步骤4.1.2、转换，同一测量单位下OFD文件的页面宽度值为w；OFD文件中内容对象的坐标、宽度值、高度值为(x1、y1)、w1、h1；符合基准的位置信息中对应的坐标、宽度值、高度值为(x2、y2)、w2、h2；Step 4.1.2, conversion, the page width value of the OFD file under the same measurement unit is w; the coordinates, width value, and height value of the content object in the OFD file are (x1, y1), w1, h1; in the position information that meets the benchmark The corresponding coordinates, width value, and height value are (x2, y2), w2, h2;
两者之间的转换公式为：The conversion formula between the two is:
scale＝1024/w，scale=1024/w,
x2＝x1*scale，x2=x1*scale,
y2＝y1*scale，y2=y1*scale,
w2＝w1*scale，w2=w1*scale,
h2＝h1*scale；h2=h1*scale;
比如300*300页面转换成1024的坐标，内容对象的坐标、宽度值、高度值是(20、20)、30、30转换后的绘制参数表示为(x3、y3)、w3、h3，这个时候就是x3＝1024/300*20；For example, a 300*300 page is converted to 1024 coordinates, and the coordinates, width value, and height value of the content object are (20, 20), 30, and 30. The converted drawing parameters are expressed as (x3, y3), w3, and h3. At this time That is x3=1024/300*20;
内容对象为路径对象时的转换过程为：The conversion process when the content object is a path object is:
步骤4.2.1、读取内容对象的位置信息，将内容对象的位置信息转换成符合基准的位置信息，位置信息包括起始点的坐标和终点的坐标；Step 4.2.1, read the location information of the content object, convert the location information of the content object into the location information conforming to the reference, the location information includes the coordinates of the starting point and the coordinates of the end point;
步骤4.2.2、转换，同一测量单位下OFD文件的页面宽度值为w；Step 4.2.2, conversion, the page width value of the OFD file under the same measurement unit is w;
OFD文件中内容对象的起始点的坐标为(x3、y3)，终点的坐标为(x4、y4)；The coordinates of the starting point of the content object in the OFD file are (x3, y3), and the coordinates of the end point are (x4, y4);
符合基准的绘制参数中对应的起始点的坐标为(x5、y5)，终点的坐标为(x6、y6)；The coordinates of the corresponding starting point in the drawing parameters conforming to the datum are (x5, y5), and the coordinates of the end point are (x6, y6);
两者之间的转换公式为：The conversion formula between the two is:
scale＝1024/w，scale=1024/w,
x5＝x3*scale，x5=x3*scale,
y5＝y3*scale，y5=y3*scale,
x6＝x4*scale，x6=x4*scale,
y6＝y4*scale；y6=y4*scale;
步骤5、生成基础的版式数据流文件结构体；Step 5, generating a basic layout data flow file structure;
步骤6、将内容对象、新的相关信息以及资源对象写入版式数据流文件结构体中，其中资源对象在写入版式数据流文件结构体的过程为：Step 6. Write content objects, new related information and resource objects into the layout data flow file structure, wherein the process of resource objects writing into the layout data flow file structure is:
S6.1.1、判断版式数据流文件结构体中是否包括资源对象，若含有资源对象则进入S6.1.2；S6.1.1. Determine whether the format data flow file structure includes resource objects, and if it contains resource objects, enter S6.1.2;
S6.1.2、获取资源对象的hash值，判断版式数据流文件结构体中是否存在与该资源对象的hash值相同的资源对象，若存在不重复添加，若不存在则进入S6.1.3；S6.1.2. Obtain the hash value of the resource object, and judge whether there is a resource object with the same hash value as the resource object in the layout data flow file structure. If it exists, do not add it repeatedly; if it does not exist, go to S6.1.3;
S6.1.3、生成与该资源对象对应的id，将id与该资源对象分别作为key和value，以<key,value>键值对的形式写入版式数据流文件结构体中，同时，将页面与资源对象的引用关系中涉及该资源对象的对应关系修改为该id；S6.1.3. Generate the id corresponding to the resource object, use the id and the resource object as key and value respectively, and write them into the layout data flow file structure in the form of <key, value> key-value pairs, and at the same time, write the page The corresponding relationship involving the resource object in the reference relationship with the resource object is changed to the id;
步骤7、将每个页面的对应关系写入文件的配置信息文件，docinfo包含了文件的信息、标题、描述、子标题、版本号以及作者等；pages包含了文件的页码，以及path代表文件内容名字，根据path去找当前页的具体内容信息，id只是唯一标识，pages包含多页，其对应的的脚本信息的格式如下：Step 7. Write the corresponding relationship of each page into the configuration information file of the file. docinfo includes file information, title, description, subtitle, version number, author, etc.; pages includes the page number of the file, and path represents the content of the file Name, according to the path to find the specific content information of the current page, id is only a unique identifier, pages contain multiple pages, and the format of the corresponding script information is as follows:
步骤8、最后将页面内容文件和文件的配置信息文件一起打包压缩成版式数据流文件。这样使得应用版式数据流文件的***能够适配OFD文件。Step 8. Finally, the page content file and the configuration information file of the file are packaged and compressed into a layout data stream file. This enables systems using format data flow files to adapt to OFD files.
