Swipe and Spotlight Widget For Flex Viewer 2.x

RobertScheitlin__GISP — Wed, 09 Feb 2011 18:48:41 GMT

All,

I have migrated Tom Hill's Swipe and Spotlight tools to Flex 4 and Flex Viewer 2.x

http://www.arcgis.com/home/item.html?id=b9767b3f300142488c798953a94906fc

The swipe tool behaves similarly to the swipe tool in ArcMap.

1) The swipe tool allows you to compare two layers side-by-side, by selectively masking the top-most of the two layers.
2) The spotlight tool allows you to see through a circular "cut out" of one map layer onto any layers below.

Hi Robert,

Great widget! But unfortunately there are some bugs to fix. You can see attached screenshots with some errors (note status of buttons, tools, and active layers). Some errors are produced because of the widget doesn't sincronyse well with MapSwitcher widget. Besides, in some cases, the swipe buttom don't display the current status (because it appears deactivate and however it's activated), and sometimes the tool botom stays always activated and you can't use the pan tool. Furthermore, when the user select a layer to activate, and it's displayed a message that layer is not visible, if he selects 'Not make visible', the swipe tool should be deactivate. Finally, I consider more useful in case the layer to activate is not visible, don't display any window message, but when the user changes the active layer or closes the widget, the previous one only should be visible if it was visible before opening the widget (do you understand me? - sorry for my bad English).

Regards,
Pedro.

Pedro,

I don't feel like getting into managing what layers were on before the widget and resetting them to that so I just removed the question dialog altogether and now the user is responsible for ensuring the layer that they are trying to swipe or spotlight is on. See if this fixes some of your issues. Of course if you don't like the way the widget does something the source code is always there for you to change it yourself. The live preview site has been updated with the new version I have not updated the download yet though as I am still testing my changes.

I wish I knew Flex to create and modify widgets! (perhaps one day). Concerning resetting layers, I suggested you that because I thought if your widget was able to control if layer to activate is off, it wouldn't be difficult for you, to reset it after changing the active layer. Anyway the most important issue is your widget synchronizes fine with MapSwitcher widget. Regarding to the user is responsible for ensuring the layer is on, I prefer the widget make it visible automatically without displaying any message to user. Thanks so much for your greats widgets!

When do you think will be ready the new version with your changes? Please, check as well the following, in this order:

1. Select Lousville Landbase as active layer.
2. Clic Swipe tool
3. Clic Zoom in tool (below Pan tool) to zoom in an interesting area.
From this moment the Pan tool doesn't work anymore.

Pedro,

That issue is fixed and the download has been updated.

Pedro,

I've downloaded the updating, but it seems the problem I informed you in my previous post is not fixed. Even now in step 3 when you are drawing a rectangle of interested area, at the same time the image is panned. I've checked in your demo as well.

Oh, what a pity! It's a very useful widget to compare layers in a easy way. Perhaps, Esri guys should help you to make it work correctly.

All,

this widget is re-released with the the pan/zoom issues fixed.

Hi,
SwipeSpotlight tool is very good, we would like to use it to work with historical orthophoto. When switching basemaps using MapSwitcher, basemap gets over the active layer and the SwipeSpotlight tool does not work. I added to the widget listen BASEMAP_SWITCH event,where the function does the same as function layerChanged(). Still it is not entirely correct, how to solve it professionally? I'm not a programmer and I apologize for my English (Google Translate).

Regards

Lukas

Lukas,

Are you trying to swipe multiple basemaps? The map switcher actually only allows ONE basemaps at a time to be displayed. Your best path is to have the historical aerials that you want to swipe as operational layers instead of basemaps.

I just downloaded and am testing the 2.5.0.2 version of this widget. The drop-down list will not populate.
There are basemaps listed in the config.xml and I have the "usebasemaps" tag set to true.

Any ideas?
Thanks

It is nice to see these tools updated.
Thanks Robert. 🙂

All,

There is an exciting new version of the widget available:

Version 3.6.1 - Feb 18, 2014
* Added support for freezing the swipe or spotlight mask. What this means is can let go of the mouse during a swipe or spotlight and the mask will remain frozen on the screen until you click again or press the esc button on the keyboard.
* Added the diagonalswipeenabled tag in the xml.
* Added the freezelayermask tag to the xml. This sets the checkbox on the Swipe widget GUI to true or false.
* Added support for multiple layers added to the map using the same label. This mean you can swipe or spotlight basemaps with reference layers and operational layers that have the same label for multiple layers.
* Redesigned the GUI to allow selecting the top and the bottom layer for the swipe or spotlight operations. Setting the layer in the top and bottom drop down lists will move that layer to the top or the bottom of the map respectively.
* When the widget is opened the order and visibility of all map layers are recorded and when the widget is closed they are reset to this original order/visibility.
* Depreciated the askaboutturningonlayer tag as now layers are set to visible by default when chosen in the top or bottom layer.

Is is possible?
if Yes, then please suggest how can i achieve?

Re: Swipe and Spotlight Widget For Flex Viewer 2.x

RobertScheitlin__GISP — Thu, 06 Mar 2014 16:30:34 GMT

Ravindra,

I Can only assume yes, but not being a Java developer and this being a Flex forum I have no advice on how that would be done.
