attribute

Modules

block_type_strings The string literals used to represent a BlockType in a file.
type_names Contains string literals identifying the type of an attribute.

ChannelDescription A single channel in an layer. Does not contain the actual pixel data, but instead merely describes it.
ChannelList A List of channels. Channels must be sorted alphabetically.
Chromaticities The color space of the pixels.
FloatRect A rectangular section anywhere in 2D float space.
IntegerBounds A rectangular section anywhere in 2D integer space. Valid from minimum coordinate (including) -1,073,741,822 to maximum coordinate (including) 1,073,741,822, the value of (i32::MAX/2 -1).
KeyCode Uniquely identifies a motion picture film frame.
Preview A small rgba image of i8 values that approximates the real exr image.
Text A byte array with each byte being a char. This is not UTF and it must be constructed from a standard string.
TileDescription Describes how the layer is divided into tiles. Specifies the size of each tile in the image and whether this image contains multiple resolution levels.
TimeCode Contains time information for this frame within a sequence. Also defined methods to compile this information into a TV60, TV50 or Film24 bit sequence, packed into u32.

AttributeValue Contains one of all possible attributes. Includes a variant for custom attributes.
BlockType layer type, specifies block type and deepness.
Compression Specifies which compression method to use.
EnvironmentMap If this attribute is present, it describes how this texture should be projected onto an environment.
LevelMode Whether to also store increasingly smaller versions of the original image.
LineOrder In what order the Blocks of pixel data appear in a file.
SampleType The type of samples in this channel.

byte_size Number of bytes this attribute would consume in an exr file.
read Read the attribute without validating. The result may be Ok even if this single attribute is invalid.
validate Validate this attribute.
write Without validation, write this attribute to the byte stream.

DataWindow The integer rectangle describing where an layer is placed on the infinite 2D global space.
DisplayWindow The integer rectangle limiting which part of the infinite 2D global space should be displayed.
Matrix3x3 A float matrix with three rows and three columns.
Matrix4x4 A float matrix with four rows and four columns.
Rational An integer dividend and divisor, together forming a ratio.
TextBytes The raw bytes that make up a string in an exr file. Each u8 is a single char.
TextSlice A byte slice, interpreted as text
