I'm currently working on Pset4 and my edges function can't seem to get through the CS50 tests. I can't figure out the problem with my code. The errors are-

:( edges correctly filters middle pixel expected "210 150 60\n", not "255 150 60\n"

:( edges correctly filters pixel on edge expected "213 228 255\n", not "255 228 255\n"

:( edges correctly filters pixel in corner expected "76 117 255\n", not "100 117 255\n"

:( edges correctly filters 3x3 image expected "76 117 255\n21...", not "100 117 255\n2..."

:( edges correctly filters 4x4 image expected "76 117 255\n21...", not "100 117 255\n2..."

I have added a few .js files to an xcode project:

I am trying to load those .js files at runtime but they apparently are not available. This was seen by looking at the physical disk location of the simulator sandbox that we can find at: Bundle.main.bundlePath whose value is:

/Users/steve/Library/Developer/CoreSimulator/Devices/CC7AE0CD-4EEE-412F-8E01-E5F55F73887E/data/Containers/Bundle/Application/ECB90596-FF9F-4E40-B500-0D55DDFC0E2E/hybrid.app

Under that directory there are a few gyb files, the Info.plist, some code signature files, the storyboard .. and one .js file. That one file was added to the project earlier and I am not certain using what mechanism.

I'd be happy to see all of the .js files there - but maybe that's too much to ask? Is there a different way to get those other .js files - like reading from some Resources bundle?

I have to apply the Sobel operator to each pixel in my image for cs50 to highlight the edges, so I created a copy of each pixel, then found the Gx and Gy values for each color of the pixel (6 total values: gxR, gxB, gxG, gyR, gyB, gyG). I created 8 if cases for the pixels that were on a corner or on an edge of the picture (I realize it's redundant and very repetitive, but I couldn't think of a better solution on my own). Then, I found the new blue, green, and red values by square rooting the sum of the squares of each corresponding color (e.g. int blue = round(sqrt((gxB * gxB) + (gyB * gyB)));). I capped the color values at 255 (see my cap function) then applied them to each corresponding color in the image. When I run, however, the edges don't show but rather a very bright image does, and the program doesn't pass any checks in check50. Anyone know what's wrong?

Here's the error message (full version here):

Suppose I have this:

I try to generate code by GYB. I did everything and it works perfectly in a new and clean project. Tests and code are generated in the right way. When I tried to integrate my solution in the main project I got a weird message:

I am using Visual Studio 2015 and trying to build an Xamarin solution (Android and iOS app). I am getting the following errors that are resulting in a failed build:

C : error APT0000: \Dev\GYB\GYBMobile\GYBMobile\GYBMobile.Android\obj\Debug\lp\68\jl\res\values-v24\values-v24.xml:1: error: Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Borderless.Colored'. C : error APT0000: \Dev\GYB\GYBMobile\GYBMobile\GYBMobile.Android\obj\Debug\lp\68\jl\res\values-v24\values-v24.xml:1: error: Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Colored'.

I cannot find any information on this. Any ideas what might be causing this?

Thanks!

This is how I managed to use a Sobel Kernel on a GRAYSCALE image.However,I dont actually get how to modify it for a color image.

I'm reading the swift source code on github and I have noticed there are files with the extension gyb e.g. Swift github Integers.swift.gyb.

I did a bit of research and I think (correct me if i'm wrong) gyb is a preprocessor that the swift team wrote so that they dont have to write repetitive code e.g. dont have to write many different version of code for different int types, which only vary slight from each other.

But I dont really understand the python code in which the gyb files are written in. Is there any way that I can transform those gyb files into swift code? so it is possible study how swift e.g. Int type is implemented?
