Hi chiachen:
The font is English and shows right,but just looks very strange.It
looks like that some pixels of the letters are missing and the letters
are mixed with different colors
.And the backgroud color of the gtk widget is always pink (In normal
condition,I think the background should be white).
I have tried to change the parameters of the DirectFB by modifying
the directrc file, and I find that the reason is just because of the
pixelformat:
1 - If I set the pixelformat to RGB16,the display of font and widget
looks good, and the backgrond becomes normal.
2 - But if I set the pixelformat to RGB24 or other format,it looks
strange.Default format is LUT8,so it looks strangs as my description.
I think maybe it is because the hardware mode is RGB 16bit, so it
can only work in RGB16 pixelformat, and I don't know whether I
misunderstand it.Is there anyone can explain the reason to me ?Thanks!
