DCT Visualizer

How to Use
The two panels (DCT Matrix and Image views) above represent 8x8 matrices. The one on the left is a DCT matrix with values running from -1024 to 1023, while the one on the right represents the image, with values running from 0 to 255. You can change the value of any square by hovering your cursor over the square and doing any of the following:

• Scroll your mouse wheel
• Left click to max out value
• Right click to bring value to minimum
• Middle click to "center" value

You can also click the full image on the left Pixel Picker panel, which will update the Image View with the pixels selected. This project is a fork of the DCT Visualizer built by 0612 @ Nerdfirst. Credit to his excellent work!
