I started this adventure by modifying a pretty decent little script (thanks to jqueryfordesigners.com): // wrap as a jQuery plugin and pass jQuery in to our anoymous function (function ($) { $.fn.cross = function (options) { retur...
I create a simple WPF UserControl (any control will do) and insert it into a Winform (using an ElementHost). This works fine. The WPF control is embedded in the WinForm and when the WinForm is moved around the WPF control moves with it just like a WinForm control will do. When I change the WinForm to transparent by setting the Tranparenc...

I tried the following new GTileLayer(null, _minZoom, _maxZoom, { isPng: true, opacity: 0.6 }); But in IE8, while the alpha opacity works, the pixels in the PNG that already had translucence they show a grey color and standard opacity. I have noticed also that PNG files that contain alpha transparency and their transparency is not mod...

The PictureBox will always have the size of 300*300 with white background. No transparency is needed for the control. What I need is the way to draw the transparent rectangle (or whatever else) onto th...

For example from 0 to .7 but everything I can find just fades either from 0 to 1 or 1 to 0. I can't find anything that lets you specify from what to what. My attempts of reverse engineering the functions I have found have al...

Hi, I've been trying to create a transparent table view recently but I'm not having much luck. The idea is to have a MapView (or anything for an example...) underneath the table view (grouped) where the table cells are solid but the rest of the table view is transparent, showing the map behind. What I've done so far is create a UITable...

However the threshold() method's sourceRect parameter is a Rectangle and I need mine to be a circle. This is the method: **public function threshold(sourceB...
