195 | @ Canvasdraw can be used to paint a html5 bitmap image<br>by generating a tailor-made javascript include file: providing only the js-functionality needed to perform the job.<br>thus ensuring a minimal strain on the client browser <br>(unlike some popular ''canvas-do-it-all`` libraries, who have proven to be not suitable for low-end computers found in schools...) |

17351 | bpr | 5202 | @ note: when zooming / panning after a drawing, the drawing will NOT be zoomed / panned...this is a "design" flaw and not a feature <br>To avoid trouble do not use zooming / panning together width userdraw.!<br>use command <a href="#multidraw">multidraw</a> is this is a problem for you... |
14247 | bpr | 5203 | @ note: the default replyformat for ''userdraw input(s),color`` used format x1;y1;text1 \n x2;y2;test2 \n x_n;y_n;text_n (e.g. it is not a comma separated array...use ''direct exec`` to test) |
17351 | bpr | 5204 | @ note: a special case is ''userdraw image,boguscolor``. Images (bitmap or svg or div) present in the exercise page and the img/svg/div-tag with an unique 'id' and <code>onclick='javascript:place_image_on_canvas(this.id)'</code> can be placed onto the canvas.<br>The ''id`` and (x;y) coordinates will be returned using read_canvas();<br> native MathML, MathJax or KaTeX typesetting may be included in div's.(experiments; wims_modules svn version only!) |
