Description

File processing method and related pattern display method

technical field

The present invention relates to a file processing method and a related pattern display method, in particular to a file processing method for processing files with dynamic components and static components and a related pattern display method.

Background technique

Generally speaking, many files such as PPT files, Flash files, World files, Excel files, and PDF files have static components and dynamic components. For example, the static component of a PPT file is its text, and the dynamic component is its effect when scrolling or special effect when it is displayed. These static components and dynamic components are all stored in the same file, and then processed by the same processing unit (such as the CPU of a computer, etc.). However, this kind of dynamic and static hybrid processing method will make the calculation more complex and slower.

In addition, the processing method of such files usually includes the function of enlarging (zoom in) or reducing (zoom out) the pattern, and the general practice is to reduce the original pattern to a certain size, and then adjust the pattern according to the desired pattern. Resize and display. However, such an approach has to be processed for each pixel, thus making the computation cost quite large.

Therefore, a new file processing method is needed to solve the above problems.

Contents of the invention

Therefore, an object of the present invention is to provide a file processing method to separately calculate and process the dynamic components and the static components in the file.

Another object of the present invention is to provide a pattern display method to provide a pattern display method with low computational complexity.

The embodiment of the present invention discloses a file processing method for processing files with dynamic components and static components, including: separating the files into dynamic files and static files, wherein the dynamic components of the file form a dynamic file, and the file’s The static component forms a static file; and performs processing operations on the dynamic file and the static file according to the file header, wherein the file header is located in one of the dynamic file and the static file.

Wherein the above-mentioned file is at least one selected from the group consisting of PowerPoint files, Flash files, Word files, Excel files, and PDF files. Alternatively, it can be a printable file.

The above-mentioned file header may include a static file index to indicate the location of the data of the static file, and the file header may further include a dynamic file index to indicate the location of the data of the dynamic file.

In addition, the file header may also include a thumbnail index to indicate the location of the thumbnail. However, in a preferred embodiment of the present invention, the thumbnail image is a part of the original pattern. And use the size of the thumbnail to cut the original pattern, and each adjacent cutting area has a repeated cutting part. Among them, the repeated cutting part is to make the original pattern be completely cut by the thumbnail without insufficient or redundant parts.

The embodiment of the present invention also discloses a pattern display method, including: using a predetermined size to cut the original pattern to form a plurality of thumbnails, and each adjacent cutting area has repeated cutting parts; and when a certain part of the original pattern is to be displayed , to display the thumbnail corresponding to the part to be displayed.

Through the above-mentioned processing method, the complexity of file processing can be greatly reduced, the amount of calculation when displaying thumbnails can be reduced, and the display of thumbnails can be more flexible, which proves that the present invention is nothing less than a novel invention.

Detailed ways

FIG. 1 is a schematic diagram of a preferred embodiment of the file processing method according to the present invention. As shown in FIG. 1 , a static file 100 includes a file header 101 , and the file header 101 includes a plurality of static file indexes 103 , 105 , 107 corresponding to static file data 109 , 111 , and 113 . When the static file data 109 , 111 and 113 are to be processed, the locations of the static file data 109 , 111 and 113 are first found out according to the static file indexes 103 , 105 , and 107 and then related processing is performed.

Moreover, as shown in Figure 2, the file header 101 also includes dynamic file indexes 201, 203 and 205, which correspond to the dynamic file data 207, 209 and 211 in the dynamic file 200 respectively, when the dynamic file data 207, 209 and 211, the location of the dynamic file data 207, 209, and 211 will be found out according to the dynamic file index 201, 203, and 205, and then related processing will be performed.

It should be noted that, in FIG. 1 and FIG. 2 , although the file header 101 is located in the static file 100 , it can also be located in the dynamic file 200 , and it does not depart from the scope of the present invention.

In addition, the file header 101 according to the present invention may further include a thumbnail index (not shown) to indicate the position of the relevant thumbnail. The thumbnail image is processed by the pattern display method of the present invention, which will be described in detail in FIG. 3 and FIG. 4 below.

的宽度，如此可使原始图案300完整的被缩图切割而不会有多余或不足的部分。FIG. 3 is a schematic diagram of a preferred embodiment of the pattern display method according to the present invention. As shown in FIG. 3 , the pattern display method according to the present invention is to use thumbnails 301 , 303 . Cut part 307 . The repeated cutting part is used to make the display of the thumbnail more flexible, that is, without the repeated cutting part, some parts of the original pattern 300 will be difficult to display, especially the middle part of the original pattern 300 . Moreover, when cutting at the beginning, there may be some cut parts that exceed the original pattern 300, such as the cut part 309 in FIG. 3 . At this time, the pattern display method according to the present invention adjusts the repeated cutting part 307 as shown in FIG. 4 so that the original pattern 300 can be completely cut by the thumbnail having a predetermined size. For example, if the repeated cutting portion 307 in FIG. 3 has a width M, the width of the cutting portion 309 is a, and the entire original pattern 300 has n repeated cutting portions, then the repeated cutting portion 307 in FIG. 4 will have

In this way, the original pattern 300 can be completely cut by the thumbnail without redundant or insufficient parts.

It should be noted that although FIG. 3 and FIG. 4 only use one side of the original pattern for illustration, the other side can also be handled in the same way, and it does not depart from the scope of the present invention.

Through the above-mentioned processing method, the complexity of file processing can be greatly reduced, the amount of calculation when displaying thumbnails can be reduced, and the display of thumbnails can be more flexible, which proves that the present invention is nothing less than a novel invention.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
