I'm using TImageEnProc.AdjustLevels procedure to change midtone levels. All TImageEnProc.AdjustLevels procedure works like Photoshop tonal range function except when I want to change midtone levels. For example: if I set in ImageEN MidTone = 64 to simulate the Photoshop MidTone 1.97, the ImageEN result is lighter than Photoshop result. And when I set in ImageEN Midtone = 192 to simulate Photoshop Midtone 0.40, the ImageEN result is darker than Photoshopo result.
Why this? The results of both software should be identical...
