Embodiment
Embodiment
Below be conjunction with figs., describe the embodiment of e-file display processing method of the present invention and system in detail.
Fig. 1 is the basic structure of the Object Oriented OO component model (object-oriented component model) of e-file display processing system of the present invention (part that comprises as the frame of broken lines of label 100 indications).As shown in the figure, in practical application, e-file display processing system 100 of the present invention carries to computerized information platform 10, the computerized information platform under the (SuSE) Linux OS for example, character string to a kind of e-file 20 of specific format, the character string of the e-file 20 of PDF (PortableDocument Format) form for example, carry out the display process of an ad hoc fashion, whereby with the content of this e-file, comprise literal, picture, form etc., by a kind of specific window, for example the QT window is shown on the computer screen 11 of computerized information platform 10; It can eliminate the blank parts in the shown file content, makes the file content that shows have composing effect more attractive in appearance.
The Object Oriented OO component model of e-file display processing system 100 of the present invention comprises at least: (a) read module 110; (b) display window is set up module 120; (c) dot matrix figure sets up module 130; (d) data object is described module 140; (e) blank cancellation module 150; And (f) display control module 160.
Read module 110 is in order to read the character string of PDF e-file 20, to obtain all data objects (for example literal, figure, form etc.) in this PDF e-file 20, and the relevant display properties of these data objects, comprise text formatting (font, pattern, size, color etc.), graphic presentation attribute, form display properties etc.
Display window is set up module 120 can set up display window in the QT window, show the content of this PDF e-file 20 by this display window.It is to utilize that this display window is set up module 120, for example the XcreateGC among the Xlib of X Window sets up, and with wherein each graph window display properties, comprise foreground, background colour, live width etc., be stored in drawing environment (GraphicContext, GC) in.
Dot matrix figure sets up module 130 and can be used to set up dot matrix Figure 131, utilizes this dot matrix Figure 131 to depict the content of this PDF e-file 20, comprises literal, figure, form etc.It is to utilize that this dot matrix figure sets up module 130, and for example the XcreatePixmap among the Xlib sets up.
Data object is described module 140 can read above-mentioned read module 110 from this PDF e-file 20 each data object, comprise lteral data object, graphic data object, list data object etc., according to the predetermined display properties of each data object, describe to set up on dot matrix Figure 131 that module 130 set up to above-mentioned dot matrix figure in the dot matrix mode.If data object is described module 140 and find some data objects in being described process, example literal data object 30 as shown in Figure 3A, when in framework 132, showing, and there is blank parts 31 between the side of framework 132, then can sends a blank active information of eliminating to blank cancellation module 150.
Blank cancellation module 150 can respond above-mentioned data object and describe blank that module 140 sends and eliminate active information and carry out blank elimination program, and the blank parts 31 of the side of this literal data object 30 is eliminated.The basic conception of this blank elimination program is, with position, the upper left corner (TX of literal data object 30
1, TY
1) and position, the lower right corner (TX
2, TY
2) overlapping upper left corner coordinate (X to its display frame 132
1, Y
1) and lower right corner coordinate (X
2, Y
2), its operational method is as shown in Figure 2.Eliminate after the blank, blank cancellation module 150 promptly can make data object describe the data object 30 that module 140 will eliminate after the blank and describe to dot matrix Figure 131.Fig. 3 B is the example that again literal data object 30 is shown in after blank parts shown among Fig. 3 A 31 is eliminated in the framework 132.
Display control module 160 can be described above-mentioned data object literal that module 140 describes in the dot matrix mode, figure, form etc. on this dot matrix Figure 131, be shown in by the QT window on the screen 11 of this computerized information platform 10.
When practical operation, e-file display processing system 100 of the present invention, at first make read module 110 read the character string of PDF e-file 20, obtain all data objects (for example comprising literal, figure, form etc.) in this PDF e-file 20, and the relevant display properties of these data objects, comprise text formatting (font, pattern, size, color etc.), graphic presentation attribute, form display properties etc.; And activate display window simultaneously and set up module 120, in the QT window, set up display window, (Graphic Context GC), sets up display window to the drawing environment that utilization is just built in advance in the QT window; Set up module 130 by dot matrix figure again and set up dot matrix Figure 131.
Then, make data object describe module 140 reads above-mentioned read module 110 from this PDF e-file 20 each data object,, describe to dot matrix Figure 131 in the dot matrix mode according to the relevant display properties of each data object.If data object is described module 140 and find some data objects in being described process, for example the literal data object 30, when there is blank parts 31 in side, even blank cancellation module 150 is carried out flow process shown in Figure 2, eliminate the blank parts 31 of these data object 30 sides, then make data object describe module 140 again and will eliminate the content of the data object 30 after the blank and describe to dot matrix Figure 131.Make display control module 160 that above-mentioned data object is described literal that module 140 describes in the dot matrix mode, figure, form etc. at last on this dot matrix Figure 131, be presented at by the QT window on the screen 11 of this computerized information platform 10.
In a word, the invention provides a kind of e-file display processing method and system of novelty, it can carry to information platform, in order to the character string of the e-file of specific format is carried out the display process of ad hoc fashion, the content with this e-file is shown on the computer screen by a kind of specific window whereby; Its characteristics are, can eliminate the blank parts in the shown file content, make the file content that shows have composing effect more attractive in appearance.Therefore the present invention has better progressive and practicality than prior art.
