问题
I have this code that crop a portion of a image sheet.
The problem is when I use BitmapFactory.decodeResource and when log the width and height, the size is not the same as the original.
Bitmap spriteSheet = BitmapFactory.decodeResource(context.getResources(), R.drawable.imageSheet);
Log.i("Sprite Sheet Size",spriteSheet.getWidth()+"w "+spriteSheet.getHeight()+"h");
This is the log 1536w 330h but the original size of the drawable(png) is 1024x220
How do decode my resources to bitmap in their original sizes.
回答1:
The image is scaled according to the dpi of the device you are using, you can put the resources in res/drawable-nodpi or res/drawable folder to get the correct size
