Bug in TLine drawing when lines are too short

Hi Otto,

See my explanation about the precision issue in this case:

X length of l4 = 717900-717886 = 14
Number of pixels along X = 1200
X length of the axis = 1000000
l4 length in pixels = 14.*(1200./1000000.) = 0.0168000 pixels ... 

so seeing nothing for l4 is normal in pixel mode. This line length is 1/100 pixel long…

The problem was that l4 was drawn as an horizontal line on the png file when the macro was ran in batch.

It was clearly a bug in TASIMage.cxx. It is now fixed in the master.


Great ! thanks for the fix !
