class dcGraphicsState

Each instance holds the current graphics state. It can be saved (pushed) and restored (popped) by the owning parent

Methods

---

__init__(self)

Creates an instance with default values

---

Get_angle(self)

Return rotation angle in degrees

---

Get_x(self, x=0, y=0)

Return x co-ordinate using graphic states and transforms Input x,y are current co-ords

---

Get_y(self, x=0, y=0)

Return y co-ordinate using graphic states and transforms Input x,y are current co-ords

---

Rotate(self, cosA, sinA)

Compute the (text only) rotation angle sinA is inverted to cancel the original inversion in pdfviewer.drawfile that was introduced because of the difference in y direction between pdf and GraphicsContext co-ordinates

---

Scale(self, sx, sy)

scale the current co-ordinates

---

Skew(self, tanAlpha, tanBeta)

---

Translate(self, dx, dy)

move the origin from the current point to (dx,dy)

---

Ytop(self, y)

Return y co-ordinate wrt top of current page
