我在黑莓操作系统 7 上生成 EAN 13 条码时遇到了一些问题我实际上已经创建了一些代码来生成 EAN 13 并且它在模拟器 9800 os 6 上工作正常但是当我在模拟器 9900 dakota os 7 上时,条码全黑了有人可以请帮我解决我的问题
这是我的代码
public void ean13writer(String ang){
try {
EAN13Writer ean13 = new EAN13Writer();
ByteMatrix barcode = ean13.encode( ang , BarcodeFormat.EAN_13 , width , height );
System.out.println("barcode : "+barcode);
jajal= ByteMatrix2Bitmap(barcode);
VerticalFieldManager cardcodemanager = new VerticalFieldManager(){
};
Bitmap borderBitmap = Bitmap.getBitmapResource("rounded-border.png");
BitmapField cardcode = new BitmapField(jajal);
cardcodemanager.add(cardcode);
cardcodemanager.setMargin(2, 40, 2, 40);
cardcodemanager.setPadding(2, 10, 2, 10);
cardcodemanager.setBorder(
BorderFactory.createBitmapBorder(
new XYEdges(12,12,12,12), borderBitmap
)
);
cardScreen.add(cardcodemanager);
}catch (Exception e) {
//add( new RichTextField( "gagal coy : " + e ) );
String a = String.valueOf(e).toString();
Dialog.alert(a);
}
}
private static Bitmap ByteMatrix2Bitmap(ByteMatrix matrix){
int width = matrix.getWidth();
int height = matrix.getHeight();
//matrix is a 0-1 matrix
byte[][] array = matrix.getArray();
int[] imgdata = new int[width*height];
Bitmap bitmap = new Bitmap(width, height);
//System.out.println("hasil array byte [] [] ="+matrix.getArray());
for (int y = 0; y < height; y++) {
for (int x = 0; x< width; x++){
if (array[y][x] == 0){
imgdata[y * width + x] = Bitmap.TRUE_WHITE;
//System.out.println("KALO 0 = "+imgdata[y * width + x]);
}else{
imgdata[y * width + x] = Bitmap.TRUE_BLACK;
//System.out.println("KALO BUKAN = "+imgdata[y * width + x]);
}
}
}
bitmap.setARGB(imgdata, 0, width, 0, 0, width, height);
Bitmap retmap = new Bitmap(2*width ,10*height );
bitmap.scaleInto(retmap, Bitmap.FILTER_BILINEAR, Bitmap.SCALE_TO_FIT);
return retmap;
}
