![]() Enter the “merge pdf” online tool conversion page through the AbcdPDF platform. If you need to use PDF online services to merge, you don’t need to solve the above problems yourself, Merge PDF has provided a perfect solution, and it is free forever. ![]() In this case, it can be helpful to find the position of the key character in the string search and specify the position relative to it. In this case, search for ( 1 ) keywords only on the first page, ( 2 ) keywords only on the last page, and ( 3 ) keywords common to the same data, and determine page breaks. B ‘s start page will change according to Mr. Once the start page is determined, we can get Mr. It can be handled by specifying the range to fetch considering the maximum data. In this case, Merge PDF needs to prepare a strategy to solve the above problems, the following is the technical solution:Ĭonsidering the situation with the largest amount of data, it can be processed by specifying a location so that all data can be retrieved. The following situations change the position of the text: However, in real data, the location may change. If the position of the text is fixed, you only need to specify the range to be extracted to extract the text. After the conversion of the coordinate system is completed, merge pdf will refer to the original number of pages to perform pagination. The coordinate values checked by the viewer are converted according to the coordinate system of the command. In our previous product example, the PDF viewer and text extraction commands had different length units and different origin locations. Specifically, it depends on the location of the origin, the orientation of the x/y axes, the units of length, and the rotation of the page. It depends on the coordinate system, not just the coordinate values. If the coordinate value of a given rectangle is “upper left (6, 8) – lower right (10, 14)” as shown in the figure below, where is the range of the rectangle? The first point is the coordinate system of the tool to be used.
