I am trying to code a tethered placemark in the plugin just like the ones in google earth but I can't find any reference to a single line going from ground up to the pushpin.
Here is what I have so far: what am I missing?
var placemark = ge.createPlacemark("");
var point = ge.createPoint("");
point.setLatitude(41.0);
point.setLongitude(-88.0);
placemark.setGeometry(point);
point.setAltitudeMode(ge.ALTITUDE_RELATIVE_TO_GROUND);
point.setAltitude(500);
ge.getFeatures().appendChild(placemark);
Any help would be highly appreciated Thanks in advance.
You just need to set the extrude property of the KML point to true. i.e.
point.setExtrude(true);
This specifies whether to connect the geometry to the ground with a "tail" as you require.
It is also worth noting that for extrude to have any effect the altitudeMode of the point must be either relativeToGround, relativeToSeaFloor, or absolute.
Also, you can set the properties of the point using the shorthand set method. i.e.
// latitude, longitude, altitude, altitudeMode, extrude, tessellate
point.set(41, -88, 500, ge.ALTITUDE_RELATIVE_TO_GROUND, true, false);

I have a QImage I am able to clip out a QRegion of and successfully clip out the region using the QPainter class setClipRegion() function. However, I want to save what is drawn as a new QImage but am not seeing anything in the docs about saving what is actually displayed.
I've tried directly changing the images alpha channel to match the clipping region but my implementation is very inefficient. The setClipRegion() function was the only thing I learned that could efficiently display what I wanted. My end goal is to use the clipped image as a QOpenGLTexture so I somehow need to save the originally clipped image.
Thanks for any help.
You can simply specify a new file name when saving. so you do not overwrite the old one.
image = QtGui.QImage('orginal.png')
output = QtGui.QImage(image.size(), QtGui.QImage.Format_ARGB32)
output.fill(QtCore.Qt.transparent)
painter = QtGui.QPainter(output)
....
-> your clip path
....
painter.drawImage(QtCore.QPoint(), image)
painter.end()
output.save('new.png')
I made a tilemap. and used it on cocos2d-js.
Just added
this._map = new cc.TMXTiledMap(res.tilemap);
this.addChild(this._map, 0, 1);
in Layer.
But When I use this image,
http://i.imgur.com/f5VG0Nr.png,
http://i.imgur.com/Ugg9GNq.png
this error occured.
[.WebGLRenderingContext]RENDER WARNING: texture bound to texture
unit 0 is not renderable. It maybe non-power-of-2 and have incompatible
texture filtering or is not 'texture complete'
But When I used other image, it works.
like

I changed tilemap many times with that images, but same result.
I don't know what is diffrent that images.
Please help me.
Have you tried I believe I encountered this error once:
Have you tried adding all the image files in your resources.js file?
i am using
map.fitBounds(arrayofcoordinates)
I am drawing multiple polylines to show path for each users moving on map, using fitBounds() complete path is not visible. I want to remove fitBounds() if I click on a marker to see its path. and after that enable fitBounds() to see all markers moving on map. I do not know if it is possible or not. Please help.
If yes then how ?
any help would be appreciated.
You can use a variable as a flag which will have value 0 or 1 . Write fitBounds() inside if statement like
var boundFlag = 0;
if(boundFlag = 1)
{
map.fitBounds(arrayofcoordinates)
}
To change the value of variable "boundFlag" 0 or 1 you can use custom button on leaflet.

Has anyone had an issue with the points returned by the Google Directions API? The overview_polyline doesn't seem to match the directions I've asked for.
The Directions API gives the example:
http://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal&sensor=false
In the JSON response I see includes:

Decoding this using the Interactive Polyline Encoder Utility shows a path starting in Toronto as expected but going a different direction with an end point nowhere near Montreal.
Any ideas?
For background, I'm trying to use the polyline to generate a static map. The static map API allows passing encoded polylines.
I have had success using Mark McClure's tools:
http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/
on archive.org
Your polyline works for me when I use this tool to decode it:
http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/decode.html
on archive.org
and this to display the results:
http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/encodeForm.html
on archive.org
Encoded polylines often have issues with "\" escaping the next character.
See this example [1] (can't seem to get it to display as a link)
with each '\' changed to a single '\'
From this issue where it does display as a link.

I'm trying to create a VolumeSlider widget that changes the volume of my audio output.
log.debug("Starting audio player (%s)..." % url)
mediaSource = Phonon.MediaSource(url)
mediaSource.setAutoDelete(True)
self.player = Phonon.createPlayer(Phonon.VideoCategory, mediaSource)
self.player.setTickInterval(100)
self.player.tick.connect(self.updatePlayerLength)
self.mediaSlider.setMediaObject(self.player)
audioOutput = Phonon.AudioOutput(Phonon.MusicCategory)
Phonon.createPath(self.player, audioOutput)
self.mediaVolumeSlider.setAudioOutput(audioOutput)
self.player.play()
However even though I can move the volume slider, the actual volume doesn't change. What did I miss?
I have never used Phonon.createPlayer, because the API seems totally baffling. Apparently, it is supposed to be a "convenience" function that creates a path between an media object and an audio output. But it only gives a reference to the media object. There appears to be no access to the audio output object, which would seem to make it completely useless (but I may well be missing something).
Anyway, I think it is much more convenient to create the paths explicitly, so that it is clear how all the parts are connected together.
The following code works for me on Linux and WinXP:
self.media = Phonon.MediaObject(self)
self.video = Phonon.VideoWidget(self)
self.audio = Phonon.AudioOutput(Phonon.VideoCategory, self)
Phonon.createPath(self.media, self.audio)
Phonon.createPath(self.media, self.video)
self.slider = Phonon.VolumeSlider(self)
self.slider.setAudioOutput(self.audio)
