Embodiment
The present invention carries out literal or picture that needs can arbitrarily be changed to convert bitmap to after the editing and processing, and conversion generates dot matrix according to message bit pattern again.
As shown in Figure 1, present embodiment may further comprise the steps:
Step S110: selection need be made the literal or the picture of dot matrix.Such as, from ISO/IEC 8859 character set of the ISO (International Standards Organization) of corresponding language, select to make the literal of dot matrix.
Step S120: the literal or the picture that use the picture handling implement that needs are made dot matrix carry out editing and processing, save as the picture file of bitmap format.
The picture handling implement has a lot, such as softwares such as photoshop, coredraw.With photoshop software is example: creating size and background identical with literal or picture number of pixels in photoshop is transparent graphic template; Character among the step S110 or picture reproduction to the graphic template of creating, are adjusted the font of character or picture or size etc. according to actual needs, the picture that obtains is saved as the picture file of the BMP form of 8 position index looks.
Step S130: because the information of each pixel is stored respectively in the picture file of bitmap format, therefore, can extract message bit pattern from picture file easily, that is to say the pixel value of each pixel in the picture that extracts the BMP form.
Step S140: set up the array that a data element number equals number of pixels, with corresponding data element in this array of pixel value assignment of each pixel.Such as, the size of BMP picture is the M*N pixel, then newly-built array D[M] [N], and D
I, jThe value of [i] [j] is that sequence number is (I, pixel pixel value j) (wherein, 1≤i≤M, the integer of 1≤j≤M).
Step S150: with corresponding 1 bit of each data element (bit) position, the value that makes data element is that the bit of 0 o'clock correspondence is 0, and the value of data element is not that the bit of 0 o'clock correspondence is 1 to control the generation dot matrix.
Because when generating dot matrix, whether computing machine is only paid close attention to each dot matrix and is shown.Such as word lattice, have only the pixel of literal writing process, the pixel value of its pixel is not 0, needs to show when generating dot matrix; And the literal writing without pixel, the pixel value of its pixel is 0, does not need when generating dot matrix to show.Therefore, for array D[M] numerical value of each data element in [N], have only whether the value of being concerned about each data element is 0X00, as be 0X00, then Dui Ying bit is 0; As the data element is not 0X00, and then Dui Ying bit is 1.
For example, for 8 pixels for the array D:0x00 that constitutes by 8 data elements; 0x01; 0x02; 0x03; 0x04; 0x05; 0x06; 0x00 is if the data element in each pixel or each array represents as LED-lattice Control with 1bit that respectively then can use binary number: 01111110 (being 0x7e) represented.Therefore, for array D[M] [N], need M*N bit to control the generation dot matrix equally.
In conjunction with shown in Figure 2.The device of disclosed generation literal of present embodiment or graphic dot matrix, it comprises: editing and processing unit 10, bitmap extraction unit 11 and dot matrix generate control module 12.Literal or picture that described editing and processing unit 10 is used to use the picture handling implement that needs are made dot matrix carry out editing and processing, save as the picture file of bitmap format; Described bitmap extraction unit 11 is used for extracting message bit pattern from described picture file, obtains the pixel value of each pixel; Described dot matrix generates control module 12 and is used for respectively with corresponding 1 pixel of 1 bit, and making pixel value is that the bit of 0 pixel correspondence is 0, and pixel value is not that the bit of 0 pixel correspondence is 1, uses the bit identical with number of pixels to control the generation dot matrix.
Wherein, described dot matrix generation control module 12 comprises: array generates and processing module 121 and LED-lattice Control module 122.Described array generates with processing module 121 and is used to generate the array that a data element number equals number of pixels, gives corresponding data element in this array with the value difference assignment of each pixel; Described LED-lattice Control module 122 is used for corresponding 1 bit of each data element, and the value that makes data element is that the bit of 0 o'clock correspondence is 0, and the value of data element is not that the bit of 0 o'clock correspondence is 1 to control the generation dot matrix.
To sum up, the present invention carries out editing and processing with using the picture handling implement by the literal that will need arbitrarily to change or picture, saves as the picture file of bitmap format; Then, because the information of each pixel is stored respectively in the picture file of bitmap format, therefore, can extract message bit pattern from picture file easily; Whether the pixel value of judging each pixel again is 0, and the control pixel value is that 0 pixel does not show in dot matrix, and pixel value not to be 0 pixel show in dot matrix gets final product.
Therefore, the present invention converts the dot matrix demonstration to by the literal or the picture that will need arbitrarily to change, literal or picture that dot matrix is shown can arbitrarily be changed according to user's needs, thereby make the interface prompt language of electronic product arbitrarily change font style and font size, improve the hommization of electronic product according to client's needs.
