Functions ¶
func Generate ¶
Generate reads an input sprite texture and generates a reference sprite file, and optionally a palette texture. If outPaletteTexture is supplied then the R channel will be rescaled based on the palette texture size; otherwise it will be the colour index (and limited to 256 colours)
func GenerateFromImage ¶
func GenerateFromImage(img image.Image, outImagePath, outPaletteTexture string) ([]color.RGBA, error)
GenerateFromImage reads an image and generates a reference sprite file, and optionally a palette texture. If outPaletteTexture is supplied then the R channel will be rescaled based on the palette texture size; otherwise it will be the colour index (and limited to 256 colours)
Types ¶
type TexCoordRescale ¶
type TexCoordRescale struct {
// contains filtered or unexported fields
}
Texture coordinate rescaler with saved factors
func NewTexCoordRescale ¶
func NewTexCoordRescale(paletteWidth, paletteHeight int) TexCoordRescale
