[−][src]Struct azul_webrender_api::ImageDescriptor
Metadata (but not storage) describing an image In WebRender.
Fields
format: ImageFormat
Format of the image data.
size: DeviceIntSize
Width and length of the image data, in pixels.
stride: Option<i32>
The number of bytes from the start of one row to the next. If non-None,
compute_stride
will return this value, otherwise it returns
width * bpp
. Different source of images have different alignment
constraints for rows, so the stride isn't always equal to width * bpp.
offset: i32
Offset in bytes of the first pixel of this image in its backing buffer. This is used for tiling, wherein WebRender extracts chunks of input images in order to cache, manipulate, and render them individually. This offset tells the texture upload machinery where to find the bytes to upload for this tile. Non-tiled images generally set this to zero.
flags: ImageDescriptorFlags
Various bool flags related to this descriptor.
Implementations
impl ImageDescriptor
[src]
pub fn new(
width: i32,
height: i32,
format: ImageFormat,
flags: ImageDescriptorFlags
) -> Self
[src]
width: i32,
height: i32,
format: ImageFormat,
flags: ImageDescriptorFlags
) -> Self
Mints a new ImageDescriptor.
pub fn compute_stride(&self) -> i32
[src]
Returns the stride, either via an explicit stride stashed on the object or by the default computation.
pub fn compute_total_size(&self) -> i32
[src]
Computes the total size of the image, in bytes.
pub fn full_rect(&self) -> DeviceIntRect
[src]
Computes the bounding rectangle for the image, rooted at (0, 0).
pub fn is_opaque(&self) -> bool
[src]
Returns true if this descriptor is opaque
pub fn allow_mipmaps(&self) -> bool
[src]
Returns true if this descriptor allows mipmaps
