Embodiment one:
referring to fig. 1, a custom signature generation method includes the following steps:
s1: receiving a signature picture uploaded by a user; preferably, referring to fig. 2, the signature picture uploaded by the user is obtained after the user photographs or scans blank paper covered with the signature.
Specifically, when the method is used, the enterprise user covers the signature on blank paper (A4 paper) and then converts the covered signature into a picture file in a photographing or scanning mode.
S2: acquiring the sampling interval and the sampling initial value of pixels in the signature picture;
s3: reading the RGB value of each pixel in the signature picture;
s4: processing the RGB value of each pixel according to the sampling interval, the sampling starting value and the preset transparentization cutting threshold value, and reserving the main tone color in the signature picture to obtain the transparentization picture, wherein the method specifically comprises the following steps of:
discarding the pixel when the R value, the G value and the B value in the RGB value of the pixel are all larger than the sampling start value;
presetting a Rtotal value, a Gtotal value and a B total value, wherein the Rtotal value, the Gtotal value and the B total value are equal;
when R value > max (G, B) +sampling interval in RGB value of pixel, adding 1 to R summation value;
when the G value in the RGB value of the pixel is more than max (R, B) +sampling interval, the G sum value is added with 1;
when the B value in the RGB value of the pixel is larger than max (R, G) +sampling interval, the sum value of B is added with 1;
wherein max is the maximum value calculation;
respectively calculating the sum of R sum value, G sum value and B sum value in all pixels;
and defining the color corresponding to the maximum value in the sum of the Rtotal value, the Gtotal value and the Btotal value as the dominant hue color so as to obtain the transparent picture.
Specifically, when background transparentization is carried out on a signature picture, parameters involved in the method include sampling interval, sampling start value, transparentization cutting threshold value and the like. Firstly, acquiring a sampling interval, a sampling starting value and a transparency cutting threshold value in a signature picture, and then reading RGB values of each pixel for comparison analysis, wherein the analysis method comprises the following two steps:
first, RGB color-homogenizing treatment mode: when the R value, the G value and the B value in the RGB value of the pixel are all larger than the sampling initial value, namely the pixel is light, the pixel is discarded at the moment, and the transparency processing is directly carried out.
Second, RGB non-uniform color processing mode:
first, the Rtotal value, the Gtotal value and the Btotal value are preset, and the Rtotal value, the Gtotal value and the Btotal value are equal, for example, the Rtotal value, the Gtotal value and the Btotal value are all set to 0.
When R value is greater than max (G, B) +sampling interval in RGB value of pixel, R value is added with 1;
when the G value in the RGB value of the pixel is larger than max (R, B) +sampling interval, the G value is added with 1;
when the B value in the RGB value of the pixel is larger than max (R, G) +sampling interval, adding 1 to the B value;
respectively calculating the sum of R sum value, G sum value and B sum value in all pixels;
and defining the color corresponding to the maximum value in the sum of the Rtotal value, the Gtotal value and the Btotal value as the dominant hue color so as to obtain the transparent picture. The method comprises the steps of defining the color corresponding to the maximum color value in each pixel as the dominant color of the pixel in a circulating way, and then confirming that the maximum value of the dominant color sum value of all pixels is the dominant hue color of the signature picture.
S5: and cutting off the transparent pixels at the edge in the transparent picture to obtain a signature. The method specifically comprises the following steps:
and reading the uppermost, lowermost, leftmost and rightmost pixels in the replaced transparent picture, determining coordinates of the four pixels in the transparent picture, and storing all pixel values in the four coordinates to obtain the signature. Fig. 3 shows a signature obtained after the transparentization process.
Specifically, the method finally cuts off the transparent pixels at the edges of the picture. And during processing, the color values of the uppermost, the lower, the left and the right sides of the picture are read, the coordinates of the four edges of the picture are determined, the RGB values in the coordinates are stored, the processed picture is generated, the signature is obtained, and the stored signature is output.
The method transparencies the background color of the signature picture. Because the signature pictures obtained by photographing by the user have factors such as light, the uploaded signature pictures have poor effect, and therefore the method needs to process the signature pictures, namely, analyze pixels one by one, including sampling of the pixels, definition of pigment threshold values and the like.
After receiving the signature picture, the method carries out background transparent processing on the signature picture and saves the signature picture into the signature of the enterprise, so that the electronic contract can be electronically signed. According to the method, each pixel of the picture is analyzed and processed, so that the transparency processing of the signature picture uploaded by a user is realized, and the personalized customization of the electronic signature is realized.
Preferably, after the obtaining of the transparent picture, the method further comprises:
gray processing is carried out on the main tone color of the pixel in the transparent picture;
and replacing the dominant hue color of the pixels in the transparent picture with the signature color set by the user.
In particular, the method may also replace the color of the signature with a user-set color, for example, the color of the signature may be modified to blue. In the replacing process, gray processing is firstly carried out on the main color, and then the main color of the pixels in the transparent picture is replaced according to the signature color (such as blue) set by a user, so that the personalized customizing function of the signature color is realized.
The method has wide application scenes, and is widely applied to scenes in which some subscribers have special demands on signatures, such as triangle signatures or other irregular signatures. However, the conventional electronic signing system can only generate a plurality of fixed signatures such as circles, ellipses and the like, and cannot generate irregular signatures. At this time, the user can seal on blank A4 paper in an off-line manner, take a picture or scan a signature picture and upload the picture, so that the uploaded signature can be subjected to transparency processing, and then the electronic contract is signed by using the signature obtained after the processing.
Embodiment two:
a computer tool comprises the custom signature generation method.
Specifically, the code of the method can be packaged into an SDK tool class interface, and the SDK tool class interface is provided for any system needing a signature transparency processing function. When the system is used, the transparency processing interface can be directly called by introducing the computer tool, the transparency processing of the signature is completed, the effects of one-time development and multiple multiplexing of multiple systems are realized, the system development time and the labor input cost are saved, and the development efficiency of other systems is greatly improved.
