Adapted build.xml to wims.(GK. Debian build)
15/6/2009
Corrected vertical y-axis text
Added param <param name="decimals" value="2">
This is the precision of reply_answer send to WIMS.
Usefull in large constructions...to limit query string and avoid trouble with server settings.
To be used independant of :
<param name="editdigits" value="2">
<param name="displaydigits" value="2">
<param name="angledigits" value="3">

Corrected language settings [param "language"]
Added reading of freehand drawing. [a string of x/y points]
Added applet params for grid & axis.
Added applet params for x-axis/y-axis text.
Added applet param for y-axis text orientation.
Added applet param for background image [animated gif, jpeg , png etc] http://localhost/test.gif
example:
<applet id="CaR" codebase="build" archive="zirkel.jar" code="rene.zirkel.ZirkelApplet.class" WIDTH="400" HEIGHT="400" ALIGN="CENTER" MAYSCRIPT>
<!-- <param name="file" value="http://localhost/1.zir"> -->
<!-- <param name="background_image" value="http://localhost/test.jpg"> -->
<param name="language" value="fr">
<!-- if axes/grid is activated -->
<param name="x_axis_text" value="my x-axis"><!-- default "x-axis" ; unicodesymbols allowed (if OS permits) → ⇔ -->
<param name="y_axis_text" value="my y-axis"><!-- default "y-axis" -->
<param name="y_axis_text_vertical" value="true"><!-- default "false" -->
<!-- some more params ;there are many more defined -->
<param name="nomousezoom" value="true">
<param name="minfontsize" value="14">
<param name="smallicons" value="what_ever"> <!-- size 32 ; remove param-tag for lager icons size 64 -->
<param name="grid" value="what_ever"> <!-- if grid param-tag is present, show grid ;value is non-important -->
<param name="snap" value="left"> <!-- if grid is present, snap to grid [left side oriented] -->
<param name="editdigits" value="2">
<param name="displaydigits" value="2">
<param name="angledigits" value="3">
<param name="color" value="255,255,255">
<param name="tools" value="line point area angle circle segment function ray">
<param name="options" value="back grid delete mouse">
<param name="style" value="full">
No java
</applet>

Added GetAllObjects();
function ReadApplet_II(){
<!-- this function retreives all construction details -->
<!-- excluded objects with name prefix \"my_\" -->
var data=document.getElementById(\"CaR\").getAllObjects().split(',');
var cnt=0;var reply=new Array();
for(var p=0;p<data.length;p++){
reply[cnt]=data[p].toString();
cnt++;
}
alert(\"the reply is:\n\"+reply);
}

Added "ray" , "function" , "intersection_point" , "point_on" to the detectable objects.
Remark: I've not yet found a "zirkel way" to change from degrees to radians.
E.g. a function sin(x) will use x in degrees.

Adding Zirkel to SVN.
[from 1.html]
The next drawing details can be retreived.
All objects must be named correctly by the student.
Multiple Objects of the same type but non-requested name will be ignored.
If an object/name combination is not present, the student will receive an browser alert message.
The implemented objects are [for now] :
* point , send as "point=point_name:x=x_value:y=y_value \n"
* line , y=slope*x+contant is send as "line=line_name:slope=a_number:constant=a_number:affine \n"
* if the line is vertical is will be send as "line=line_name:x=a_number:vertical \n"
* if the line is horizontal is will be send as "line=line_name:y=a_number:horizontal \n"
* segment , send as "segment=segment_name:x=a_number:y=a_number:x=a_number:y=a_number: length=a_number \n"
* fixedcircle , send as "fixedcircle=fixed_circle_name:x=a_number:y=a_number:r=a_number \n"
* circle , send as "circle=circle_name:x=a_number:y=a_number:r=a_number \n"
* angle , send as "angle=angle_name:value=a_number \n" [degrees or radians depending on appletparam]
* area , send as "area=area_name:x=a_number:y=a_number..... :area=a_number \n"
* function [no details ,yet]
Other objects -see zirkel/zirkel/rene/zirkel/objects/*java - could be implemented, if needed.
No extra applet params were defined. [not yet needed]
The applets public_function to communicate with javascript getDrawing("object","name_of_object");
or with multiple occurances of an object:getDrawing("object","name1,name2,name3,name4,...");
_________________________________________________________________
This example javascript code could be used to produce a working WIMS exercise.
function ReadApplet(){
<!-- this array should be produced using WIMS variables... -->;
var list_of_objects=["point,p1,p2,p3","line,l1,l2","function","area,poly1","angle,a1","circle","fixedcircle","segment"];
var count=0;var reply=new Array();var data;var tmp;
for(var p=0;p<list_of_objects.length;p++){
tmp=list_of_objects[p].split(',');
if(tmp[0].length>0){
for(var s=1;s<tmp.length;s++){
data=document.applets[0].getDrawing(tmp[0],tmp[s]);
if(data.indexOf("error")!=-1){
alert("Your answer will not be send...\nthe next object could not be detected in your drawing...\n\n:"+data); return;
}
else
{
reply[count]=data;
count++;
}
}
}
}
}
Note: all this is not yet used is a wims-module.
If needed -for example in OEF anstype? - everything can be adapted !
