Some of my experiments with delphi ;).

Steganography

Steganography is the art of writing in cipher, or in characters which are not intelligible except to persons who have the key.

This is an usable steganography application for concealing information in jpeg files by replacing the least significant bit of the RGB triplet with the provided text on a bit by bit basis. Since only the least significant bit is changed the resulting R, G, B bytes will be less than or more than unity resulting in a almost negligent amount of change in the color value.

Image Manipulation

An example of manipulating images in delphi
What it does ?

  • Fade in
  • Fade out
  • Grayscale
  • Negative
  • Alpha blending
  • RGB->BRG->GRB
  • Dithering
  • Brightness/Contrast

Pretty simple code!
Gives a nice intro to people wanting to understand image manipulation basics......
Just shows how easy thingys are with DELPHI :)!

Image2html

Have you ever thought of converting an image to HTML format ? This example shows you how to do it
The code provided also gives a basic understanding of IMAGE MANIPULATION. Graphics in DELPHI is so damn easy ..... and this proggy just shows that!

The basic idea is to load any image into a Timage and then check the type of image (jpeg, bmp, etc) and then convert the image to a Tbitmap for getting out the data. The data is then dumped into a file with some HTML tags so that it gives out color... and voila... you have converted your image to HTML
format....
Lot of improvisation is possible which i would be submitting in future versions (if i ever ;))

LCD Interfacing

This proggy shows how to interface ur parallel port with a LCD display.
What does it do?

  • You can see what you type from the keyboard on the LCD
  • Clear the LCD
  • Turn Off LCD display
  • Turn On LCD display
  • Cursor On
  • Cursor Off
  • Cursor Blink
  • Define your own font

This example basically shows how you can interface real world devices to the
computer by using the parallel port..
