Detailed Description
The present invention will be described in further detail with reference to the following embodiments:
a character library lattice generation method based on a generator set controller comprises the following steps:
step 1: determining the font and the size of a character library to be generated, wherein the size is the number of data bits occupied by the dot matrix of each character; for example, to generate 24 × 24 sized sons font, the number of dots required for each font is calculated, and 24 × 24 requires 576 dots, that is, 72 bytes; a total of 28672 characters in the Unicode code character set from 0x3000 to 0x9FFF, requiring 28672 x 72 bytes;
step 2: firstly, a Picture control is newly built, a Label is newly built on the Picture control, wherein the position of the Label is set to be (0, 0), the AutoSize attribute is set to be true, and the font size is set to be the font size in the step 1; then the word to be converted is displayed on a Label Label; putting a Label Label on a Picture, obtaining the RGB value of the (x, y) coordinate point by a Picture.Point (x, y) method, if the value is 0, indicating that the RGB value is a dot matrix on the word, calculating the size of a byte array according to the position of the byte, wherein V1 = V1 + 2 ^ (x), the lower bit is before and the higher bit is after;
and step 3: by a determinant scanning mode, scanning lines firstly, taking 8 points as a unit, scanning from left to right and from top to bottom, scanning low bits firstly and then scanning high bits, storing the 8 points as a byte into a byte array, scanning all character sets to obtain a dot matrix of the character, and then storing the dot matrix of the character into a dat file.
When the method is used, 0x3000 is subtracted from the Unicode code of the character to obtain the position of the character in the dat file, and then the dot matrix of the character is read out, so that the method can be directly used, and is convenient and quick.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
