Common types shared between the encoder and decoder
Structs§
- Animation
Control - Animation control information
- Coding
Independent Code Points - Coding-independent code points (cICP) specify the color space (primaries), transfer function, matrix coefficients and scaling factor of the image using the code points specified in ITU-T-H.273.
- Content
Light Level Info - Content light level information of HDR content.
- Frame
Control - Frame control information
- Info
- PNG info struct
- Mastering
Display Color Volume - Mastering Display Color Volume (mDCV) used at the point of content creation, as specified in SMPTE-ST-2086.
- Parameter
Error - Pixel
Dimensions - Pixel dimensions information
- Scaled
Float - An unsigned integer scaled version of a floating point value, equivalent to an integer quotient with fixed denominator (100_000)).
- Source
Chromaticities - Chromaticities of the color space primaries
- Transformations
- Output transformations
Enums§
- BitDepth
- Bit depth of the PNG file. Specifies the number of bits per sample.
- BlendOp
- How pixels are written into the buffer.
- Bytes
PerPixel 🔒 - Internal count of bytes per pixel. This is used for filtering which never uses sub-byte units. This essentially reduces the number of possible byte chunk lengths to a very small set of values appropriate to be defined as an enum.
- Color
Type - Describes how a pixel is encoded.
- Compression
- The type and strength of applied compression.
- Dispose
Op - How to reset buffer of an animated png (APNG) at the end of a frame.
- Parameter
Error 🔒Kind - Srgb
Rendering Intent - The rendering intent for an sRGB image.
- Unit
- Physical unit of the pixel dimensions
