Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

As shown in fig. 1, the present invention provides a method for dynamically generating a font map, which is executed by a device for dynamically generating a font map, the device is implemented by software and/or hardware, and is specifically configured and equipped in an electronic device with mobile data computing capability, and the method specifically includes the following steps:

1. generating a blank initialization bitmap according to a preset size;

2. adjusting font parameters: font name, font size;

3. inputting and generating a fixed character set;

4. drawing all characters by using a font tool to generate a character paste picture set;

5. filling and drawing the character paste picture set in the initialization bitmap according to a certain sequence;

6. and generating and storing a character set mapping configuration file.

In this embodiment, a character mapping set is generated, and the characters in the fixed character set are split into pixel bitmaps in time for display, so as to implement dynamic rendering, as shown in fig. 2, "ABCD" is used as the fixed character set, and "a", "B", "C", "D" 4 mapping files with different sizes are generated, and in places where effects such as color, thickness, shadow, and edge tracing need to be added, the font files are rendered into image files to implement display of the text, so as to attract users well.

The final output file in this embodiment is composed of a configuration file of font maps and a bitmap file storing all character map sets, as shown in fig. 3, samples drawn into bitmaps are filled according to the character map set of fig. 2 and the final optimized positions, and "a", "B", "C", and "D" 4 map files are filled and merged into a fixed-size map file, and according to the design, each character is converted into a picture, sorted by size, and filled and stored in a fixed-size bitmap file after being corrected.

In the configuration file finally output in this embodiment, at least the character code corresponding to each character in the character set, the coordinate information and the size information of the character map in the bitmap are included, and each character occupies a row of the configuration file in sequence, for example: the profile corresponding to "char id ═ u534 e' x ═ 0 y ═ 0 width ═ 33 height ═ 36" shows that the chinese character "hua" corresponding to the Unicode code "\\ u534 e" is located at the (0, 0) coordinates, the size of the map is 33 pixels, and the width is 36 pixels.

In this embodiment, the character encoding of the character set may follow Unicode international encoding to support all languages including chinese, japanese, korean, english, and the like. Unicode is an industry standard in the field of computer science and includes character sets, coding schemes, and the like. Unicode is generated to solve the limitation of the traditional character encoding scheme, and sets a uniform and unique binary code for each character in each language so as to meet the requirements of cross-language and cross-platform text conversion and processing.

Example 2

As shown in fig. 4, the present invention provides a method for calculating the minimum bitmap size, which comprises the following steps:

1. sorting the character paste picture set;

2. adjusting the size of the output bitmap according to a preset sequence;

3. filling and putting all character paste picture sets to the bitmap size in sequence;

4. it is detected whether the size exceeds the maximum size.

In step 4, if the maximum size is exceeded, step 2 is repeated, using a one-step larger bitmap size.

In this embodiment, the unit of the bitmap size is a pixel, and the pre-specified size may be 128 × 128, 256 × 256, 256 × 128, 512 × 512, 1024 × 1024, 1024 × 2048, 2048 × 4096, 4096 × 4096, or the like according to the size of the display memory of the graphics card of the modern mobile hardware GPU.

In this embodiment, it is necessary to sort the character tile set, and for practical operation, different sorting strategies have very large effect differences under different character sizes, which is mainly reflected in that the width proportion of the final output bitmap is different. The policy of the ordering may be specified, and the policy may be selected to be: the area, width, height and the most lateral side of each character map are sequencing basis.

In this embodiment, each time a character map is placed, the bitmap is divided into a large space and a small space, and as shown in fig. 5, all the remaining character map sets that have been sorted need to be iteratively filled into the large space and the small space, so that the merging work of all the character map sets can be completed.

In this embodiment, it is necessary to merge all the character set maps into one bitmap. In practice, other fonts such as chinese contain a large number of characters, and if all character set maps are not merged, a large number of scattered maps will be generated, resulting in a reduction in the performance of mobile rendering.

Example 3

As shown in fig. 6, the present invention provides a dynamic generation apparatus for font maps, which specifically includes:

a character set input module: the system is used for generating character sets of languages including Chinese, Japanese, Korean, English and the like;

font chartlet design module: the character size of the font chartlet is set according to the font tool of the operating system, and the regulation and control parameters such as thickening, italics, drawing, shadow and the like are set;

a bitmap generation module: the method is used for outputting the font chartlet with the minimum size and the corresponding configuration file according to the size of the video memory of the modern mobile hardware GPU video card based on the input of the specified character set and the character chartlet set.

The font mapping drawing apparatus of this embodiment implements dynamic drawing of the font mapping by using the above modules, which is the same as the implementation principle of the above related method embodiment, and reference may be made to the description of the related method embodiment in detail, and details are not repeated here.

Example 4

As shown in fig. 7, the present invention provides a dynamic font chartlet generation apparatus, and the structural principle of the apparatus is further described in detail on the basis of fig. 6.

In the dynamic generation apparatus for font maps of this embodiment, the map preview module is specifically configured to display a real-time rendering effect of the font map in time according to the configuration file and the actual bitmap map.

In this embodiment, in actual operation, the map preview module generally displays 26 letters and 10 numbers 0-9, and does not display non-English letters such as Chinese, Japanese, Korean, etc. by default.

Optionally, the map preview module may detect whether the character set includes non-english letters such as chinese, japanese, korean, and the like, and when the detection is true, may intercept the first few characters input by the user for implementing the map preview. Because the character encoding of the character set is Unicode international encoding, the character sets of Chinese, Japanese, Korean and the like are in specific encoding bits in the Unicode encoding, and whether the character set contains non-English letters of Chinese, Japanese, Korean and the like or not can be detected according to the input Unicode encoding.

Further optionally, due to the addition of the map preview module, other configuration options can be added to the character configuration. In actual operation, the alpha value of the map edge is difficult to be accurately calculated due to the edge tracing and shadow effects, and can be corrected by adjusting configuration options such as the inner and outer margins of the character set, and the specific implementation configuration files include: "char id ═ u534 e' x ═ 0 y ═ 0 width ═ 33 height ═ 36 xoffset ═ 0 yoifset ═ 28", the corresponding profile indicates that the chinese character "hua" corresponding to Unicode code "\ u534 e" is located at the (0, 0) coordinate, the size of the map is 33 pixels, the width is 36 pixels, the x coordinate is offset by 0 pixels, and the y coordinate is offset by 28 pixels.
