The configuration of the cell longitudinal combination is as in fig. 3, the 4 th column of the 5 th row and the 3 rd column of the 6 th row are combined, and the 5 th column of the 5 th row and the 4 th column of the 6 th row are combined. The requirements for vertical merging are: in adjacent rows, the abscissa of the cells participating in merging must be equal, and the cells participating in merging are configured with the same merging identifier. Therefore, the line print styles "style 4" and "style 5" configure "merge = 0", "merge = 2", and 2 line print styles use the same aspect ratio "xln = 60", "xln = 67", and "xln = 100". After merging, 2 new line printing styles "style 10" and "style 11" are defined for use by the merged item.
The cells are transversely combined and not really combined (virtual combination), only the overlapped edges of the cells participating in combination are not printed by configuring frame parameters, and the printing position is kept unchanged. And performing transverse merging on the merged item after the longitudinal merging, and configuring "edge = 14" in "style 10" and "edge = 13" in "style 11" to achieve the effect that the items are in the same cell as the "capital sum" and "sanbai round" in fig. 3.
The underlined configurations are "guest signature" in fig. 3 and "order remark", "cashier" in fig. 5. There are two configuration methods, one is to configure the data type of the print item as a line, and the alignment is the fourth print item configuration of "style 0" in the following manner; the other is that the border parameter of the configuration cell is 4, i.e. only the lower border, such as "style 5", is displayed.
After the printing template configuration is completed, the printing service interface 2 is called to upload the printing template, the printing service receives the printing template, and the validity of the printing template and the correctness of parameter values are verified by using the rule of the template configuration, such as: value range, etc.; after the verification is passed, the template name is used as a file name and is saved in a hard disk of a server (or a database and the like), meanwhile, a line printing style list (Lst-LineStyle) is opened in a memory, and the printing template is saved for subsequent use.
As in S102 in fig. 1, the print data must be labeled with a line style label before printing using the previously configured print template. And respectively labeling the data of the hotel check-in receipt and the data of the invoice.
"printemplate" indicates the template name used by the print data, "head" marks which data lines belong to the fixed page head, "tail" marks which data lines belong to the fixed page tail, "body" marks which data lines belong to the page body, "style" marks the line style name used by the line, and "items" lists the printed data items sequentially from left to right, ensuring that the number of the data items is the same as the number and the sequence of the print items configured in the line style.
After S102 is completed, whether the printing service interface 3 is called to request printing or the interface 4 is called to request printing preview, the printing core algorithm is completed S103, then S104 is executed to call the basic printing method, and finally S105 is executed to preview.
The S103 print core algorithm is explained in detail below with reference to fig. 8. The algorithm opens up several pools of data in memory: a pre-pagination cell list (Vec-Linecells) and a print item list (Vec-LineItems) for storing intermediate results, wherein the cell structure is defined by: the system comprises a frame, a row number, a column number, a combined identifier, an upper left point coordinate and a lower right point coordinate; the print item structure is defined by: frame, line number, column number, merging identifier, upper left point coordinate, lower right point coordinate, data type, alignment mode, font, line width and line type. A print page list (Lst-printPage) for storing the result of the algorithm processing and printing, wherein a print page data structure is defined by: total number of pages, current page number, list of print items, and list of cells. The current print page prints a line segment list (Vec-LineSeg), and a data structure defines coordinates of both ends of the line segment.
S200, printing initialization, emptying Vec-LineColls and Vec-LineItems, starting a page body line number =0, starting upper margin of the page body is equal to upper margin of the page, lower margin of the page body is equal to lower margin of the page, traversing printing data starting line number =0, line top height of a current processing line (distance between the upper margin of the line and the upper margin of the page) =0, and the action domains of the parameters are all the following steps.
S201, processing the first line of the page in the print data, taking out the first line of the data from the first line of the print data, delivering the line number, the line top height, the line print style name and the in-line print item list to the line data processing module S300, updating the line top height after the data processing module finishes processing and returning the line top height, adding 1 to the line number, taking out the next line of the data from the first line of the print data page, and repeating the operation until the first line of the page is processed. At this time, the height of the top of the line = the margin of the page body, and the line number = the initial line number of the page body. If there is no top line in the print data, the step is skipped.
In step S202, page-wise lines in the print data are processed in the same manner as in step S201, except that line data are sequentially extracted from page-wise lines in the print data.
And S203, processing the page tail lines in the printing data, wherein the processing step is the same as S201, except that the line data are sequentially taken out from the page tail lines of the printing data, and the initial value of the reset line top height is equal to the page height minus the page bottom margin.
S204, the tagged printing data submitted by the interface 3 is processed, and the processed intermediate results are stored in Vec-Linecells and Vec-LineItems, namely the printing item and the cell coordinate in the page body are the non-paged coordinate, and the printing item and the cell coordinate in the page head and the page tail are the page internal coordinate. The step of processing the merging item comprises the following steps:
and taking the printing style name of the merging item line and the data of the merging item from the printing data 'mergeremems', obtaining the style content (merging identification, font and the like) from Lst-LineStyle according to the printing style name, and traversing Vec-Linecells and Vec-LineItems according to the merging identification to obtain the cells and the printing items participating in merging.
Arranging the cells and the printing items participating in merging from small to large according to the line numbers respectively, failing merging if the line numbers are discontinuous, comparing whether left and right horizontal coordinates are equal, failing merging if the left and right horizontal coordinates are not equal, taking the top side coordinates of the cells and the printing items with the minimum line numbers and the bottom side coordinates of the printing items with the maximum line numbers as the coordinates of merging items after merging verification passes, enabling the line numbers of the merging items to be equal to the minimum line number, deleting the cells and the printing items participating in merging from Vec-Linecells and Vec-LineItems, and inserting the merging items into the cells and the printing items.
And S205, performing line paging on the page body, emptying a printing page list (Lst-printPage) before paging, wherein the total number sum of the initialized pages =1, the current page number no =1, the line number rowno = the initial line number of the page body, creating a list item of the new printing page, and setting the page number equal to 1. All cells with line number = rowno are taken from Vec-LineCells, all print items with line number = rowno are taken from Vec-linesites, and deleted therefrom to reduce the number of subsequent traversals.
And comparing the vertical coordinates of the top edge and the bottom edge of the taken out unit cell with the lower margin of the page body, and if the unit cell larger than the lower margin of the page body exists, the page of the line needs to be changed.
When the page needs to be changed, adding 1 to the total page number, adding 1 to the current page number, calculating the offset = the vertical coordinate of the top edge of the current line-the upper margin of the page body, scanning Vec-Linecells and Vec-LineItems, and updating the vertical coordinates of the top edge and the bottom edge of the cell and the printing item with the line number larger than the current line number and smaller than the tail line number by using the offset. Newly creating a list item of a printing page, adding cells and printing items of a page head, a page tail and a current line, and adding a current page number.
When the page does not need to be changed, the cells and the printing items of the current line are directly added into the list items of the current printing page.
And adding 1 to the line number, and repeating the operations until the line number is equal to the initial line number of the page tail, and ending the paging operation.
And S300, the line data processing is used for calculating coordinates of all cells and printing items in the line, firstly calculating the abscissa of the printing items, and then calculating line height defined by line height and line style and transmitted line top coordinates according to the data of the printing items to determine the ordinate of each printing item. The print item coordinate calculation process is as follows:
the style parameter is taken from Lst-LineStyle according to the line printing style name: line borders, line heights, and a print item style list, the line heights being initially defined by the style.
Calculating the horizontal coordinate of the cell: left abscissa = left margin when the cell is the first, and left abscissa = right abscissa of the previous cell when the cell is not the first; right abscissa = round ((page width-left margin-right margin) × aspect ratio) + left abscissa.
Print item abscissa calculation: the left abscissa = the left abscissa + column pitch of the corresponding cell, and the right abscissa = the right abscissa-column pitch of the corresponding cell.
And (4) line height calculation, namely firstly obtaining the text line number of the printing item from a line-feed character in the text data of the printing item, then calculating whether each line needs to be divided into lines according to the width of the font defined by the style and the width of the printing item, finally multiplying the total line number by the height of the font to obtain the height of the printing item, and updating the line height if the total line number is larger than the line height defined by the line style.
The incoming row top coordinate + row spacing 2+ row height = the row cell base ordinate = the new row top coordinate as the row top coordinate parameter for calculating the next row.
And finally adding the cells and the printing items with the calculated coordinates into Vec-Linecells and Vec-LineItems as printing intermediate results.
S104, executing page printing, wherein the printing work is divided into two types: one type is print item and the other type is line segment printing. After the core printing algorithm is completed in S103, the print item with the print coordinate position and the form of the cell page are stored in the print page list (Lst-PrintPage).
Calling a corresponding basic printing method according to the data type of the printing item in the page, if the printing item is of the page type, replacing a page wildcard character in a printing text by using the total page number and the page number of the printing item, wherein the total page number is equal to the length of an Lst-printPage list; the text type and the line type call DrawText, MoveTo and LineTo of CDC; the two-dimensional code type also converts the text into a two-dimensional code picture, and calls a BMP picture printing method of CDC.
And (3) printing the line frame in the page, namely clearing Vec-LineSeg, determining edges needing to be printed in four edges of the cell according to frame parameters of the printing style of the printing item line, adding the edges to a printing line segment list (Vec-LineSeg) of the current printing page, and then traversing the Vec-LineSeg to perform duplication removal on all printing line segments in the page. There are two types of deduplication: one is that the horizontal line segment is removed from the duplication, the vertical coordinate is equal to the current line segment, and other line segments of which the left end point of the horizontal coordinate is more than or equal to the current line segment and the right end point is less than or equal to the current line segment are deleted from the Vec-LineSeg; and the other is that the longitudinal line segments are subjected to de-duplication, no partial coincidence exists, and other line segments with the same end point coordinates are only required to be deleted from the Vec-LineSeg. And finally calling a line segment printing basic method to print the line segments in the Vec-LineSeg one by one.
After receiving a print preview request of a client through an interface 4, the printing service uses a printing core algorithm to process all print data and then stores the print data in a print page list (Lst-printPage), then converts the coordinates of a printing item and a cell in printing equipment into coordinates on a screen, prints a head page into a BMP picture by using memory printing, converts the BMP picture into a JPG picture, sends the coded BASE64 together with the total number of pages to the client for display, and the client realizes print preview of other pages by sending a print preview request with page number parameters.
It can be seen from this embodiment that different printing templates can be deployed at the printing server according to different printing service requirements, and the fine adjustment of the printing format details is greatly facilitated by using the print preview function in the process of customizing the printing template. The printing template file can be directly edited by customizing the printing template, and the printing template file can be automatically generated by drawing and editing the graph by adopting the currently popular HTML5+ CANVAS. In practical application, the printing format can be conveniently and flexibly adjusted by adjusting the parameters of the printing template and loading the parameters to the printing server. Therefore, the invention has good use value in table data printing
