I want to start a circuit project which is based on current LibreCAD open source.
Task 1. Design a circut diagram.
Customized icon and graph （"input trigger gate "and "AND gate" and "Or gate" etc..） which can draw this object directly by menu->Draw->AND gate. the icon look like a "&" surround with a rect filled with gray color.
After complete a circuit design, I will save it to a dxf file. take example aaa.dxf.
Task2. open and resize aaa.dxf into specific area.
I will start a project (still based on LibreCAD )which will use this aaa.dxf, but because I will put other picture on the main workspace, so I need narrow the height of content in aaa.dxf .
I mean if the screen is 800x600. I will display aaa.dxf into a scrollview size of 800x300. because I will use rest 800x300 for other use.
Task3. I will use some algorithm to change the input trigger gate. such as there are two input
input1
input2
output12
input1 & input2 = output12.
if the value of input1 or input2 is changed , I might need change the output12.
I really don't know how to implement this requirement currently ....
after I load aaa.dxf, does all of those symbol stand for an individual var in RAM? if that, how to distuiguish which of them should be changed the property of color .
Is there any suggestion and guide from you ? Appreciate your help firstly.
