我需要从数据库中读取文本/字符串并将它们转换为图像。我尝试了以下代码,但我只得到空白图像。请帮忙
public Bitmap textAsBitmap(String text, float largest, int textColor) {
Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL);
paint.setColor(textColor);
// int width = (int) (paint.measureText(text) + 0.5f); // round
paint.setAntiAlias(true);
paint.setTypeface(Typeface.MONOSPACE);
paint.setTextSize(16);
int width = 400;
// float baseline = (int) (paint.ascent() + 0.5f) + 3f;
// int height = (int) ((baseline + paint.descent() + 0.5f) + 3);
int height = 400;
Bitmap image = Bitmap.createBitmap(width, height,
Bitmap.Config.RGB_565);
Canvas canvas = new Canvas(image);
canvas.drawText(text, 0, 5, paint);
return image;
}
