QUESTION
I am working on a logic of correcting width, height and angle of page(image). Point r1,r2,r3 are on correct image and Point d1,d2,d3 are corresponding points on current image.
I have tried multiple approach and have landed on this.
...ANSWER
Answered 2019-Dec-24 at 12:37I am not answering your question directly: But a common technique to align a scanned image is to use an affine transformation. It is a 3x3 matrix equation based on a,b,c,a',b',c'. With a simple matrix multiplication you can then calculate every coordinate within the one ot the other image system or make complete transformation of all pixels.
Sorry to have no working example for you. See https://www.graphicsmill.com/docs/gm/affine-and-projective-transformations.htm and https://docs.microsoft.com/en-us/dotnet/api/system.windows.media.matrixtransform?view=netframework-4.8 is used in WPF RenderTransform.
QUESTION
I have an Xcode project (objective c, Xcode 8.2.1).
Whenever I do "Clean build" and build again, it takes a very long time. I started to look into the reason for this and I noticed that all my pod source files are being compiled twice (which I guess doubles the compile time).
At the top of Xcode, you can see the status of the build as it progresses
You can see in the screenshot above that Xcode is compiling 142 source files for the Realm pod, but it only has 71 source files. All my other pods have the same issue.
I tested creating a new xcode project and adding pods, and then I don't experience the same problem as in this project.
@Bdash suggested that I might be having the build setting "Build Active Architecture Only" set to "No", but I have checked this and it is set to "Yes".
Any ideas on what could be the problem here?
...ANSWER
Answered 2017-Mar-03 at 18:30Unfortunately, Realm is a large project with a significant number of C++ and Objective-C++ source files, and generally takes a while to compile (especially after cleaning the build folder). Exactly how long Realm takes to build depends on what sort of computer Xcode is running on, but the numbers you provided don't seem to be unreasonable for older hardware.
QUESTION
I've just updated Xcode using Swift 3.1. While waiting for Realm to update their library, just wondering if someone has a temporary workaround for this issue.
Module compiled with Swift 3.0.2 cannot be imported in Swift 3.1: RealmSwift.framework
EDIT:
@matt, @bdash, I followed the instruction, removed the old libraries and added new supporting swift 3.1. I got this error
Showing All Issues Command failed due to signal: Illegal instruction: 4
Any idea?
...ANSWER
Answered 2017-Apr-01 at 02:55Realm Swift v2.5.0, released earlier this week, contains a precompiled framework binary for Swift 3.1. No waiting required.
QUESTION
I have a website at. If you try to use the search box it gives a server error. For some reason it is not connecting properly to the Google Site Search and will not bring the results to the page. It at least took me to the search results page before I uploaded it to the server but after it just gives an error. I am new to setting this Google Site Search up on my own and I don't understand what I am missing to get this working.
search.html:
...ANSWER
Answered 2017-Jan-17 at 03:59I fixed this just by changing my search.html to search.php and then loading it back up onto the server. Makes sense it was something that simple. Code is below, thanks to all who helped me out.

Answered 2017-Feb-01 at 10:08It seems that you simply need $lines
for processing in the foreach
loop.
Either get them as arguments passed to the function
