if the file type is a fourth type file, namely a PDF file, the PDF file is analyzed to obtain fourth data information, namely information such as the type, attribute, file content and the like of the PDF file.

S400, converting the file:

and executing corresponding file conversion operation according to the file types:

if the file type is a first type file, namely a text file, acquiring analysis parameters to obtain a value of a conversion mode in the analysis parameters:

if the value of the conversion mode is the first text conversion mode, calling the first text file conversion mode to execute text file conversion operation on the first data information to obtain a target file;

if the value of the conversion mode is the second text conversion mode, calling the second text file conversion mode to execute text file conversion operation on the first data information to obtain a target file;

to explain the present invention more clearly, it is exemplified here that, when the conversion schema is the first text conversion schema, the first data information is converted by the schema of text parsing and element processing, the first data information is converted into the target PDF file by QPrinter or QpdfWriter in QT; when the conversion mode is the second text conversion mode, the first data information is converted into the target PDF file by QWebEngine in QT.

If the file type is a second type file, namely a picture file, second data information and analysis parameters are obtained, and picture file conversion operation is performed on third data information according to data in the analysis parameters to obtain a target file;

to explain the present invention more clearly, it is assumed that the third data information is converted into a PDF file by setting in the parsing parameters, and then the third data information is converted into an Image object by openCV or QT native method, and the Image object is converted into a target PDF file by QPrinter or QpdfWriter.

If the file type is a third type of file, namely a webpage file, acquiring analysis parameters to obtain a value of a conversion mode in the analysis parameters:

if the conversion mode is the first webpage conversion mode, calling the first webpage file conversion mode to execute webpage file conversion operation on the third data information to obtain a target file;

if the conversion mode is the second webpage conversion mode, calling the second webpage file conversion mode to execute webpage file conversion operation on the third data information to obtain a target file;

to explain the present invention more clearly, it is exemplified herein that when the conversion mode is the first netpage file conversion mode, the second data information is converted into the target PDF file by QWebEngine in QT; and when the conversion mode is the second webpage file conversion mode, converting the second data information into a target PDF file through a wkhtmltopdf tool.

If the file type is a fourth type file, namely a PDF file, acquiring analysis parameters to obtain a value of a conversion mode in the analysis parameters:

if the conversion mode is the first PDF file conversion mode, calling the first PDF file conversion mode to execute portable file conversion operation on the fourth data information to obtain a target file;

if the conversion mode is the second PDF file conversion mode, calling the second PDF file conversion mode to execute portable file conversion operation on the fourth data information to obtain a target file;

if the conversion mode is the third PDF file conversion mode, calling the third PDF file conversion mode to execute portable file conversion operation on the fourth data information to obtain a target file;

when the first PDF file conversion mode is called to execute portable file conversion operation on the fourth data information and the second PDF file conversion mode is called to execute portable file conversion operation on the fourth data information, the file size of a target file in the analysis parameters is obtained, the file size of the target file is compared with the file size of an original file, and if the two file sizes are the same, the portable file conversion operation is directly executed; if the sizes of the two files are not equal, a file size conversion strategy is called to convert the file size firstly, namely a set safe cutting value is obtained, and a cutting threshold value is set according to the safe cutting value; calculating the coordinate of the cutting area according to the cutting threshold and the coordinate information of the original file; cutting the file converted from the original file according to the cutting area coordinates to obtain a cut file; then obtaining the size information of the target format file, the picture scaling and stretching ratio, and the first slope distance and the first offset angle of the cut file and the target format file, and calculating a target coordinate according to the data; adding the cut file to a target format file according to the target coordinate to obtain a target file;

to explain the present invention more clearly, it is exemplified herein that, when the conversion mode is the third PDF file conversion mode, the fourth data information is converted into the target PDF file by the MuPDF; when the conversion mode is a first PDF file conversion mode, namely a capture mode, converting fourth data information into an Image object through an ImageMagick picture-to-QT native method or openCV picture analysis, then calling a file size conversion strategy to cut and convert the Image object, and converting the cut Image object into a target PDF file through QPrinter or QpdfWriter; and when the conversion mode is the second PDF file conversion mode, converting the fourth data information into an Image object through a C + + class library Poppler, calling a file size conversion strategy to perform cutting conversion on the Image object, and converting the cut Image object into a target PDF file through QPrinter or QpdfWriter.

The file size conversion strategy is explained by way of example with reference to FIG. 5: in fig. 5, a is a clipping range, b is a skew distance, c is an offset angle, a safe clipping value is set to be a, that is, a critical safe area is reserved in fig. 5, and a clipping threshold value is set to be S according to the safe clipping value a, wherein S is greater than or equal to a; setting the coordinates of the original region as { (x1, y1), (x2, y2) }, the cropping range is { left, top, right, bottom }, then the coordinates of the cropping region can be obtained as { (x1+ left S%, y1+ top S%), (x2-right S%, y2-bottom S%) }, the coordinates of the new sheet are set as { (a1, b1), (a2, b2) }, the zoom ratio is set as Z, the skew distance is set as L, the offset angle is i, then the target coordinates can be calculated as { (a1+ L cos) (angle), (b1+ L sin), (angle), (a1+ L) + + (x 638%), (Z) + (2%) and (Z + x + -%) (2 +) (x — int). And attaching the clipping file to the target format file through the target coordinate to obtain a target file.
