patterns: Added Xilinx boot images (#210 )

* Adds pattern for Xilinx's Zynq UltraScale+ Boot Image format. * Boot images are generated by Xilinx's `bootgen` tool. * Spec: Xilinx UG1283 https://docs.xilinx.com/r/en-US/ug1283-bootgen-user-guide/Zynq-UltraScale-MPSoC-Boot-and-Configuration * Add test file generated as follows - Build bootgen tool from https://github.com/Xilinx/bootgen - Create dummy data with `dd if=/dev/zero of=image.bin count=1` - Create bif with `echo "img: {image.bin}" >image.bif` - Create test bin with `./bootgen -arch zynqmp -image image.bif -o xilinx_bootgen.hexpat.bin`

Benjamin Gilbert	917b05a9f2	patterns: Add DICOM (#162 ) DICOM files specify a "transfer syntax" which defines the image compression format, the encoding rules for the entire file, and any special-case encoding rules for particular fields. Many transfer syntaxes have common design features, but a transfer syntax is allowed to use completely custom encoding rules, and need not be publicly documented. Explicitly reject transfer syntaxes we know we don't support: implicit VR (uncommon), explicit VR big-endian (deprecated), deflate-compressed. In all other cases, follow some general rules and hope it works out. The large lookup functions were generated by a script, but I haven't included the code here, since its input is hand-massaged data copied from HTML tables. Add a JPEG WSI test case from the WG26 2021 hackathon (CC0 license) and a synthetic LE Explicit VLP case produced with img2dcm.	2023-09-26 16:51:02 +02:00

Benjamin Gilbert	7ecd6d87dd	patterns/tiff: Support BigTIFF and tiled TIFF; bugfixes and cleanups (#159 ) * patterns/tiff: show TIFF tag name/number in DirectoryEntry array Don't require unfolding the array entry to see what tag it contains. * patterns/tiff: show IFD number in IFD list * patterns/tiff: add JPEGTables tag; correct name of ICC Profile tag * patterns/tiff: add TIFFRational type Rationals, uniquely, are primitives with two fields. Add a struct to represent this, rather than inlining them. * patterns/tiff: use correct types for fields smaller than 4 bytes Small fields are always left-aligned in the 4-byte Value Offset. On little-endian TIFFs we currently cheat this by declaring a 32-bit value and letting little-endianness handle the semantics. However, this adds some extra conditionals, and misrepresents the resulting field as 32 bits. Drop the cheat. * patterns/tiff: add ValueOffset abstraction We were using the field type to make assumptions about whether the Value Offset is a Value or an Offset, which is incorrect. If the Count multiplied by the field size is larger than 4, the field is an Offset; otherwise it's a Value. Add display sugar for single-element arrays to avoid extra nesting. * patterns/tiff: drop dead code get_ifds_offsets() and BIG/LITTLE aren't used at all. get_total_IFDs() is only used for declaring the length of TIFFFile.IFDs, and isn't needed because IFDs are structured as a linked list. * patterns/tiff: drop set_endian() The call in TIFFFile is redundant. Drop both calls and open-code the check at the top level, before executing any code. The BigTIFF check will eventually be added alongside this one. Fail if we don't recognize the magic number. * patterns/tiff: minor cleanups * patterns/tiff: drop strip offset/byte count arrays from struct IFD They're redundant with the fields in the DirectoryEntry array. Also they're buggy: they assume the field Value Offsets are always offsets, which isn't true for single-strip IFDs, and they ignore a partial last strip in multiple-strip IFDs. * patterns/tiff: rewrite strip array generation We're making extra work for ourselves by avoiding the type system. Also, by calculating the number of strips we expect rather than the number of strips we actually have, we're miscounting and omitting any partial last strip. Instead, read the strip offsets and byte counts directly from the IFDEntry array. * patterns/tiff: add ImageData array for tiled IFDs * patterns/tiff: increase variable widths for BigTIFF Use 64-bit temporary variables for values that can be 64 bits in BigTIFF. * patterns/tiff: support BigTIFF * tests/patterns/test_data: add more TIFF tests	2023-09-24 20:04:20 +02:00
