Aurelia Molzer 36a16db659 Merge pull request #285 from image-rs/read-into-buffer 
Read into byte buffer
 2025-07-25 19:16:09 +00:00
A. Molzer 48d52bed9b Return buffer layout as a struct 
Prepares extensibility for the eventual case of supporting multi-planar
image layouts that are to be written into a multi-planar buffer as
indicated by the caller in some way (possibly not via read_*_bytes but a
method taking a wrapper around the output buffer instead). Through the
struct we can later add an indicator that can be used by the caller to
decide between methods of fetching the pixel data as appropriate.

A. Molzer e62cdfbf42 Merge TagReader and exposed IfdReader internals 
Having the value reader itself take care of the bigtiff and limit
semantics is a little cleaner, with the TagReader being responsible
for the interface of grabbing specific types of IFD values.

A. Molzer 98cd3dc2d2 Refactor directory reading 
This allows us to recombine the reader and other file data in a Decoder
with any IFD, whether that of an image or an extension IFD as indicated
by an IFD pointer such as Exif and GPS.
