Enum exr::image::crop::CropResult

source · [−]

pub enum CropResult<Cropped, Old> {
    Cropped(Cropped),
    Empty {
        original: Old,
    },
}

Expand description

Cropping an image fails if the image is fully transparent. Use [or_crop_to_1x1_if_empty] or [or_none_if_empty] to obtain a normal image again.

Variants

`Cropped(Cropped)`

The image contained some pixels and has been cropped or left untouched

`Empty`

Fields

original: Old

The fully discarded image which caused the cropping to fail

All pixels in the image would be discarded, removing the whole image

Implementations

source

impl<Cropped, Original> CropResult<Cropped, Original>

source

pub fn or_none_if_empty(self) -> Option<Cropped>

If the image was fully empty, return None, otherwise return Some(cropped_image).

source

pub fn or_crop_to_1x1_if_empty(self) -> Cropped where
Original: Crop<Cropped = Cropped> + GetBounds,

If the image was fully empty, crop to one single pixel of all the transparent pixels instead, leaving the layer intact while reducing memory usage.
