Abstract

The invention provides a method for flexibly storing and displaying icons. According to the memory mode of a text word stock of embedded equipment, the icons are stored in the text word stock and are encoded, and text codes are directly mixed with icon codes to form a character string; if text and icon display needs to be corrected in a later period, the corresponding character string in a resource document can be directly corrected, and program codes do not need to be corrected; the combined character string can be displayed through the direct invocation of a text API (Application Programming Interface) function in a corresponding program position. The purpose of correcting a text and icon display mode without altering program can be achieved, so that the icons are flexibly displayed, and storage space can be reduced.

Description

A kind of method of flexible storage and display icon

Technical field

The present invention relates to a kind of character library flexible storage of embedded device and method of display icon utilized.

Background technology

Embedded device often need to show some simple icons, usually can be combined and show with word.Current common way is, first icon made to picture format, be stored in embedded device, and when needs show, first display icon, then display text.Program needs first to call picture API(interface function on realizing) icon of storage is shown, then calling word API shows word.Because the interface demand of various products is not quite similar, the binding sequence of icon and word also can be different because of needs, if the adjustment that put in order of icon and word, just need to remodify program, these are adjusted at the development phase and will often occur, and this has increased the workload of exploitation undoubtedly greatly.In addition, the storage space that need to take due to storage picture is larger than general word, if need the icon of demonstration many, needs more jumbo storer, thereby has increased the cost of embedded device.

Summary of the invention

The object of the present invention is to provide a kind of method of flexible storage and display icon, both can accomplish do not changing under the prerequisite of program, word and icon display mode are modified, thereby display icon neatly can reduce storage space again.

A method for flexible storage and display icon, step specific as follows:

Step 1, according to the storage mode of embedded device word character library, icon is stored in word character library and to its coding, this coding adopts present encoding to concentrate undefined code value;

Step 2, word and icon are combined: meeting under the prerequisite of concrete programming grammar, directly the coding of word and the icon formation character string that mixes; On the resource file that the character string program of being stored in can be accessed, and specify an identifier, make program find this character string by this identifier; If the later stage need to be revised the demonstration of word and icon, directly revise character string corresponding in resource file, do not need update routine code;

Step 3, at the corresponding place of program direct calling word api interface function, just can demonstrate the character string after combination.

Described step 1 specifically comprises the steps:

(1) with Window drawing tools, open after the icon that needs to show, calculate the pixel value of this icon;

(2) by character library handling implement, open the font file of program, select the position of an encoded radio not being used to set up a blank word, the pixel value identical with the icon that needs to show is set;

(3) icon showing as required, manually depicts figure at this blank word location, after operation character library handling implement converts this figure to .C code file, exports new font file, original font file in replacement program.

Adopt after technical scheme of the present invention, can have the following advantages:

1, the present invention at display text when icon is combined, can be directly word and icon according to the direct synthetic new character string of demand, during routine call word API, directly this, word and the icon after combination shows, the combination of display text and icon neatly;

2, icon of the present invention is stored in character library in an identical manner with word, and the form storage with respect to picture, can reduce storage space, thereby has reduced the cost that embedded device drops into;

3, the present invention due to by picture-storage in character library, amending method is the same with word, with respect to traditional complicated picture amending method, simple and convenient, the order adjustment showing for word and icon, can, without update routine, reduce development amount.

Accompanying drawing explanation

Fig. 1 to Fig. 4 is that in the present invention, icon stores step schematic diagram in common language character library into;

Below in conjunction with the drawings and specific embodiments, the invention will be further described.

Embodiment

The method of a kind of flexible storage of the present invention and display icon, comprises the steps:

Step 1, according to the storage mode of embedded device word character library, icon is stored in word character library and to its coding, this coding adopts present encoding to concentrate undefined code value, the most of latticed form that adopts of described embedded device Chinese word character library is stored, by the form of crossover tool or manual described point, just icon can be stored in word character library, specifically comprise the steps:

(1) obtain the icon that need to show as shown in Figure 1, after opening with Window drawing tools, can see the pixel distribution of icon as shown in Figure 2, from figure, can calculate, this icon as numerical values recited, be 11*12;

(2) by character library handling implement, open the font file of program, a blank word is set up in the position of selecting an encoded radio not being used for example 0XFFF1, and it is 11*12 that icon pixel value size is set, as shown in Figure 3;

(3) icon showing as required, manually depicts figure as shown in Figure 4 at this blank word location, after operation character library handling implement converts this figure to .C code file, exports new font file, original font file in replacement program.

The character set encoding that the present embodiment is used adopts UNICODE, also can adopt other coding; This character library handling implement mainly completes the conversion from generating writing pattern to .C code, also can manual modification .C code; The form of font file is .C code file not necessarily, other file layout that as required also can generator program can read.

Step 2, word and icon are combined, specifically comprise the steps:

(1) meeting under the prerequisite of concrete programming grammar, directly the coding of word and the icon formation character string that mixes;

(2) on the resource file that the character string program of being stored in can be accessed, and specify an identifier, make program find this character string by this identifier;

(3) if the later stage need to be revised the demonstration of word and icon, directly revise character string corresponding in resource file, do not need update routine code;

Object lesson is as follows:

In exploitation in earlier stage, certain interface needs to show:

this is a VPN icon;

According to C/C++ grammer, can be write as like this: " xfff1 This is a VPN icon ", wherein " xfff1 " is exactly the coding of VPN icon, stores resource file String.xml into upper, and distributes an identifier String_VPN;

If arrived development late stage, this interface need to be revised and be shown below:

The?VPN?iconis?

Directly the character string that in resource file String.xml, String_VPN is corresponding is modified as: " The VPN icon is xfff1 ", does not need update routine code.

Step 3, at the corresponding place of program direct calling word api interface function, just can demonstrate the character string after combination.For example DrawText () is a word API, and program is directly called DrawText (String_VPN), just can show the character string after combination, as follows:

This?is?a?VPN?icon。

The above, it is only preferred embodiment of the present invention, not technical scope of the present invention is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment all still belong in the scope of technical solution of the present invention.
