Expand description
Describes how the backend should choose a pixel format.
Fields§
§hardware_accelerated: Option<bool>
If true, only hardware-accelerated formats will be considered. If false, only software
renderers. None
means “don’t care”. Default is Some(true)
.
color_bits: Option<u8>
Minimum number of bits for the color buffer, excluding alpha. None
means “don’t care”.
The default is Some(24)
.
float_color_buffer: bool
If true, the color buffer must be in a floating point format. Default is false
.
Using floating points allows you to write values outside of the [0.0, 1.0]
range.
alpha_bits: Option<u8>
Minimum number of bits for the alpha in the color buffer. None
means “don’t care”.
The default is Some(8)
.
depth_bits: Option<u8>
Minimum number of bits for the depth buffer. None
means “don’t care”.
The default value is Some(24)
.
stencil_bits: Option<u8>
Minimum number of bits for the depth buffer. None
means “don’t care”.
The default value is Some(8)
.
double_buffer: Option<bool>
If true, only double-buffered formats will be considered. If false, only single-buffer
formats. None
means “don’t care”. The default is Some(true)
.
multisampling: Option<u16>
Contains the minimum number of samples per pixel in the color, depth and stencil buffers.
None
means “don’t care”. Default is None
.
A value of Some(0)
indicates that multisampling must not be enabled.
stereoscopy: bool
If true, only stereoscopic formats will be considered. If false, only non-stereoscopic
formats. The default is false
.
srgb: bool
If true, only sRGB-capable formats will be considered. If false, don’t care.
The default is false
.
release_behavior: ReleaseBehavior
The behavior when changing the current context. Default is Flush
.
