A space character is the # same displacement, but no glyph is rendered. # text fixed_space (value) # is a portion of the width of the square. # text fixed_space 1.00 # is square; as much width as height. # Values can be less than or greater than 1.00 # text variable (type) # each glyph is placed according to its own width, # plus a settable gap and space. # text vari_space (value) # is the width of a single space character in # variable text as a portion of the square. # Since the font is rendered according to the # width of each visible glyph, it is necessary # to designate a value for the space character, # which has no measurable width. # text vari_space 0.67 # designates 67% of the width of the square. # text vari_space -1 # A value of -1 sets the variable space width # to be equal to the widest character in the font. # text vari_gap (value) # is a portion of the square used as the gap # between the glyphs (in a word). # text vari_gap 0.20 # is 20% of the square. # This gap is used to space all of the characters # in a text string, including the space character. # The actual gap between words rendered from a # single space character is # vari_gap + vari_space + vari_gap # the last visible character of a word, followed by # its vari_gap, plus the width of a space character # (vari_space) followed by its vari_gap. # text line_space (value) # is a portion of the square (height) that sets # the space between lines of a multi-line text form. # text font_name (name) # designates the name of a font in the # ./LaserBoy/ild/fonts/ # directory (without the .ild extension). # text font_name square # is included for demonstration of glyph space. # Note: since every glyph of # text font_name square # takes up all of the space, height and width of # the square, using it in a "variable" text form will # result in every visible glyph having the same width # (all there is to have). # Each glyph is placed into real coordinate space # (3D double float) to form a line or a page of text. # This real space is then scaled to fit # signed short integer space. # text to_space (value) # is the portion of all short int space to fill, # aka a LaserBoy frame. # text to_space 1.00 # fills the whole frame between at least two edges. # Any value above 1.00 is considered 1.00. # If a glyph is made of more than one lit segment, # the lit segments are bonded together with lit black. # When LaserBoy looks for lit segments to treat as # individual elements in a vector image, it sees # whole glyphs (not their separate strokes). # By default, all fonts that come with LaserBoy # have bonded glyphs # text bond_word (0 or 1) # With this setting LaserBoy will render text # with bonded words, so that individual words # are seen as whole objects. # text bond_word 1 # enables word bonding. # text bond_word 0 # disables word bonding. # text bond_line (0 or 1) # With this setting LaserBoy will render text # with bonded lines, so that individual lines # are seen as whole objects. # text bond_line 1 # enables line bonding. # text bond_line 0 # disables line bonding. # In the app, menu h, option b or B converts # lit black to blank for ild file compatibility. # text still_frames (value) # is the introduction to the animated # LaserBoy text forms. It is an integer # number of frames to be added to the # LaserBoy frame set that are all the # same frame as described in a single # frame text form. This is for setting # and holding a single frame of text # for multiple frames of time. # text view_span (value) # is the width or height of the visible text # window in an animated text form. # This only defines one dimension as the other # comes from the rendered size of the text. # text view_span 8.00 # shows 8 whole squares. # text move_per_frame (value) # With the animated text forms each frame # represents a change in text position of a # portion of the square as it appears after # being clipped by the visible text window. # text move_per_frame 0.15 # moves the text by 15% of the square. # With the marquee form, the visible window # has a height of however many lines are in # the text, including blank lines between the # first and last visible line. # The width is set by view_span. # With the scroll form, the visible window # has a width of the widest line of text. # The height is set by view_span. # The scroll starwars text forms are not effected # by the value of view_span. The visible window # is set to twice as high as it is wide. # All available settings and their default values. # None of them need to be set to render text. #text fixed_space 0.70 #text line_space 1.10 #text vari_space 1.00 #text vari_gap 0.20 #text to_space 0.85 #text font_name laserellipse #text color_rgb 255 255 255 #text bond_word 0 #text bond_line 0 #text still_frames 1 #text move_per_frame 0.15 #text view_span 8.00 # All available forms # (single frame forms) # text fixed line # text fixed left # text fixed right # text fixed center # text fixed just # text fixed at # text variable line # text variable left # text variable right # text variable center # text variable just # text variable at # (animated frames forms) # text fixed marquee # text fixed scroll left # text fixed scroll right # text fixed scroll center # text fixed scroll just # text fixed scroll starwars # text variable marquee # text variable scroll left # text variable scroll right # text variable scroll center # text variable scroll just # text variable scroll starwars # <<__TEXT_END__>> This tag right here needs to be the # last line of any multi line text form # or else LB will render everything to # the end of the file. # The comment mark '#' has no meaning within text # that is headed for rendering.

It is a single stroke font {this one} made in CAD, saved as DXF and converted to ild vector format in LaserBoy. It is made of nothing but straight lines and elliptical arcs. A derivative of this font, called square, is also included as a demonstration of the font space square; a concept used as a measure of things rendered in LaserBoy text formats. <<__TEXT_END__>> #---------------------------------------------------- text vari_space 0.50 text vari_gap 0.16 text font_name wide_vector text color_rgb 200 100 255 text view_span 10.00 text to_space 0.67 text move_per_frame 0.08 text variable scroll right It is possible to control several aspects of style within the contents of a LaserBoy font rendering text file.

It is a period of civil war. Rebel spaceships, striking from a hidden base, have won their first victory against the evil Galactic Empire. During the battle, Rebel spies managed to steal secret plans to the Empire's ultimate weapon, the DEATH STAR, an armored space station with enough power to destroy an entire planet. Pursued by the Empire's sinister agents, Princess Leia races home aboard her starship, custodian of the stolen plans that can save her people and restore freedom to the galaxy..... <<__TEXT_END__>> #---------------------------------------------------- text line_space 1.40 text vari_space 0.30 text vari_gap 0.10 text font_name times_new_roman text color_rgb 255 80 200 text variable scroll starwars |||| #### |||| ## Be safe. ## |||| #### |||| ## Wear mask. ## |||| #### |||| #### |||| #### |||| #### |||| ~ laserboy.org ~ L a s e r B o y !!! . 2020 . * James Lehman * Extra Stimulus .
