如何在Android中将位图保存到.tiff？

Question

I know it is possible to save bitmap to png or jpg

now i want to save bitmap to .tiff,anybody can help?

Answer 1

Android does not have native support for saving TIFF files.

You best bet would be to get the raw byte array, and then using either a Java or NDK library (like libtiff ) to save it as a TIFF.

Answer 2

I believe this is is a repost from here: Convert a bitmap image to an uncompressed tif image in Java

To answer the question, the above answer suggested the following using the Java Advanced Imaging (JAI) library:

TIFFImageWriterSpi spi = new TIFFImageWriterSpi();
ImageWriter writer = spi.createWriterInstance();
ImageWriteParam param = writer.getDefaultWriteParam();
param.setCompressionMode(ImageWriteParam.MODE_DISABLED);

ImageOutputStream ios = ImageIO.createImageOutputStream(new File("output.tif"));
writer.setOutput(ios);
writer.write(null, new IIOImage(bmp, null, null), param);

Answer 3

您始终可以将位图另存为.png并将其转换为.tiff

Answer 4

Android hasn't support for tiff images. You should use some library for working with tiff. For example my: https://github.com/Beyka/Android-TiffBitmapFactory
