bitmap

问题 I have a black and white bitmap image shown here: The image size is 200,158.

Any pointers would be greatly appreciated. 回答1: As stated in

问题 I have a problem with WPF's anti aliasing of text. In my application the user designs text or image fields to be printed using a special printing device.

问题 I am creating an Android app in which you copy an image from location x to location y . After the copying is complete I would like to see the picture in a ImageView .
