Draw Text
Version: 1.0


Introduction
An Little addon for any bitmap that allows you to draw wrapped text or formatted text it automatically wraps to the next line if the text is too long to fit on the line. Also adds features (for formatted text) like color changing, italics, bold, new line, and tabbing.


Screenshots
I'll post them if requested


Script
add this in a new script above main

Code:
#C[RRBBGG] Changes the Color (RR,BB,GG)
      #C[N] Changes to color back to normal
      #I[] Changes the font to Italics
      #B[] Changes the font to Bold
      #T[] A Tab
      #N[] New Line
#==============================================================================
# ** Bitmap
#------------------------------------------------------------------------------
#  Additions add a draw wrap text method which draws word wrapped text
#  Text Automattically goes to the next line if the text can not fit on the line
#==============================================================================

Instructions

to call this all you have to do is
self.contents.draw_formatted_text(x,y,width, height, text)
or
self.contents.draw_wrap_text(x,y,width,height,text)

you may also call get_wrap_size, and get_formatted size to get the rectangle the text is drawn on (corresponds to method text_size)


where offset_x is the x coordinate to start drawing text and offset_y is the y coordinate to start drawing, text is the text to draw

If you use C[RRGGBB] where RR GG and BB are hexadecimal color values inside the text then the color will change to that color. To change it back just put C[N]. If you want bold text then type B[] for Italics use I[]. If you want a newline just put N[] and for tab (4 spaces) use T[] you can easily change these flags by modifing the Regexp used in these lines

Code:
text.gsub!(/[Cc]\[((([A-F]|[a-f]|[0-9])+)|N)\]/) {" \001[#{$1}] "}
        text.gsub!(/[Bb]\[\]/) {" \002 "}
        text.gsub!(/[Ii]\[\]/) {" \003 "}
        text.gsub!(/[Tt]\[\]/) {" \004 "}
        text.gsub!(/[Nn]\[\]/) {" \005 "}
