Embodiment
For making purpose of the present invention, technical scheme clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
The present invention is a kind of print preview method, and its basic thought comprises:
A. receive the Print Preview sign on that the user sends, piecemeal reads corresponding data set from data source, and calculates and preserve the layout information of the page of printing this data set according to the total amount of data of this data set;
B. receive the Print Preview request that the user sends, and, from data source, obtain and preserve the corresponding data set content of this request, and the data set content of preserving is shown by preview page according to the layout information of being preserved.
Be example still below, print preview method of the present invention is described with IPMS.
As shown in Figure 2, the present embodiment print preview method may further comprise the steps:
When the user prints preview at needs to institute's browsed content,, the Print Preview sign on is sent to IPMS by modes such as click Print Preview buttons; After IPMS receives the Print Preview sign on, from the instruction that receives, obtain the information of Print Preview target.
Thereafter, IPMS is according to the internal memory situation, from the data source of user place computing machine, progressively read the full content with the corresponding data set of information of Print Preview target, and determine the total amount of data that content comprised that gets access to, for example the line number of this data set and columns etc.Particularly, as shown in Figure 3, the full content of this place reading of data collection and totalize according to the amount method comprise:
Step 2021. is according to the internal memory situation, determines the maximum amount of data M of the data set content that at every turn reads.
In order to utilize less internal memory to get access to the data volume of data set full content, according to memory headroom, the maximum amount of data M of definite data set content that at every turn reads is so that the read operation in the restriction subsequent step in this step.
Step 2022～2023. is removed the data set content of preserving in the internal memories, access data sources, from the data set content of the corresponding data centralization reading of data of Print Preview sign on amount less than M, be kept in the internal memory; Calculate and write down the data amount information of the data set content of being preserved.
For the data set content stores that subsequent reads can be got in internal memory, so this place at first abandons the data set content of preserving in the internal memory.Then, in order to adapt to memory headroom, the corresponding data centralization of Print Preview target information that this place comprises from the Print Preview sign on of sending with the user reads the data set content that is no more than maximum amount of data M, and the data set content that reads is kept in the internal memory.Thereafter, IPMS calculates the data set content of being preserved in the internal memory, determines its data amount information, and for example: line number, columns etc. are recorded in the data amount information that calculates in the internal memory again.
Step 2024～2026. judge whether this data centralization exists the content that is not read, if, the content that then turns to this data centralization not to be read, and return execution in step 2022; Otherwise,, determine the total amount of data of this data set full content according to the data amount information of record.
If still have the content that is not read with the corresponding data centralization of printing sign on, show that then IPMS does not get access to the full detail of this data set, therefore will read that part of content that this data centralization of target diversion is not read, and return execution from reading the operation of record data amount information; If the full content of this data centralization all was read, then IPMS draws the total amount of data of this data set full content with the total data amount information addition of writing down in the internal memory.
So far, finished the full content of reading of data collection and totalize according to the amount flow process.
After having determined total amount of data, IPMS utilizes the print area of determined total amount of data and each preview page, calculates and preserve the layout information of the page of printing this data set.
So-called layout information comprises the number of pages of printing this data set and every page the start element lattice numerical value (i that represents with two-dimensional array
N is initial, j
N is initial) and every page end unit lattice numerical value (i
N finishes, j
N finishes), i wherein
N is initialAnd i
N finishesRepresent the initial row and the end line of n page or leaf respectively, j
N is initialAnd j
N finishesRepresent the initial row and the end column of n page or leaf respectively.
The method of calculating the number of pages of printing this data set in the present embodiment is:
The print area of total col width of head office's height * data set of number of pages=data set/every page
=(word height+go up spacing+following spacing) * total line number * (word wide+left spacing+space on right)
* total columns/(every page printing height * every page print span).
Calculating every page the start element lattice numerical value and the method for end unit lattice numerical value in the present embodiment comprises:
A. every page printing height is rounded divided by the word height, after going up spacing and following spacing sum, obtain every page of line number x that can print, every page print span is rounded after divided by wide, left spacing of word and space on right sum, obtain every page of columns y that can print;
B. determine start element lattice numerical value and end unit lattice numerical value, wherein:
i
N finishes=i
N is initial+ x-1,
j
N finishes=j
N is initial+ y-1.
For instance, as shown in table 1, total line number of tentation data set content is 6 row, and total columns is 9 row, the word height is 1, word is wide to be 0.8, and last spacing is 0.5, and following spacing is 0.5, left side spacing is 0.5, space on right is 1.5, then the head office of data set content high in: (1+0.5+0.5) * 6=12, total col width of data set content equals: (0.8+0.5+1.5) * 9=25.2.
| A | B | C | D | E | F | G | H | I |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| A1 | B1 | C1 | D1 | E1 | F1 | G1 | H1 | I1 |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| A2 | B2 | C2 | D2 | E2 | F2 | G2 | H2 | I2 |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Table 1
The printing of supposing every page highly is 6, and print span is 8.4, and then every page print area is: 6 * 8.4=50.4.
Therefore, the required number of pages of the data set content shown in the type list 1 is: 12 * 25.2/50.4=6 page or leaf;
Every page of line number x=[6/ that can print (1+0.5+0.5)]
Round=3 row;
Every page of columns y=[8.5/ (0.8+0.5+1.5) that can print]
Round=3 row.
Wherein, every page start element lattice numerical value is respectively:
Every page end unit lattice numerical value is respectively:
j
1 finishes=i
1 is initial+ x-1=1+3-1=3, j
1 finishes=j
1 is initial+ y-1=1+3-1=3;
i
2 finish=i
2 is initial+ x-1=1+3-1=3, j
2 finish=j
2 is initial+ y-1=4+3-1=6;
i
3 finish=i
3 is initial+ x-1=1+3-1=3, j
3 finish=j
3 is initial+ y-1=7+3-1=9;
i
4 finish=i
4 is initial+ x-1=4+3-1=6, j
4 finish=j
4 is initial+ y-1=1+3-1=3;
i
5 finish=i
5 is initial+ x-1=4+3-1=6, j
5 finish=j
5 is initial+ y-1=4+3-1=6;
i
6 finish=i
6 is initial+ x-1=4+3-1=3, j
6 finish=j
6 is initial+ y-1=7+3-1=9.
Step 203～206. receive the Print Preview request that the user sends, and whether IPMS judges to preserve in the internal memory with this asks corresponding data set content, if the data set distribution of content corresponding with this request that then will preserve is in corresponding browsing pages; Otherwise, from data source, obtain with this and ask corresponding data set content, be kept in the internal memory, and with the data set distribution of content of preserving in corresponding preview page.
The Print Preview request at this place is used to show the user to being presented on the demand of the preview page on the computer screen, and this request comprises that the page shows request, preview page handoff request etc.Wherein, the page shows the preview page display mode that comprises user's selection in the request, for example: and single page or multipage, and under the situation of selecting multipage to show, indicate the number of pages that once shows; The preview page handoff request by the rolling of user by mouse, promote scroll bar and in specifying preview page input need the modes such as number of pages of preview to send, be used to show the variation of user to the demand of preview page.
When IPMS receives the Print Preview request that the user sends by the operating system in its place computing machine, determine the data set content of user's needs preview according to the request that receives.Because behind the layout information that calculates this data set full content, preserve a part of data set content in the internal memory, so this place judges to the data set content of preserving in the internal memory, determine whether to exist and the corresponding data set content of Print Preview request.If exist, then need not access data sources, but directly will ask corresponding data set content to put into the corresponding page with this in the internal memory; If there is no, then according to the preview page information of carrying in the Print Preview request, access data sources is obtained corresponding data set content.
IPMS obtains the data set content from data source method is: IPMS is according to the preview page information of carrying in page layout information of preserving and the Print Preview request, the start element lattice information and the end unit lattice information of the definite data set content that will obtain, then, in this data centralization that data source is preserved the definite start element lattice information and the data set contents extraction of end unit lattice information correspondence are come out, and be kept in the internal memory.
Be example still, suppose that the preview page information of carrying in the Print Preview request shows that it is the 4th page that the user needs the page of preview, then, determine that the 4th page start element lattice information is: i according to the page layout information of determining in the step 202 with the data set content shown in the table 1
4 is initial=4, j
4 is initial=1; End unit lattice information is: i
4 finish=6, j
4 finish=3.Therefore, IPMS arrives the content between (6,3) from this data centralization extraction from (4,1), and is kept in the internal memory.
After the data set content of storage print preview request correspondence, IPMS puts into the data set content of being stored in the corresponding preview page, so that be shown to the user in the subsequent step.
By foregoing description as can be seen, originally be in and preserve a part of data set content in the internal memory, avoided receiving the Print Preview request at every turn and all will conduct interviews, saved the time of Print Preview flow performing in the present embodiment data source.
The preview page that step 207. will comprise with the corresponding data set content of Print Preview request is shown to the user.
After being put into preview page with the corresponding data set content of Print Preview request, IPMS shows above-mentioned preview page by graphic user interface.
