添加水印图像中的android

问题描述

我有code添加水印的图像像这样

I have code to add watermark in image like this

public static Bitmap mark(Bitmap src, String watermark, Point location, Color color, int alpha, int size, boolean underline) {
            int w = src.getWidth();
            int h = src.getHeight();
            Bitmap result = Bitmap.createBitmap(w, h, src.getConfig());

            Canvas canvas = new Canvas(result);
            canvas.drawBitmap(src, 0, 0, null);

            Paint paint = new Paint();
            paint.setColor(color.RED);
            paint.setAlpha(alpha);
            paint.setTextSize(size);
            paint.setAntiAlias(true);
            paint.setUnderlineText(underline);
            canvas.drawText(watermark, location.x, location.y, paint);

            return result;
        }

和我称这个code的作用

and I call that function with this code

mark(bitmap, "watermark", b, null, c, 100, false);
            imgshoot.setImageBitmap(bitmap);

但没有发生，u能帮助我吗？谢谢

推荐答案

它解决了，我只是改变了乌拉圭回合的建议Doomsknight小为code和感谢：）

it solved , I just change little for that code , and thanks for ur advice Doomsknight :)

 public static Bitmap mark(Bitmap src, String watermark) {
            int w = src.getWidth();
            int h = src.getHeight();
            Bitmap result = Bitmap.createBitmap(w, h, src.getConfig());
            Canvas canvas = new Canvas(result);
            canvas.drawBitmap(src, 0, 0, null);
            Paint paint = new Paint();
            paint.setColor(Color.RED);
            paint.setTextSize(18);
            paint.setAntiAlias(true);
            paint.setUnderlineText(true);
            canvas.drawText(watermark, 20, 25, paint);

            return result;
        }

和我有此函数调用

bitmap = mark(bitmap, "Hallo");

            imgshoot.setImageBitmap(bitmap);
