Module glitter::image_data [−] [src]

Contains types related to 2D image data.

Structs

ImageFormat	A type that contains the texel type and format that make up a 2D image.
Pixel	A single OpenGL color value, with `u8` components laid out as a C struct in RGBA order. This type is the simplest implementation of `Image2d`, which allows it to be uploaded to a texture.
Pixels	A (heap-allocated) 2D image composed of a list of pixels.

RenderbufferFormat	The various image formats of a renderbuffer.
TexelFormat	The different texel formats.
TexelType	The data types for a texel.

ALPHA	A texel contains only an alpha component.
DEPTH_COMPONENT16	The renderbuffer stores a 16-bit depth component.
RGB	A texel contains red, green, and blue components.
RGB565	The red, green, and blue channels are stored with 5 bits, 6 bits, and 5 bits, respectively.
RGB5_A1	The red, green, and blue channels are stored with 5 bits, and the alpha channel is stored with 1 bit.
RGBA	A texel contains red, green, blue, and alpha components.
RGBA4	The red, green, blue, and alpha channels are all stored with 4 bits.
STENCIL_INDEX8	The renderbuffer stores an 8-bit stencil component.
UNSIGNED_BYTE_TEXEL	Each texel is 4 * 8 bits.
UNSIGNED_SHORT_4_4_4_4	Each texel is 16 bits, with 4, 4-bit components.
UNSIGNED_SHORT_5_5_5_1	Each texel is 16 bits, with 5-bit/5-bit/5-bit/1-bit components.
UNSIGNED_SHORT_5_6_5	Each texel is 16 bits, with 5-bit/6-bit/5-bit components.

A trait for types that that contain 2D image data, which can be uploaded to a texture using a Texture2dBuilder or using the gl.image_2d method.
