Hi all,

I use the API glLineWidth() to change the width of line ,but why it doesn't effect?
Or OpenGL ES doesn't support the  glLineWidth()?

Re: glLineWidth()

In general, OpenGL ES supports lines with varying widths. However, there is nothing in the specification which warrants 
support for a minimum range, i.e. an implementation can support line widths from 1..1 and be compliant.

Any line width that isn't within the GL_ALIASED_LINE_WIDTH_RANGE (GL_LINE_SMOOTH disabled) or GL_SMOOTH_LINE_WIDTH_RANGE
 (GL_LINE_SMOOTH enabled) will either be clamped or ignored.
