I want to add a feature to my software that will allow users to grayscale most of a photo and keep just one object in ites original color, or vise-versa.
Click anywhere within the area of color the user want to convert to grayscale and with a click,
change to grayscale. Or the reverse, you select the color you want to keep and turn the rest into grayscale There must be a trackbar to to help them see how much of the area is selected and adjust it as required before applying the grayscale so that it does not affect other color areas.
See the sample images I found on internet.
Make a Delphi XE2 project. Use native components and or ImageEn components.
Do not put any controls on panels. Only use the the minimum non functional components.
