I have a collection of HubTiles with user-selected images. If an image with transparency is selected, the HubTile's background color (PhoneAccentBrush) shows through. Is there a way to style just the photo background to Transparent without altering the animation backgrounds? (Although if the Title is displayed on a transparent background, that's acceptable, but I'd still like the flipside to use the accent color.)
I've done some searching on styling the HubTile, but haven't been successful.
Apparently the fastest way to find an answer on the interwebs is to post your question to SO. I found this not two minutes after posting.
Konstantinos Kyriakopoulos has a blog post with the template styling I was looking for. I couldn't set the image background to Transparent, but I was able to set it to PhoneBackgroundBrush, which works just as well.
Specifically, I set the Background of the Border in the TitlePanel Grid.

I was on the way of making a picasa like photo viewer and later an image editor.i used JFrame and alpha channel to set background transparent.but while moving or zooming in/out ,as i had to draw it on different location and clear the previous image i used clearRect and faced the problem.
the oracle documentation says it clears the rect and restores the background color.
on some trials the clearRect clears the area to background color.But while continuous events like mouse-dragging its turning the color of cleared area to black and causing this:

thnx
.i used JFrame and alpha channel to set background transparent.
Don't use alpha for complete transparency. Instead just use:
panel.setOpaque( false );
If you are using semi transparency then check out Backgrounds With Transparency. It will explain the problems with transparent background and provide a couple of solutions.
The basic problem is that transparency breaks the painting contract with Swing components because the background is not cleared entirely before child components are painted.
Wondering if anybody could help me out. I have the Masonry jquery plug-in which is laying out a set of images and when you zoom in or out in the browser, they change place to fit more/less of the images on the screen. Is there a way to, when i hover over these images, they would fade to black and a description of the image would appear in it's place.
A bit like http://www.flickr.com/ but rather than the small box at the bottom when you hover on an image, a box that covers the whole image and each seperate image can have a seperate description.
some possible hover effects is like Image effects, like grayscale, blur, sepia, etc. I still haven't figure out the best hover effect that have fix height/width.
I want to show a preloader on my website before the content loads,However when i choose a animated preloader image with transparent background the edges look very jagged. How to I modify the image or is there a way to have a transparent background to animated gifs?
I am using the preloaders from preloader.net
The first and probably easiest option you have is to use spin.js. “It dynamically creates spinning activity indicators that can be used as resolution-independent replacement for AJAX loading GIFs.”
If a script is not an option or you want to have a different spinner you have to create a .gif with no anti-aliasing that is bigger than the spinner you want to use and scale it down with html.
Original spinner without edges (without anti-aliasing, therefore it has a pixelated edge):
But if this spinner gets scaled down, it looks nice:
Be sure to use
img {
-ms-interpolation-mode:bicubic;
}
to make it also look pretty in older IEs.
You can use a site that helps you generate your spinner. A great option is :
loading.io
I want to create a mask effect so I place a mask over my panorama page, but this would place a mask on my entire screen. How can I make it so that it would only place on top of my panorama background but under my panoramaitems?
You could retemplate the the Panorama control to add the mask over the background image.
I've found some issues with doing this in Mango though and so have chosen to manipulate the background image directly. This also led to code which was simpler to follow. (In my opinion.)
First of all I will explain my situation so you can know my problem a little better. I'm making a HTML5 app. I have a canvas, and using a color picker you can change the color of the canvas. Now i have a picture which I want to put on the canvas but that pictures color needs to be changed using a color picker. So i need to replace, lets say, black color on that picture and put it on the canvas so it dosnt screw up the background.
So that will look like this:
1st color picker- changes the color of the canvas
2nd color picker - replaces the black color on the image with the one in the color picker and puts it on the canvas
Now my problem is how to replace the color on the image without reloading the page.
My only condition is no using silverlight, flash, java or any other similar tehnology that need 3rd party software to be installed on the device.
Thanks in advance.
If you dont understand my query fully, feel free to ask.
My approach with a JS only solution could be:
Loading the image inside a canvas element. Look at the MDC canvas tutorial
Trigger the user click on the canvas and get the pixel color (see links below to know how to get the color of a pixel) and look at this answer to get the mouse position
Substitute all the colors in the canvas with the one the user pick. For some examples about pixel manipulation:
Pushing pixel with canvas at Mozilla Hacks
http://beej.us/blog/2010/02/html5s-canvas-part-ii-pixel-manipulation/
This JS at mezzoblue apply heavy filter to an image
After some canvas experiment I notice that mostly in all the browser the pixel manipulation with canvas could be very slow also with small images. So another experiment to do could be to get the pixel color and then:
pass the color information to a PHP (or another server side script) with an AJAX call
do the color manipulation with an image library like GD or imagemagik
return back your image with the Ajax response
reload your canvas with the modified version of the image
