Summary	0001520: granularity of the STF slider is wrong
Description	Trying to use the stf slider to adjust a transfer function to an mr data set does not work. The smallest step that I was able to produce jumped half of the dynamic range of the visible transfer function. The two images show the smallest slide that I was able to accomplish
Tags	No tags attached.

finetjul 2011-11-03 08:04 administrator ~0003240	What do you think granularity should be ? Shall we have a popup that slides down to control granularity ?

kikinis 2011-11-03 09:54 developer ~0003243	I think that it should be approximately 100 steps for the width of the visible transfer function. Horizontal scaling should be done with the existing sliders below the transfer function.

finetjul 2011-11-08 19:08 administrator ~0003284	Fixed in r18639. The granularity was already set to 1% of the total width of the transfer function. However, the change was done only when a new preset was selected, not when the transfer functions were manually edited.
