Linux Lake 11: blog must be the five major image processing artifact

When you send a blog, you always have to use pictures to speak. After a long run-in, the Linux desktop system has several image processing software I have used more comfortable. These software are widely used in the Linux world, each Linux distribution version of the Software warehouse has its own installation package, and these software run stable, beautiful interface. It is recommended here for everyone.

Please look at my desktop, the five icons on the left side of the luancher are the five image processing tools I will introduce today:

First, the tool gnome-screenshot

This software does not install itself, it is the GNOME desktop comes with the software, generally installed after the installation of the Linux system, its software name is Gnome-screenshot, Chinese name is called, very direct. Although there are many other better software under Linux, I think the system comes with enough. and very useful.

With this tool you don't even need to run it specifically, just remember that several shortcuts to the GNOME desktop are sufficient, and these shortcuts are as follows:

1. Printscreen key: Directly press the "Print Screen" button in the upper right of the keyboard, you can do the whole screen, "click Wipe" After a sound, will be out of the dialog box to save the picture, very convenient.

2. ALT + Printscreen key: If you only need to do the current window, press ALT + Printscreen.

3. Shift + Printscreen key: If you just want to do a certain area, press Shift + Printscreen, then the mouse pointer changes shape, hold down the left mouse button drag, select which range on the screen can be to which range.

Second, bitmap processing software gimp

This software can be regarded as the Linux system of Photoshop, powerful. It is because it is powerful that it has to be done in order to harness it. I used to have Photoshop Foundation, so it's not too difficult to get started with the software. The initial interface after startup of the software may not be as good as everyone's custom, such as:

However, with the Single Window mode option in the Window menu, you can change to the following interface:

Third, vector drawing software inkscape

First look at the Inkscape interface, the function is very powerful said:

Why am I here to introduce a bitmap processing software, and then introduce a vector drawing software? That's because there's a difference between bitmap processing and vector graphics processing. For example, I often want to highlight a command or menu in a picture I've cut, and I'm used to drawing a red wireframe accent on the target. For the picture frame such a simple thing, in the vector drawing software, the frame is a picture frame, after the frame can change the border color and style, you can change its fill color and style, you can drag its position, you can change its size, but the bitmap processing software, you have to change a mode of thinking, In bitmap processing software, the frame can only create a rectangular selection, then stroke and fill the selection, once the stroke and fill end, the box can no longer change. So Inkscape is perfect for working with boxes and text, and GIMP is a great way to do work on selection feathering, irregular area transduction, adding shadows and glows. In my Java blog, there is a repeatedly see the implementation of the game, where the picture is handled with GIMP, Bowen Address: http://www.blogjava.net/youxia/archive/2014/02/14/409871.html.

四、一款 is more suitable for programmers using the drawing software dia

The DIA function is also very powerful, its biggest advantage is that it contains many image elements, it is very suitable for drawing flowcharts, UML diagrams and other various. The interface is as follows:

Five, a grand recommendation of a UML modeling tool Umbrello

In order to find a good UML modeling tool I have spent a lot of thought, the best tools for money, such as Rose, Enterprise Architecture, Microsoft Visual Studio and so on, there are a lot of Eclipse plug-ins, But quality is always not so satisfying. After a multi-test, I finally chose Umbrello. This is the KDE desktop's own modeling software, but it works perfectly under the GNOME desktop. The interface is as follows:

Compared with DIA, its greatest advantage is to support the forward function and reverse function of UML. That is, it can generate code from a UML model, or it can generate UML diagrams from the code we write. And Dia is purely a drawing tool, UML diagram is a diagram, it can not understand its connotation, but also can not generate code.

Well, write so much today, I hope everyone enjoy Linux.
