I am processing images, mostly TIFF Group 4, from a repository, and outputting them as PDF. The images *always* come to me in a byte array, never as a file. In fact, I've no option to get it as a file. The repository may or may not be local--it's accessed through its own API.
I would like to convert this buffer directly to a PDImageXObject, but both the CCITTFactory.createFromRandomAccess() are deprecated. Why? Looking at the source for the CCITTFactory class, they do the same thing as the createFromFile() methods, which first create a RandomAccessFile before calling createFromRandomAccessImpl(). Outside of this project, I've tried CCITTFactory.createFromFile() and seen that it is significantly faster than creating a BufferedImage and calling CCITTFactory.createFromImage(). Possibly it's fast enough to take the hit of writing the TIFF byte array to a temporary file, but why take the hit? So, why are CCITTFactory.createFromRandomAccess() are deprecated? -- "Hell hath no limits, nor is circumscrib'd In one self-place; but where we are is hell, And where hell is, there must we ever be" --Christopher Marlowe, *Doctor Faustus* (v. 121-24)
