Enum glitter::image_data::RenderbufferFormat

pub enum RenderbufferFormat {
    RGBA4,
    RGB565,
    RGB5A1,
    DepthComponent16,
    StencilIndex8,
}

The various image formats of a renderbuffer.

Variants

RGBA4

The red, green, blue, and alpha channels are all stored with 4 bits.

RGB565

The red, green, and blue channels are stored with 5 bits, 6 bits, and 5 bits, respectively.

RGB5A1

The red, green, and blue channels are stored with 5 bits, and the alpha channel is stored with 1 bit.

DepthComponent16

The renderbuffer stores a 16-bit depth component.

StencilIndex8

The renderbuffer stores an 8-bit stencil component.

Methods

impl RenderbufferFormat

pub fn from_gl(gl_enum: GLenum) -> Result<Self, ()>

Convert from a raw OpenGL integer value to an enum variant. Returns an error if the value is not a valid enum variant.

pub fn gl_enum(&self) -> GLenum

Return the OpenGL integer value for a given enum variant.
