Functions

func RegisterFile

func RegisterFile(fpdf *gofpdf.Fpdf, imgName string, options gofpdf.ImageOptions, tiffFileStr string) (info *gofpdf.ImageInfoType)

RegisterFile registers a TIFF image, adding it to the PDF file but not adding it to the page. imgName specifies the name that will be used in the call to Image() that actually places the image in the document. options specifies various image properties; in this case, the ImageType property should be set to "tiff". The TIFF image is read from the file specified by tiffFileStr.

Example

ExampleRegisterFile demonstrates the loading and display of a TIFF image.

package main

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

func main() {
	pdf := gofpdf.New("L", "mm", "A4", "")
	pdf.SetFont("Helvetica", "", 12)
	pdf.SetFillColor(200, 200, 220)
	pdf.AddPageFormat("L", gofpdf.SizeType{Wd: 200, Ht: 200})
	opt := gofpdf.ImageOptions{ImageType: "tiff", ReadDpi: false}
	_ = tiff.RegisterFile(pdf, "sample", opt, "../../image/golang-gopher.tiff")
	pdf.Image("sample", 0, 0, 200, 200, false, "", 0, "")
	fileStr := example.Filename("Fpdf_Contrib_Tiff")
	err := pdf.OutputFileAndClose(fileStr)
	example.Summary(err, fileStr)
}
Output:

Successfully generated ../../pdf/Fpdf_Contrib_Tiff.pdf
