## dxf_reduce dxf文件处理库，可以创建、加载dxf文件，并向其中添加新的图元。目前可以添加进去的图元有： + Arc + Circle + Line + LwPolyLine + Text + Ellipse + Ray + XLine 支持对图元进行填充的图元有 + Arc + Circle + LwPolyLine 有待加入的图元有 + 3DFACE + DIMENSION + HELIX + IMAGE + INSERT + LEADER + LIGHT + MLINE + MULTILEADER + MLEADERSTYLE + MTEXT + OLEFRAME + OLE2FRAME + POINT + POLYLINE + REGION + SECTION + SEQEND + SHAPE + SPLINE + SUBDIVISION + SUN + SURFACE + TABLE + TOLERANCE + TRACE + UNDERLAY + VERTEX + VIEWPORT + WIPEOUT ### 使用： #### 1. 创建一个新的dxf文件 ```java import com.bjak.dxfreduce.DxfDocWriter; import com.bjak.dxfreduce.entity.DxfCircle; public class TestCreateDxf { public static void main(String[] args) { Random random = new Random(); try (DxfDocWriter dxfDocWriter = new DxfDocument()) { for (int i = 0; i < 50; i++) { Color randomColor = new Color(random.nextInt(255), random.nextInt(255), random.nextInt(255)); LineWidth lineWidth = LineWidth.values()[random.nextInt(LineWidth.values().length)]; Vector3 center = new Vector3(200 + i * 100, random.nextInt(200), 100); // 添加圆形 DxfCircle dxfCircle = new Circle(center, 50); // 设置线宽 dxfCircle.setLineWidth(lineWidth); // 设置颜色 dxfCircle.setColor(randomColor); // 设置是否进行填充 dxfCircle.setSolid(i % 3 == 0); // 设置填充的颜色 dxfCircle.setSolidColor(new Color(random.nextInt(255), random.nextInt(255), random.nextInt(255))); // 添加图元 dxfDocWriter.addEntity(dxfCircle); // 添加线段 DxfLine dxfLine = new Line(new Vector3(2600, 1000, 100), center); dxfLine.setColor(randomColor); dxfLine.setLineWidth(lineWidth); dxfDocWriter.addEntity(dxfLine); // 添加多线段 DxfLwPolyLine dxfLwPolyLine = new LwPolyLine(); // 添加多线段各个顶点 dxfLwPolyLine.addPoint(new Vector2(i * 100, 1200)); dxfLwPolyLine.addPoint(new Vector2(50 + i * 100, 1200)); dxfLwPolyLine.addPoint(new Vector2(60 + i * 100, 1200 - 50)); dxfLwPolyLine.addPoint(new Vector2(10 + i * 100, 1200 - 50)); // 设置是否是闭合图形 dxfLwPolyLine.setClose(i % 5 != 0); dxfLwPolyLine.setLineWidth(lineWidth); dxfLwPolyLine.setColor(randomColor); dxfDocWriter.addEntity(dxfLwPolyLine); // 添加文字 DxfText dxfText = new Text(); dxfText.setText((char) (65 + random.nextInt(26)) + "哈哈"); // 设置旋转角度 dxfText.setAngle(random.nextInt(360)); // 设置高度 dxfText.setHigh(10 + random.nextInt(10)); // 设置倾斜角度 dxfText.setInclination(random.nextInt(45)); // 设置宽度 dxfText.setWidth(1 + random.nextInt(2)); dxfText.setColor(randomColor); // 设置绘制点位置 dxfText.setStartPoint(new Vector3(i * 100, 1400, 100)); dxfDocWriter.addEntity(dxfText); // 添加弧形 DxfArc dxfArc = new Arc(); dxfArc.setCenter(new Vector3(200 + i * 100, 1600, 100)); dxfArc.setRadius(100); dxfArc.setStartAngle(random.nextInt(90)); dxfArc.setEndAngle(180 + random.nextInt(180)); dxfArc.setColor(randomColor); dxfArc.setLineWidth(lineWidth); dxfArc.setSolid(i % 5 == 0); dxfDocWriter.addEntity(dxfArc); } String generateNewDxf = "E:\\testDxf\\test_empty_generate.dxf"; String entitiesFilePath = "E:\\testDxf\\test_empty_generate_entities.dxf"; // 保存dxf文件 dxfDocWriter.save(generateNewDxf, true); // 仅仅保存图元信息 dxfDocWriter.saveEntities(entitiesFilePath, true); } catch (IOException e) { e.printStackTrace(); } } } ``` #### 2. 加载一个已经存在的文件 ```java import com.bjak.dxfreduce.DxfDocWriter; public class TestCreateDxf { public static void main(String[] args) { try (DxfDocWriter dxfDocWriter = new DxfDocument(path)) { // body code, same as before code } catch (IOException e) { e.printStackTrace(); } } } ``` #### 3. 存储的dxf文件示例  ### 4. Version Change logs + 1.0 - 基础功能，图元的添加和导出 + 1.1 - 解决autoCAD2010和2016不兼容问题 - 添加一些注释 ### License Copyright (C) Akxy, Dxf reduce Project Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
