Hello David Zwarg,
it would be great, if the functionality of the renderers could be
expanded.
If it is a bug, the missing declaration for "symbol[key]" in line 560
in ArcXML.js should be added soon.
Moreover I don't understand these lines in ArcXML.js (lines 683-688):
for (var i=0, len=keys.length; i<len; i++) {
var key = keys[i];
if (symbol[key]) {
selem.setAttribute(key, renderer[key]);
}
}
"selem.setAttribute(key, symbol[key]);" makes more sense, doesn't it?
Generally I would be interested in full ArcXML support for all
further types of renderers (valueMapLabel, simpleLabel and valueMap).
What do you think, would it be possible to write all symbols and
attributes in arrays as you did with "fontStyleKeys" (line 27-30)?
Otherwise you always check the type of each attribute, but ArcIMS
makes no difference and you can only use attributes you have
mentioned in your code, for example:
if (typeof exact.symbol.width == "number") {
selem.setAttribute("width", exact.symbol.width);
}
I don't see any problem, if you allow the usage of every attribute
for every symbol, because you have to know ArcXML anyway if you work
with ArcIMS - you have to know which symbols or attributes can be
combined.
Unfortunately I'm not familiar with OpenLayers, so can you tell me
how I can contribute to OpenLayers?
Thank you for your help.
Best regards,
Christian Steger

Hello,
The ArcXML implementation is incomplete, yes. I wrote it to support
basic thematic mapping, and I can add other renderers as folks need
them. Although, it looks like you added a simple renderer below --
probably filing a patch would be the fastest way to get it in to
ArcXML.
It's definitely possibly to send ArcXML directly to ArcIMS, although
I would like to see more of the spec implemented in the format itself
first.
