有没有办法在ReportLab中添加一个href / link到Platypus Image对象?我知道如何在段落中添加文本链接,但我似乎无法找到有关为图像添加链接的任何信息.最佳答案这可以通过missmely提出的HyperlinkedImage class轻松实现:
from reportlab.platypus import Imageclass HyperlinkedImage(Image,object): # The only variable I added to __init__() is hyperlink. I default it to None for the if statement I use later. def __init__(self,filename,hyperlink=None,wIDth=None,height=None,kind='direct',mask='auto',lazy=1): super(HyperlinkedImage,self).__init__(filename,wIDth,height,kind,mask,lazy) self.hyperlink = hyperlink def drawOn(self,canvas,x,y,_sW=0): if self.hyperlink: # If a hyperlink is given,create a canvas.linkURL() x1 = self.hAlignAdjust(x,_sW) # This is basically adjusting the x coordinate according to the alignment given to the flowable (RIGHT,left,CENTER) y1 = y x2 = x1 + self._wIDth y2 = y1 + self._height canvas.linkURL(url=self.hyperlink,rect=(x1,y1,x2,y2),thickness=0,relative=1) super(HyperlinkedImage,self).drawOn(canvas,_sW)
