My curves tool

Curves tool in action


This is my curves tool. Inspired by the curves tool in Photoshop and Gimp. It keeps a list of presets which is located in a folder “curves” in the application folder. All files in this folder is .ACV files which is standard Adobe curve files. When you add a curve to the preset it saves the curve to the “curves” folder.

This project was updated 02.04.2015. When clicking outside the grid, or at an horizontal value where it already exists a point, it would give an error. This has now been corrected.

Hope you find this tool useful.

This is just a demo and not a complete application I think of it as a curves preview dialog.

Adjust brightness, contrast and saturation ++

Adjust image demo

I have just uploaded a small demo of how to adjust brightness, contrast and saturation of an image. There are also two other usefull samples included in the demo. One is the auto adjustment setting (using histogram stretching) the other one is an exposure control, perfect for adjusting (lighten) dark pictures.

Hope you find it usefull and if you have some better ideas why not share em. These routines are based on a combination of my own and others ideas and source code.
