Requirements:
This is the problem that comes up when you do a certificate. at that time, the demand is to be able to print the certificate online, the first operation is to print the HTML directly, and has been lined up (with the Jqprint plug-in) to print, in the printing encountered a compatibility problem, in addition, because the background image loading is slower than the text loading, the first load of text appears after the phenomenon of the picture, It is very unprofessional, then the use of the information into a picture, and then directly print the picture, no matter how to print, will not change, and can export pictures, the picture for more fine operation.
Code writing:
First of all, say the code First:

Note: In the code called to the previous article to obtain the size of the corresponding class, the purpose here is that for different works, may be horizontal or vertical picture, in order to ensure that the picture is not distorted, the picture is displayed in a fixed area,like here:
The default is a section of 660*660 area, first of all to determine whether to add a picture is a horizontal bar or vertical bar, if it is a horizontal bar, then the width is greater than the height, then set a large width of 660, corresponding to the proportion: 660/width = Required height/actual height, you can get the corresponding height value, And this height value is certainly less than 660, because it is a horizontal bar, so the width of the displacement is the corresponding displacement of the specified area, here is 600px, and the height of displacement, it should be added to the upper left corner of the image, the height of the background image of half minus the image of the current height of half; The height is greater than the width, then the height is set to 660, and so on, to get the corresponding displacement and size. To achieve the effect of what it looks like, let us briefly look at:(this is height greater than width)
(this is width greater than height)
