How to use Convert JPG to RGB
- 1. Add the JPG to dump. Drop in the photo whose raw pixel data you want as plain numbers, such as a small test image or an icon you are debugging.
- 2. Set the value formatting. Type a Value separator such as a space or comma to place between each red, green and blue number, and toggle One pixel per line to put each pixel on its own line instead of one long stream.
- 3. Copy the RGB values. The tool outputs every pixel's red, green and blue values in order, formatted the way you chose. Copy the result into a script, spreadsheet or shader you are building.
When to use Convert JPG to RGB
Convert JPG to RGB dumps the raw red, green and blue values of every pixel in a photo as plain text. It is aimed at developers who need actual numeric pixel data to feed into a script, a shader or a manual calculation rather than a viewable image.
- Feeding pixel data into a shader or graphics program. You are writing a custom rendering routine and need the exact RGB values of a small test texture as literal numbers. Dumping them with one pixel per line gives you data ready to paste into code.
- Debugging a color processing algorithm. Your image processing code is producing unexpected output and you want to verify the raw input values by hand. Extracting the RGB array lets you check specific pixels against your expectations.
- Building a tiny test fixture from a real photo. You want unit test data based on an actual image rather than made-up numbers. Dumping a small photo's RGB values with a comma separator gives you a fixture you can paste directly into test code.
- Analyzing pixel patterns in a spreadsheet. You want to chart or sort pixel color values from a small image in a spreadsheet application. Formatting the output with one pixel per line makes it easy to paste into rows.
