Types ¶
type BinaryColor ¶
type BinaryColor struct {
Black bool
}
A BinaryColor represents either black or white.
func (BinaryColor) RGBA ¶
func (c BinaryColor) RGBA() (r, g, b, a uint32)
type Bitmap ¶
type Bitmap struct {
// Pix holds the image's pixels. The pixel at (x, y) is Pix[y*Stride + x/8] >> (7 - x&7) & 1.
Pix []uint8
Stride int
// Rect is the image's bounds.
Rect i.Rectangle
}
A Bitmap is an in-memory image of BinaryColor values.
func (*Bitmap) ColorModel ¶
func (*Bitmap) Opaque ¶
Opaque scans the entire image and returns whether or not it is fully opaque.
func (*Bitmap) SetBinary ¶
func (p *Bitmap) SetBinary(x, y int, c BinaryColor)
