A. Molzer 61867b46f9 Make decoder's Image an option 
Instead all methods with mutable self will initialize it on-demand.
There are only few methods that take `&self` and can not do that. For
those that have no error/option return we panic but both of these could
panic previously already. This should be fine by documentation alone. In
particular, the image size can be queried safely.

A. Molzer 6b04bff6b2 Relax Decoder, new interface documentation 
The bounds `Read + Seek` are not representational so we may remove them
from the struct itself. This also allows us to use more precise bounds
for direct access to the inner stream, especially were that does not
seek.

Groups operations according to their use case.

A. Molzer bd0dccef3a Deprecate Decoder::*tag methods 
Funnel users towards the `IfdDecoder` instead. That type does not have
a generic over the underlying reader. It also works with a directory of
your own choosing. So the duplicates that should go are those directly
on the decoder.

A. Molzer 7491436306 Utils for DecodingBuffer et.al 
Most of this is slightly gratuitous for now, we have no need internally,
but especially since the enums are non-exhaustive it will probably be
appreciated that you can interact with the buffer at a byte-level.

Additionally we make the extra promise that all sample types correspond
to some supported SampleType tag value. This prepares using the same
buffer for a runtime version of `Encoder::write_image`.

A. Molzer 14ebf376f3 Move Directory from image into decoder proper 
This prepares allowing to iterate over a TIFF file with invalid images
while `Image` maintains invariants. For instance we precalculate the
amount of buffer space and verify that the count of strips makes sense
in the constructor—so we do not have to redo that for every other entry
point.

A. Molzer 45cd3c3b63 Improve unexpected tile count error 
Do we even want to error early here? This isn't exactly fatal to reading
the image it is a only nuisance. It becomes crucial only when we are at
the point of reading all the tiles themselves.
 2026-02-14 06:55:29 +01:00
A. Molzer 701fcc46b8 Add libtiffpic test suite 
Two tests are disabled, both related to tiles, since they do not follow
the fully released spec themselves but incidentally decode with libtiff
anyways. The two images (`cramps-tile.tif`, `quad-tile.tif`) are tiled
layout which libtiff detects by the presence of TileWidth/TileHeight
tags. We would detect that by chunks encoded via TileOffsets and
TileByteLengths tags. However the images encoded their chunk data into
the StripOffsets tag; additionally they contain a RowsPerStrip value
anyways.

Tests disabled as this is to be resolved in a separate issue (#338) with
a decision on treatment of this situation (strictness setting or copying
libtiff, also error late for mismatched lengths).

A. Molzer 9a23090b6e Provide write_entry_bytes 
This complements the entry API of the encoder with the byte slice based
method. Note we don't provide it for writing raw data, here a
`std::io::Write` would be more appropriate and we should not attempt to
make it `write_all`, nor compress. You'd get all the benefits of the
other API through `[u8]: TiffValue` since that interface is otherwise
type agnostic and `u8` specifically is endian agnostic.

A. Molzer 9d409433e8 Rename write_tag_value to write_tag_buf 
We have not released this yet, let's align these names before it is too
late. The decoder adopted the `_buf` suffix and I find it more
convincing than the more generic `_value` (that also confusingly shares
it with `TiffValue`).
