Struct glin::texture::DataFormat

pub struct DataFormat {
    pub width: u32,
    pub height: u32,
    pub depth: u32,
    pub format: GLenum,
    pub ty: GLenum,
    pub level: u32,
    pub xoffset: i32,
    pub yoffset: i32,
    pub zoffset: i32,
}

Used to upload data to a Texture

DataFormat implements Default so when uploading data to a texture where the data and the texture ahve the same size, format and type and the data is going to be uploaded to level 0 a Default DataFormat can be used by calling Default::default() or DataFormat::default()

If some fields are not the same the rest can be defaulted by using ..Default::default() as in

use glin::texture::DataFormat;
texture.load_data(&data, DataFormat{
   width: 20,
   height: 20,
   xoffset: 20,
   yoffset: 20,
   level: 1,
   ..Default::default()
});

Fields

width: u32

height: u32

depth: u32

format: GLenum

ty: GLenum

level: u32

xoffset: i32

yoffset: i32

zoffset: i32
