Drawings
The following detailed description of embodiments of the invention will be made with reference to the accompanying drawings.
Fig. 1 is a schematic view of a modular structure of a text message playing apparatus according to an embodiment of the present invention.
Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic view of a modular structure of a text information playing apparatus according to an embodiment of the present invention. As shown in fig. 1, the text information playing device includes: a font property acquiring module 110, a conversion judging module 130, a font converting module 150, a first type font library 170, and a play control module 190; the text message playing device is implemented by software, for example, and may be installed in an LED display screen system, for example, an asynchronous control card of an LED display screen asynchronous system, but the invention is not limited thereto.
Specifically, the font attribute obtaining module 110 is configured to obtain font attributes of the text information to be played, where the font attributes include attributes such as a font type, a font name, and a font size. Font types are for example: dot matrix fonts, vector fonts, and the like; the font names are for example: song Dynasty, regular script, etc.
The conversion determining module 130 is configured to determine whether font conversion is needed according to the font type in the font attribute of the text information to be played, which is obtained by the font attribute obtaining module 110. For example, when the first type font library 170 is a dot matrix font library, if the font type of the text information to be played is a vector font, the determination result of the conversion determining module 130 is that font conversion is required, otherwise, if the font type of the text information to be played is a dot matrix font, the determination result of the conversion determining module 130 is that font conversion is not required. Similarly, when the first type font library 170 is a vector font library, if the font type of the text information to be played is a dot matrix font, the determination result of the conversion determining module 130 is that font conversion is required, otherwise, if the font type of the text information to be played is a vector font, the determination result of the conversion determining module 130 is that font conversion is not required.
The font conversion module 150 is configured to scale the font size of the text information to be played according to a preset ratio when the font type of the text information to be played is the second type font and font conversion is required. For example, the conversion relationship between the vector font size and the dot matrix font size is preferably: vector font size = dot matrix font size 3/4, dot matrix font size = vector font size 4/3.
The playing control module 190 is configured to find a matched first type font from the first type font library 170 according to the font name of the text information to be played and the scaled font size, and control the text information to be played in the matched first type font for playing and displaying; and in the case of no font conversion, the method and the device are configured to find out the matched first type font from the first type font library 170 according to the font name and the font size of the text information to be played, and accordingly control the text information to be played for display.
A text message playing method based on the text message playing apparatus will be described in detail below, which includes the following steps:
firstly, obtaining font attributes of character information to be played, such as font type, font name, font size and other attributes; in this embodiment, the font type may be a dot matrix font or a vector font.
And then, judging whether the font conversion is needed or not according to the font type of the character information to be played. It can be understood here that, since the first type font library is configured, if the font type of the text information to be played is a second type font different from the first type font, it is determined that font conversion is required, and certainly if the font type of the text information to be played is the first type font, font conversion is not required.
Then, when the font type of the text information to be played is a second type font different from the first type font, the font size of the text information to be played is scaled according to a preset proportion, then the matched first type font is searched from the first type font library 170 according to the font name of the text information to be played and the scaled font size, and the text information to be played is controlled to be played and displayed by the searched matched first type font, so that the effect similar to the display effect of directly playing and displaying the second type font according to the font attribute of the text information to be played is achieved. It can be understood that, if the font type of the text information to be played is the first type font, the matching font is found from the first type font library 170 directly according to the font name and the font size in the font attribute, and the playing and displaying are performed accordingly.
For ease of understanding, several examples of font conversion are specified below.
[ EXAMPLES one ]: when the font type, the font name and the font size in the font attribute of the text information to be played are respectively: lattice font, Song font and 64 x 64, and the configured font library is vector font library; therefore, in order to achieve the display effect required by the font property of the text information to be played, the dot matrix font size 64 × 64 is converted into the vector font size, and the converted vector font size is the font size of 48, namely (64 × 3/4); and then searching the Song font and the 48-Song font in the vector font library, and controlling the character information to be played and displayed in the vector font and the 48-Song font, wherein the displayed display effect is very close to the display effect of the character information to be played from the angle of human eyes, and the displayed display effect is directly played and displayed in a dot matrix font and a 64 multiplied by 64 Song font.
[ EXAMPLE two ]: when the font type, the font name and the font size in the font attribute of the text information to be played are respectively: vector font, Song font and No. 12 font, and the configured font library is a dot matrix font library; therefore, in order to achieve the display effect required by the font property of the text information to be played, the font with the vector font size of 12 is converted into the dot matrix font size, and the converted dot matrix font size is 16 × 16, namely (12 × 4/3) × (12 × 4/3); and then searching the Song font and the 16 x 16 font in the dot matrix font library, and controlling the character information to be played and displayed in the dot matrix font and the 16 x 16 Song font, wherein the displayed display effect is very close to that of the character information to be played from the angle of human eyes and is directly played and displayed in the vector font and the Song font with the number of 12.
In summary, the embodiment of the present invention only needs to set one type of font library to achieve the two types of font display effects, so that the font library of the system is simple to maintain.
