In order to help that the more employed notions of the inventive method are described, below will do a concise and to the point explanation of nouns:
(1) white space: shown in Figure 1, it is the synoptic diagram in the inventive method empty zone.In the format setting process, wait until the rectangular area of filling, use following data structure definition to describe by concrete data zone:
White space upper left corner coordinate: (x, y);
White space width: wldth;
White space height: helght;
The height of having been filled by concrete " data zone " in the white space: subheight.
Begin at automatic format setting, at first define or generate the white space of maximum, be described below:
White space upper left corner coordinate (X, y)=(0,0);
White space width width=application program subwindow client area width;
Height=+ is infinite for the white space height;
The height Subheight=0 that has been filled by concrete " data zone " in the white space
But, when having served as the graphics field, and figure to place attribute be that a left side or the right side are when putting situation, the white space that will on current white space, cut apart the symbol filling that makes new advances, as shown in Figure 2, it is the synoptic diagram of new white space in the inventive method, and it is described as (being changed to example with a figure left side):
New white space upper left corner coordinate (x, y)=(graphic width is put on a left side, current layout position);
Graphic width is put on the new current white space width of a white space width width=width-left side;
The figure height is put on a new white space height height=left side;
The height Subheight=0 that has been filled by concrete " data zone " in the new white space
When generating new white space, original white space node should be preserved into storehouse, the white space node of preserving originally will be ejected when full, and be changed to current and continue filling when new white space is filled.
(2) this paper zone (TextArea): one of the physical resource area type in zone is used for filling in the blanks in the format setting process, it be because of same alike result (as font, font size, font, modification attribute etc.) form by the occupied rectangular area of character string this paper, so be called this paper zone.We use following data to define to represent:
The upper left corner, this paper zone coordinate: (x, y);
This paper peak width: width;
This paper region height: height;
This paper area characters string owner pointer: pstr;
This paper area characters string length: len
It is noted that character string this paper of same alike result, when breadth extreme that its display width can hold greater than current line, just must be split into two or more this paper zones.
As shown in Figure 3, it is the demonstration synoptic diagram in " this paper zone " in the inventive method.Character string " Thedatabase used for this article is very simple, containing one table, named Products." be the identical a string this paper of attribute; but owing in current line, can not hold whole character string; so be split into several character strings; character string " The database used for " is this paper zone; and character string " this article is very " is another this paper zone, " simple, containing one " is the 3rd this paper zone; " table, named Products." be the 4th this paper zone.
(3) graphics field: one of the physical resource area type in zone that in the format setting process, is used for filling in the blanks, it be embedded in figure and form by the occupied rectangular area of graphic picture, so be called the graphics field.We use following data to define to represent:
The upper left corner, graphics field coordinate: (x, y);
Graphics field width: width;
Graphics field height: height;
Graphics field graphic file name owner pointer: pstr.
As shown in Figure 4, it is the demonstration synoptic diagram of graphics field in the inventive method, and Height2 is the figure height, and w2 is a graphic width.
Set type for figure, placing attribute when figure is that upper, middle and lower generates the graphics field when putting, and type-setting mode just can not be divided into figure a plurality of graphics fields with character string this paper; Put attribute for figure and be a left side or the right figure of putting, we can generate new white space storehouse node, and its area size and coordinate figure just in time are that the represented zone of current white space storehouse top node crops remaining zone, the red zone of the occupied square of right figure.
(4) white space storehouse: served as a left side or the right side and put figure and generate new white space, original scene to be preserved, after disposing, to recover the scene of original preservation new white space, we use stack architecture to preserve and recover on-the-spot, storehouse node data organization definition is with the white space data structure definition, and we use following data to define to represent:
The white space upper left corner coordinate that the storehouse node is represented: (x, y);
The white space width that the storehouse node is represented: width;
The white space height that the storehouse node is represented: height;
The son height of oneself filling of the white space that the storehouse node is represented: SUbheight;
The next node that the storehouse node is pointed: next;
We define stack head pointer: glpStackHead simultaneously.
In addition, we are called the action that generates cross chain head new in the netted data chainning and open up new " OK ", in the time will opening up new " OK ", and processing below needing to do:
* adjust the ordinate value in each data zone in current " OK ", set type in the hope of alignment thereof on request.
* calculate this full line data rectangular area height of " OK ", concerning about put the graphics field that figure forms filling rectangular area stack architecture, the height of having represented it, and its actual putting position is at current line, and at next line, so it highly is 0.
* the full line of one's own profession is highly added up the son height of having filled into current white space, if the filling of current white space the region height of degree more than or equal to current white space, then the current stack node eject is discharged, revise simultaneously the new storehouse node that is not pressed into storehouse and about put figure the zone.
* before opening up newline, whether disconnected lastrow has is put situation and generates new white space storehouse node and have and then be pressed into storehouse about figure.
* when mark chain after scan process has finished, if still have the residue node in the white space storehouse, then with its ejection and release.Each " OK " (Line) the height sum of node is the overall height of this webpage.
Therefore, by above description as can be known, white space storehouse system is used for writing down the node content of old white space when new white space produces, the characteristic of utilizing storehouse last in, first out (Last In First Out), and in order to the scene of the new white space after recovering to set type.
Please refer to Fig. 5, according to above nominal definition, the representation that we design image mixed character typeset is a reticulate chain structure in length and breadth, comprising writing down with the attribute of each data in the delegation and the node of content, reach the horizontal data chainning of relativeness between node, and the vertical head node chain that links the head node of each horizontal data chainning.Therefore the representation of image mixed character typeset is: LineHead → Linel → Line2 → ... → LineN → ... → LineTail represents vertical head node chain, wherein Linel (or Line2 or LineN) represents the head node of each row, and the delegation data of the horizontal data chainning that the head node of each row is drawn for being formed by graphics field or this paper zone, Object node wherein is to unite for the data zone of graphic documentation is regional and this paper data zone and other type, and its attribute attr has represented the data type and the content of the information data area domain node that it is pointed.
The system health that is applied in according to the inventive method on a kind of browser of HPC host platform is done a brief description.As shown in Figure 6, it is a browser overall architecture synoptic diagram, according to synoptic diagram as can be known:
1. browser is at first downloaded (step 601) to figure in the webpage or this paper data;
