Problems solved by technology
[0004] However, at present, although the Symbian platform has the following advantages: it separates the general technology of mobile devices (that is, the kernel of the operating system) from the graphical user interface technology, well adapts to different input platforms, and allows manufacturers to provide their own products. It has been widely used to create a more friendly operation interface and conform to the trend of individualization. However, because the Symbian platform is relatively primitive compared with the ios platform and the android platform, the magnifying glass function has not yet been implemented, and it is impossible to guarantee that the user can accurately select out text

Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] see figure 1 , figure 1 The basic flowchart provided for the embodiment of the present invention. Such as figure 1 As shown, the process may include the following steps:
[0026] Step 101, acquire the sliding coordinates triggered by the user on the display page.
[0027] In this step 101, the sliding coordinates are the pressed coordinates generated by the user's touch screen sliding, or each coordinate passed by the user's touch screen dragging.
[0028] It should be noted that the method provided in this embodiment is applied to mobile terminals based on the Symbian platform. And, before executing this step 101, the user can first enable the free copy function set in the mobile phone browser, and then, the text area selected by the ...

The invention provides a method and a device for realizing a magnifier based on a Symbian platform, and is characterized in that the method comprises the following steps: obtaining a sliding coordinate triggered in a display page by a user; cutting out a first area, which takes the sliding coordinate as a centre and the size as a set value, wherein the set value is decided by the size of the magnifier to be drawn; amplifying the first area, and taking the amplified first area as a style of a brush, wherein the amplification multiplying power is decided by the multiplying power allowed by the magnifier; figuring up a second area used for drawing the magnifier in the page; and drawing and displaying the magnifier on the second area by utilizing the style of the brush. By adopting the invention, the magnifier function can be realized on the Symbian platform, and a user is ensured to accurately select the required characters.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a method and a device for realizing a magnifying glass based on a Symbian platform. Background technique [0002] Because the screen of the mobile phone is relatively small, it is not easy for the user to accurately select the text he wants from the many displayed texts when many texts are displayed on the screen of the mobile phone. For example, when the user selects text by triggering with a finger, the selected area will be blocked by the finger, resulting in inaccurate text selection. [0003] In order to ensure accurate text selection, the prior art proposes a magnifying glass function. The essence of the so-called magnifying glass function is to capture an area on the page displayed on the mobile phone screen centered on the pressed coordinates generated by the user's finger sliding on the screen and the size is the set radius, to enlarge the area, and set the enlarged a...
