SPL Module Reference: epfb

SPL EPFB Module

This Module provides hardware accelerated graphics on EP9315 processors.
It is tailored for the NetBSD/evbarm architecture.
If compiling fails, make sure that the file epio.h is in include path.

builtin epfb_cursor_moveto(x,y);
builtin epfb_cursor_position(x,y);

builtin epfb_pixelset(x,y,col);

Set the colour of a single pixel on screen.

builtin epfb_linedraw(startx,starty,stopx,stopy,col);

Draw a line from (x1/y1) to (x2/y2) on screen.

builtin epfb_blockfill(x,y,width,height,col);

Rectangular blockfill from (x/y) with given width and height.

builtin epfb_drawtext(x,y,text,col);

Renders text at (x,y) with given colour.

builtin epfb_cursor_setup(width,height,col1,col2,blink1,blink2,blinkrate);

Setup Hardware Cursor.
The cursor must be enabled with [epfb_cursor_enable] as well.
The cursor position can be specified with [epfb_cursor_moveto].

builtin epfb_cursor_pixel(x,y,value);

Set pixel value for hardware cursor.
The value must be in the range of 0 to 3 (00 to 11).
0 means transparent, 1 means invert of video stream,
2 means (blink) colour 1, 3 means (blink) colour 2.

builtin epfb_cursor_enable(enable);

Enable or disable hardware cursor.
1 is enable, 0 is disable.

builtin epfb_cursor_moveto(x,y);

Set Hardware Cursor Position on screen.

builtin epfb_cursor_position(x,y);

Get Hardware Cursor Position on screen.
