如何從Unity3D訪問本地Java位圖？

Question

我想在我的Unity項目中使用加載在我的本地Java庫中的位圖。

如何將位圖從Java傳遞到C＃？

由於你不是很具體的問題，我只是假設你有你的圖像加載爲BufferedImage。所以這裏有一個關於如何去做的建議：

使用JNA Library可以更好地訪問c＃的資源。

，然後也許做一些與此類似：

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"); 
} 

寫應該是所有的像素顏色值數據。格式取決於圖像類型（可以用getType()方法的類BufferedImage獲得。

另外，您也可以使用Java本地接口，但我沒有看過成。
