Description
The present invention relates to a kind of character displaying method, particularly relate to a kind of Chinese character display method that is used under the computer viewing window environment.
Under traditional English windowing environment, for example be used in the MicrosoftWindows on the IBM personal computer, can't show Chinese character; Therefore, if use the relevant software of Chinese, must (Chinese Windows) ability regular event and demonstration under the windowing environment of Chinese.Press, shown font can be divided into three kinds of raster font (raster), vector fonts and truetype fonts (Truetype) under the Chinese and English windowing environment.Wherein raster font is that form with figure stores, and vector fonts is that (graphic device interface GDI) stores font to the utilization graphical device interface, and truetype fonts then is that the mode via the Points And lines set of determining character outline stores.Show that for above-mentioned font the Windows form provides User, Kernel and three kinds of functions of GDI; In User and GDI function library, some character explicit functions are provided.For example, DrawText, ExtTextOut, TexOut etc. can come character display according to various forms, designated color, specific font or assigned address.
Because the Hanzi font library in the middle windows text is the truetype fonts form, so Chinese windowing environment has and takies storer and reach the slow shortcoming of display speed more greatly.
In view of above-mentioned traditional many shortcomings that display packing produced, fundamental purpose of the present invention is to provide a kind of and can be used under the Chinese and English windowing environment, shows the Chinese character display method of multiple font.
Another object of the present invention provides a kind ofly uses less storer and speed display packing faster than classic method.
According to above-described purpose, the invention provides a kind of Chinese character display method that is used under the computer viewing window environment.At first, the Chinese character of dot matrix is stored in the literal shelves, and produces dot matrix word library and index corresponding to dot matrix, wherein index is to arrange with the coded sequence of Chinese character.When using this display packing, first initialization dot matrix character library and index are to produce a monochrome bitmap and an Application Programming Interface (API) corresponding to dot matrix word library; Its step produces the monochrome bitmap corresponding to dot matrix word library again for reading in dot matrix word library and being indexed in the computing machine, to produce an Application Programming Interface (API) that is compatible to computer interface.Then, monochrome bitmap is selected in the Application Programming Interface (API), and according to the ISN of Chinese character, to produce the address of Chinese character in index, the sequence number of reading Chinese character again according to address.According to sequence number, read the dot matrix numerical value of Chinese character in dot matrix word library, and give monochrome bitmap dot matrix numerical value.At last, the monochrome bitmap in the computing machine is stored to Chinese character in the one target form, according to color settings achromatic sheet is converted to corresponding color, and Chinese character is shown on the display device of computing machine.When this self-built dot matrix word library and index when not required, then dot matrix word library, index, monochrome bitmap and Application Programming Interface (API) can be discharged.
Specifically, according to the present invention, a kind of method that shows as literal under the computer viewing window environment is provided, and this method comprises the following step: be initialized to an a little less battle array character library and an index, to produce a monochrome bitmap and an Application Programming Interface (API) corresponding to this dot matrix word library; This monochrome bitmap is selected in this Application Programming Interface (API); According to the ISN of a literal, to produce the address of this literal in this index; According to this address, read a sequence number of this literal; According to this sequence number, read the dot matrix numerical value of this literal in this dot matrix word library; Give this monochrome bitmap with this dot matrix numerical value; This monochrome bitmap in this computing machine is stored to this literal in the one target form; And, this literal is presented on the display device of this computing machine, wherein, described initialization step comprises the following step: read in this dot matrix word library and be indexed in this computing machine with this; Generation is corresponding to this monochrome bitmap of this dot matrix word library; And, produce this Application Programming Interface (API), wherein the interface of this Application Programming Interface (API) and this computing machine is compatible.
Figure 1A and Figure 1B represent detail flowchart of the present invention.
With reference to Figure 1A, be illustrated in the step of setting up character library before Chinese character shows in the frame of broken lines of number in the figure 10, it is with used different latticed forms, for example the Chinese character of 16*15 or 24*24 dot matrix is stored into literal shelves (text file) (step 101) respectively, and these literal shelves are handled by a software program, produce the dot matrix word library and the index of different latticed forms then in step 102 respectively, wherein index is to arrange with the coded sequence of Chinese character.In index, each Chinese character is corresponding fixed position; If this Chinese character has been used in the literal shelves, then the location number of this Chinese character in self-built character library deposited in this position; Yet if this Chinese character is not used, this position is made as zero.
Be illustrated in the preceding performed initialization step of real demonstration Chinese character among Figure 1A in the frame of broken lines of label 20.At first, storer (step 201) to the computing machine read in the dot matrix word library of corresponding dot matrix and index, and in monochrome bitmap (bit-map) structure (step 202) of the Chinese character of the upright corresponding dot matrix of memory built, simultaneously in step 203, at upright Application Programming Interface (API) (the application program interface compatible of memory built with Chinese character form to display, API, be called device context again), this Application Programming Interface (API) is the formula design language interface between General System control formula and user's formula.
In the time will showing Chinese character, at first corresponding dot matrix monochrome bitmap is selected into Application Programming Interface (API) (step 31), calculate the address of current Chinese character in index according to the encode Chinese characters for computer formula again, and according to this address to read the sequence number (step 32) of Chinese character.Then in step 33, read the dot matrix numerical value of Chinese character in dot matrix word library according to this sequence number.Give monochrome bitmap structure (step 34) with this dot matrix numerical value, again this monochrome bitmap is stored to the assigned address (step 35) in the target form.Then, transfer this monochrome bitmap to corresponding color (step 36) according to setting, and target window refreshed and Chinese character is presented at (step 37) on the display device.Show that Chinese character in display device, as the method on the terminating machine, is to use general display packing, and cooperate self-built function and some to call module to reach.For example, be shown under the windowing environment of IBM personal computer, can call out (call), use the listed function of table one.
