Responsible Changed From-To: freebsd-bugs->sos Over to maintainer. State Changed From-To: open->suspended The code was not mean to work with charset more than 8 bit wide. I may look into this eventually, a new libvgl project is on the horizon. State Changed From-To: suspended->closed If interrest arises again I'll look at it, for now this is simply not supported. |
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 * 0002000
