Multi Icon

Create stunning, high quality (256 x 256) multi-resolution icons (.ico) and "mainicon" resources (.res) with ease and reliability. Open an image from file, or paste one in with transparency, or drag and drop an image directly onto the corresponding icon resolutions, then save. The multi-resolution icon stores a 256 x 256 image in PNG format, and five images at 64 x 64, 48 x 48, 32 x 32, 24 x 24 and 16 x 16 in native Windows icon format for maximum compatibility, back to Windows 95. Use a single Master image for the complete set of images, or separately individualise each image resolution for complete control over appearance. Support for 32 bit images with 8 bit alpha mask, and built-in common mask shapes to instantly transform a basic, square image into an alpha-transparent shape with one click. Save as a multi-resolution icon in either the standard Windows icon (.ico) format, or as a Windows resource (.res) in the "mainicon" format.

Acrylic DNS Proxy

Acrylic is a local DNS proxy for Windows which improves the performance of your computer by caching the responses coming from your DNS servers and helps you fight unwanted ads through the use of a custom HOSTS file (optimized for handling hundreds of thousands of domain names) with support for wildcards and regular expressions. When you browse a web page a portion of the loading time is dedicated to name resolution while the rest is dedicated to the transfer of the web page contents. What Acrylic does is to reduce the time dedicated to name resolution for frequently visited addresses closest to zero possible. Furthermore Acrylic's sliding expiration caching mechanism and DNS silent updates are able to improve the browsing experience independently of the browser. With Acrylic you can also gracefully overcome downtimes of your DNS servers without disrupting your work, because in that case you will at least be able to connect to your favourite websites and to your email server.

SplashAbout

Every application should have a Splash screen and an About dialog. This component makes it as easy as dropping it onto your main form and calling a couple of methods. If you set VersionInfo in your Project Options, then most properties are automatically picked up. Two methods: SplashAbout1.ShowSplash (in form1.create method) and SplashAbout1.ShowAbout. No bloat: Windows are created on-the-fly and destroyed on close. OptionalIcon can be multi-resolution Set OptionalIconSize and the best available resolution/size will be displayed in Splash and About dialogs. Debug Logging available. Compile the /demo project to see what it can do Debug Logging (set DebugMode = TRUE) Windows and Linux.

Ant Movie Catalog

Manage your movie collection: User interface translated in about 30 languages. Can store catalog in two file format: its own binary format or XML. Import information from Internet (using scripts); by default it includes scripts for IMDB (US), DVDFR (FR), Allociné (FR) and lots of others. User-customizable links to do a search on movie websites. Information importation from various media files (audio & video codec, bitrates, resolution, framerate, size). Scripting technology, using Object Pascal language, allowing to modify catalog: Find & replace, moving field values, ... Printing, using customizable templates. Export to other formats: HTML (based on a template that you can modify or create yourself), SQL commands (to re-import data in a DBMS such as MySQL), CSV (text files, can be used as tables with Microsft Excel for example). Import from other formats: CSV (Microsoft Excel can create such files, but a plain text file can be used too), Microsoft Access and a few others.

Camera Digital Exif Info

“Camera Digital Exif Info” is a free info viewer, provides you to check your digital camera (most of the SLR) shutter count and basic EXIF info. There are various EXIF tools around of course, but cool GUI application and simplicity are always a plus. Shutter actuation is an important factor because it tells you the extent of wear the camera has undergone, and it’s particularly crucial when you are buying used cameras. Almost all new digital cameras use the EXIF annotation, storing information on the image such as shutter speed, exposure compensation, F-number, what metering system was used, if a flash was used, ISO number, date and time the image was taken, white balance, lenses that were used and resolution. All this Informations is usually embedded in the EXIF data of the picture files. This tool is available as a stand-alone Windows win32 executable and a Macintosh OS X package.

MixedCursorCollection

771,000 animated and static cursor schemes and cursors in red, green, blue, yellow, aqua, orange, purple, pink, white, grey, black, brown, rainbow, and custom color. This interactive archive contains a large number of multi-resolution (128 x 128 and 64 x 64) animated and static cursors that have been specially encoded using algorithmic techniques to pack ~771,000+ cursors / files and ~1.7 Tb (~118 Gb when the PNG format option is employed) of data into an ultra-compact app of ~2.2 Mb. Each individual cursor scheme and/or single cursor can be easily previewed with the dedicated built-in file viewer. A single cursor scheme - comprising of 17 cursors (".ani" or ".cur") and 1 installer script (".inf") - can be extracted to disk as a whole, or installed onto your computer for use with a predefined scheme name or a custom name of your choosing. In addition, a folder's content can be extracted to disk.

Spintax Studio

Spintax Studio is a native Windows editor for spintax templates: two panes, your template on the left, its live render on the right. Preview and the valid/invalid verdict come from the real spintax engine inside the application, not from a second parser. Diagnostics carry line and column positions and link to the built-in help; panels list variable definitions, references, session values and #include targets with their resolution status. Generate variants locally, reproduce them with a seed, and export as plain text, an XLSX workbook, or one file per variant. Offline by default: no account, no telemetry, no Node.js, PHP or Python runtime — one self-contained executable. Optional AI drafting is off until you turn it on and talks only to the endpoint you configure, with your own key when it needs one. Interface and built-in help in 14 languages. Free and open source, GPL-3.0-or-later. The SPINTAX language and its engine family are documented at spintax.net.
