 1 | # String2Bitmap
 2 | 将文字生成图片的Utils
 3 | 
 4 |       bitmapToByteArrayForPrinter方法
 5 |       
 6 |       该方法比较容易理解：
 7 |       
 8 |           1.方法参数是待打印的文字的List集合，其中存放的就是一行行待打印的文字
 9 |           2.读入参数后，先配置生成图片的宽度[为8的倍数]，然后把每一行文字读入计，并计算这一行是否可以完全显示，如果不能一行显示需要多少行
10 |           3.设置文字的大小高度并计算一行文字的高度
11 |           4.生成空的位图
12 |           5.开始遍历List集合，绘制每一行
13 |           6.返回生成的图片
14 |       
15 |       对于图片的合并，这个比文字生成图片更简单一点：
16 |       
17 |           1.取出两张位图，把最宽的设置为宽度，高度之和设置为生成图片的高度
18 | 
19 |               int width = Math.max(first.getWidth(), second.getWidth());
20 |               int height = first.getHeight() + second.getHeight();
21 | 
22 |           2.这里比较麻烦的就是 logo的位置必须居中显示，所以我们需要把logo绘制的起点改变一下
23 | 
24 |               int startWidth = (width - first.getWidth()) / 2;
25 | 
26 |           3.绘制即可
27 | 
28 |               Bitmap result = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565);
29 |               Canvas canvas = new Canvas(result);
30 |               canvas.drawBitmap(first, startWidth, 0, null);
31 |               canvas.drawBitmap(second, 0, first.getHeight(), null);
32 |       
33 |       原本List集合是文字，在List集合泛型的时候，不能在单纯的传入一个字段了，而是携带信息的参数
34 |       
35 | 				   /**
36 | 				     * @param text           等待打印的字段
37 | 				     * @param isRightOrLeft  可空，默认右边
38 | 				     * @param isSmallOrLarge 可空，默认小字
39 | 				     */
40 | 				    public StringBitmapParameter(String text, int isRightOrLeft, int isSmallOrLarge) {
41 | 				        this.text = text;
42 | 				        this.isRightOrLeft = isRightOrLeft;
43 | 				        this.isSmallOrLarge = isSmallOrLarge;
44 | 				    }
45 | 			 在把文字构建图片的时候，由于是List存储的既是一行，所以我们这样做可以把每一行设置成左便开始打印还是右边，文字设置为大还是小，但是不能把文字的字体样式修改了
46 | 			 	 for (StringBitmapParameter mParameter : mBreakString) {
47 | 			            String str = mParameter.getText();
48 | 
49 | 			            if (mParameter.getIsSmallOrLarge() == IS_SMALL) {
50 | 			                paint.setTextSize(SMALL_TEXT);
51 | 			            } else if (mParameter.getIsSmallOrLarge() == IS_LARGE) {
52 | 			                paint.setTextSize(LARGE_TEXT);
53 | 			            }
54 | 
55 | 			            if (mParameter.getIsRightOrLeft() == IS_RIGHT) {
56 | 			                x = WIDTH - paint.measureText(str);
57 | 			            } else if (mParameter.getIsRightOrLeft() == IS_LEFT) {
58 | 			                x = START_LEFT;
59 | 			            } else if (mParameter.getIsRightOrLeft() == IS_CENTER) {
60 | 			                x = (WIDTH - paint.measureText(str)) / 2.0f;
61 | 			            }
62 | 
63 | 			            if (str.isEmpty() | str.contains("\n") | mParameter.getIsSmallOrLarge() == IS_LARGE) {
64 | 			                canvas.drawText(str, x, y + FontHeight / 2, paint);
65 | 			                y = y + FontHeight;
66 | 			            } else {
67 | 			                canvas.drawText(str, x, y, paint);
68 | 			            }
69 | 			            y = y + FontHeight;
70 | 			        }
71 |               
72 | 			 这里展示的即是关键位置
73 | 			 在图片的压缩这一部分，之前是ARGB_8888的，现在修改为了RGB_565，基本占内存小了一半，前者一个像素32位，后则16位，还有个模式是ALPHA_8仅仅有8位，但是这个模式下，打印出来的是纯黑的玩意，他只有透明度，没有颜色，所以不行，打印的时候也是把它变成黑白的打印的，而且这应该是压缩的极致了
74 | 			 现在就是合并图片生成的太慢，我觉得是我这里导致的：
75 |        
76 | 			   for (int i = 0; i < result.getWidth(); i++) {
77 | 		            for (int j = 0; j < result.getHeight(); j++) {
78 | 		                result.setPixel(i, j, Color.WHITE);
79 | 		            }
80 | 		        }
81 |             
82 | 		     这个循环是为了把没个像素点都变成白的，然后再绘图，因为不这样做的话，图片打印出来，周边会有黑色条文，就是因为没有配色，他是透明的，所以打出来就是黑的导致的
83 | 		     所以如果把这个O(n^2)改变的话，就应该能加快生成图片的速度
