Trait blit::ToBlitBuffer

pub trait ToBlitBuffer {
    // Required methods
    fn to_blit_buffer_with_alpha(&self, alpha_treshold: u8) -> BlitBuffer;
    fn to_blit_buffer_with_mask_color(&self, mask_color: u32) -> BlitBuffer;
}

Convert external image types to a specialized buffer optimized for blitting.

Can be used to create a custom implementation if you want different image or other formats.

Required Methods

fn to_blit_buffer_with_alpha(&self, alpha_treshold: u8) -> BlitBuffer

Convert the image to a custom BlitBuffer type which is optimized for applying the blitting operations.

It’s assumed that the alpha channel in the resulting pixel is properly set. The alpha treshold is the offset point at which an alpha value will be used as either a transparent pixel or a colored one.

fn to_blit_buffer_with_mask_color(&self, mask_color: u32) -> BlitBuffer

Convert the image to a custom BlitBuffer type which is optimized for applying the blitting operations.

Ignore the alpha channel if set and use only a single color for transparency.
