Basic geometric transformation and Transformation Matrix Basic ry transformations are geometric transformations relative to the coordinate origin and coordinate axes, including translation, scale, rotation, reflection, and miscutting. 1.1 translation Transformation It refers to the process of moving point P from one coordinate position to another along a straight line path.

Coordinate of image translation, then, calculate the distance between them at the starting point of the set to obtain the two parameter values sx and sy to be translated by the Bitmap object. This also includes the check code that ensures that the image does not cross the View boundary. SavePreviousResult () saves the current Translation Data. Next time, you can continue to translate Bitmap Objects Based on the next translation. ZoomIn () obtains the

Algorithm Description:The algorithm steps of the 4-connected boundary filling algorithm for the stack structure are:Seed pixel into the stack, repeat the following three steps when the stack is not empty:(a) stack top pixel stack;(b) Place the stack pixel into a fill color;(c) Check out the 4-adjacency point of the stack pixel, if one of the pixels is not a boundary color and is not set to polygon color, then the pixel into the stack.Comments: Code written by the comparison, using C, but also mi

magnification is detected. Bitmap can be scaled up and translated on a View based on a Matrix object. A Matrix object is a Matrix used in android to implement geometric transformation of images. It supports common operations such as translation, amplification, reduction, miscutting, and rotation. Update and display of Bitmap objects in View By reloading the onDraw method, you can use canvas to draw Bitmap objects and use the view. invalidate () method to refresh views. Description of import
