Enum ContentScale 

pub enum ContentScale {
    Fit,
    Crop,
    FillBounds,
    FillWidth,
    FillHeight,
    Inside,
    None,
}

How an image is scaled to fit the bounds it is drawn into. Compose’s ContentScale.

Variants

Fit

Scales both axes by one factor so the whole image fits inside the bounds, leaving space on one axis.

Crop

Scales both axes by one factor so the image covers the bounds, cropping what overflows.

FillBounds

Scales each axis separately so the image fills the bounds, which distorts its aspect ratio.

FillWidth

Scales both axes by one factor so the image width matches the bounds width.

FillHeight

Scales both axes by one factor so the image height matches the bounds height.

Inside

Like Fit, but never enlarges an image that already fits inside the bounds.

None

Draws the image at its own size without scaling.

Implementations

impl ContentScale

pub fn scaled_size(self, src_size: Size, dst_size: Size) -> Size

Returns the size of an image of src_size after this scale fits it to dst_size. For Crop the result can exceed dst_size. Returns zero size if a side of either size is zero or negative.
