Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
The process flow diagram of the file layout change-over method that provides for preferred embodiment according to the present invention shown in Figure 1;
The synoptic diagram of the file layout conversion equipment that provides for preferred embodiment according to the present invention shown in Figure 2.
Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
The process flow diagram of the file layout change-over method that provides for preferred embodiment according to the present invention shown in Figure 1 may further comprise the steps:
Step 101: last non-NULL row of each page of pending file are carried out the self-adaptation adjustment, obtain each picture maximum height and breadth extreme in adjustment each page maximum height of back and breadth extreme, the page.
At first; Each page of pending file is adjusted; Particularly, travel through each row of the pending file page, obtain the col width L1 of last non-NULL column unit lattice; Col width to last non-NULL column unit lattice carries out the self-adaptation adjustment, obtains the adjusted col width L2 of said last non-NULL column unit lattice.
Secondly, obtain each picture maximum height and breadth extreme in adjustment each page maximum height of back and breadth extreme, the page.The maximum height of obtaining each picture in the page of adjustment back with the process of breadth extreme is: travel through line by line and search picture, obtain height, the width of each picture successively and compare, obtain higher value, obtain the maximum height and the breadth extreme of picture.For example, the height that the height that obtains first pictures is 9, width is 4, the second pictures is 8, and width is 6; Then give maximum height with numerical value 9 assignment, numerical value 6 assignment are given breadth extreme, next search the 3rd pictures; With the height and numerical value 9 comparisons of the 3rd pictures, the higher value assignment is given maximum height, with the width and numerical value 6 comparisons of the 3rd pictures; The higher value assignment is given breadth extreme, by that analogy, searches the picture end up to traveling through line by line.
Step 102: compare page maximum height and said picture maximum height, get higher value as page height H, relatively page breadth extreme and said picture breadth extreme are got higher value as pagewidth W.
Step 103: obtain paper height H 1 and paper width W 1.Said paper height and paper width are meant content of pages is printed on the paper height of said paper and width.
Step 104: obtain the ratio of H1 and H and the ratio of W1 and W, give M with the smaller value assignment, if M＜1, then the scaling with the said M of each page foundation of adjusted file carries out convergent-divergent output.
As stated, if then directly export said adjustment back each page of file M >=1.
With the process of adjusted each page output be: at first each conversion of page of adjusted file is become PDF, convert picture format to by PDF again, output on the webpage at last, or print to paper.
For example, adjusted pending file comprises the page one and the page two, value after relatively page-out one page face height be 40 centimetres, pagewidth is 30 centimetres.Obtaining the paper height is 36 centimetres, and the paper width is 24 centimetres.This moment, the ratio of H1 and H was 36: 40=0.9, the ratio of W1 and W are 24: 30=0.8, then give M with smaller value 0.8 assignment; This moment, M＜1 was carried out convergent-divergent output with the page one according to the scaling of M=0.8, promptly; The said page one page height multiply by 0.8 by 40 centimetres be scaled 32 centimetres; Pagewidth multiply by 0.8 by 30 centimetres and is scaled 24 centimetres, and outputing to highly is 36 centimetres, and width is on 24 centimetres the paper.
And for example, value after relatively page-out two page heights be 30 centimetres, pagewidth is 24 centimetres.Obtaining the paper height is 36 centimetres, and the paper width is 24 centimetres.This moment, the ratio of H1 and H was 36: 30=1.2; The ratio of W1 and W is 24: 24=1, give M with smaller value 1 assignment, at this moment M >=1; Then said adjustment back each page of file is directly exported; That is, it highly is 36 centimetres that the said page two is directly outputed to according to life size, and width is on 24 centimetres the paper.
The synoptic diagram of the file layout conversion equipment that provides for preferred embodiment according to the present invention shown in Figure 2.As shown in Figure 2, the file layout conversion equipment 1 that preferred embodiment of the present invention provides comprises adjusting module 10, value module 20, acquisition module 30 and processing module 40.Wherein, adjusting module 10 connects value module 20, and value module 20 connects acquisition module 30, acquisition module 30 connection processing modules 40.Adjusting module 10 is used for last non-NULL row of each page of pending file are carried out the self-adaptation adjustment, obtains each picture maximum height and breadth extreme in adjustment each page maximum height of back and breadth extreme, the page.Value module 20 is used for comparison page maximum height and picture maximum height, gets higher value as page height H, and relatively page breadth extreme and picture breadth extreme are got higher value as pagewidth W.Acquisition module 30 is used to obtain paper height H 1 and paper width W 1.Processing module 40 is used to obtain the ratio of H1 and H and the ratio of W1 and W, gives M with the smaller value assignment, if M＜1, then the scaling with the said M of each page foundation of adjusted file carries out convergent-divergent output.
In sum; File conversion form method and device that preferred embodiment according to the present invention provides output on the webpage converting picture format to after the automatic adjustment of diagram file, have kept the integrality of file; And need not download other office software, can on webpage, directly read.The present invention is applicable to the excel part of microsoft office, also is applicable to the excel part among the WPS.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
