Struct ImageLoader 

pub struct ImageLoader {
    pub device: Device,
    /* private fields */
}

Helper for decoding CPU bitmap data into vk-graph images.

Fields

device: Device

The device used to create temporary buffers, images, and decode pipelines.

Implementations

impl ImageLoader

pub fn new(device: &Device) -> Result<Self, DriverError>

Creates a new image loader and its internal decode pipelines.

pub fn decode_bitmap( &mut self, queue_family_index: u32, queue_index: u32, pixels: &[u8], format: ImageFormat, width: u32, height: u32, is_srgb: bool, ) -> Result<Arc<Image>>

Decodes bitmap pixels into an image and uploads it through a temporary graph submission.

pub fn decode_linear( &mut self, queue_family_index: u32, queue_index: u32, pixels: &[u8], format: ImageFormat, width: u32, height: u32, ) -> Result<Arc<Image>>

Decodes a linear-color bitmap into an image.

pub fn decode_srgb( &mut self, queue_family_index: u32, queue_index: u32, pixels: &[u8], format: ImageFormat, width: u32, height: u32, ) -> Result<Arc<Image>>

Decodes an sRGB bitmap into an image.

pub fn load_bitmap_font<'a>( &mut self, queue_family_index: u32, queue_index: u32, font: BMFont, pages: impl IntoIterator<Item = (&'a [u8], u32, u32)>, ) -> Result<BitmapFont>

Loads a bitmap font by decoding each supplied page image and pairing it with the font data.

Trait Implementations

impl Debug for ImageLoader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
