Trait exr::image::crop::Crop

pub trait Crop: Sized {
    type Cropped;

    // Required method
    fn crop(self, bounds: IntegerBounds) -> Self::Cropped;

    // Provided method
    fn try_crop(
        self,
        bounds: Option<IntegerBounds>,
    ) -> CropResult<Self::Cropped, Self> { ... }
}

Crop some pixels ways when specifying a smaller rectangle

Required Associated Types

type Cropped

The type of this image after cropping (probably the same as before)

Required Methods

fn crop(self, bounds: IntegerBounds) -> Self::Cropped

Crop the image to exclude unwanted pixels. Panics for invalid (larger than previously) bounds. The bounds are specified in absolute coordinates. Does not reduce allocation size of the current image, but instead only adjust a few boundary numbers. Use reallocate_cropped() on the return value to actually reduce the memory footprint.

Provided Methods

fn try_crop( self, bounds: Option<IntegerBounds>, ) -> CropResult<Self::Cropped, Self>

Reduce your image to a smaller part, usually to save memory. Crop if bounds are specified, return the original if no bounds are specified. Does not reduce allocation size of the current image, but instead only adjust a few boundary numbers. Use reallocate_cropped() on the return value to actually reduce the memory footprint.
