donating code to this project

[ScottPez]

Hi,

I am checking to see if anyone at this project would be interested if
we donated to this project what we are calling our FlexLayers
codebase. I can briefly describe what I had done to create this api.
Basically, I had ported a portion of the OpenLayers codebase (about
8-12 months ago) from Javascript to ActionScript 3. I had completed
WMS support, WMS-C support, and was close to completing WFS support
using ActionScript graphics as the renderer. I had also implemented a
few of their basic controls. We have only used this code for internal
purposes at The GeoVISTA Center at Penn State University. Please let
me know if anyone is interested in this donation.

Thanks,
Scott

Hi,

Thanks, We should be REALLY interested by your proposal.

How would you contribute your code ? Send us by mail, publish it on the download section ? Commit it on the Subversion ?

Also, are you motivated to contribute to the project in the future, in terms of code or ideas ?

Best regards,
Bouiaw

Hi Scott,
I would be more than happy to get the code of FlexLayers because we'd like to develop a proof of concept prototype for a web mapping application.
For information, we are developing only open source software (for example: www.mapfish.org).
Is it possible to obtain this code ?
Thanks in advance,
Cédric

Hi Bouiaw,

Sorry for the delay in getting back to you. I wanted to let you know
that I think we have decided to just post our code on code.google.com.
Then you should be able to download it from there. I am working to get
everything in order with the code and also get a demo together. I
should have these items done by the end of this week. I will let you
know when this is complete and they are available on code.google.com.

I should be interested in contributing further to this project. I am
not sure the depth of how much I can contribute. I think this depends
on our current projects. But we are still doing quite a bit of Flex/
Flash/ActionScript development. So I think it would be beneficial to
keep in touch and contribute further.

Thanks,
Scott

Hi Cédric,

I just posted a previous post on this thread that we will be posting
our code on code.google.com. I will also be posting a demo along with
the code for that demo. I should have this up by the end of this week.
I will let you know when this is complete and available for download.

Thanks,
Scott

Bouiaw,

The Google Code project which I promised is now available at:

http://code.google.com/p/flexlayers/

I have posted all of the code as well as links to two hosted demos.
The code for these demos is also available with the source code.
Please let me know if you have any questions.

Thanks,
Scott

Very impressive Scott !

I had a quick look to the code, this is a real AS3 OpenLayers !

There is a few dependencies to Flex that could be easily replaced by
AS3 ones (Canvas -> Sprite).

Even if we have started to write some code, with a different
architecture, I am in favor to use your codebase for OpenScales basis.
We must discuss this point with Aurelien and Romaric since it was not
expected ;-)

I will give you an update shortly.

[Bouiaw]

Hi Scott,

After discussing with other contributors, we are ok to create a
branche based on your code, in order to work on it to see we can base
OpenScales on it. Depending on the success of this step, we will
decide if we use it as the official codebase.

I have some questions :
- We would like to have no dependency on Flex, only on AS3 in order to
to keep OpenScales as small as possible (as we target also mobile). Do
you have in mind some problems that could prevent it ? We intend to
convert Canvas to Sprite, Image to Bitmap, etc.
- It is important to keep high flexibility, but as ActionScript is
more typed than Javascript, we would like to replace Object type by
explicit types. What is your advice about this ?
- In oder to make test easier, we would like to use Open Street Map
data source. Do you think that http://www.openstreetmap.org/openlayers/OpenStreetMap.js
could be ported easily in AS 3 ? Is there some tweak to know ?
- Are you interested to contribute to OpenScales if we use your
codebase ?

Thanks in advance for your help,
Bouiaw

Hi,

I have finished the first step of the import of flexlayers code into
openscales SVN.
To browse, use http://openscales.org/p/openscales/source/tree/HEAD/branches/flexlayers
To checkout, use http://openscales.org/svn/openscales/branches/flexlayers
To test last snapshot use http://openscales.org/openscales-flexlayers.swf

Changes I made :
- Fix compilation issues
- Update package name
- Fix close to 150 warnings about untyped variables, 600 remaining
warning to fix
- Create Flex Builder configuration & check that compile is ok
- Create Maven configuration & check that compile is ok

OpenScales-FlexLayers is automatically build by Hudson (http://
openscales.org/hudson/job/OpenScales-FlexLayers/)

Scott, I did not succeed to get images embeded into the SWF. Perhaps
they are lost in the SWC dependency step ... Do have an idea (compiler
parameter) to fix it ?

There is a still a lot of type warning, I will continue to fix them
tomorrow. If someone want to help me, he is welcomed ;-)

I have fixed mouse wheel bug an partially panning bug.

Remaining issues are in the bugtracker :
http://openscales.org/p/openscales/issues/search/?q=flexlayers&s=Search
Snapshot is automatically build after each commit :
http://openscales.org/openscales-flexlayers.swf

Thanks, Bouiaw. There are a couple of items I can probably already
contribute. For example, I think in another version of the code, I had
fixed the issues with broken tiles and the DragPan problems (which I
mention in the demos). I will look to try to find the fixes and then
commit these (if I am able to find them).

As far as your questions below:

I will take a look at the OpenStreetMap.js file and see if I think
there is anything to prevent the conversion to AS3.

It is my belief that you should be able to easily use pure AS3 classes
instead of the Flex components (substituting a Sprite for Canvas and
Bitmap for Image, etc.). I don't think there was anything Flex based
that was necessary.

Sorry about all of warnings for missing type definitions. I was under
a bit of a time crunch when I did this and didn't add these when I
converted from OpenLayers code.

About creating explicit object types... I had worked a little with gwt-
openlayers - which is a wrapper of OpenLayers in Google Web Toolkit
(written in Java). What they did was create their own objects. For
example, the Options object which I pass into the Map as a parameter
could be a MapOptions object which you create. The MapOptions class
could have get/set functions for setting the various options the Map
has available. I'm not positive how much work this would add
throughout all of the code base, but it is one option.

Hopefully this answers your questions, but let me know if you have
further questions.

Thanks,
Scott

Hi,

There is no more warnings, embedded images are fixed and the demo
(http://openscales.org/openscales-flexlayers.swf) now use metacarta
satelite layer as default.

Known issues are are listed here : http://openscales.org/p/openscales/issues/

When these issues will be fixed, we will start refactoring of some too
much Javascript oriented code (replace Object by real types, modify
some Utils function ...)

Any help appreciated.

Hi,

Thanks to the contribution of Thibaut and Jeremie, OpenScales can now
display Open Street Map layers !

Try it on the demo : http://openscales.org/openscales-flexlayers.swf
