    Custom text rendering

    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.

    Custom text rendering

    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

    Little teaser

    Screencast
  9. This is my fault, code for image should be <img style="position:fixed;top:-100%; left:0px;" src="_INCLUDED_VIA_LINK_Briefbogen_Demo_Full.png" width="210mm" height="297mm"/> <img style="position:fixed;top:-100%; left:0px;" src="_INCLUDED_VIA_LINK_Briefbogen_Demo_Full.png" width="210mm" height="297mm"/> because 100vh is calculated from inner page size. Using this code image covers page exactly. flexbox is supported in 4.4, but for paged media tables have better support (spliting across pages).
  10. As I wrote previously, this can be solved by image in page header (position: running(heading)). Please use the following HTML: <!DOCTYPE html> <html> <style> .page {page-break-before: always} @page {size: A4 portrait; margin: 0px} </style> <body> ...document content... <div style="position: running(heading);height:70px"> <img style="position:fixed;top:-100%; left:0px;" src="_INCLUDED_VIA_LINK_Briefbogen_Demo_Full.png" width="100vw" height="100vh"/> </div> </body> </html> Result:
  11. Header and footer should be defined manually, library supports CSS position: running(heading/footer) Page background can be defined by image in header with fixed position and 100% width/height. To split document to pages add CSS page-break-before/after: always to any element. Finally call THtDocument.HTMLtoPDF

    Parsing Text search expression

    It can. Just override GetDialect method (uses sqlparse) type TCustomExpression = class(TSQLExpression) private FDialect: TSQLDialect; public function GetDialect: TSQLDialect; override; destructor Destroy; override; end; destructor TCustomExpression.Destroy; begin FDialect.Free; inherited; end; function TCustomExpression.GetDialect: TSQLDialect; begin if FDialect = nil then FDialect := TSQLDialect.Create; Result := FDialect; end; procedure TForm67.Button1Click(Sender: TObject); var SE: TCustomExpression; begin SE := TCustomExpression.Create(nil); SE.ParseString('user=''john'' or user = ''peter'''); ShowMessage(SE.Node.Children[0].Children[1].Name); //=john end; Also there is pascal expression class in htscriptparse unit: var SE: TScriptExpression; begin SE := TScriptExpression.CreateAndParse('(user=''john'') or (user = ''peter'')'); SE.Variables['user'] := 'peter'; ShowMessage(SE.Calc)

    Synedit Help

    Usually schema changing occurs rarely enough (much less frequently that typing in query editor) so reloading changed part right after change should not affect performance.

    Synedit Help

    >>This is exactly what I would like to do. Very nice! Are you parsing the whole SQL text with each keypress? Yes, but it works very fast. >>In my project the database schema is "loaded on demand" in a background thread. Queries/Scripts/Batchmove runs in that background thread. And I store the metadata also in that thread. That's why I need to get call the completion form when receiving the message. But taking into account that schema is loaded only once, is there reason to fill autocomplete asynchronously? You can start background loading when necessary and fill autocomplete only if schema is already loaded.

    Synedit Help

    Maybe to use preloaded database schema? In this case completion can be filled synchronously with no significant delay.
