WHAT IS THIS?!?!

It's a monster. It is a base made from https://github.com/signintech/gopdf with some of the interfaces provided by https://github.com/jung-kurt/gofpdf. I highly advise you use one of these two libraries if you want reliable pdf generation in go. This has mostly been worked on for our own use cases, however both projects have benifited from this work.

func (*Fpdf) Arc 

func (gp *Fpdf) Arc(x, y, rx, ry, degRotate, degStart, degEnd float64, styleStr string)

Arc draws an elliptical arc centered at point (x, y). rx and ry specify its horizontal and vertical radii.

degRotate specifies the angle that the arc will be rotated. degStart and degEnd specify the starting and ending angle of the arc. All angles are specified in degrees and measured counter-clockwise from the 3 o'clock position.

styleStr can be "F" for filled, "D" for outlined only, or "DF" or "FD" for outlined and filled. An empty string will be replaced with "D". Drawing uses the current draw color, line width, and cap style centered on the arc's path. Filling uses the current fill color.

The Circle() example demonstrates this method.

func (*Fpdf) ArcTo 

func (gp *Fpdf) ArcTo(x, y, rx, ry, degRotate, degStart, degEnd float64)

ArcTo draws an elliptical arc centered at point (x, y). rx and ry specify its horizontal and vertical radii. If the start of the arc is not at the current position, a connecting line will be drawn.

degRotate specifies the angle that the arc will be rotated. degStart and degEnd specify the starting and ending angle of the arc. All angles are specified in degrees and measured counter-clockwise from the 3 o'clock position.

styleStr can be "F" for filled, "D" for outlined only, or "DF" or "FD" for outlined and filled. An empty string will be replaced with "D". Drawing uses the current draw color, line width, and cap style centered on the arc's path. Filling uses the current fill color.

The MoveTo() example demonstrates this method.

func (*Fpdf) Beziergon 

func (gp *Fpdf) Beziergon(pts Points, styleStr string) error

Beziergon draws a closed figure defined by a series of cubic Bézier curve segments. The first point in the slice defines the starting point of the figure. Each three following points p1, p2, p3 represent a curve segment to the point p3 using p1 and p2 as the Bézier control points.

The x and y fields of the points use the units established in New().

styleStr can be "F" for filled, "D" for outlined only, or "DF" or "FD" for outlined and filled. An empty string will be replaced with "D". Drawing uses the current draw color and line width centered on the ellipse's perimeter. Filling uses the current fill color.

func (*Fpdf) Beziertext 

func (gp *Fpdf) Beziertext(pts Points, startBracket, endBracket float64, text string, opt CellOption, textOpt TextOption) error

Beziertext writes text along a path defined by a series of cubic Bézier curve segments. Font size is reduced if the text exceeds avaiable arc length.

func (*Fpdf) Cell

func (*Fpdf) CellWithOption 

func (gp *Fpdf) CellWithOption(w, h float64, text string, opt CellOption, textOpts TextOption) error

CellWithOption create cell of text ( use current x,y is upper-left corner of cell)

func (*Fpdf) Cellf 

func (gp *Fpdf) Cellf(w, h float64, text string, args ...interface{}) error

Cellf : same as cell but using go's Sprintf format

func (*Fpdf) Circle 

func (gp *Fpdf) Circle(x, y, r float64, styleStr string)

Circle draws a circle centered on point (x, y) with radius r.

styleStr can be "F" for filled, "D" for outlined only, or "DF" or "FD" for outlined and filled. An empty string will be replaced with "D". Drawing uses the current draw color and line width centered on the circle's perimeter. Filling uses the current fill color.

func (*Fpdf) ClipCircle 

func (gp *Fpdf) ClipCircle(x, y, r float64, outline bool)

ClipCircle begins a circular clipping operation. The circle is centered at (x, y) and has radius r. outline is true to draw a border with the current draw color and line width centered on the circle's perimeter. Only the outer half of the border will be shown. After calling this method, all rendering operations (for example, Image(), LinearGradient(), etc) will be clipped by the specified circle. Call ClipEnd() to restore unclipped operations.

The ClipText() example demonstrates this method.

func (*Fpdf) ClipEllipse 

func (gp *Fpdf) ClipEllipse(x, y, rx, ry float64, outline bool)

ClipEllipse begins an elliptical clipping operation. The ellipse is centered at (x, y). Its horizontal and vertical radii are specified by rx and ry. outline is true to draw a border with the current draw color and line width centered on the ellipse's perimeter. Only the outer half of the border will be shown. After calling this method, all rendering operations (for example, Image(), LinearGradient(), etc) will be clipped by the specified ellipse. Call ClipEnd() to restore unclipped operations.

This ClipText() example demonstrates this method.

func (*Fpdf) ClipEnd 

func (gp *Fpdf) ClipEnd()

ClipEnd ends a clipping operation that was started with a call to ClipRect(), ClipRoundedRect(), ClipText(), ClipEllipse(), ClipCircle() or ClipPolygon(). Clipping operations can be nested. The document cannot be successfully output while a clipping operation is active.

The ClipText() example demonstrates this method.

func (*Fpdf) ClipPolygon 

func (gp *Fpdf) ClipPolygon(points []Point, outline bool)

ClipPolygon begins a clipping operation within a polygon. The figure is defined by a series of vertices specified by points. The x and y fields of the points use the units established in New(). The last point in the slice will be implicitly joined to the first to close the polygon. outline is true to draw a border with the current draw color and line width centered on the polygon's perimeter. Only the outer half of the border will be shown. After calling this method, all rendering operations (for example, Image(), LinearGradient(), etc) will be clipped by the specified polygon. Call ClipEnd() to restore unclipped operations.

The ClipText() example demonstrates this method.

func (*Fpdf) ClipRect 

func (gp *Fpdf) ClipRect(x, y, w, h float64, outline bool)

ClipRect begins a rectangular clipping operation. The rectangle is of width w and height h. Its upper left corner is positioned at point (x, y). outline is true to draw a border with the current draw color and line width centered on the rectangle's perimeter.

At the start point, the curve is tangent to the straight line between the start point and the control point. At the end point, the curve is tangent to the straight line between the end point and the control point.

At the start point, the curve is tangent to the straight line between the start point and the control point (cx0, cy0). At the end point, the curve is tangent to the straight line between the end point and the control point (cx1, cy1).

styleStr can be "F" for filled, "D" for outlined only, or "DF" or "FD" for outlined and filled. An empty string will be replaced with "D". Drawing uses the current draw color, line width, and cap style centered on the curve's path. Filling uses the current fill color.

This routine performs the same function as CurveCubic() but uses standard argument order.

Create a "path" by moving a virtual stylus around the page (with MoveTo, LineTo, CurveTo, CurveBezierCubicTo, ArcTo & ClosePath) then draw it or fill it in (with DrawPath). The main advantage of using the path drawing routines rather than multiple Fpdf.Line is that PDF creates nice line joins at the angles, rather than just overlaying the lines.
