Some of the content of the ICMP protocol is described a lot. We will not go into details about its basic content here. First, for its applications, we know that it is often encountered in firewall settings. Today we will introduce some specific instructions in the Ping command. For inbound icmp usage.

Previously we came to the conclusion that:
For the same dip, the relative width of the screen is the same on the screen with different resolutions. The relative width can be understood as the percentage of a widget's screen.
When density = 160, 1dip = 1px
We can get this formula:
Desity: 160 = px:
Laplacian
Differential Operators
Definition
The single-threaded differential operator is the Laplace operator, a two-dimensional image.F (x, y)For exampleBelow:
Set (2),(3)Type substitution(1)Style
Write the weight matrix template
The effect is as follows:

Convert a color graph to a grayscale image
Finally we make a simple color space transformation, the image from the Rgba into gray.
Copy Code code as follows:
function Cvtcolor (__SRC) {
if (__src.type __src.type = = "Cv_rgba") {
var row = __src.row,
col = __src.col;
var dst = new Mat (row, col);
data = Dst.data,
Data2 = __src.data;
var pix1, pix2,
Problem Description:
1, the PIX placed in a fixed IP environment (external network for fixed IP), and set the correct ACL allow ICMP release, this case intranet can be normal Internet access can also ping the extranet.
2, and then put the PIX in the ADSL environment (with PIX to dial), ACL or before the same, PIX und
Application Identification Application Identifier;aidConsists of a registered application that provides a trademark (RID) and a dedicated application identifier extension (PIX)
AID: Uniquely identifies an application, divided into two parts, RID (5 bytes) +pix (up to 11 bytes)
RID: The registration identifier, assigned by the ISO organization, identifies a globally unique application provider, typically

variables involved in the above code are integers (POSX and posy, of course, are floating-point types).
The sample array in code holds the image data sampled from it, samstride the scanned row size for the image.
Observe the code above, except that there are 2 of them involving floating-point computations, and the rest are the operations between integers.
