Struct printpdf::xobject::ImageXObject

    pub width: Px,
    pub height: Px,
    pub color_space: ColorSpace,
    pub bits_per_component: ColorBits,

Fields

width: Px

Width of the image (original width, not scaled width)

height: Px

Height of the image (original height, not scaled height)

color_space: ColorSpace

Color space (Greyscale, RGB, CMYK)

bits_per_component: ColorBits

Bits per color component (1, 2, 4, 8, 16) - 1 for black/white, 8 Greyscale / RGB, etc. If using a JPXDecode filter (for JPEG images), this can be inferred from the image data

interpolate: bool

Should the image be interpolated when scaled?

image_data: Vec<u8>

The actual data from the image

image_filter: Option<ImageFilter>

Decompression filter for image_data, if None assumes uncompressed raw pixels in the expected color format.

clipping_bbox: Option<CurTransMat>

Required bounds to clip the image, in unit space Default value: Identity matrix ([1 0 0 1 0 0]) - used when value is None
