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
patterns/id3: Fix the error No variable named 'n' found. (#160 )

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

jfsbrito	13b97fc976	patterns/7z: Added 7Zip pattern (#128 ) * 7z.hexpat This repository contains a custom pattern for the ImHex tool that enables the analysis of 7zip files. The pattern allows for a structured view of 7zip files within ImHex, providing insights into various aspects of the file structure. - Identification of 7zip files: The custom pattern detects and identifies 7zip file types based on their signature. - Extraction of key information: The pattern extracts important details from the 7zip file, such as the format version, CRC values, relative offset of the end header, and file size. - Differentiation of compression methods: The pattern distinguishes between LZMA and LZMA2 compression methods used within the 7zip file. - Visualization of start and end headers: The pattern helps in visualizing the start and end headers of the 7zip file, making it easier to navigate through its structure. To use the custom pattern for analyzing 7zip files in ImHex, follow these steps: 1. Install ImHex: Ensure that you have ImHex installed on your system. 2. Open a 7zip file: Launch ImHex and open the 7zip file you want to analyze. 3. Apply the custom pattern: In the "Pattern" menu, select the custom pattern for 7zip file analysis and apply it. 4. Explore the file structure: ImHex will display the matched patterns, allowing you to explore the structure of the 7zip file with the extracted information. Please note that this custom pattern is designed specifically for 7zip files and may not be suitable for other file formats. Contributions to this custom pattern for 7zip file analysis are welcome. If you have any improvements, bug fixes, or suggestions, feel free to submit a pull request. This custom pattern for ImHex is licensed under the [MIT License](LICENSE.md). You are free to modify and distribute this pattern as per the terms of the license. We would like to acknowledge the developers of ImHex for providing an excellent tool for binary file analysis. The custom pattern for 7zip file analysis in this repository builds upon the capabilities of ImHex to enhance the understanding of 7zip file structures. --- We hope you find this custom pattern useful for analyzing 7zip files using ImHex. If you encounter any issues or have any questions, please feel free to raise them in the "Issues" section of this repository. Thanks! * Added test file ---------	2023-06-19 23:08:42 +02:00
