This module provides some functions to render simple graphical objects like filled rectangles and lines as HTML elements.
# File lib/taskjuggler/reports/HTMLGraphics.rb, line 70 def arrowHeadToHTML(x, y) XMLElement.new('div', 'class' => 'tj_arrow_head', 'style' => "left:#{x.to_i - 5}px; " + "top:#{y.to_i - 5}px;") end
# File lib/taskjuggler/reports/HTMLGraphics.rb, line 59 def diamondToHTML(x, y) html = [] html << XMLElement.new('div', 'class' => 'tj_diamond_top', 'style' => "left:#{x.to_i - 6}px; " + "top:#{y.to_i - 7}px;") html << XMLElement.new('div', 'class' => 'tj_diamond_bottom', 'style' => "left:#{x.to_i - 6}px; " + "top:#{y.to_i}px;") html end
# File lib/taskjuggler/reports/HTMLGraphics.rb, line 53 def jagToHTML(x, y) XMLElement.new('div', 'class' => 'tj_gantt_jag', 'style' => "left:#{x.to_i - 5}px; " + "top:#{y.to_i}px;") end
Render a line as HTML element. We use ‘div’s with a single pixel width or height for this purpose. As a consequence of this, we can only generate horizontal or vertical lines. Diagonal lines are not supported. xs and ys are the start coordinates, xe and ye are the end coordinates. category determines the color.
# File lib/taskjuggler/reports/HTMLGraphics.rb, line 23 def lineToHTML(xs, ys, xe, ye, category) xs = xs.to_i ys = ys.to_i xe = xe.to_i ye = ye.to_i if ys == ye # Horizontal line xs, xe = xe, xs if xe < xs style = "left:#{xs}px; top:#{ys}px; " + "width:#{xe - xs + 1}px; height:1px;" elsif xs == xe # Vertical line ys, ye = ye, ys if ye < ys style = "left:#{xs}px; top:#{ys}px; " + "width:1px; height:#{ye - ys + 1}px;" else raise "Can't draw diagonal line #{xs}/#{ys} to #{xe}/#{ye}!" end XMLElement.new('div', 'class' => category, 'style' => style) end
Draw a filled rectable at position x and y with the dimension w and h into another HTML element. The color is determined by the class category.
# File lib/taskjuggler/reports/HTMLGraphics.rb, line 47 def rectToHTML(x, y, w, h, category) style = "left:#{x.to_i}px; top:#{y.to_i}px; " + "width:#{w.to_i}px; height:#{h.to_i}px;" XMLElement.new('div', 'class' => category, 'style' => style) end
