color_show and ImageGrid don't render properly in Spyder or Ipython QTconsole

[lwasser]

Hi All,
this is an interesting bug. When i attempt to render a grid using ImageGrid, i get space where the grid should render in the console BUT no grid. Or i get a series of lines - one line for each cell with the appropriate assigned colors, however no actual cells. this issue is a bit baffling because it works perfectly in notebook. doesn't it all just use the ipython renderer?

for example, this code doesn't render:
from ipythonblocks import ImageGrid
grid = ImageGrid(5, 3)
grid.show()

This code renders lines:
row = ImageGrid(8, 1)
row[0, 0] = (0, 0, 0) # no color => black
row[1, 0] = (255, 255, 255) # all colors => white
row[2, 0] = (255, 0, 0) # all red
row[3, 0] = (0, 255, 0) # all green
row[4, 0] = (0, 0, 255) # all blue
row[5, 0] = (255, 255, 0) # red and green
row[6, 0] = (255, 0, 255) # red and blue
row[7, 0] = (0, 255, 255) # green and blue
row.show()

Everything works perfectly in notebook so i understand if this is a notebook focused package!
thank you

ipythonblocks is definitely browser oriented--the tables are rendered as HTML tables and include CSS styles.The Notebook is the only "supported" platform for ipythonblocks. But if anyone familiar with Spyder or the QT console would like the comment, the info would be welcome.

Is there a "save as PNG" option?

If you install from GitHub, yes. See the save_image function. I apparently forgot to make a release with that included.

Do you have time to make a release that include save_image? Or can we
ask @r-gaia-cs to do it?
Thanks,

Should be able to make one today.
