    HTML Parser alternative to MSHTML?

    Alexander Sviridenkov replied to Darian Miller's topic in Delphi Third-Party

    Why ypu don't you parser from HTML Component Library? AFAIR you own a license. Parser supports XPath and JQuery so searching for particular nodes is quite simple.

    awk-like processor using Delphi code?

    Alexander Sviridenkov replied to David Schwartz's topic in General Help

    HTML Component Library. Yes, it can display almost the same as browser (HTML4 and CSS3, except JS) but I was thinking about using its CSS part for calculating and applying rules.

    Alexander Sviridenkov replied to David Schwartz's topic in General Help

    HCL has very fast and universal CSS processor (separated from UI/rendering), maybe it can be used there.

    Alexander Sviridenkov replied to Alexander Sviridenkov's topic in Delphi Third-Party

    There is CSS contenteditable property which can be set to true or false using snandard CSS rules. Deleting of certain tags cannot be prohibited, but editor supports XML schema which can define rules for adding new tags (what tags are allowed and what tag can be added to another tag).

    Reading SVG code from text file

    When reading text file you should know (or determine) its encoding.

    AI experiences, GPT3 Leta series

    Alexander Sviridenkov replied to Rollo62's topic in Algorithms, Data Structures and Class Design

    In my country all mobile providers and banks use such AI, and all these AIs are so stupid that first thing that everyone do when calling is trying to force him to switch to human. Just another annoying thing like long voice menus.

    Custom text rendering

    Alexander Sviridenkov posted a topic in Delphi Third-Party

    Just made this for fun. Canvas for HTML library which uses no system text/font API. Everything is processed inside library. Fonts are loaded directly from TTF file/stream. Strings are converted into sequence of glyphs and transformed by various opentype features (kerming, glyph substitution/reposition, RTL, ligatures, etc.). After that glyphs are converted to graphics paths and rendered using D2D FillGeometry method. https://s9.gifyu.com/images/ownfont.gif

    Custom text rendering

    Alexander Sviridenkov replied to Alexander Sviridenkov's topic in Delphi Third-Party

    Yes, font class can read and write TTF and WOFF, and also extract font of any format from PDF (CFF, PostScript, etc) and convert it to TTF (not simply wrap as CFF but convert outlines). Visual glyph editing can also be easily implemented using SVG. Please check http://delphihtmlcomponents.com/FontBrowser.zip compiled demo, it shows all capabilities - read, write, extract, and contains visual glyph editor (simple HtPanel). Only around 100 lines of code. BTW, font class can import glyphs from SVG path. This is part of Office library.
