PEF to MMD Quality Analysis

Color accuracy is a priority in this conversion. Color profiles (sRGB, Adobe RGB, etc.) are preserved when both formats support them. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. Mermaid Diagram preserves all data losslessly, so output size depends on the content's inherent compressibility. Use ```mermaid blocks in GitHub README for inline diagrams For the best results, start with the highest quality PEF Raw Photo source file available.

This is a cross-category conversion from Image (PEF Raw Photo) to Diagram (Mermaid Diagram). While these formats serve different purposes, Xonvert extracts the compatible data from your PEF Raw Photo source and maps it into the Mermaid Diagram format. Image files typically contain Pentax camera users and RAW photography processing, while Diagram files are used for GitHub documentation. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.

The PEF to MMD conversion applies format-appropriate algorithms to ensure maximum data fidelity. Contains 12-bit or 14-bit uncompressed sensor data
