<TITLE>something squirrelly with the PNG/PPM driver</TITLE>

<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I’ve been beating my head over what I thought was a bug introduced into the rendering routines of wxgrass, only to just find out that it is something introduced into the PNG display driver very recently—maybe on last Thursday or Friday.<BR>
<BR>
The easiest way to see what is happening is to display a legend or scale bar in the GUI. In both, white goes to black in the display. Both display fine in an xmon. <BR>
<BR>
If the scalebar background is set to transparent, it displays OK. But white goes to black. The same is true for legends of cell maps. White turns to black. For FP maps, the whole thing turns black and won’t even render properly in wxPython (locks it up, maybe because it is generating a PNG for this instead of a PPM). <BR>
<BR>
All is OK on my laptop, which I updated last Thursday or Wednesday, but the PNG/PPM display driver is broken on my office desktop, which I updated and recompiled last Friday afternoon.<BR>
