat.Png: it is a PNG variant, not a competing signature. New formats are added as new members.

Fields

Name	Value	Description
`Unknown`	`0`	The format is unknown or not recognized.
`Png`	`1`	Portable Network Graphics, including animated PNG (APNG).
`Gif`	`2`	Graphics Interchange Format (GIF87a and GIF89a).
`Jpeg`	`3`	JPEG (JFIF/EXIF) sequential and progressive images, Huffman coded or arithmetic coded.
`WebP`	`4`	WebP (RIFF container): lossy VP8 and lossless VP8L still images and animations.
`Qoi`	`5`	Quite OK Image format: lossless 8-bit RGB and RGBA still images.
`Bmp`	`6`	Windows BMP (device-independent bitmap), uncompressed subset.
`Tga`	`7`	Truevision TGA (TARGA), true-color, grayscale and color-mapped still images.
`Pnm`	`8`	Netpbm portable anymap family: PBM, PGM, PPM (`P1` to `P6`) and PAM (`P7`).
`Tiff`	`9`	Tagged Image File Format, including BigTIFF. A TIFF file is a document of one or more pages; use `ImageCollection` to reach pages other than the first one.
`Ico`	`10`	Windows icon container. An icon file holds alternative representations of one drawing; use `ImageCollection` to reach representations other than the default one.
`Cur`	`11`	Windows cursor container: an icon directory whose entries also carry a hotspot.
`Ani`	`12`	Windows animated cursor (RIFF `ACON` container): an animation whose frames are icon or cursor images, each with its own hotspot (`FrameMetadata.Hotspot`).
`Avif`	`13`	AV1 Image File Format: still images and image sequences coded with AV1 in an ISO base media (HEIF) container.
`JpegXl`	`14`	JPEG XL (ISO/IEC 18181): a bare codestream or its container, still images and animations, lossy (VarDCT) and lossless (Modular) coding. Encoding is lossless.
`Heic`	`15`	High Efficiency Image File Format images coded with HEVC (H.265): still images and image sequences in an ISO base media (HEIF) container.
`Jpeg2000`	`16`	JPEG 2000 (ISO/IEC 15444-1): a codestream or a JP2 file, coded with the reversible or the irreversible wavelet transformation. Codestreams that use the high-throughput block coder (ISO/IEC 15444-15, HTJ2K) are read.
`OpenExr`	`17`	OpenEXR: high dynamic range scene-linear images of 16-bit (half) or 32-bit floating-point samples, stored as scan lines or tiles with lossless or lossy compression.
