Member Function Documentation
| virtual void iPen::ClearFlag | ( | uint | flag | ) |  [pure virtual] | 
| virtual void iPen::ClearTransform | ( | ) |  [pure virtual] | 
| 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::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::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::PopTransform | ( | ) |  [pure virtual] | 
Pops the transform stack.
The top of the stack becomes the current transform.
Implemented in csPen, and csMemoryPen.
