Developing a Paint program with GTK (Windows)

GTK is a powerful development platform, cross-system, provides a rich and extensive code base, application developers can quickly make their own products.

This month with him to develop a GUI program, is a drawing tool, features include: Image import and export, line editing, drag, delete, adjust the thickness, color, actual situation, shadow, the highlight is to achieve a custom style: sharp-off line (the project will add more Linetype). The sharp-off line is a commonly used drawing line in petroleum exploration data processing. The process of using the GUI is to import a basemap first, then draw lines on top of the basemap or insert other pictures, text, and finally export the whole as a picture. Example of the sample:

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M02/4C/6E/wKioL1Q9KBeB7wNNAAacs0dspcA178.jpg "title=" A.png " alt= "Wkiol1q9kbeb7wnnaaacs0dspca178.jpg"/> Penguin chart is a background map, the Blue line is a sharp-off line, there are some other lines and menus.

The development is based on the Windows GTK + platform, with C language development. After the initial tuning, the results are still satisfied:), now drag the line when the screen is very smooth. will be uploaded to GitHub later on.
