Overview ¶

package render provides several routines for drawing simple shapes and gradients. It also makes an attempt at unifying colors with the Color type.

Types ¶

type Color ¶

type Color struct {
	// contains filtered or unexported fields
}

func NewColor ¶

func NewColor(clr int) Color

func NewGradient ¶

func NewGradient(start, end int) Color

func NewImageColor ¶

func NewImageColor(clr color.Color) Color

func NewImageGradient ¶

func NewImageGradient(startClr, endClr color.Color) Color

func (*Color) ColorSet ¶

func (c *Color) ColorSet(clr int)

func (*Color) GradientSet ¶

func (c *Color) GradientSet(start, end int)

func (Color) ImageColor ¶

func (c Color) ImageColor() color.RGBA

func (Color) Int ¶

func (c Color) Int() int

func (Color) IsGradient ¶

func (c Color) IsGradient() bool

IsGradient returns whether the theme color is a gradient or not. Basically, a themeColor can either be a regular color (like an int) or a gradient when both 'start' and 'end' have valid color values.

func (Color) RGB ¶

func (c Color) RGB() (r, g, b int)

func (Color) RGB8 ¶

func (c Color) RGB8() (r, g, b uint8)

func (Color) Steps ¶

func (c Color) Steps(size int) []color.RGBA

steps returns a slice of colors corresponding to the gradient of colors from start to end. The size is determined by the 'size' parameter. The first and last colors in the slice are guaranteed to be c.start and c.end. (Unless the size is 1, in which case, the first and only color in the slice is c.start.) XXX: Optimize.

func (Color) String ¶

func (c Color) String() string

func (Color) Uint32 ¶

func (c Color) Uint32() uint32

type Image ¶

type Image struct {
	*xgraphics.Image
}

func New ¶

func New(ximg *xgraphics.Image) *Image

func NewBorder ¶

func NewBorder(X *xgbutil.XUtil, borderType int, borderColor,
	bgColor Color, width, height, gradientType, gradientDir int) *Image

func NewCorner ¶

func NewCorner(X *xgbutil.XUtil, borderType int, borderColor,
	bgColor Color, width, height, diagonal int) *Image

func NewSolid ¶

func NewSolid(X *xgbutil.XUtil, bgColor Color, width, height int) *Image

func (*Image) Gradient ¶

func (img *Image) Gradient(gradientType, gradientDir int, clr Color)

func (*Image) GradientFunc ¶

func (img *Image) GradientFunc(gradientType, gradientDir int, clr Color,
	pixel func(x, y int) bool)

XXX: Optimize.

func (*Image) ThinBorder ¶

func (img *Image) ThinBorder(borderType int, borderColor Color)

XXX: Optimize.
