Practical development tips for Windows Phone (16): editing images in Windows Phone

When it comes to editing images, you may think of splitting the images into pixels and then operating these pixels to edit the images. Today we will introduce a useful class called writeablebitmap, a class that can save the UI elements as images or save the UI elements after they are converted. OK. Let's start the demo:

It is implemented in two ways: UI and postCode.

Ui implementation:

For page layout, convert the image control and textblock control into a container (I select grid)

 

The general XAML is as follows, where grid is named xamlgrid

Next let's take a look at how the event is handled. First, save the UI element as a writable image, then save it to the state, and display it on another page:

Page 2 accept and display

The running effect is as follows:

Next, let's take a look at the second method,Post-code implementationThis method may be more practical in practical application:

The method is very simple, that is, to translate the previous XAML in The Post code.
