From 8bdd350555265f86f8a9f031e486fdca30062aac Mon Sep 17 00:00:00 2001 From: Roo Code Date: Mon, 30 Jun 2025 08:59:10 +0000 Subject: [PATCH] Fixes #5169: Add image reading support to read_file tool - Extended FileResult interface to include imageData and mimeType fields - Added helper functions for image detection, MIME type mapping, and base64 conversion - Implemented size validation (10MB limit) to prevent memory issues - Added support for PNG, JPG, JPEG, WebP, GIF, BMP, ICO, TIFF, SVG formats - Created comprehensive test suite covering all image formats and edge cases - Images are now converted to base64 and included in XML output with metadata --- .../__tests__/readFileTool.image.spec.ts | 281 ++++++++++++++++++ src/core/tools/readFileTool.ts | 93 ++++++ 2 files changed, 374
