Question

I’ve read the TIFF file specification provided by Adobe, but I couldn’t find any standards related to:

1. If it’s better/more accepted to put IFDs immediately following the image data they describe/immediately preceding the image data they describe/all together at the top with image data below/etc.

2. How many rows to put in each strip. Is there generally a good number? If it’s a multi-plane image, would it be okay to make each strip just hold all the rows in that particular image plane?

The reason I ask is because I’m programming some Java to make a TIFF file.

Answer 1

I think it doesn’t matter where you put the IFDs provided you follow the spec (because a TIFF reader/writer should be using the spec to find them).

When I wrote some TIFF files, I did:

1. TIFF file header
2. Tags for first page
3. Image for first page
4. Tags for second page
5. Image for second page
6. Etc.
