C++ to PostScript Library

Description:

This is a C++ to PostScript library that allows users to define shapes from our shape language in C++, and output drawings of the shapes in PostScript.
Compiling the listed files will output sample PostScript code to 'testShapes.ps' which can be interpreted by a PostScript viewer.

Shape Language + Examples:

Basic Shapes:

Circle(double radius) - Creates a circle with a given radius.
Polygon(int numSides, double sideLength) - Creates a polygon with given number of sides and side length.
Rectangle(double width, double height) - Creates a rectangle with given width and height.
Spacer(double width, double height) - Creates a spacer(rectangle) with given width and height that is not drawn to the page.
Square(double sideLength) - Creates a square with given side length.
Triangle(double sideLength) - Creates a triangle with given side length.
RainbowBall(double radius, double r, double g, double b) - Creates a spirograph-like circle in a user controlled color gradient.

Compound Shapes:

Compound shapes can be built from basic shapes or compound shapes themselves.

Rotated(Shape shape, double RotationAngle) - Creates a given shape rotated counterclockwise by the given angle.
Scaled(Shape shape, double horScale, double vertScale) - Creates a given shape scaled horizontally and vertically by the given factors.
Layered(std::initializer_list<std::shared_ptr>shape) - Creates a shape consisting of the given shapes around the current point.
Vertical(std::initializer_list<std::shared_ptr>shape) - Creates a shape consisting of the given shapes grouped vertically.
Horizontal(std::initializer_list<std::shared_ptr>shape) - Creates a shape consisting of the given shapes grouped horizontally.

Output to PostScript File Example:

Create as many shape objects from the shape language that you want to draw. Circle circle(20);
Then, create a page object to draw the shapes to the page at a specified point.

Circle circle(20);
Page shapePage;
shapePage.drawToPage(circle, 40, 40);

Finally, create a PSOutput object to add the page drawn to and specify where to output PostScript code (must be .ps file).

PSOutput output;
output.addPage(shapePage);
output.PSOutput_File("shapes.ps");
