Enum icns::PixelFormat
[−]
[src]
pub enum PixelFormat {
RGBA,
RGB,
GrayAlpha,
Gray,
Alpha,
}Formats for storing pixel data in an image.
This type determines how the raw data array of an
Image is to be interpreted.
Regardless of format, pixel data for an image is always stored one complete pixel at a time, in row-major order (that is, the top-left pixel comes first, followed by the rest of the top row from left to right; then comes the second row down, again from left to right, and so on until finally the bottom-right pixel comes last).
Variants
RGBA | 32-bit color with alpha channel. Each pixel is four bytes, with red first and alpha last. | |
RGB | 24-bit color with no alpha. Each pixel is three bytes, with red first and blue last. | |
GrayAlpha | 16-bit grayscale-with-alpha. Each pixel is two bytes, with the grayscale value first and alpha second. | |
Gray | 8-bit grayscale with no alpha. Each pixel is one byte (0=black, 255=white). | |
Alpha | 8-bit alpha mask with no color. Each pixel is one byte (0=transparent, 255=opaque). |
Methods
impl PixelFormat
fn bits_per_pixel(self) -> u32
Returns the number of bits needed to store a single pixel in this format.
