I am not sure if this question suits stackoverflow or not. But here it goes, I want to have an image strictly of the shape and size of the main object in the image, there should not be any white or black background, or the background should be transparent so that the real background should be visible. How can I do it? is it possible using photoshop? I want to use these images to create a slideshow in flash.
Yes, you can do it by creating an image with transparent background in Photoshop.
use transparent images and save it e.g. as png

Hey I want to create an app that is similar to these 'face juggler' apps, and other apps in which a photo is taken of the user, then you can drag an image on top to add effects. I have seen one with sunglasses, and i would like to do one with hats (for my brand).
So essentially I will need to be able to take a photo or select from library, then place it in, then add this image over the top which can be resized and moved, then I would need to export the final image to camera roll or facebook etc.
Does anybody know where I should start? I am quite new to this and couldn't find any guides or related questions
Thanks for all your help
A very useful source is the Core Image Programming Guide from Apple. In these document you will find all you have to now about image filter and image manipulation. But first you have to implement a UIImagePickerConroller. With this controller the user of your app can take a picture by using the device camera or by picking an image from the library.

I'm working on box plot using R. I have already plotted one boxplot and now i need to put a pointer somewhere on box plot?
input<-c(1,2,3,4,5)
boxplot(input)
How to import or design an arrow image at position 1.5 on boxplot?
To place a single image on a graph look at the rasterImage function. If you want to put multiple images on the graph (possibly using them as plotting points) then the my.symbols and ms.image functions in the TeachingDemos package may be helpful.

I need to repeat the background image strip, which is from inside of the sprite image format. i have aligned the images in sprite in vertical.
The short answer is no, you cannot repeat a part of a sprite image.
What you could do is use repeat-x to repeat the image on the horizontal axis, but your repeating image segment must have the same height as the element it is assigned to, and all other sprites present in that larger image must be above or below your repetitive segment.
(Similarly, use repeat-y and place all your other sprites to the left and right of your background segment)
Your best option is to cut out and use the 5x5 pixels background from a separate image, which you can easily repeat over the entire element.
You can try:
Background-repeat:repeat;
You will need to use background-repeat: repeat-y; or background-repeat: repeat-x;

I have a problem with render to texture. The texture is mapped on each polygon instead to the whole object. Here in the Qualcomm Forum the problem described in detail again from User andreasv. Can you help me? I need to bake the texture with another program?
I had this problem in a engine I work with, for me I solved it by checking the uvw channel, on my baked objects it set it to channel 3, but on export it exported channel 1, give it a try, check the id in the faces, and in your material (the bitmap in the material you apply).
Try and set them both to using channel 1.

I am looking for a basic example of HTML5 <canvas> animation. For example, making a ball bounce, etc.
If someone has one I would be very grateful.
Here’s a (very) basic bouncing ball animation example:
http://html5.litten.com/simple-animation-in-the-html5-canvas-element/
Here’s a less basic example: a <canvas> cartoon:
http://www.canvasdemos.com/2009/10/09/html-5-canvas-animation/
There’s a tutorial over at Mozilla too, which includes an explanation of basic animation:
https://developer.mozilla.org/En/Canvas_tutorial
I think <canvas> is just a drawing surface, rather than something that has any animation capabilities built in. So I think you’re going to have to do a lot of the heavy lifting yourself (with the caveat that I don’t know anything about animation, so I don’t know which bits qualify as heavy lifting).
