bool FillDrawPixelInfo ( DrawPixelInfo n,
int  left,
int  top,
int  width,
int  height 
)

Set up a clipping area for only drawing into a certain area.

To do this, Fill a DrawPixelInfo object with the supplied relative rectangle, backup the original (calling) _cur_dpi and assign the just returned DrawPixelInfo _cur_dpi. When you are done, give restore _cur_dpi's original value

Parameters:
*n the DrawPixelInfo that will be the clipping rectangle box allowed for drawing
left,top,width,height the relative coordinates of the clipping rectangle relative to the current _cur_dpi. This will most likely be the offset from the calling window coordinates
Returns:
return false if the requested rectangle is not possible with the current dpi pointer. Only continue of the return value is true, or you'll get some nasty results

Dimension GetStringBoundingBox ( const char *  str,
FontSize  start_fontsize 
)

Return the string dimension in pixels.

The height and width are returned in a single Dimension value. TINYFONT, BIGFONT modifiers are only supported as the first character of the string. The returned dimensions are therefore a rough estimation correct for all the current strings but not every possible combination

Parameters:
str string to calculate pixel-width
start_fontsize Fontsize to start the text with
Returns:
string width and height in pixels
