Zooming around a crowded schematic I wondered about all the text which was plotted yet can't be read (since it's too small); this also gives an idea on how sad is the performance of my workstation:PIn fact, in drawtxt there's already such a check, altough misformulated... A patch worth more than a thousand words: === modified file 'common/drawtxt.cpp' --- common/drawtxt.cpp 2012-05-03 18:37:56 +0000 +++ common/drawtxt.cpp 2012-05-22 13:25:48 +0000 @@ -347,7 +347,7 @@ /* if a text size is too small, the text cannot be drawn, and it is drawn as a single * graphic line */ - if( ABS( aSize.x )< 3 ) + if( aDC&& aDC->LogicalToDeviceYRel( ABS( aSize.y ) )< 8 ) { /* draw the text as a line always vertically centered */ wxPoint end( current_char_pos.x + dx, current_char_pos.y ); The check on the size is done in *user* units (mils for eeschema, whatever for the other programs). Legibility is determined by the zoom level (which is handled by the DC), so just ask it the effective size (8 is of course an arbitrarily determined value in pixels...). Exactly like the "Greek Text below # pixels" in Adobe reader. IMHO is better a rectangle instead of a line, but that's a personal preference thing...
This is a legacy code. if( aDC&& aDC->LogicalToDeviceYRel( ABS( aSize.y ) )< 8 ) is now better (although 5 pixels is still readable). However it was made to have a faster refresh screen in hight zoom values. Now this is less useful, a text can be always drawn regardeless its size in pixels (this is currently what happen). -- Jean-Pierre CHARRAS KiCad Developers team.
