>Environment:
Current libvgl implementation (4.1-STABLE)
>Description:
The current version of libvgl in 4.1-STABLE does not draw fonts wider than
8 pixels correctly. The code in VGLBitmapPutChar performs some bit
operations that work only with fonts up to 8 pixels in width.
>How-To-Repeat:
This code should draw a full bar near the top left corner of the screen,
but it only draws a pattern. Only the right halves of each character get
drawn, due to the bit handling in VGLBitmapPutChar.
#include <machine/console.h>
#include <vgl.h>
int main (int argc, char *argv[])
{
VGLInit (SW_CG640x480);
VGLTextSetFontFile ("blocks.vgl");
VGLBitmapString (VGLDisplay, 64, 64, "TEST STRING",
7, 0, 1, VGL_DIR_RIGHT);
sleep (5);
VGLEnd ();
}
The blocks.vgl is 8194 bytes long, and is made up like this:
0000000 1010 ffff ffff ffff ffff ffff ffff ffff
0000010 ffff ffff ffff ffff ffff ffff ffff ffff
