I would like to render an image and I don't see a polygon on it. Is there a way to achieve it to be seen on the top right side of the attached image? here

I'm working on simple side project and small part of it is rendering a terrain. I'm rendering the terrain using height map information. But here is my problem:
I would like to render just a silhouette/outline of the terrain/horizon. Here is screenshot from my app rendering height map:
And here is screenshot similar to desired result from peakfinder.org:
I would like to draw just lines representing silhouette of terrain with the rest transparent or solid colour. How can I solve it? Calculate local maximum somehow?
I created sample project here, in case you want to help me.
Thanks!
I would like to rotate a React Native Image based on an x/y point on the image, rather than the default centre.
Say I have a needle image and I want to sweep it around, like a speedometer on a car. I need to rotate it based upon a pivot point at the end of the image, rather than the image centre.
Can this be done?
I'm using PS CS6 and have almost no experiences with Photoshop. I just need to get some sizes in pixels to create HTML.
Maybe a trivial question, but couldn't find any answer on Google and stackoverflow.
Problem:
The main image consists of different layers. Those layers contain an image. How do I get the size of those images in pixels? I could use the ruler but there has to be a much more simple way. Any idea?
Please assist me.
Try this
For Single image (sub-Image)
Select or click on Image than look under menu of cs6 you can show [Show Transform Control] check it and you can re-size your image in any size.
For Whole Image
PS>Image > Image Size > Give Wight and Height in Pixel so u can use that image as HTML file.
Hope It will be work

for images or other objects on a layer show the info palette (F8) and select the object as if you wanted to resize it (eg click upper right corner). The dimensions of the image are then displayed in the info palette.
In PS CS6 simply make a rectangle and you have shown its size next to the cursor. Before this make sure that you have pixels as your main unit in preferences.
Good Luck.
i'm using GPUImage library and i wish to put a small logo or text at certain coordinate of a still image.
i tried using GPUImageSourceOverBlendFilter, it blends the 2nd picture into source picture but default at the center of the source picture.
Can anyone share some idea how i can achieve this?
I've created a canvas within which I display an image that is clipped when it goes over the edges. I can do this fine with a square shaped frame, however the frame I want to use is the one below. Is there any way I can clip the image inside the frame without having to add a non transparent square border around the image, i.e. just using the black line that I've already drawn? (on iPad)
You'll need to use Core Graphics and Quartz to handle this sort of clipping/graphics manipulation.
http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/Introduction/Introduction.html#//apple_ref/doc/uid/TP30001066
If you're using UIBezierPath, you may be able to achieve the clipping you're after using the following process
http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_paths/dq_paths.html#//apple_ref/doc/uid/TP30001066-CH211-TPXREF101
Convert your UIBezierPath to a CGPath
Get your image into a CGContext
Add your CGPath to the context via CGContextAddPath
Clip your context using CGContextClip
Alternatively, if you don't want to be messing with paths (and depending on whether this technique is suitable for your situation, your description of the issue makes it hard to tell), it might be worth using image masking to achieve the effect you're after. See the first link and look under "Bitmap Images and Image Masks".
