Types ¶
type BlendMode ¶
type BlendMode = ebiten.Blend
The blend mode specifies how to compose colors when drawing glyphs:
- Without Ebitengine, the blend mode can be BlendOver, BlendReplace, BlendAdd, BlendSub, BlendMultiply, BlendCut and BlendHue.
- With Ebitengine, the blend mode is ebiten.Blend.
type GlyphMask ¶
type GlyphMask = *ebiten.Image
A GlyphMask is the image that results from rasterizing a glyph. You rarely need to use glyph masks directly unless you are working with advanced functions.
Without Ebitengine, GlyphMask defaults to *image.Alpha. The image bounds are adjusted to allow drawing the glyph at its intended position. In particular, bounds.Min.Y is typically negative, with y = 0 corresponding to the glyph's baseline, y < 0 to the ascending portions and y > 0 to the descending ones.
Notice that masks only use alpha values, but these don't represent opacity or luminance, but rather indices from the font's color set.
type Target ¶
type Target = *ebiten.Image
Alias to allow compiling the package without Ebitengine (-tags cputext).
Without Ebitengine, Target defaults to image/draw.Image.
