数据的读取部分如下：

 

 

try
                {
                    InputStream inData = getClass().getResourceAsStream(strImg);
                    DataInputStream in = new DataInputStream(inData);
                    in.skipBytes(nResPos[3][0]);
                    //读入数据

                    //short nSize=in.readShort();

                    for (int i = 0; i < nImgCount.length; i++)
                    {
                        //int nSkip=i+1
                        if (nImgCount[i] > 0 && drawImg[i] == null)
                        {
                            short nb = in.readShort();
                            byte[] data = new byte[nb];
                            in.read(data);
                            drawImg[i] = Image.createImage(data, 0, nb);

                            // switch(i){

                            //     case 156:

                            //     case 176:

                            //     case 179:

                            //     case 180:

                            // }

                            {

                            }
                        } else if (i + 1 < nImgCount.length)
                            in.skipBytes(nResPos[3][i + 1] - nResPos[3][i]);
                    }
                    //清除载入进度条

                    if (nLoadPecent >= 0 && bDrawLoad && !BIsLoading)
                    {
                        nLoadPecent = -1;
                        // nStatus = nOldStatus;

                        // initLoading = false;

                        // update();

                    }

                    in.close();
                } catch (Exception e)
                {
