HdrSlice class

A slice is the data for an image framebuffer for a single channel.

Constructors

HdrSlice(String? name, int width, int height, int type, int bitsPerSample)
HdrSlice.from(HdrSlice other)
Create a copy of the other HdrSlice.

Properties

bitsPerSample → int
How many bits per sample, either 8, 16, 32, or 64.
final
data → List
data will be one of the type data lists, depending on the type and bitsPerSample. 16-bit FLOAT slices will be stored in a Uint16List.
final
hashCode → int
The hash code for this object.
no setterinherited
height → int
final
isFloat → bool
Does this channel store floating-point data?
no setter
name → String?
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
type → int
Indicates the type of data stored by the slice, either HdrImage.INT, HdrImage.FLOAT, or HdrImage.UINT.
final
width → int

Methods

getBytes() → Uint8List
Get the raw bytes of the data buffer.
getFloat(int x, int y) → double
Get the float value of the sample at the coordinates x,y. Half samples are converted to double.
getInt(int x, int y) → int
Get the int value of the sample at the coordinates x,y. An exception will occur if the slice stores FLOAT data.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setFloat(int x, int y, num v) → void
Set the float value of the sample at the coordinates x,y for FLOAT slices.
setInt(int x, int y, int v) → void
Set the int value of the sample at the coordinates x,y for INT and UINT slices.
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
