Detailed Description
Fig. 1 shows a schematic flow chart of an embodiment of a signature imaging processing method based on an OFD document. As shown in fig. 1, the method comprises the following steps:
step 110: and extracting a target area containing user signature information from the target OFD document, and performing image conversion processing on the target area to obtain a target signature image.
Wherein, (1) the target OFD document is: an OFD document requiring a user to sign, the content of which is not limited. (2) The user signature information is: the signature content obtained by the user signing by writing means (such as pencil means, drawing means, etc.) is not limited to chinese, english, symbols, etc. (3) The target area is: an area containing user signature information. In this embodiment, the target area is: a minimum rectangular area containing the user signature information; other types of regions are possible, and need only contain complete user signature information, without limitation. (4) The manner of image conversion processing includes, but is not limited to: WEB picture-to-picture technology (JavaScript, canvas picture-to-picture, etc.), c++ picture-to-picture, PHP picture-to-picture, etc. (5) The target signature image is: an image containing user signature information.
Step 120: acquiring image attribute information of the target signature image, acquiring position information of the target area in the target OFD document, and carrying out format integration on the image attribute information and the position information based on OFD document standards to obtain integrated format information in an xml format.
Wherein (1) the image attribute information includes, but is not limited to; length and width information. (2) The position information is: and (3) the position coordinates of the target area in the target OFD document. (3) The OFD document standard is: the specific details of the national format document format specification (OFD) standard are not described in detail herein. (4) The process of integrating the formats of the image attribute information and the position information comprises the following steps: the picture element is added to the OFD file in a stamp annotation object, and written into xml in the target OFD file by setting a boundary to which the picture element is added, including coordinates (position information) and width and height (image attribute information) of the picture in the page, and a transformation matrix CTM attribute of the picture object.
In this embodiment, the upper left corner of the preset area is used as the origin (0, 0), the X axis extends rightward, and the Y axis extends downward.
Step 130: and storing the integrated format information and the target signature image into the target OFD document to display the user signature information in the OFD document in an image form.
The method comprises the steps of (1) storing integrated format information into the animation xml of a corresponding page under Pages of a target OFD document; the target signature image is stored to the target OFD document (in the resource folder Res).
Preferably, the step of extracting the target area containing the user signature information from the target OFD document includes:
when a user signs in a preset area of the target OFD document, extracting the user signature information in the preset area, and determining the target area in the preset area.
The preset area is as follows: and a preset area for signing by a user in the target OFD document. For example, a text box (container) is reserved at the end of the document content for signing.
Specifically, canvas is taken as an example (canvas itself does not have drawing capabilities, and is a canvas itself, which is a container). The drawing capability is completed based on the canvas renderingcontext2D object returned by html5 getContext ("2D"). canvas is a two-dimensional network with the upper left corner (0, 0) of the canvas as the origin of coordinates, with the X axis extending to the right and the Y axis extending downward. A user performs a signing operation using a pencil tool by first generating a canvas as a container and then generating drawing objects based on the canvas container. When the pencil writing operation is carried out, the drawing object uses a self line method to connect the coordinates to which the pencil moves, and when the line is drawn, the information such as the width, the color and the like of the line is set according to the information such as the width, the color and the like of the pencil selected by a user. And drawing and simultaneously recording an x-axis maximum value time coordinate, an x-axis minimum value time coordinate, a y-axis maximum value time coordinate and a y-axis minimum value time coordinate respectively, and calculating position information by using four point coordinates. And after the drawing is finished, converting the content of the canvas container into an image by using a canvas element picture conversion method. After determining the image attribute information of the image according to the target signature image, the front-end service integrates the format of the target signature image, the image attribute information (image length and width information) and the position information into xml format information conforming to the OFD standard, and finally uniformly packaging and storing the integrated format information of the integrated xml format and the target signature image into a target OFD document.
According to the technical scheme, the original writing style of the signature can be reserved through the imaging processing of the OFD document signature, and the problem that the handwritten font cannot be correctly identified and cannot be restored is solved.
