draw2d pdf
Package draw2dpdf provides a graphic context that can draw vector graphics and text on pdf file with the gofpdf package.
Quick Start
The following Go code generates a simple drawing and saves it to a pdf document:
// Initialize the graphic context on an RGBA image
dest := draw2dpdf.NewPdf("L", "mm", "A4")
gc := draw2dpdf.NewGraphicContext(dest)
// Set some properties
gc.SetFillColor(color.RGBA{0x44, 0xff, 0x44, 0xff})
gc.SetStrokeColor(color.RGBA{0x44, 0x44, 0x44, 0xff})
gc.SetLineWidth(5)
// Draw a closed shape
gc.MoveTo(10, 10) // should always be called first for a new path
gc.LineTo(100, 50)
gc.QuadCurveTo(100, 10, 10, 10)
gc.Close()
gc.FillStroke()
// Save to file
draw2dpdf.SaveToPdfFile("hello.pdf", dest)
