Hello Community ![]() Dunno if there is such a topic but didn't find it ![]() Furthermore my questions are the following: 1) How can I change the RGB values of the pixels? 2) If I need specialised programs to do it, which one would you suggest? Thank you all very much in advance ![]() Regards |

Hello occasus, It's very hard/impossible changing the rgb values of an image, especially when it's compressed (most image types are). I suggest you try and create your own program for this. Greets |

Thank you a lot but unfortunately I am very very bad in programming (I just can create a program that does a + b = ?). |

You can edit imagines with almost every kind of high level prog. language. C++, java, C#, C, VB and php too. All these will do what you need, in different ways, with different syntax and speed. Regards, sfabriz |

If you want to do it by programming I suggest you API from Image Magick ( ![]() Was very usefull for me for some stegano and programming challenges ![]() ![]() ImageMagickTM 6.0.8 is a robust collection of tools and libraries to read, write, and manipulate an image in many image formats (over 90 major formats) including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create images dynamically, making it suitable for Web applications. You can also resize, rotate, sharpen, color reduce, or add special effects to an image or image sequence and save your completed work in the same or differing image format. Image processing operations are available from the command line, or from the C, C++, Perl, Java, PHP, Python, or Ruby programming languages. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. ImageMagick's focus is on performance, minimizing bugs, and providing stable APIs and ABIs. |
