### Generate PDFs with Nonstandard Fonts using go-pdf/fpdf

Source: https://github.com/go-pdf/fpdf/blob/main/doc/document.md

Demonstrates adding and using non-UTF-8 TrueType or Type1 fonts in PDF generation with go-pdf/fpdf. This requires generating a font definition file and potentially a compressed font file using the MakeFont utility. Once processed, the AddFont method loads the font, and SetFont is used to start using it.

```shell
./makefont --embed --enc=../font/cp1252.map --dst=../font ../font/calligra.ttf
```

```Go
// AddFont loads the font definition file.
pdf.AddFont("calligra", "", "../font/calligra.ttf")

// SetFont begins using the loaded font.
pdf.SetFont("calligra", "", 12)
```

### Generate Simple PDF with GoFPDF

Source: https://github.com/go-pdf/fpdf/blob/main/doc/document.md

Demonstrates how to create a basic PDF file using the GoFPDF library. It initializes a new PDF document, sets the font, adds a 'Hello, world' cell, and saves the output to a file.

```go
pdf := fpdf.New("P", "mm", "A4", "")
pdf.AddPage()
pdf.SetFont("Arial", "B", 16)
pdf.Cell(40, 10, "Hello, world")
err := pdf.OutputFileAndClose("hello.pdf")
```

### Switch Text Direction with RTL() and LTR() in go-pdf/fpdf

Source: https://github.com/go-pdf/fpdf/blob/main/doc/document.md

Illustrates how to switch text rendering between right-to-left (RTL) and left-to-right (LTR) modes when working with UTF-8 encoded fonts in the go-pdf/fpdf library. This is crucial for languages that require specific text directionality.

```Go
// Switch to Right-to-Left mode
pdf.RTL()

// Switch to Left-to-Right mode
pdf.LTR()
```
