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.

Threaded thumbnails demo

5 Replies

Yet another thumbnails demo, this time showing how to make the thumbnails in a seperate thread. There is a small problem which I belive is caused by the Delphi jpeg unit which sometime will render a thumbnail empty. With empty I mean that it has the correct width and height but not the image itself but just a white rectangle. If you figure out how to fix it please tell me so I can fix it. It only happens once and awhile so it is not easy to pinpoint what is causing it.

This demo also fix some problems which was present in previus thumbnail demos so if you had problems with previus demos try this one.

Using a diffrent imagelib seems to solve the problem reagarding blank thumbnail. I strongly recomend ImageEn but also GraphicsEx is a good one.

You need rkView installed to run this demo. You find it under components.
