circuit board drawing program

Recently made a similar Windows drawing board applet, to share with you. The function and the interface all imitate with the drawing board which the Windows own, the interface like screenshot. The main functions are: hand-painted lines, simple graphics, text input, block drag and drop, repeat undo, Zoom, open the Save

modified drag-and-drop operation handler: Public void mousedragged (mouseevent e ){Graphics G = getgraphics ();Copy_from_offscreen_buf (g );X1 = E. getx ();Y1 = E. Gety ();Update_buffer (G, new drawitem (x0, y0, X1, Y1 ));G. Dispose ();} Note: In this method, we didn't update the backend buffer. This is because when you drag the mouse, the line is displayed on the drawing board, but the line is not actuall

Printed circuit boards include the following components: Line and drawing (pattern ):Line as a way of connecting components, the drawing is to meet the special needs of the pad, a large area of copper, fill, etc., the line and the map is made in the same process steps. Dielectric ):To connect, volume and signal, printed

" Aspects of the information, are very vague, the effect is related to the input and output. The IC chip that controls the input and output on the motherboard is Winbondw83977ef-aw. Motherboard power on for a long time and it is not hot at all, so a large integration block will be bad? A little grasp, but decided to try another. Disassemble this integration block rely on the author's soldering iron and tin can not, so to do mobile phone repair friends there, in his 850 hot air welding platform w

Drawing is an important way to mark and visualize data. By integrating the drawing board function in MATLAB, it can facilitate scientific computing. 1. Set MATLAB to support opencv Compilation Operating System: Qilin 14.04 (based on Ubuntu 14.04) Command: Mex-V -> mexopts.sh sourced from directory (DIR = $MATLAB/bin) FILE = /usr/local/MATLAB/R201

process does not simply change the coordinates of the current object. do not tell me If offset is changed based on the current mouse position.These are all in the source code of the second part. Part 2: Isn't the program finished? Why do we have to go through the second part? after reading the second part, we can see that the second part of the code is better, and all the code in the second part is rewritten.The above is still not a good structure.
