Hi,
in the process of preparing our transition to python 3
I encountered a problem with bitmap, which could
be boiled down to:
#------------------------------
from pyx import *
img_string = "\77\77\77\33\177\177\177\44\277\277\277\55\377\0\0\66" + \
"\0\377\0\77\0\01\37\0"
image_rgb = bitmap.image(3, 2, "RGBA", img_string)
bitmap_rgb = bitmap.bitmap(0, 0, image_rgb, height=0.8)
c = canvas.canvas()
c.insert(bitmap_rgb)
c.writePDFfile("minimal")
#------------------
This code runs fine under python 2.7 (and pyx 0.12.1)
while under python 3.4 (and pyx 0.13) I get:
lib/python3.4/site-packages/pyx/bitmap.py", line 375, in imagedata
data = zlib.compress(data.tobytes(), self.flatecompresslevel)
TypeError: 'str' does not support the buffer interface
Can you reproduce this (in 0.13.0 and in trunk)?
(I also manually tried to apply the change
http://sourceforge.net/p/pyx/code/3598/
but this did not help, or I did not apply it correctly).
Nothing urgent, as we won't be moving to python 3 that soon,
but still a fix or work-around would be nice ...
Many thanks, best,
Arnd
