language agnostic - Finding the translation between points -

-

I have a map of America, and I have a lot of pixel coordinates on that map that are consistent with the locations. These dynamically form dynamically on the map on runtime according to different settings and statistics.

Now I have to switch to a different map of America, which is differently shaped, and in the top left corner of the map, in a little space in the ocean

So I have manually collected a small group of coordinates for each map that correspond to each other. For example, on the first map, the point (244,312) corresponds to the point (598,624) on the second map, and on the first map (1323,374) corresponds to another map (2793,545), etc.

So I am trying to decide the translation of X and Y dimensions. So the set of points for old and new maps was given, how do I get the x '= a * x + c and y' = B * x + D equation Automatically translate any point from the map to one point?

You have two points coordinates on both the maps, (x 1 , Y 1 ), (x ' 1 , y' 1 ), (X 2 , y 2 ) and (x ' 2 , y' 2 ). 

 A = (x ' 1  - x'  2 ) / (x  1  - x  2 < / Sub>) b = (y ' 1  - y'  2 ) / (y  1  - y  2  ) C = X ' 1  - Ax  1  D = y'  1  - BY  1

PS Your equation shows a simple scaling / translation from one map to another if you are worried about using different estimates from the world to the aircraft, the equation is more complex Will go

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page. What it should do, send the values ​​of the form for Project_Azax.fp, then there will be a refund of success on the page which is correct or false. $ (document) .ready (function () {$ ('div # didIt'). Hide (); $ ('form [name = adminForm]'). Submit (function () ($ {'.post' ('/ project_ajax.php', {action: $ ('[name = action]') Val (), pId: $ ('[name = pId]'). Val (), name ('[Name = name]'.

Val ()}, Function (data) {if (data.success) {$ ('div # didIt') .Sliddown ('slow');} and {warning ('unsuccessful SA!');}}, 'Jason'); return false ;});}); What is the code for project_ajax.php below ... if ($ _ POST ['action'] == ...
