Member Function Documentation

virtual void iPen::ClearFlag ( uint  flag  )  [pure virtual]

Clears the given flag.

Parameters:
flag The flag to clear.

Implemented in csPen, and csMemoryPen.

virtual void iPen::ClearTransform (  )  [pure virtual]

Clears the current transform, resets to identity.

Implemented in csPen, and csMemoryPen.

virtual void iPen::DrawArc ( uint  x1,
uint  y1,
uint  x2,
uint  y2,
float  start_angle,
float  end_angle 
) [pure virtual]

Draws an elliptical arc from start angle to end angle.

Angle must be specified in radians. The arc will be made to fit in the given box. If you want a circular arc, make sure the box is a square. If you want a full circle or ellipse, specify 0 as the start angle and 2*PI as the end angle.

Implemented in csPen, and csMemoryPen.

virtual void iPen::DrawLine ( uint  x1,
uint  y1,
uint  x2,
uint  y2 
) [pure virtual]

Draws a single line.

Implemented in csPen, and csMemoryPen.

virtual void iPen::DrawMiteredRect ( uint  x1,
uint  y1,
uint  x2,
uint  y2,
uint  miter 
) [pure virtual]

Draws a mitered rectangle.

The miter value should be between 0.0 and 1.0, and determines how much of the corner is mitered off and beveled.

Implemented in csPen, and csMemoryPen.

virtual void iPen::DrawPoint ( uint  x1,
uint  y2 
) [pure virtual]

Draws a single point.

Implemented in csPen, and csMemoryPen.

virtual void iPen::DrawRect ( uint  x1,
uint  y1,
uint  x2,
uint  y2 
) [pure virtual]

Draws a rectangle.

Implemented in csPen, and csMemoryPen.

virtual void iPen::DrawRoundedRect ( uint  x1,
uint  y1,
uint  x2,
uint  y2,
uint  roundness 
) [pure virtual]

Draws a rounded rectangle.

The roundness value should be between 0.0 and 1.0, and determines how much of the corner is rounded off.

Implemented in csPen, and csMemoryPen.

virtual void iPen::DrawTriangle ( uint  x1,
uint  y1,
uint  x2,
