Struct RgbData 

pub struct RgbData {
    pub data: Vec<u8>,
    pub width: u32,
    pub height: u32,
    pub interpolate: bool,
    pub scale_factors: (f32, f32),
}

A structure holding 3-channel RGB data.

Fields

data: Vec<u8>

The actual data. It is guaranteed to have the length width * height * 3.

width: u32

The width.

height: u32

The height.

interpolate: bool

Whether the image should be interpolated.

scale_factors: (f32, f32)

Additional scaling factors to apply to the image.

In most cases, those factors will just be 1.0, and you can ignore them. There are two situations in which they will not be equal to 1:

1. The PDF provided wrong metadata about the width/height of the image, which needs to be corrected
2. A lower resolution of the image was requested, in which case it needs to be scaled up so that it still covers the same area.

The first number indicates the x scaling factor, the second number the y scaling factor.

Trait Implementations

impl Clone for RgbData

fn clone(&self) -> RgbData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
