之前介绍过使用 FreeType-go 来绘制字 现在相关的包被做了整合,主要是整合到了 github.com/golang/freetype 和 golang.org/x/image/font 这里了,所以就有了这篇博客。
例子代码在: https://github.com/golang/freetype/blob/master/example/freetype/main.go
package main
import (
"bufio"
"flag"
"fmt"
"image"
"image/color"
"image/draw"
"image/png"
"io/ioutil"
"log"
"os" "github.com/golang/freetype"
"golang.org/x/image/font"
)var (
dpi = flag.Float64("dpi", 72, "screen resolution in Dots Per Inch")
fontfile = flag.String("fontfile", "../../testdata/luxisr.ttf", "filename of the ttf font")
hinting = flag.String("hinting", "none", "none | full")
size = flag.Float64("size", 12, "font size in points")
spacing = flag.Float64("spacing", 1.5, "line spacing (e.g. 2 means double spaced)")
wonb = flag.Bool("whiteonblack", false, "white text on a black background")
)var text = []string{
"’Twas brillig, and the slithy toves",
"测试中文字 ……&^_^",
"Did gyre and gimble in the wabe;",
"All mimsy were the borogoves,",
"And the mome raths outgrabe.",
"",
"“Beware the Jabberwock, my son!",
"The jaws that bite, the claws that catch!",
"Beware the Jubjub bird, and shun",
"The frumious Bandersnatch!”",
"",
"He took his vorpal sword in hand:",
"Long time the manxome foe he sought—",
"So rested he by the Tumtum tree,",
"And stood awhile in thought.",
"",
"And as in uffish thought he stood,",
"The Jabberwock, with eyes of flame,",
"Came whiffling through the tulgey wood,",
"And burbled as it came!",
"",
"One, two! One, two! and through and through",
"The vorpal blade went snicker-snack!",
"He left it dead, and with its head",
"He went galumphing back.",
"",
"“And hast thou slain the Jabberwock?",
"Come to my arms, my beamish boy!",
"O frabjous day! Callooh! Callay!”",
"He chortled in his joy.",
"",
"’Twas brillig, and the slithy toves",
"Did gyre and gimble in the wabe;",
"All mimsy were the borogoves,",
"And the mome raths outgrabe.",
}func main() {
flag.Parse() // Read the font data.
fontBytes, err := ioutil.ReadFile(*fontfile)
if err != nil {
log.Println(err)
return
}
f, err := freetype.ParseFont(fontBytes)
if err != nil {
log.Println(err)
return
} // Initialize the context.
fg, bg := image.Black, image.White
ruler := color.RGBA{0xdd, 0xdd, 0xdd, 0xff}
if *wonb {
fg, bg = image.White, image.Black
ruler = color.RGBA{0x22, 0x22, 0x22, 0xff}
}
rgba := image.NewRGBA(image.Rect(0, 0, 640, 480))
draw.Draw(rgba, rgba.Bounds(), bg, image.ZP, draw.Src)
c := freetype.NewContext()
c.SetDPI(*dpi)
c.SetFont(f)
c.SetFontSize(*size)
c.SetClip(rgba.Bounds())
c.SetDst(rgba)
c.SetSrc(fg)
switch *hinting {
default:
c.SetHinting(font.HintingNone)
case "full":
c.SetHinting(font.HintingFull)
} // Draw the guidelines.
for i := 0; i >6))
for _, s := range text {
_, err = c.DrawString(s, pt)
if err != nil {
log.Println(err)
return
}
pt.Y += c.PointToFixed(*size * *spacing)
} // Save that RGBA image to disk.
outFile, err := os.Create("out.png")
if err != nil {
log.Println(err)
os.Exit(1)
}
defer outFile.Close()
b := bufio.NewWriter(outFile)
err = png.Encode(b, rgba)
if err != nil {
log.Println(err)
os.Exit(1)
}
err = b.Flush()
if err != nil {
log.Println(err)
os.Exit(1)
}
fmt.Println("Wrote out.png OK.")
}
执行效果如下:
./testFont2 -fontfile=”字体管家淘淘体.ttf”
执行效果:
./testFont2 -fnotallow=”6f14c8f349377d5ebe2b0a5e2851a6f6.ttf”
执行效果:
./testFont2 -fnotallow=”Sliced by Hand.ttf”
执行效果,这个字体不支持中文,就会出现下面情况:

问题:怎么批量删除Word表里的空格 解决: 如果真的是空格,查找替换就可以了,但是首先需要确定,“空格”真的是空格吗? 从下图可以看出,本示例中的“空格”,实际是【首行缩进】。 如果需要修改的地方较少,手动调整首行缩进符即可;或者选取整个表,在【开始】选项卡…
