This color select dialog is similar to the default one, but has more possibilities:

• All components of rgb and hls are shown.
• You can change any component of rgb/hls in a color gradient
• This component is shown depending of the other two as well as independent
• You can change the other two components in a two-dimensional gradient
• This one is drawn depending on the first component
• Additional you can enable a list of colors to change

This package consists of three parts working together:
The HTML Parser parses a html page using a language similar to html itself. Therefore you can just copy the html site you want to parse and mark the important things to get a template for the parser. With this template you can extract the marked information from any similar page. (imagine for example you have a site showing several entries from a database. Then you can create a template for one of those entries and the parser will automatically retrieve all entries)
The http-wrapper enables you to switch dynamically between Wininet (default library installed on every Windows computer) and Synapse (platform-independent, but not always installed).
The auto update class can be used to add an auto update function to a program which will check online for a more recent version, download that version automatically and (optionally) install it.

• Parser:
• Templates can be easily created/updated from the existing html file
• Can read all parts of the html file (except comments)
• The values are automatically converted into the correct output encoding
• The template languages allows the use of regular expressions
• The language allows optional elements, loops and conditions
• HTTP-Wrapper:
• Can be used for get/post transmissions over http and https
• Either uses the default Windows library Wininet or the platform independent synapse package
• Auto update:
• Uses a xml format to store the most recent version and a changelog on the server.
• Supports different updates for 32/64-bit platforms and linux,Windows or BSD systems
• Checks if a new version is available without downloading the whole, large changelog
• Allows the execution of an arbitrary command line after the update

This diagram drawing unit follows a model/view concept like qt: There is a view component responsible for showing the data, and a model class storing them.
This is much more flexible than the traditional way, where the data is handled within the viewing class.
Features:

• Model/view-concept with automatical synchronisation between different views showing the same model
• Filling with horizontal/vertical color gradient and different line/point-styles
• Interpolation using linear lines or splines
• The diagram data can be modified by the user if wanted
• Multiple axis and point rows as well as a legend naming the latter
• Automatical calculation of the view range and support for floats
• Standardmodels with lists of points, cyclic lists, and a model to merge other ones
• There is a help file

You can draw in a non vcl as if you would be able to use the normal Delphi, when you use this units. They contain a methode as replacement for every TCanvas methode.
The most important features are:

• Functions for drawing texts, ellipses, lines, rectangles and polygones.
• Functions for copying parts of pictures.
• Classes for setting font, pen and brush properties.
• A hash class and a ressources manager.

In some field they are even better than the Delphi functions, for example they can draw rotated text.
There is a good, German help, and you could use the documentation of TCanvas from Delphi.

These units consist of function which you need very often, when programming in FPC. You can use it to

• Automatical translation of with tr['marked strings'] and components
• insert and remove array elements, invert arrays
• execute a function in another thread.
• compare pchar/strings in different ways
• split strings, change encoding, load/save strings
• calculate Bernoulli statistics

You can use this unit to read a Unified Diff, do some work on its tree structure and save it finally.

• Reads Unified Diffs of one or many files
• Creates valid diffs
• Has functions to remove unnecessary data (see also Simplify Diff)

These are the most important features of TCvirus:

• It gives a canvas for direct drawing on the screen.
• It can mirror the screen.
• It returns handle of important objects like the task button, the task list, and the desktop.
• It can hide your program from the task manager.
• It can open and close the CD door.

Because TCvirus has originally been a component, there are 2 units, a component for the VCL and a unit for non VCL.

This is a command line parser working with Delphi as well as with Free Pascal (not tested under Linux).
In contrast to most of the other command line parsers, here you have to declare the allowed parameter, so the parser can be more intelligent.
The exact features are:

• type conversion
• automatically user notification about wrong parameters
• linux and windows style parameters
• different input possibilities for boolean flags
• understanding of quotation marks
• existing files with names containing spaces can be parsed without quotation marks

This allows an automatical update about the internt.
To use the class you need a wininet unit containing the windows internet functions (above is a new class which use a better customizable xml format).
Features:

• check for new versions
• download them in a compressed zip archive
• extract this
• replace the current executable with the new one on every Windows
• detect missing access rights on Windows NT...

This is a small browser based on the IE.
It is completely useless for a normal user, but you can use it to implement a browser for a certain web page in your program. The appearance and behaviour can be controlled over command line switches, so it allows, for example restricted access.

This unit can (de-)compress strings with using the huffman algorithm. In a compressed string a character isn't stored with 8 bit, but the bit count is different.
It is also possible to compress strings in the Unicode Format, arrays and files. These types are simply regarded as Ansi Strings.
This unit doesn't need the VCL.
You get the best compression rates in data which contains many equal characters, but it is always worse than modern compression processes like ACE or RAR.
