RadialBlit

Radial gradient blitter struct.

You set up the properties and pass the BlitFunc to the rasterizer.

auto ablit = RadialBlit(m_pixels,m_stride,m_height);
rblit.setPaint(grad, wr, RepeatMode.Pad);
rblit.setCoords(x0,y0,x1,y1,x2,y2);
m_rasterizer.rasterize(rblit.getBlitFunc);

struct RadialBlit {

this(uint* pixels, int stride, int height);

void setPaint(Gradient grad, WindingRule wrule, RepeatMode rmode);

void setCoords(float x0, float y0, float x1, float y1, float x2, float y2);

void setCoords(float x0, float y0, float x1, float y1);

BlitFunc getBlitFunc();

}

this this(uint* pixels, int stride, int height): Construct a Radial blitter. pixels - pointer to a 32 bpp pixel buffer stride - buffer width in pixels height - buffer heigth in pixels

Functions

getBlitFunc BlitFunc getBlitFunc(): returns a BlitFunc for use by the rasterizer
setCoords void setCoords(float x0, float y0, float x1, float y1): Specifiy the orientation in terms of an circle, for that we need two points, (x0,y0) is the center of the circle (x1,y1) is radius at 0 degrees
setCoords void setCoords(float x0, float y0, float x1, float y1, float x2, float y2): Specifiy the orientation in terms of an elipse, for that we need 3 points... (x0,y0) is the center of the elipse (x1,y1) is radius at 0 degrees (x2,y2) is radius at 90 degrees The radii dont need to be at right angles, so it can handle elipse that has been though any affine transform.
setPaint void setPaint(Gradient grad, WindingRule wrule, RepeatMode rmode): set the gradient, winding rule and repeat mode. "numRepeats" sets how many times the gradient repeats in 360 degrees.
