Cyrrilic text for image

[shahmuratov]

Hello! I need to create cyrillic text in image but all I can get is squares. Here is my code

package main

import (
    "github.com/jung-kurt/gofpdf"
    "github.com/golang/freetype"
    "image"
    "fmt"
    "os"
    "bytes"
    "image/jpeg"
    "io/ioutil"
    "image/draw"
)

func main() {
    pwd, err := os.Getwd()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }
    dataFont, err := ioutil.ReadFile(pwd + "/font/luxisr.ttf")
    if err != nil {
        fmt.Printf("%v",err)
    }
    f, err := freetype.ParseFont(dataFont)
    if err != nil {
        fmt.Printf("%v",err)
    }
    dst := image.NewRGBA(image.Rect(0, 0, 800, 600))
    draw.Draw(dst, dst.Bounds(), image.White, image.ZP, draw.Src)
    c := freetype.NewContext()
    c.SetDst(dst)
    c.SetClip(dst.Bounds())
    c.SetSrc(image.Black)
    c.SetFont(f)
    c.DrawString("русский текст", freetype.Pt(0, 16))
    pdf := gofpdf.New("P", "mm", "A4", "")
    pdf.AddPage()
    buf := new(bytes.Buffer)
    err = jpeg.Encode(buf, dst, nil)

    if err != nil {
        fmt.Printf("%v",err)
    }

    reader := bytes.NewReader(buf.Bytes())
    textName := "text1"
    pdf.RegisterImageReader(textName, "jpg", reader)
    pdf.Image(textName, 15, 15, 0, 0, false, "jpg", 0, "")
    pdf.OutputFileAndClose("test.pdf")
}

Use a different font. The luxisr.ttf that is bundled wirth freetype doen't seem to contain a lot of symbols.
If I use your program with a different font (I tried Roboto.ttf from Google fonts), the cyrillic text renders fine.

Shameless plug: a simple way to locate myfont.ttf on your system is findfont.Find("myfont.ttf") from https://github.com/flopp/go-findfont ;)

Yeah, use a different font.
