Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
As shown in Figure 1, be the schematic flow sheet of a kind of text message transfer approach of the present invention, comprise the steps:
S11, obtain the binaryzation lattice information of word, described lattice information is converted to bitmap;
According to the word of user's input, extract type matrix according to word content, font type, font size, extract the lattice information of binaryzation from dot matrix word library;
Dot matrix word library is a data file, has preserved the dot array data of all words in this data file the inside, and dot matrix is exactly monochrome bitmap in essence, it means a point with a bit, if bit is 0, mean that certain position does not have a little, 1 means certain position a little if; As shown in Figure 2, be the lattice information schematic diagram of Chinese character in the present embodiment " good "; Wherein the dot matrix font can directly be extracted, and vector fonts extracts after need first putting array again;
Generate data bitmap according to lattice information, data bitmap is the same with lattice information, by a plurality of pixels, formed, equally can be as shown in Figure 2, each pixel storage pixel value, the bitmap generated according to the lattice information of binaryzation, comprised a plurality of pixels, the numerical value of pixel only has two kinds of situations, can be 0 or 1, and have a plurality of continuous identical pixels of pixel value, be conducive to follow-up compression coding.
S12, according to the pixel value of pixel in default minimum code unit and described bitmap, determine all encoded block, and described encoded block be numbered;
In a preferred embodiment, the default minimum code unit of described basis determines that from described bitmap the step of all encoded block is:
Determine 2 according to described default minimum code unit
nMplant the encoded block of storage different pixel values, wherein, described default minimum code unit is the rectangle that N*M pixel forms, and described N is more than or equal to 1 integer, and described M is more than or equal to 1 integer; In described bitmap, the pixel value of each pixel is 0 or 1;
S13, by default coded sequence and minimum code unit, read described bitmap, read each time current encoded block from encoded block when different, record the read-around ratio of an encoded block;
As shown in Figure 2, comprise a plurality of continuous identical pixels of pixel value in bitmap; If take each pixel as minimum code unit, whole 32 of the first row is all 0, so direct representation is (32,0), back to back 4 row full 0s can be with same method representation, and the 6th row can be expressed as (9,0), (2,1), (21,0).Due to the characteristic of word, there will be a large amount of continuous 0 or continuous 1 in data bitmap, so use said method can greatly improve ratio of compression; Wherein, the present embodiment reads bitmap with the behavior coded sequence, also can read bitmap to classify order as according to actual needs, or sequentially be read with Multi-encodings such as Z-shaped coded sequences.
Characteristics according to bitmap, owing to having continuous 0 or continuous 1, and in the horizontal direction with on vertical direction, be exist associated, in order to consider the relevance on horizontal direction and vertical direction simultaneously, in fact larger minimum code unit can be set, to accelerate coding rate and to improve ratio of compression;

Above-described embodiment be take a Chinese character and has been set forth cataloged procedure as example, can be also multiple bitmaps by the word corresponding conversion of all inputs, is encoded after splicing all bitmaps again; Perhaps after the splicing of the bitmap of a plurality of words, encode again, specifically can be decided according to the actual requirements.
S14, will the numbering of the length and width of described bitmap, coded sequence, minimum code unit, encoded block and the read-around ratio packing after output;
In a preferred embodiment, the numbering of encoded block and read-around ratio thereof can be stored in a byte as one group, described numbering is stored in the high N*M position of each byte, described read-around ratio is stored in low 8-N*M position, wherein, N*M is less than 8, and described N is more than or equal to 1 integer, and described M is more than or equal to 1 integer; Described default minimum code unit is the rectangle that N*M pixel forms, can there be the multiple choices mode in minimum code unit, as 2*2,2*3,4*4 etc., in the present embodiment, be preferably N*M and be less than 8, prevent that corresponding encoded block number is too much on the one hand, weaken compression speed, also be convenient on the other hand be stored in a byte using the numbering of encoded block and read-around ratio thereof as one group, facilitate the Graphics Processing of data packing storage and receiving end.
Wherein, also can add sign, for recording and identify above-mentioned coded format, for example, front four bytes are 0x54, 0x58, 0x54, 0x50, sign as this coded format, follow four length that byte is bitmap, follow again four width that byte is bitmap, then a byte is coded sequence again, 0 means with the behavior order, 1 means to classify as order, then a byte is minimum code unit again, preserve N for high 4, preserve described M for low 4, the total length that then four bytes are data bitmap after subsequent compression again, be finally the data after compression, packed data be take each byte as one group, the numbering of the encoded block in Fig. 3 is preserved in the high N*M position of this byte, the read-around ratio of low 8-N*M bit representation encoded block.
As shown in Figure 4, be the schematic flow sheet of a kind of text message display packing of the present invention, comprise the steps:
The text message compressed package of S41, reception input, wherein, the numbering of the length and width that described compressed package comprises bitmap, coded sequence, minimum code unit, encoded block and read-around ratio thereof;
S42, according to the length and width of described bitmap, generate described bitmap, according to described coded sequence and minimum code unit, according to numbering and the read-around ratio thereof of encoded block, the default encoded block corresponding with described numbering is filled in described bitmap.
