drawpixmaptext

Im working on a Gui library and i did not want to use any graphics contexts what so ever for making skins, i have been using pixmaps for everything. I did manage to just write a function to draw imagefonts to a pixmap, this is not a realtime function i just needed it for prerendered text to slap as a panel pixmap.

So far this is what i got. Still needs some improvement, let me know if there are any problems or tips you can give me.

Function drawpixmaptext(text$,pix:TPixmap,x,y,font:TImageFont,red=255,green=255,blue=255)
Local newx
Local theight			
			
		
		
		theight = font.Height()	
		Print theight	
		For i = 0 To text.length-1

			tempText$ = Mid(text, i+1, 1)
			asciiVal = Asc(tempText)
			n=font.CharToGlyph( asciiVal )
			If n<0 Continue
			
			glyph:TImageGlyph = font.LoadGlyph(n)
			image:TImage=glyph._image
			Print "Draw "+Chr(asciiVal)
			If image <> Null
			tempix:TPixmap = LockImage(image)
			UnlockImage(glyph._image)
			
			If tempix

				
			
					
					For yy = 0 To tempix.height-1
						For xx = 0 To tempix.width-1
							If newx+x+xx < pix.width And y+yy < pix.height Then
							
							alpha# = RGBA_alpha(ReadPixel(tempix,xx,yy))
							alphan# = Float(alpha#/255.0)
							anti# = 1.0-alphan#
							ured = RGBA_Red(ReadPixel(tempix,xx,yy))
							ugrn = RGBA_Green(ReadPixel(tempix,xx,yy))
							ublu = RGBA_Blue(ReadPixel(tempix,xx,yy))
							
							newred = ((RGBA_Red(ReadPixel(pix,newx+x+xx,y+yy))*anti#)+(ured*alphan#))
							newgrn = ((RGBA_Green(ReadPixel(pix,newx+x+xx,y+yy))*anti#)+(ugrn*alphan#))
							newblu = ((RGBA_Blue(ReadPixel(pix,newx+x+xx,y+yy))*anti#)+(ublu*alphan#))
		

							If newred > 255 Then newred = 255
							If newgrn > 255 Then newgrn = 255
							If newblu > 255 Then newblu = 255
														
							WritePixel(pix,newx+x+xx,(theight-tempix.height)+y+yy,ToRGBA(newred,newgrn,newblu,255))

							EndIf
						Next
					Next
					
			EndIf
			EndIf
			newx = 	newx + tempix.width
