Enum ScalingMode 

pub enum ScalingMode {
    FillCenter,
    FillStart,
    FillEnd,
    FitCenter,
    FitStart,
    FitEnd,
}

Represents various modes for proportional scaling of a texture.

Can be used in SpriteImageMode::Scale.

Variants

FillCenter

Scale the texture uniformly (maintain the texture’s aspect ratio) so that both dimensions (width and height) of the texture will be equal to or larger than the corresponding dimension of the target rectangle. Fill sprite with a centered texture.

FillStart

Scales the texture to fill the target rectangle while maintaining its aspect ratio. One dimension of the texture will match the rectangle’s size, while the other dimension may exceed it. The exceeding portion is aligned to the start:

• Horizontal overflow is left-aligned if the width exceeds the rectangle.
• Vertical overflow is top-aligned if the height exceeds the rectangle.

FillEnd

Scales the texture to fill the target rectangle while maintaining its aspect ratio. One dimension of the texture will match the rectangle’s size, while the other dimension may exceed it. The exceeding portion is aligned to the end:

• Horizontal overflow is right-aligned if the width exceeds the rectangle.
• Vertical overflow is bottom-aligned if the height exceeds the rectangle.

FitCenter

Scaling the texture will maintain the original aspect ratio and ensure that the original texture fits entirely inside the rect. At least one axis (x or y) will fit exactly. The result is centered inside the rect.

FitStart

Scaling the texture will maintain the original aspect ratio and ensure that the original texture fits entirely inside rect. At least one axis (x or y) will fit exactly. Aligns the result to the left and top edges of rect.

FitEnd

Scaling the texture will maintain the original aspect ratio and ensure that the original texture fits entirely inside rect. At least one axis (x or y) will fit exactly. Aligns the result to the right and bottom edges of rect.
