在左下角的位图上绘制文本
Draw text on bitmap in the bottom left corner
无论位图大小如何不同,我都试图在固定位置(左下角)的位图上绘制一些文本。
下面的代码有效,但是文本绘制在位图的中心
public Bitmap drawTextToBitmap(Context gContext,
Bitmap bitmap,
String gText) {
Resources resources = gContext.getResources();
float scale = resources.getDisplayMetrics().density;
android.graphics.Bitmap.Config bitmapConfig =
bitmap.getConfig();
if (bitmapConfig == null) {
bitmapConfig = android.graphics.Bitmap.Config.ARGB_8888;
}
bitmap = bitmap.copy(bitmapConfig, true);
Canvas canvas = new Canvas(bitmap);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setColor(getResources().getColor(R.color.fujiColor));
paint.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/DS-DIGI.TTF"));
paint.setTextSize((int) (14 * scale));
paint.setShadowLayer(1f, 0f, 1f, getResources().getColor(R.color.fujiShadowColor));
Rect bounds = new Rect();
paint.getTextBounds(gText, 0, gText.length(), bounds);
int x = (bitmap.getWidth() - bounds.width()) / 2;
int y = (bitmap.getHeight() + bounds.height()) / 2;
canvas.drawText(gText, x, y, paint);
return bitmap;
}
我需要的是类似这样的东西:
谢谢。
正如official docs中提到的,文本是以(x,y)值作为原点绘制的。更改 x
、y
值。按照以下几行应该可以工作。
int horizontalSpacing = 24;
int verticalSpacing = 36;
int x = horizontalSpacing;//(bitmap.getWidth() - bounds.width()) / 2;
int y = bitmap.getHeight()-verticalSpacing;//(bitmap.getHeight() + bounds.height()) / 2;
