TJpgDec Integration

Overview

Use this skill to integrate TJpgDec by proving the input callback, output callback, work buffer, color format, scaling, and display path. TJpgDec is small, but it still needs careful ownership of input streams and pixel blocks.

When To Use

Use this skill when:

• The user wants JPEG decoding on MCUs, small displays, LVGL image pipelines, or resource-constrained embedded systems.
• The issue involves decode errors, wrong colors, cropped images, slow rendering, memory faults, or display block callbacks.
• The project stores JPEGs in flash, filesystem, SD card, OTA resources, or network streams.

Do not use this skill when the display driver itself is not proven. Use lvgl-integration, u8g2-integration, or epd-integration as appropriate.
