如何从Unity3D访问本地Java位图？

问题描述：

我想在我的Unity项目中使用加载在我的本地Java库中的位图。如何从Unity3D访问本地Java位图？

如何将位图从Java传递到C＃？

由于你不是很具体的问题，我只是假设你有你的图像加载为BufferedImage。所以这里有一个关于如何去做的建议：

使用JNA Library可以更好地访问c＃的资源。

，然后也许做一些与此类似：

BufferedImage someImage; 
long somePointer; 

DataBuffer data = someImage.getData().getDataBuffer(); 
int[] bankOffsets = data.getOffsets(); 
long offset = 0; 
com.sun.jna.Pointer ptr = new com.sun.jna.Pointer(somePointer); 
switch(data.getDataType()) { 
case DataBuffer.TYPE_BYTE: 
    byte[][] bbanks = ((DataBufferByte) data).getBankData(); 
    for (int i = 0; i < bbanks.length; i++, offset += bbanks[i].length - bankOffsets[i]) 
     ptr.write(offset, bbanks[i], bankOffsets[i], bbanks[i].length - bankOffsets[i]); 
break; 
case DataBuffer.TYPE_DOUBLE: 
    double[][] dbanks = ((DataBufferDouble) data).getBankData(); 
    for (int i = 0; i < dbanks.length; i++, offset += (dbanks[i].length - bankOffsets[i])*8) 
     ptr.write(offset, dbanks[i], bankOffsets[i], dbanks[i].length - bankOffsets[i]); 
break; 
case DataBuffer.TYPE_FLOAT: 
    float[][] fbanks = ((DataBufferFloat) data).getBankData(); 
    for (int i = 0; i < fbanks.length; i++, offset += (fbanks[i].length - bankOffsets[i])*4) 
     ptr.write(offset, fbanks[i], bankOffsets[i], fbanks[i].length - bankOffsets[i]); 
break; 
case DataBuffer.TYPE_INT: 
    int[][] ibanks = ((DataBufferInt) data).getBankData(); 
    for (int i = 0; i < ibanks.length; i++, offset += (ibanks[i].length - bankOffsets[i])*4) 
     ptr.write(offset, ibanks[i], bankOffsets[i], ibanks[i].length - bankOffsets[i]); 
break; 
case DataBuffer.TYPE_SHORT: 
    short[][] sbanks = ((DataBufferShort) data).getBankData(); 
    for (int i = 0; i < sbanks.length; i++, offset += (sbanks[i].length - bankOffsets[i])*2) 
     ptr.write(offset, sbanks[i], bankOffsets[i], sbanks[i].length - bankOffsets[i]); 
break; 
case DataBuffer.TYPE_USHORT: 
    short[][] usbanks = ((DataBufferUShort) data).getBankData(); 
    for (int i = 0; i < usbanks.length; i++, offset += (usbanks[i].length - bankOffsets[i])*2) 
     ptr.write(offset, usbanks[i], bankOffsets[i], usbanks[i].length - bankOffsets[i]); 
break; 
case DataBuffer.TYPE_UNDEFINED: 
    throw new IllegalArgumentException("Unsupported data type"); 
}

写应该是所有的像素颜色值数据。格式取决于图像类型（可以用getType()方法的类BufferedImage获得。

另外，您也可以使用Java本地接口，但我没有看过成。
