The Mask filter can make a rectangular mask of HTML component objects on a Web page. What is a mask? If you use the mask in Flash, you will know, that's it. In fact, you can also understand the mask, the equivalent of a colored cloth to cover the object, but the content has
are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts.
From the above introduction we know that the IP address is the network number and host number to indicate the host on the network, only in a network number under the computer can be "directly" interoperability,
computers with different network numbers need to be connected through gateways. But such a division appears and is very inflexible in some cases. For this reason, the IP network
Subnet mask (subnet mask) definitionIt is a bitmask that indicates which bits of an IP address identify the subnet on which the host resides and which bits identify the host. The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide
The Ip2long IP address is converted to an integer type.Long2ip integer data is converted to IP. The subnet mask is converted to a mask length mode:$slash _notation = strlen (Preg_replace ("/0/", "", Decbin (Ip2long ($subnet _mask)));$bits =strpos (Decbin (Ip2long ($mask)), "0"); The subnet mask bit length is converted
The Mask editing box (Maskedit) is a special edit box. Use it to design a number of complex input formats. After selecting Maskedit, you need to design an input format for it. The method is as follows:
First select the Maskedit on the form, locate the Editmask property in the Object Viewer (Objects Inspector), double-click it, and pop up a dialog box as shown in the following figure.

In FLASH7 and the following versions, as is not a direct cutting of the image, and in these effects, without cutting, is not allowed to split the picture into multiple units to move independently. So, how does this work out?
First look at the following two map:
You can see that the same image, with the same mask, and then change the position of the mask, you ca
In Flash8.0 's works, we often see a lot of dazzling magical effect, and many of them are done with the simplest "mask", such as water waves, kaleidoscope, Hundred-page window, magnifying glass, telescope ... Wait a minute.
So how does "mask" produce these effects?
In this section, in addition to introducing the basics of "masking", we also introduce some "mask
Masks in the PS of the application is quite extensive, the mask is the biggest feature can be repeatedly modified, but it will not affect the layer of any structure. If the mask adjusts the image is not satisfied, you can remove the mask original image and reappear. It's a very magical tool.
We usually say the mask
places, while the number of hosts is too small, therefore, the host addresses it provides become increasingly scarce. Currently, in addition to using NAT to allocate reserved addresses within an enterprise, a high-category IP address is usually further divided, to form multiple subnets, which can be used by different user groups. This is mainly to effectively use the IP address in the case of network segmentation. By taking the high part of the host number as the subnet number, we can expand or

In addition to the FLASH DRAWING API allows us to draw graphics, we can also use it to draw a mask, which is the characteristic of the rendering of the mask we can dynamically draw.
how to draw a mask using the Flash DRAWING API
The masks provided by MM are as follows
Tutorials like Fly's friends introduce PS mask principles and examples of application, masks, channels, history, layer styles, blending modes (already started), smart objects, smart filters, embedded layers, actions, other, later I aimed at these, talk about the application, I hope we have a deeper feeling. Enjoy the fun of learning theories.
Let's start with the mask.
When it comes to masking, understand
1. Clip Masks Create text effects
A clipping mask enables you to use the contents of one layer as a mask for another layer. This approach is especially important when you need to display pictures in text. Just create a text layer and put the picture on top of the text layer, and then hold down the Alt/option key and click between two layers in the layer panel. If you've created a clipping
The subnet mask is used to determine whether the IP addresses of any two computers belong to the same subnetwork.
The simplest understanding is that after the IP address and subnet mask of the two computers perform the and operation, if the result is the same, the two computers are on the same sub-network and can communicate directly. That's simple.
See the following example:

GitHub also saw a good animation (https://github.com/rounak/RJImageLoader), so I would like to realize the following do not know, this animation is not really look so simple, I think for a half day Leng didn't do it, Finally read the author's code, just know how to achieve. But also from the author where to learn a trick, is the use of layer.mask. Your own implementation of the effect of the demo here: Https://github.com/Phelthas/LXMRevealDemo (front of the Circle animation, which is a cashaperl
Label: SP data BS amp network nbsp c ip computer When I used to configure a static IP address for a linked router, I only knew to change the subnet mask to 255.255.255.0. Just change the first three digits of the IP address and the last digit of the gateway to an unused IP address, I have never understood what the subnet mask means. Before I took the course "Computer Network", I heard the teacher say that
You can add an empty mask to an object. It can be either a "display mask", an area that displays a mask, or a "hidden mask", where the shaded area is hidden.
(An empty mask is primarily used for bitmap editing mode masking)

From the first contact PS5.0 to now, PS has a lot of functionality, and PS will always retain the functionality of the old version, which I have been following the new version of PS trend. In this there are many enhancements to the function for a purpose, reuse (reuse), do not damage the original piece, can be edited later. Implementation of a lot of features, slightly interested in the following, slowly explained later.
