I am trying to add folded effect onto mapview similar to map in this image http://dribbble.com/system/users/11236/screenshots/311711/app-ui.png?1321121645. Tried to google for it but without luck. Any help would be greatly appreciated. Thanks!
My guess is that they are just overlaying an image with the folds/shadows/edges to give the effect. The actual map itself does not look like it is manipulated at all.

I am working on a drawing app. I have implemented the drawing string feature using CGPath. The next feature is that I can click on the view. If where I click includes an enclosed area, I can fill it with other colors. I am thinking that I need to get the enclosed subpath first, then fill color to it. Very much appreciate it if anyone can give me any idea. Thanks.
For you to understand it, I post a picture.
Okay, finally I found what I want is the "Flood Fill" Algorithm. If anyone wants to look for the referring article, please see here
As you can understand from the title of this question I am trying to achieve fill animation of CALayer(CAShapeLayer) of SVG file.
How complex should be animation you can see from the images I attached.
I decided to start just with a circle and animate it to fill a layer below. Everything works pretty well.
So, I started building UIBezierPath or something like that but it looks like I am going the wrong direction.
I would really appreciate if you can just give me different ideas how to achieve it.
For SVG I use SVGKit. Maybe by using these set of classes, I can do something.
Thank you!
I'm having trouble with positioning a rectangle in an image. Please see attached photos!
I need to determine the position of the rectangle (black) in the image.
Help me write code with OpenCV. I'm trying to rotate the image based on the black rectangle.
Thank you!
P/s: Because of its ability to present my poor english, hope you understood ignored. Thank you!!

Now I have found a method. The information you see here: http://felix.abecassis.me/2011/10/opencv-bounding-box-skew-angle/
It can rotate images automatically!!!
I got an UIView with 4 views in the corners which will be dragged to create a perspective effect. This is how it looks like in the beggining:
Once the user drags a view, it will create a transform effect. For example:
I investigated it and I figured out I have to use CALayer to do that, but I'm still no clearer on how to create this kind of transform on an iPhone. Any help, pointers or example code snippets would be really appreciated!
Thanks!
You should search for CATransform3D. But this is kind of a good start.
I trying to draw same images along a straight path.
I already know where the path begins and ends.
How can I make it?
Please Help.
Always thanks.
can you please Explain the condition,So that i can understand the way you want draw images...
As I understand your problem you want to draw series of same image along with a path, in that case you can use CCRibbon.
