Functions

func Barcode

func Barcode(pdf barcodePdf, code string, x, y, w, h float64, flow bool)

Barcode puts a registered barcode in the current page.

The size should be specified in the units used to create the PDF document.

Positioning with x, y and flow is inherited from Fpdf.Image().

func Register

func Register(bcode barcode.Barcode) string

Register registers a barcode but does not put it on the page. Use Barcode() with the same code to put the barcode on the PDF page.

Example
package main

import (
	"github.com/boombuler/barcode/code128"
	"github.com/jung-kurt/gofpdf"
	"github.com/jung-kurt/gofpdf/contrib/barcode"
	"github.com/jung-kurt/gofpdf/internal/example"
)

func createPdf() (pdf *gofpdf.Fpdf) {
	pdf = gofpdf.New("L", "mm", "A4", "")
	pdf.SetFont("Helvetica", "", 12)
	pdf.SetFillColor(200, 200, 220)
	pdf.AddPage()
	return
}

func main() {
	pdf := createPdf()

	fileStr := example.Filename("contrib_barcode_Register")

	bcode, err := code128.Encode("gofpdf")

	if err == nil {
		key := barcode.Register(bcode)
		barcode.Barcode(pdf, key, 15, 15, 100, 10, false)
	}

	err = pdf.OutputFileAndClose(fileStr)
	example.Summary(err, fileStr)
}
Output:

Successfully generated ../../pdf/contrib_barcode_Register.pdf

func RegisterCodabar

func RegisterCodabar(pdf barcodePdf, code string) string

RegisterCodabar registers a barcode of type Codabar to the PDF, but not to the page. Use Barcode() with the return value to put the barcode on the page.

Example
package main

import (
	"github.com/jung-kurt/gofpdf"
	"github.com/jung-kurt/gofpdf/contrib/barcode"
	"github.com/jung-kurt/gofpdf/internal/example"
)

func createPdf() (pdf *gofpdf.Fpdf) {
	pdf = gofpdf.New("L", "mm", "A4", "")
	pdf.SetFont("Helvetica", "", 12)
	pdf.SetFillColor(200, 200, 220)
	pdf.AddPage()
	return
}

func main() {
	pdf := createPdf()

	key := barcode.RegisterCode128(pdf, "codabar")
	barcode.Barcode(pdf, key, 15, 15, 100, 10, false)

	fileStr := example.Filename("contrib_barcode_RegisterCodabar")
	err := pdf.OutputFileAndClose(fileStr)
	example.Summary(err, fileStr)
}
Output:

Successfully generated ../../pdf/contrib_barcode_RegisterCodabar.pdf

func RegisterCode128

func RegisterCode128(pdf barcodePdf, code string) string

RegisterCode128 registers a barcode of type Code128 to the PDF, but not to the page. Use Barcode() with the return value to put the barcode on the page.

Example
package main

import (
	"github.com/jung-kurt/gofpdf"
	"github.com/jung-kurt/gofpdf/contrib/barcode"
	"github.com/jung-kurt/gofpdf/internal/example"
)

func createPdf() (pdf *gofpdf.Fpdf) {
	pdf = gofpdf.New("L", "mm", "A4", "")
	pdf.SetFont("Helvetica", "", 12)
	pdf.SetFillColor(200, 200, 220)
	pdf.AddPage()
	return
}

func main() {
	pdf := createPdf()

	key := barcode.RegisterCode128(pdf, "code128")
	barcode.Barcode(pdf, key, 15, 15, 100, 10, false)

	fileStr := example.Filename("contrib_barcode_RegisterCode128")
	err := pdf.OutputFileAndClose(fileStr)
	example.Summary(err, fileStr)
}
Output:

Successfully generated ../../pdf/contrib_barcode_RegisterCode128.pdf

func RegisterCode39

func RegisterCode39(pdf barcodePdf, code string, includeChecksum, fullASCIIMode bool) string

RegisterCode39 registers a barcode of type Code39 to the PDF, but not to the page. Use Barcode() with the return value to put the barcode on the page.

includeChecksum and fullASCIIMode are inherited from code39.Encode().

Example
package main

import (
	"github.com/jung-kurt/gofpdf"
	"github.com/jung-kurt/gofpdf/contrib/barcode"

	key := barcode.RegisterCode39(pdf, "CODE39", false, true)
	barcode.Barcode(pdf, key, 15, 15, 100, 10, false)

	fileStr := example.Filename("contrib_barcode_RegisterCode39")
	err := pdf.OutputFileAndClose(fileStr)
