For example, we can specify that a pixel will take 32 bits (ARGB_8888), as such each red, green, blue color will take 8 bits, and the alpha channel will take 8 bits. The configuration specify the number of bits that each pixel in the bitmap will have. It also takes the configuration for this Bitmap. This method will take as parameters the width and height of the bitmap in pixels. Bitmap.createBitmap(int width, int height, Bitmap.Config config)

Comments are added inside the code to understand the code in more detail. This function is called in the main code to convert the vector image to bitmap form. In the code, we implemented a function that takes in the vector location and processes into a bitmap. These methods will allow us to set the width, height, density, and number of pixels of a Bitmap. Step 4: Working with the MainActivity.kt file. The Bitmap class has many methods that allow us to create an instance of a Bitmap by using java. Below is the code for the activitymain.xml file. of the drawn shape using the paint object. Next, go to the activitymain.xml file, which represents the UI of the project.

anew ArrayList() // a.add(bm1).

What is paint ?Ī paint object is an instance of the Paint class. We can style the shapes created by the canvas by using a paint object. Such as drawing a text, a line, a rectangle or a circle. Bitmap. A canvas is used to draw on a bitmap, it has methods to draw shapes on a bitmap. method in Best Java code snippets using aphics. We can create a Bitmap instance, either by using the Bitmap class which has methods that allow us to manipulate pixels in the 2d coordinate system, or we can can create a Bitmap from an image or a file or a resource by using the BitmapFactory class What is canvas ?Ī canvas is an object which is an instance of the class Canvas.

Įverything that is drawn in android is a Bitmap. A pixel can be formed of 8, or 16 or 24 bits … The x axis represents the width, and the y axis represent the height. A pixel is formed of bits, and bits represent the color of this pixel. Įach point in the coordinate system is called a pixel. The coordinate system move to the right on the x axis, and to the bottom on the y axis. This class represents a 2d coordinate system.
