In order to realize technical scheme of the present invention, need technical solution problem:
1, identify for the overall region in multizone form.
2, the region identifying is carried out the drafting of picture, and picture is optimized to processing.
The first problem solving for the needs of above-mentioned proposition: for the overall district in multizone formRow location, the present invention has designed zone location device 300 as shown in Figure 3.
As shown in Figure 3, zone location device 300 is mainly used in locating the size of multizone, realize manyThe location in region mainly contains 3 parts:
Region identifier 302: this identifier is mainly used in identifying the type in the various regions in form.The step of identification is as follows:
1. each cell of traversal, checks whether the extended attribute in each cell has picture categoryType and form types.
If 2. have picture or form types, in declare area, there is picture or form types, and oneIn the extended attribute of individual cell, only may there is the one in picture or form types, or not have.
If 3. there is no picture and form types in the extended attribute of cell, check in cell and whether haveValue. If there is value, this region memory is at literal type.
Region calculator 304: respectively each region is calculated according to the area type identifying.The step of calculating is as follows:
1. are the minimum rectangle scopes that obtain holding this region for each region.
2. the rectangular area of 3 types is superposeed and obtains holding these 3 kinds of rectangular areas simultaneouslyMinimum rectangle scope.
3. the large region obtaining is the region of corresponding whole form.
Optimization of region device 306: need to carry out certain optimizing and revising to the form region obtaining. OptimizeProcess be to obtain on the basis in form region the space that respectively has more up and down 10 pixels,Make like this thumbnail that obtains can be too compact. Certainly, also can determine whether according to actual conditionsNeed mobile or mobile concrete pixel value.

Obtain through the processing of graphic process unit 500 thumbnail generating again, can utilize figure herePicture size processor 502 in processor 500 is set the picture size obtaining, and (picture is squareShape, sets its length and wide), and utilize the picture pattern processor 504 in graphic process unit 500Picture is carried out to sharpening and gray scale operation is set etc.
Undistorted after amendment for ensureing picture size, can use bilinearity to increase progressively convergent-divergent skill hereArt.
Fig. 6 shows the flow chart for report generation thumbnail according to an embodiment of the invention.
As shown in Figure 6, according to an embodiment of the invention for the flow process of report generation thumbnail comprises:
Step 602, obtains report data.
Step 604, carries out region identification to report data, thereby obtains area type.
Step 606, carries out region calculating to report data, thus the regional extent of obtaining.
Step 608, carries out optimization of region to report data, thereby obtains drawable regional extent.
Step 610, carries out graphic plotting to report data, thereby obtains drawing successful Drawing Object
Step 612, carries out graphics process to report data, thereby sets size, the ash of thumbnailThe attributes such as degree.
Step 614, the picture that output is finished dealing with.
Step 616, by picture-storage to server.
More than be described with reference to the accompanying drawings technical scheme of the present invention, by technical side of the present inventionCase, has effectively solved multizone form and cannot normally generate the problem of thumbnail, and can controlGenerate the size of thumbnail, and ensure that picture is undistorted.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, forThose skilled in the art, the present invention can have various modifications and variations. All in essence of the present inventionWithin god and principle, any amendment of doing, be equal to replacement, improvement etc., all should be included in the present inventionProtection domain within.
