PHP Image水印不支持高棉字体Unicode 缺少字体结果

如何解决PHP Image水印不支持高棉字体Unicode 缺少字体结果

我在laravel项目中使用https://github.com/Intervention/image在图像上生成水印。我从https://fonts.google.com和https://github.com/osify/cambodianfonts/tree/master/Unicode/Compartible-with-Photoshop-CS3下载并使用了两种字体。

我写了代码

            $textFont = public_path('Khmer/Khmer-Regular.ttf');
            $template = Image::make($this->disk->path($user->avatar));
            $text = "កម្ពុជា";
            $template->text($text,190,600,function ($font) use ($textFont) {
                $font->file($textFont);
                $font->size(30);
                $font->color('#bc1f1f');
                //  $font->align('center');
                $font->valign('top');
                $font->angle(0);
            });

缺少字体结果

因此，请帮助建议任何代码或解决方案。

注意*我也阅读并关注 How to recognize khmer unicode in intervention images?

https://github.com/Intervention/image/issues/702

但这也不是解决方案。 和

解决方法

我也尝试使用KH字体，但是它不起作用。 我的解决方案：

1. NodeJS（text2png）从高棉Unicode创建图像。

const express = require('express');
const text2png = require('text2png');
const path = require('path');
const app = express();

app.get('/image',function (req,res) {
    const buffer = text2png('ប្រទេសកម្ពុជា',{
            color: 'red',font: '80px Bokor',localFontPath: path.join(__dirname,'/../public/fonts/Kh-Bokor.ttf'),localFontName: 'Bokor',output: 'buffer'
        });

    return res.status(200).send(buffer)
});

app.listen(3000,function () {
    console.log("Express run on port: 3000");
})

1. 从PHP发送请求并合并两个图像

$data = Http::get('http://localhost:3000/image');

$body = $data->body();

$watermark = Image::make($body);

$image = Image::make(public_path() . "/images/cam.jpg");
$image->insert($watermark,'center');
$image->save('image.png');

Here is Result

我真的想使用唯一的PHP。

如果我使用Java与下面的代码配合得很好。

@RestController
@RequestMapping("image")
public class ImageGenerateController {
    final static  String UPLOAD = "";

    @PostMapping(value = "/generate")
    public ResponseEntity<?> generate(@Valid @RequestBody ImagePayload request) throws Exception {

        ByteBuffer buffer = StandardCharsets.UTF_8.encode(request.getTitle());

        String utf8EncodedString = StandardCharsets.UTF_8.decode(buffer).toString();
        try {
            BufferedImage img = stringToBufferedImage(utf8EncodedString);
            System.out.println(img);
            File file = new File(UPLOAD + request.getName() + ".png");
            ImageIO.write(img,"png",file);
            String mmm = "ពិតជាអស្ចារ្យណាស់";
            return ResponseEntity.ok(mmm);

        } catch (IOException ex) {
            ex.printStackTrace();
        }
        return ResponseEntity.badRequest().body("Missing something");

    }

    public BufferedImage stringToBufferedImage(String value) {
        //First,we have to calculate the string's width and height

        BufferedImage img = new BufferedImage(1,1,BufferedImage.TYPE_4BYTE_ABGR);
        Graphics g = img.getGraphics();

        //Set the font to be used when drawing the string
        Font f = new Font("Khmer OS",Font.PLAIN,48);
        g.setFont(f);

        //Get the string visual bounds
        AttributedString attributedText = new AttributedString(value);
        attributedText.addAttribute(TextAttribute.FONT,f);
        attributedText.addAttribute(TextAttribute.FOREGROUND,Color.GREEN);

        FontRenderContext frc = g.getFontMetrics().getFontRenderContext();
        Rectangle2D rect = f.getStringBounds(value,frc);
        //Release resources
        g.dispose();

        //Then,we have to draw the string on the final image

        //Create a new image where to print the character
        img = new BufferedImage((int) Math.ceil(rect.getWidth()),(int) Math.ceil(rect.getHeight()),BufferedImage.TYPE_4BYTE_ABGR);
        g = img.getGraphics();
        g.setColor(Color.black);
        //Otherwise the text would be white
        g.setFont(f);

        //Calculate x and y for that string
        FontMetrics fm = g.getFontMetrics();
        int x = 0;
        int y = fm.getAscent(); //getAscent() = baseline
        g.drawString(attributedText.getIterator(),x,y);

        //Release resources
        g.dispose();

        //Return the image
        return img;
    }
}
