New (minor) release of Mamba 2

[Serge Beucher]

Hi,

A new and minor release of Mamba is available (Mamba 2.0.1). It aims at correcting a bug in TkInter (not in Mamba) with the askcolor function which returns float values instead of integer ones (error in the Python division). This bug made Mamba crash when using the superpose display function if you tried to change the display colors.

The Windows installers of this new release are also available from the Mamba Web page.

Sincerely,

Serge Beucher

Hi, I still have this problem with your 2.0.1 release, below is the Traceback.

I use Python 3.5 64 bit on Windows, the version string is:
Python 3.5.1 (v3.5.1:37a07cee5969, Dec 6 2015, 01:54:25) [MSC v.1900 64 bit (AMD64)] on win32

I built mamba-image from the github source with the VS 14 2015 Win64 compiler without errors. It is the compiler used to build Python 3.5 (see https://wiki.python.org/moin/WindowsCompilers). The resulting Mamba Image-2.0.1.win-amd64-py3.5.exe installs without any problems.

Hi,

After reviewing the code it seems there are still some divisions not upgraded to the python 3 format (/ instead of // which produce float where integer are expected). It is likely this is what provoke your problem. Lines 277, 278 and 279 in file display2D.py are certainly the culprit.

Tell us if that correct your problem.

Nicolas.

Hi,

Just a precision: do not change the division for the zoom variable (line 279) which is a float. Other problems are likely to occur for other functions. We are checking this integer division issue and will post corrections in the github source as soon as possible.
