Problems solved by technology

Microchip's PIC single-chip microcomputer can be added to the wireless module to realize the mutual sending of short messages between any two machines, and the text messages can be edited like ordinary mobile phones. Use the universal name ("WDX") to realize one-to-many communication. The human-computer interface of the whole system is friendly, similar to the feature phone system, and there are operation prompts, but the SMS module does not realize the sending and receiving and display of color vector fonts.

Embodiment Construction

[0018] The method for discoloration processing of embedded vector fonts of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] An embedded vector font color-changing processing method, the specific process is as follows, the sending and receiving parties of the short message use the same short message coding method, when the user writes a short message, the user's embedded system adds the color information of the short message to the coding information of the short message, and then Send the coded information to the embedded system of the other party, after the embedded system of the other party receives the coded information, analyze and obtain the corresponding color information and text message content, and then perform the following steps to process all characters in the text message content,

[0020] Step 1, using the font engine to process the character to obtain the 256 gray level bitmap i...

Abstract

The invention discloses an embedded vector font color changing method for realizing the receiving and transmitting and displaying of multimedia messages in an embedded system with low processing capacity and low storage capacity. A message receiving party and a message transmitting party use same message coding mode. The embedded vector font color changing method comprises the following steps: adding color information of a message into coding information of the message when a user writes the message, then sending the coding information to a called user, obtaining corresponding color information and character information by analyzing after the called user receives the coding information, then executing the following steps to process all characters in the message, processing the characters by using a font engine to obtain 256-grayscale bitmap information and color information of the characters; converting the data of each point of the bitmap information according to the 256-grayscale bitmap information and the color information; and displaying the characters on a screen by using a vector font decoder according to the obtained color information.

Description

technical field [0001] The invention relates to an embedded system-oriented color-changing processing method for embedded vector fonts. Background technique [0002] As a convenient and low-cost instant messaging method, SMS stands out among many communication methods and is used more and more. In embedded systems, such as mobile phones, users can easily send and receive text messages through the SMS module of the mobile phone. Similarly, some embedded systems built with single-chip microcomputers or embedded MCUs as the core also have SMS modules. to send and receive text messages. With the wide application of SMS, users are no longer satisfied with dot matrix Chinese characters with a single color, but hope to use the color display of vector fonts with gradient effects, and the color of the SMS allows the sender to set it, that is, the SMS module of the recipient can Display the SMS content in the format of font color, font size, font shape and other formats set by the s...
