Tried to render hindi font
import (
"image"
"image/color"
"image/png"
"os"
"golang.org/x/image/font"
"golang.org/x/image/font/opentype"
"golang.org/x/image/math/fixed"
)
func addLabel(img *image.RGBA, x, y int, label string, fontPath string, fontSize float64) {
col := color.RGBA{200, 100, 0, 255}
fontData, err := os.ReadFile(fontPath)
if err != nil {
panic(err)
}
f, err := opentype.Parse(fontData)
if err != nil {
panic(err)
}
face, err := opentype.NewFace(f, &opentype.FaceOptions{
Size: fontSize,
DPI: 72,
Hinting: font.HintingNone,
})
if err != nil {
panic(err)
}
point := fixed.Point26_6{X: fixed.I(x), Y: fixed.I(y)}
d := &font.Drawer{
Dst: img,
Src: image.NewUniform(col),
Face: face,
Dot: point,
}
d.DrawString(label)
}
func saveImg() {
img := image.NewRGBA(image.Rect(0, 0, 300, 100))
// fontPath := "assets/fonts/Helvetica.ttf"
// fontSize := 50.0
// addLabel(img, 20, 50, "Hello Go", fontPath, fontSize)
fontPath := "assets/fonts/mangal.ttf"
fontSize := 50.0
addLabel(img, 20, 50, "नमस्ते", fontPath, fontSize)
f, err := os.Create("hello-go.png")
if err != nil {
panic(err)
}
defer f.Close()
if err := png.Encode(f, img); err != nil {
panic(err)
}
}What did you see happen?
fonts are not being able to render properly. I had the same problem in python and they included libraqm which fixed the issue i wish if we have something for golang too
What did you expect to see?
Output
Expected
