类
class	Image
	This module is responsible for decoding files such as PNG, GIF, JPEG into raw pixel data, as well as parsing compressed formats which are designed to be uploaded to the GPU and rendered without being un-compressed. This module does not know how to draw images on screen; only love.graphics knows that. 更多...

class	ImageData
	Represents raw pixel data. 更多...

union	Row

struct	UvPaintReceipt
	Owning receipt for one UV-space raster paint operation. 更多...

struct	UvPaintRegion
	Reusable renderer-neutral bounds for one normalized UV paint operation. 更多...

class	UvPaintSession
	Transactional, renderer-independent UV texture painting session. 更多...

class	WebPHandler
	Internal decoder adapter; each call owns its output and borrows input synchronously. 更多...

Result< UvPaintRegion > eve::image::prepareUvPaintRegionResult	(	int	targetWidth,
		int	targetHeight,
		float	u,
		float	v,
		float	radiusU,
		float	radiusV,

	)

Validate and prepare the canonical clipped region for a UV brush.

参数

targetWidth	Positive target width in pixels.
targetHeight	Positive target height in pixels.
u	Normalized horizontal center; values outside [0,1] are clamped.
v	Normalized vertical center; values outside [0,1] are clamped.
radiusU	Non-negative normalized horizontal radius.
radiusV	Non-negative normalized vertical radius.
r	Red channel in [0,1].
g	Green channel in [0,1].
b	Blue channel in [0,1].
a	Alpha/coverage channel in [0,1].
flipV	Convert bottom-left UV V to top-left image coordinates when true.

返回: Owning region, or a structured diagnostic without side effects. @ownership Returned value owns all its state and retains no backend objects. @thread Pure and thread-safe. @reentrancy Does not invoke callbacks.
