Ft_Gpu_Hal_WaitCmdfifo_empty(phost);

You can set point size using POINT_SIZE command, set point color using COLOR_RGB and set location

using VERTEX2F. There is possibility to draw in very similar way round-cornered rectangles (RECTS

command), curvature of the corners can be adjusted using LINE_WIDTH command.

2.4 Lines drawing

In this example, the method for drawing lines in different locations is presented. You will see 8 crossed

lines which imitates street map. On this map will be text “Main s.”.

Figure 4. Lines drawing example

In the Figure 4. you can see effect of following code:

Ft_Gpu_CoCmd_Dlstart(phost);

Ft_App_WrCoCmd_Buffer(phost, CLEAR_COLOR_RGB(236,232,224)); //light gray

Ft_App_WrCoCmd_Buffer(phost, CLEAR(1,1,1));

Ft_App_WrCoCmd_Buffer(phost, COLOR_RGB(170,157,136));//medium gray

Ft_App_WrCoCmd_Buffer(phost, LINE_WIDTH(63));
