I'm going to extract the pictures from Heroes III def files. All pictures extracted as a bmp file with blue background. I want to use these pictures in my cocos2d-x project for demo purposes.
How can I use program (GLBlendFunc or Shader?) to make the blue background transparent and choose the shadow visible or not.

I recently started using Libgdx for the first time and I'm trying to make a 2D game similar to Zelda/Pokemon.
The problem I'm having is that I don't know how to make the sprite blend with the background (a tiled map .tmx file). I tried using enableBlending() but it doesn't work. I want the white space around the sprite to be removed so that the tiled map background shows.
tiled map with the sprite
Thanks
Blending is not required in your case.
Just use .png(having transparent background) file instead of .jpg(having white background).
So I have a simple texture: one big green circle in the center and one small white circle also in the center of my texture. And now I want to change color of my white circle to yellow in my app. Is it possible and what is the best way to set color of my batch for specific region? I saw it is possible in other engines using the second texture with marked region which color will be changed.
Like that:

My original texture
2nd texture with region which color i want to change
The result of my texture in app which will be working like batch.setcolor but only for specific region (pixels) in my texture
If you are looking for an example of masking textures together, you can check this tutorial.

It also has a port to libGDX.
Does anyone know why my Win Phone 8 app tile doesn't show the icon I set? This is what I get (and yes, am am sure that's not my app's icon):
This is what I have so far and I ran out of ideas of what can be wrong:
The small icon is a png of 110x110
The medium icon is a png of 202x202
Both images have the build Type = Content
Both images have the copy to output property = Copy if newer
The application icon is the same as the small icon and it shows alright in the program list.
Here is a part of my app's manifest:
<TemplateIconic>
<SmallImageURI IsRelative="true" IsResource="false">Assets\Icons\AppIcon_small.png</SmallImageURI>
<Count>0</Count>
<IconImageURI IsRelative="true" IsResource="false">Assets\Icons\AppIcon_medium.png</IconImageURI>
<Title>
</Title>
<Message>
</Message>
<BackgroundColor>
</BackgroundColor>
<HasLarge>false</HasLarge>
<LargeContent1>
</LargeContent1>
<LargeContent2>
</LargeContent2>
<LargeContent3>
</LargeContent3>
<DeviceLockImageURI IsRelative="true" IsResource="false">
</DeviceLockImageURI>
</TemplateIconic>
If you use TemplateIconic tile the images need to be transparent icons as outlined in Iconic Tile template for Windows Phone 8 because it is just going to end up being a white icon inside a tile. Your image appears as a white square because it does not have any transparency. With the images you have, you would want to use the TemplateFlip tiles and adjust the size of your tiles accordingly.
I had the same problem.
After a lot of brainstorming I tried this and woah it worked!
Check if the image you are setting has a white (or other) background color. If it has, remove the background from the image using Photoshop(Tool: magic eraser) and keep the background transparent.
Replace this transparent background image and it will show up in emulator!
Hope this works at ur end too! :)
Did you look at the manifest file? You can choose the images in that file. I mean using the UI in the studio, open the manifest file and choose the image.
According to Iconic Tile sizing info in Iconic Tile template for Windows Phone 8, both small icon and medium icon must be design with transparent background.
The small icon is a png of 70x110
The medium icon is a png of 130x202
If you need to set the background color, set the BackgroundColor in WMAppManifest.xml as follow.
<BackgroundColor>[hex ARGB format color]</BackgroundColor>
I work with Xamarin.Forms (Shared) for my WP-app and also had problems to implement the Tile in the WP-part of my project.
To set the background to transparent to the tile image have done the job.
But I have used images with 158x158 and 336x336 what also works and allows to use the standard-icon (in a higher resolution) what - I think - most users want to do.
I have created a short description for all visitors, who use XF for WP-development (including app-icon, splash-screen and Tile).

In a Metro App, when retrieving the Thumbnail of a StorageFile using the GetThumbnailAsync() method, the Background Color is a Dark Blue/Navy Blue.
Is it possible to override this Color? I would like the Background to be Transparent.
From the documentation,
The thumbnail is an icon on a background of appropriate size. The background color is determined by the app that is associated with the file.
Combined with the following note:
Note If the associated app is a Windows Store app, the app's tile background color is used.
If your app has an association with the file, just make sure your apps Background color is Transparent (not 100% sure you can do that, actually).
The other option is to use something like WriteableBitmapEx to find every pixel of the tile color, then turn those pixels to Transparent. Shouldn't be too absolutely terrible, but will have an overhead (naturally).
Hope this helps and Happy Coding!
I want to load the image dynamically in Flash actionscript, like this :
When the user select the image it should contain inside the frame instead of black plane box. I am thinking If I can apply that image as background image for that black plane box (which I draw separately inside the frame) that would be great. Because over here the issue is the image should look like 3D inside the frame, so maybe the background or texture method will solve this problem. Please friends give me suggestion...
Thanks.
