Embodiment Construction
[0019] In order to make the technical means, creative features and objectives of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific examples
[0020] like figure 1 As shown, a graph caching method for transposition of vector graphics, the specific steps of the method are:
[0021] Step 1. According to different requirements, store the vector diagram in the program in the vector diagram storage module 1, a local file or use code to draw.
[0022] Step 2. When the application program needs to use a certain image, draw the corresponding vector diagram, and send the obtained vector diagram to the vector diagram conversion bitmap module 2 .
[0023] Step 3, vector graphics conversion bitmap module 2 performs some display optimization on the vector graphics, intelligently improves or reduces the brightness, contrast, and sharpness of the image; and then converts it into a bitmap.
[0024] Step 4, the vector...

The invention discloses a caching method for a vector diagram converted bitmap and a special image processing device. The caching method comprises the steps of: storing a vector diagram into a vector diagram storage module based on different demands; drawing a corresponding vector diagram; carrying out optimization in the aspect of display for the vector diagram by a vector diagram-to-bitmap conversion module; handing in the well converted bitmap to a bitmap caching module by the vector diagram-to-bitmap conversion module; deleting unnecessary bitmaps from an internal memory; and obtaining necessary images from the bitmap caching module by the bitmap display module. The special image processing device comprises a vector diagram storage module, a vector diagram-to-bitmap conversion module, a bitmap caching module and a bitmap display module, wherein the output end of the vector diagram storage module is connected to the input end of the vector diagram-to-bitmap conversion module; the output end of the vector diagram-to-bitmap conversion module is connected to the input end of the bitmap caching module; and the output end of the bitmap caching module is connected to the input end of the bitmap display module. According to the invention, the size of the application is reduced to a relatively great extent.
Description
technical field [0001] The invention relates to a caching method of a vector diagram transposed image, in particular to a caching method of a vector diagram transposed image and a special image processing device thereof. Background technique [0002] Currently, graphical user interfaces are increasingly used on mobile devices. However, the use of other image processing technologies will result in the phenomenon that the final generated program is too large or the program does not run smoothly; the traditional image caching technology has low operating efficiency and takes up a large storage space. Contents of the invention [0003] In order to overcome the defects in the above-mentioned prior art, the present invention provides a vector graphics transposition bitmap caching method applied to mobile device development and a special image processing device thereof, the method greatly reduces the size of the application program, and the device Significantly reduce the size o...
