Name : text_box Purpose : Writes a text message within a box in a graphics window. Description: This procedure writes a short text message within a box-shaped area in a graphics window. The message may be split at word boundaries into several lines, and the character size and orientation may be adjusted for the text to fit within the box. Useage: text_box,text,pos=pos,color=color,$ justify=justify,vert_space=vert_space Inputs TEXT ASCII text string containing the message. keywords pos 4 element vector specifying the box position and size pos[0],pos[1] specify the lower left corner coordinate pos[2],pos[3] specify the upper right corner coordinate data window normalized coordinates are use fg_color color of box and legend titles (default=0) bg_color background color. Setting BG_COLOR erases the area covered by the text box (filling it with color BG_COLOR) prior to writing the text. If both BG_COLOR and !p.color are zero then the background color is reset to 255 to gaurantee a readability. right if set, right justify text center if set, center the text vert_space vertical spacing of lines in units of character height (default = 1.5) author: Paul Ricchiazzi 7Jul93 Institute for Computational Earth System Science University of California, Santa Barbara
