The present invention in building-up process, use mark tag in the Flash element to point to material database (Flash element database) thus in element revise tag, but not directly carry out the copy of element, so aggregate velocity is faster; Through parsing,, can realize synthesizing in order to Flash layered component (element) file then to recombinating between the internal data to (can be different Flash release formats) Flash file; And in building-up process, can accomplish parametrization adjustment, thereby the dynamic this locality that can realize user's virtual image is synthetic to size, position and the anglec of rotation of each layer assignment component object.
Description of drawings
Fig. 1 is the process flow diagram of the method for the embodiment of the invention.
Embodiment
For making the object of the invention, content and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
In design during synthetic method of the present invention, what consider is how correctly to resolve the Flash file and how the element among the different Flash is combined.
To correctly resolve the Flash file, just at first know the file structure (can learn) of Flash from the Flash file structure instructions (flash_fileformat_specification) of official.The Flash file is a kind of file structure based on the position compression; That is to say that unit is position rather than byte in the Flash file; Sometimes a byte possibly stored several information; Sometimes an information is striden byte, and back several the former positions that add next byte of promptly going up a byte are only a complete information.
In the Flash file, basic dtd is following:
The variable of integer type all is to represent that with the computer byte order of representation of little-endian promptly low byte is placed on the front, and high byte is put behind.
Integer type is divided into following several kinds: unsigned int; The symbol integer is arranged; (fixed-point number generally is used for supporting not have the Flash on the floating-point operation equipment fixed-point number.Simulate floating point arithmetic (in the PC performance history, generally need not use this data type) with fixed-point number); Floating number; Bit Value (bit data).In Flash, also have some senior data types, but all be to constitute similar with basic data type.
The form of Flash file is to be made up of file header and file body in general.Following table 1 provides the file structure based on the Flash of Flash8.0:
| File header |
| Attribute list |
| Element tag |
| Element tag |
| ... |
| EndTag |
Table 1
Wherein, whether file header has identified the version of this Flash file and has been compressed; Attribute list has defined information such as the size, background colour of this Flash file; Element tag refers to form the various component identifications in this Flash file, such as ShapeDefineTag, ObjectTag etc.; EndTag is an EOF, also represents all elements tag definition so far to finish simultaneously.
Wherein, element tag just has at Flash8.0 and above version.
After having understood these structures, just can resolve to each Flash element with reference to disclosed Flash document protocol.Resolve to accomplish and just can carry out synthetic operation afterwards.
Synthetic is exactly to generate a new Flash file in fact, also must observe above-mentioned Flash file layout for newly-generated Flash file.
As shown in Figure 1, the Flash synthetic method step of the embodiment of the invention is following:
S0, obtain the synthetic description document of XML, described order, quantity, title and the attribute of synthetic resource in this document.For example:
<fashion?style＝″1″sex＝″0″bg＝″0″>
<item?x＝″0″y＝″0″scale＝″1″res＝″pants_0.swf″/>
<item?x＝″0″y＝″0″scale＝″1″res＝″coat_0.swf″/>
<item?x＝″0″y＝″0″scale＝″1″res＝″face_0.swf″/>
<item?x＝″0″y＝″0″scale＝″1″res＝″hair_0.swf″hasBack＝″hairback_0.swf″/>
</fashion>
The synthetic description document of top XML has been described the synthetic situation of an elemental user virtual image (such as a QQ show), i.e. Flash positions of elements, convergent-divergent rate and title.
S1, according to the synthetic description document of XML with each synthetic resource downloading to local, if this locality has resource just no longer to download.All resource downloading up to appointment finish.
S2, resolve, elements all among the Flash is all parsed according to the numbering and the structure of Flash file structure and mark (tag).And find corresponding tag according to the description in the synthetic description document of XML; And the attribute of change tag; In general; The attribute of mark in the PLACE_OBJECT flag sequence in the Flash file structure (PLACE_OBJECT, PLACE_OBJEC_2, PLACE_OBJECT_3) is used for information such as control position, zoom ratio; As long as it is parsed and revise corresponding property, for example according to the definition in the XML file, the parametrization of size, position and the anglec of rotation of carrying out to each assembly unit parts (Flash file) is adjusted.
S3, all resource file parsings finish and have revised after the respective attributes and just can organize new file; Get final product according to the reorganization of Flash file structure; Here be noted that; Each tag in the Flash file all has numbering, and the tag information that comes from the different resource file might be numbered repetition, therefore; When setting up new Flash file, to all tag sequence numbers be arranged again, will notice during arrangement that other tag sequence numbers to its control also will be done modify among the PLACE_OBJECT.So far, composite document is accomplished.
Can find out that by above embodiment the present invention is through resolving the Flash file and revise the tag attribute and realize that Flash is synthetic, and can realize effects such as various displacements, convergent-divergent through revising the tag attribute.This scheme is more flexible in realizing synthetic process, has also alleviated the workload of art worker when related resource is provided simultaneously greatly.When program design, adopted new program structure, the various material objects in each Flash file have been carried out arranging again, and used unified material (Flash element) storehouse, with the storage material.In building-up process, use material sign (tag) to point to material but not direct object copy in the material database, aggregate velocity is faster.
Above embodiment only is used to explain the present invention; And be not limitation of the present invention; The those of ordinary skill in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also be made various variations and modification; Therefore all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
