这可以通过以下方式轻松实现超链接图像类米斯梅利提出:
from reportlab.platypus import Image
class 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, x, y, _sW)
