Struct zng_view_api::image::ImageRequest

pub struct ImageRequest<D> {
    pub format: ImageDataFormat,
    pub data: D,
    pub max_decoded_len: u64,
    pub downscale: Option<ImageDownscale>,
    pub mask: Option<ImageMaskMode>,
}

Represent a image load/decode request.

Fields

format: ImageDataFormat

Image data format.

data: D

Image data.

Bytes layout depends on the format, data structure is IpcBytes or IpcBytesReceiver in the view API.

max_decoded_len: u64

Maximum allowed decoded size.

View-process will avoid decoding and return an error if the image decoded to BGRA (4 bytes) exceeds this size. This limit applies to the image before the resize_to_fit.

downscale: Option<ImageDownscale>

A size constraints to apply after the image is decoded. The image is resized so both dimensions fit inside the constraints, the image aspect ratio is preserved.

mask: Option<ImageMaskMode>

Convert or decode the image into a single channel mask (R8).
