Hello
In this function
def get4(srcpages):
scale = 0.5
srcpages = PageMerge() + srcpages
x_increment, y_increment = (scale * i for i in srcpages.xobj_box[2:])
for i, page in enumerate(srcpages):
page.scale(scale)
page.x = x_increment if i & 1 else 0
page.y = 0 if i & 2 else y_increment
return srcpages.render()
found here
https://www.blog.pythonlibrary.org/2018/06/06/creating-and-manipulating-pdfs-with-pdfrw/
I do not understand this line:
x_increment, y_increment = (scale * i for i in srcpages.xobj_box[2:])
(scale * i for i in srcpages.xobj_box[2:]) is a generator, a single
object, it should not be possible to unpack it into 2 variables.
x, y = 1 generates an error
x, y = (i for i in range(10)) too
but not
x_increment, y_increment = (scale * i for i in srcpages.xobj_box[2:])
why ?
