ATShapeLine

ATShapeLine is a component which paints line (directions: left-right, up-down, diagonals), with or without arrows at both sides. Options: line width, line color, arrow size, arrow color, show arrows. It is Lazarus port of Delphi component TLine (renamed since TLine id is busy with TAChart).

MathParser

An expression parser and a virtual machine. A formula is compiled to a flat byte array and evaluated by a linear pass over it, with no allocation on the path of an ordinary formula. On x86-64 an optional accelerator compiles that bytecode to machine code and hands anything it declines back to the interpreter, so an answer is never fast but wrong. Results are cached by shape: once 2 + 3 has been compiled, 5 + 7 reuses the same script and only writes the numbers into a copy. 163 functions to call and 249 names in the table, your own functions and variables bound by address, symbolic differentiation. The Lazarus parser packages require FCL and define NOFORMS and NOGRAPHICS, so they install without LCL. WebAssembly uses a separate console configuration. Two units ask for more at their defaults, Thread through Application.HandleException and BlobManager through TGraphic; drop the defines and add the LCL to the package if you want them.

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.
