Android :: If Its Zoom In Or Zoom Out On Flex / Air TransformGestureEvent
May 13, 2011
Using flex / air 2.6 working on an Android device, I am using a canvas with a TransformGestureEvent for zoom in on a map. The listening of the efect is working ok, but I can´t seem to find the information on wether the user intended zoom in or zoom out (fingers getting closer or getting apart).I expected the intention of the gesture to be identifiable with the offsetX and offsetY properties of the event, as you will do on a swipe gesture event. But I always get 0 for both properties, no matter how I do the gesture in the device.How can I know if the fingers getting closer or getting apart in a gesture zoom event?

i've made a button that zooms into a movie clip on a rollover, but it on moves it a certain amount each time you rollover the button. code below:
on (rollOver){
_root.Mypic._width += 5;
_root.Mypic._height += 5;
}
wot i want it to do is to continue zooming in for as long as the mouse is over the button, is there anyway i can change the code to zoom in at the same amount but do it continuously until the mouse is moved off the button. Also is there anyway that i can set it so that the zoom stops at a certain percentage, i.e. it only zooms in so much and then stops. What i mean is that the user can zoom in but the picture will only zoom in to say 200% of the original size.

I am working on flash application TELESCOPE or Camera. My goal is to move around the scene and zoom-in or zoom-out I found that if I move scene, I have to move registration point, because I always want to zoom in the centre of my ocular. So far application works fine only if I move, zoom-in and than before I move any further, zoom-out! But when I move, zoom-in (not fully), move again and zoom-in again, the second zooming doesn't appear on desirable registration point

I have a flash application written in actionscript 2.0 that shows vector architectural maps and works perfectly on common web browsers. There are many interactions with javascript functions called by user events on the webpage, such as zooming to a certain x,y point. This event is usually accomplished via the mouse wheel.
Now I have to make sure that the thing works on tablet pc, in particular the Galaxy Tab. The first thing I have to fix is that, obviously, there is no mouse wheel and the user naturally tries to pinch zoom the flash application, with the result of zooming the entire web browser.
What I need is to listen to the multitouch gesture and, when a pinch zoom event is called, disable the default zooming event and call a javascript/flash function that allows my flash app to zoom only the objects that need to be zoomed: in few words, the browser stays still and only a part of the flash zooms in or out.
I already have working javascript functions to call flash object functions for the zooming purpose, so I just need to connect them to some android things that tell me when the user tries to pinch zoom in and when he tries to pinch zoom out (and possibly the x,y point of zoom).

I'm developing a full screen zoom/pan UI. Everything is working great, except I can't get it to center on the correct point when zooming in.
You can view what I have here: [URL]
The numbers in the top-left corner are the navigation, and the white boxes represent the individual sections.
I have a large container movieclip that fills the entire page. Inside of that movieclip (site) I have all of my individual section movieclips (section1-section6). I'm also using a dynamic registration point class to dynamically set the registration point of the "site" movieclip to the current selected section, so that the zoom in/out is centered on that section.
When a user clicks on a navigation item, I first reduce the _xscale and _yscale of "site" to 80, when that is complete I move _x and _y to the position of the selected section's movieclip. When that is complete, I set the _xscale and _yscale back to 100. Right now, it is not zooming in centered, so I have a final step where I correct the _x and _y position after zooming back in.
If I don't zoom in/out I can successfully pan the movieclip and center on the correct section. I believe the problem is that I am moving the _x and _y to the position of the "site" movieclip as if it is at 100%, but since it is at 80% it is not moving to the correct position. I tried to fix this by giving the _x and _y coordinates as:
endX = endX / 100 * 80;
Which made it a little better, but still not centered. I have a feeling that there may be a fundamental flaw in my approach to this.
For some reason the forum won't let me attach my .zip, so I posted it online, as well: [URL]
My code below, in case you don't want to download the file:
Code:
tile._alpha = 0;
currentSection = section1;
//** Set Stage **//

Do they binding all the layers to make it a movie then resize it on the movie or what?

I came across this great tutorial on how to zoom into a chart by drawing a rectangle in a LineChart to zoom into it [uRL] but I'm trying to apply it to a PlotChart instead and I'm having issues trying to get the DataTips showing with the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.charts.series::PlotSeries/findDataPoints()[E:dev4.5.1frameworksprojectschartssrcmxchartsseriesPlotSeries.as:961]
at mx.charts.chartClasses::ChartBase/findDataPoints()[E:dev4.5.1frameworksprojectschartssrcmxchartschartClassesChartBase.as:2069]
at mx.charts.chartClasses::ChartBase/mouseClickHandler()[E:dev4.5.1frameworksprojectschartssrcmxchartschartClassesChartBase.as:4823]
The link mentioned about extending the LineChartSeries and override the findDataPoints() function, but after trying to doing the same for extending PlotSeries.as, sortOnXField seems to be undefined and I don't have access to the PlotSeries.as since it is in a swc. Has anyone tried applying the following to a PlotChart instead and got the DataTips to show? What was the override function in the findDataPoints()?

There is an Image control that when I click on it I need to zoom in (using the center/transform point where the mouse is clicked). I have the zoom transition working great, but when I set transformX & tranformY (with autoCenterTransform false) it doesn't zoom into that point.
Here is my code that only zooms in (not to a specific point)
<fx:Script>

protected function imgLogo_clickHandler(event:MouseEvent):void {

I'm developing a web app using Flex. This app allows to draw forms in a Canvas (like MSPaint in Windows).Now, I want a new feature on it: an infinite canvas. The user should be able to drag the main Canvas and this should be infinite in X and Y axis. Consecuently, this Canvas should be resized in real time.
Obviously, I don't want to create a Canvas of 1k x 1k pixels with zoom in an specific area to give the feeling of an infinite drawing area.
EDIT:I just read that Flash/Flex Flash/Air supports canvases up to 4056x4056 px, not infinite.

I want to introduce a canvas component by zooming from a height & width of 0.0 to 1.0. I want the component to be invisible until the zoom begins and then for it to be visible when it begins zooming.
However, if I bind the zoom effect to a showEffect trigger on the component and then make the component visible, it will first show the component at its regular size for a split second before it begins the zoom effect. If I combine the zoom effect and setting the component visible together in a parallel, it will also flash the component at its regular size for a split second before the zoom. If I make the component visible when the zoom effect starts through its effectStart event, it still does it. Does anyone know how to make it visible only when the zoom effect begins so that it doesn't flash the component at its regular size for a split second before the zoom effect?
