    Constraints and Limitations

    While Glasswall Conform is a powerful tool, certain constraints and limitations should be considered:

    • Image Handling: Some image colour spaces are unsupported and may be ignored. Additionally, image processing may convert compressed images to a lossless format, which can increase file size.

    • Font Handling: Glasswall Conform supports Base 14 and many Microsoft fonts, but unsupported custom fonts are replaced to mitigate potential risks.

    • PDF Structure: PDFs missing essential structural elements (e.g., root catalog, cross-reference tables) may not be recoverable.

    • Memory Usage: PDFs with many images may consume significant memory. While the tool has been tested with files up to 50 MB, larger files may experience performance issues.

    • Color Spaces: The CalRGB colour space is not supported.

    • Graphics Handling: Support for complex graphics, such as shapes, charts, and graphs, is limited. This version prioritises text integrity.

    • Document Recovery: Severely corrupted PDFs or those with missing structural elements may be unrecoverable.

    • Blocked Content Items: Malformed PDF files containing Content Items blocked by policy may reach the end user because Conform might remove the blocked Content Items before processing by the Engine.
