It is specifically designed -// for geometric calculations within R3 (affine vector space) -// and R4 (homogeneous vector space). -// -// Note: The terms 'affine' or 'affine coordinates' are not really correct here -// because an 'affine transformation' describes generally a transformation which leads -// to a uniquely solvable system of equations and has nothing to do with the dimensionality -// of a vector. One could use 'projective coordinates' but this is also not really correct -// and since I haven't found a better name (or even any correct one), 'affine' is as good -// as any other one. -// -// Identifiers containing no dimensionality (like affine or homogeneous) -// and no datatype (integer..extended) are supposed as R4 representation -// with 'single' floating point type (examples are TVector, TMatrix, -// and TQuaternion). The default data type is 'single' ('GLFloat' for OpenGL) -// and used in all routines (except conversions and trigonometric functions). -// -// Routines with an open array as argument can either take Func([1,2,3,4,..]) or Func(Vect). -// The latter is prefered, since no extra stack operations is required. -// Note: Be careful while passing open array elements! If you pass more elements -// than there's room in the result the behaviour will be unpredictable. -// -// If not otherwise stated, all angles are given in radians -// (instead of degrees). Use RadToDeg or DegToRad to convert between them. -// -// Geometry.pas was assembled from different sources (like GraphicGems) -// and relevant books or based on self written code, respectivly. -// -// Note: Some aspects need to be considered when using Delphi and pure -// assembler code. Delphi ensures that the direction flag is always -// cleared while entering a function and expects it cleared on return. -// This is in particular important in routines with (CPU) string commands (MOVSD etc.) -// The registers EDI, ESI and EBX (as well as the stack management -// registers EBP and ESP) must not be changed!

All parts of this code which are not finished or not conforming exactly to - the XmlSpec are marked with three exclamation marks - --!- Parts where the parser may be able to detect errors in the document's syntax are - marked with the dash-exlamation mark-dash sequence. -=============================================================================================== -Terminology: ------------- -- Start: Start of a buffer part -- Final: End (last character) of a buffer part -- DTD: Document Type Definition -- DTDc: Document Type Declaration -- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No. -- Cur*: Fields concerning the "Current" part passed back by the "Scan" method -=============================================================================================== -Scanning the XML document -------------------------- -- Create TXmlParser Instance MyXml := TXmlParser.Create; -- Load XML Document MyXml.LoadFromFile (Filename); -- Start Scanning MyXml.StartScan; -- Scan Loop WHILE MyXml.Scan DO -- Test for Part Type CASE MyXml.CurPartType OF -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; - END; -- Destroy MyXml.Free; -=============================================================================================== -Loading the XML document ------------------------- -You can load the XML document from a file with the "LoadFromFile" method. -It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your -application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever -protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method. -"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated -string, thereby creating a copy of that buffer. -"SetBuffer" just takes the pointer to another buffer, which means that the given -buffer pointer must be valid while the document is accessed via TXmlParser. -=============================================================================================== -Encodings: ----------- -This XML parser kind of "understands" the following encodings: -- UTF-8 -- ISO-8859-1 -- Windows-1252 - -Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry. - -Every string which has to be passed to the application passes the virtual method -"TranslateEncoding" which translates the string from the current encoding (stored in -"CurEncoding") into the encoding the application wishes to receive. -The "TranslateEncoding" method that is built into TXmlParser assumes that the application -wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able -to convert UTF-8 and ISO-8859-1 encodings. -For other source and target encodings, you will have to override "TranslateEncoding". -=============================================================================================== -Buffer Handling ---------------- -- The document must be loaded completely into a piece of RAM -- All character positions are referenced by PChar pointers -- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0) - or reference the buffer of another instance or object (then, FBuffersize is 0 and - FBuffer is not NIL) -- The Property DocBuffer passes back a pointer to the first byte of the document. If there - is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character. -=============================================================================================== -Whitespace Handling -------------------- -The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content: -While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all -Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are -compressed to one. -If the "Scan" method reports a ptContent part, the application can get the original text -with all whitespace characters by extracting the characters from "CurStart" to "CurFinal". -If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or -use CurStart/CurFinal. -Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters -as the XmlSpec requires (XmlSpec 2.11). -The xml:space attribute is not handled by TXmlParser. This is on behalf of the application. -=============================================================================================== -Non-XML-Conforming ------------------- -TXmlParser does not conform 100 % exactly to the XmlSpec: -- UTF-16 is not supported (XmlSpec 2.2) - (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser) -- As the parser only works with single byte strings, all Unicode characters > 255 - can currently not be handled correctly. -- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11) - (Workaround: The Application can access the text contents on its own [CurStart, CurFinal], - thereby applying every normalization it wishes to) -- The attribute value normalization does not work exactly as defined in the - Second Edition of the XML 1.0 specification. -- See also the code parts marked with three consecutive exclamation marks. These are - parts which are not finished in the current code release. - -This list may be incomplete, so it may grow if I get to know any other points. -As work on the parser proceeds, this list may also shrink. -=============================================================================================== -Things Todo ------------ -- Introduce a new event/callback which is called when there is an unresolvable - entity or character reference -- Support Unicode -- Use Streams instead of reading the whole XML into memory -=============================================================================================== -Change History, Version numbers -------------------------------- -The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order. -Versions are counted from 1.0.0 beginning with the version from 2000-03-16. -Unreleased versions don't get a version number. - -Date Author Version Changes ------------------------------------------------------------------------------------------------ -2000-03-16 HeySt 1.0.0 Start -2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site -2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent -2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway) -2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements; - Should be backwards compatible. - AnalyzeDtdc: Set CurPartType to ptDtdc -2000-04-23 HeySt 1.0.5 New class TObjectList.

Thanks to Rene Hugentobler for pointing out this bug, - - Revision 1.3 2004/02/18 22:35:51 savage - Brought sdl.pas up to 1.2.7 compatability - Thus... - Added SDL_GL_STEREO, - SDL_GL_MULTISAMPLEBUFFERS, - SDL_GL_MULTISAMPLESAMPLES - - Add DLL/Shared object functions - function SDL_LoadObject( const sofile : PChar ) : Pointer; - - function SDL_LoadFunction( handle : Pointer; const name : PChar ) : Pointer; - - procedure SDL_UnloadObject( handle : Pointer ); - - Added function to create RWops from const memory: SDL_RWFromConstMem() - function SDL_RWFromConstMem(const mem: Pointer; size: Integer) : PSDL_RWops; - - Ported SDL_cpuinfo.h so Now you can test for Specific CPU types. - - Revision 1.2 2004/02/17 21:37:12 savage - Tidying up of units - - Revision 1.1 2004/02/05 00:08:20 savage - Module 1.0 release - -} -{******************************************************************************} - -{$I jedi-sdl.inc} - -interface - -uses -{$IFDEF __GPC__} - system, - {$IFDEF WINDOWS} - wintypes, - {$ELSE} - {$ENDIF} - gpc;

Do not close TSQLiteDatabase before any TSQLiteUniTable, - because query is closed on TSQLiteUniTable destructor and database connection - is used during TSQLiteUniTable live! - - SQL parameter usage: - You can add named parameter values by call set of AddParam* methods. - Parameters will be used for first next SQL statement only. - Parameter name must be prefixed by ':', '$' or '@' and same prefix must be - used in SQL statement! - Sample: - table.AddParamText(':str', 'some value'); - s := table.GetTableString('SELECT value FROM sometable WHERE id=:str'); - - Notes from Andrew Retmanski on prepared queries - The changes are as follows: - - SQLiteTable3.pas - - Added new boolean property Synchronised (this controls the SYNCHRONOUS pragma as I found that turning this OFF increased the write performance in my application) - - Added new type TSQLiteQuery (this is just a simple record wrapper around the SQL string and a TSQLiteStmt pointer) - - Added PrepareSQL method to prepare SQL query - returns TSQLiteQuery - - Added ReleaseSQL method to release previously prepared query - - Added overloaded BindSQL methods for Integer and String types - these set new values for the prepared query parameters - - Added overloaded ExecSQL method to execute a prepared TSQLiteQuery - - Usage of the new methods should be self explanatory but the process is in essence: - - 1. Call PrepareSQL to return TSQLiteQuery 2. Call BindSQL for each parameter in the prepared query 3. Call ExecSQL to run the prepared query 4. Repeat steps 2 & 3 as required 5. Call ReleaseSQL to free SQLite resources - - One other point - the Synchronised property throws an error if used inside a transaction. - - Acknowledments - Adapted by Tim Anderson (tim@itwriting.com) - Originally created by Pablo Pissanetzky (pablo@myhtpc.net) - Modified and enhanced by Lukas Gebauer - Modified and enhanced by Tobias Gunkel -} - -interface - -{$IFDEF FPC} - {$MODE Delphi}{$H+} -{$ENDIF} - -uses - {$IFDEF MSWINDOWS} - Windows, - {$ENDIF} - SQLite3, Classes, SysUtils;

In this - * case, the following will happen: - * - * 1. FreeType looks for a bitmap for the glyph corresponding to the - * face's current size. If one is found, the function returns. The - * bitmap data can be accessed from the glyph slot (see note below). - * - * 2. If no embedded bitmap is searched or found, FreeType looks for a - * scalable outline. If one is found, it is loaded from the font - * file, scaled to device pixels, then "hinted" to the pixel grid in - * order to optimize it. The outline data can be accessed from the - * glyph slot (see note below). - * - * Note that by default, the glyph loader doesn't render outlines into - * bitmaps. The following flags are used to modify this default - * behaviour to more specific and useful cases. - * - * FT_LOAD_NO_SCALE :: - * Don't scale the vector outline being loaded to 26.6 fractional - * pixels, but kept in font units. Note that this also disables - * hinting and the loading of embedded bitmaps. You should only use it - * when you want to retrieve the original glyph outlines in font units. - * - * FT_LOAD_NO_HINTING :: - * Don't hint glyph outlines after their scaling to device pixels. - * This generally generates "blurrier" glyphs in anti-aliased modes. - * - * This flag is ignored if @FT_LOAD_NO_SCALE is set. - * - * FT_LOAD_RENDER :: - * Render the glyph outline immediately into a bitmap before the glyph - * loader returns. By default, the glyph is rendered for the - * @FT_RENDER_MODE_NORMAL mode, which corresponds to 8-bit anti-aliased - * bitmaps using 256 opacity levels. You can use either - * @FT_LOAD_TARGET_MONO or @FT_LOAD_MONOCHROME to render 1-bit - * monochrome bitmaps. - * - * This flag is ignored if @FT_LOAD_NO_SCALE is set. - * - * FT_LOAD_NO_BITMAP :: - * Don't look for bitmaps when loading the glyph. Only scalable - * outlines will be loaded when available, and scaled, hinted, or - * rendered depending on other bit flags. - * - * This does not prevent you from rendering outlines to bitmaps - * with @FT_LOAD_RENDER, however. - * - * FT_LOAD_VERTICAL_LAYOUT :: - * Prepare the glyph image for vertical text layout. This basically - * means that `face.glyph.advance' will correspond to the vertical - * advance height (instead of the default horizontal advance width), - * and that the glyph image will be translated to match the vertical - * bearings positions. - * - * FT_LOAD_FORCE_AUTOHINT :: - * Force the use of the FreeType auto-hinter when a glyph outline is - * loaded. You shouldn't need this in a typical application, since it - * is mostly used to experiment with its algorithm. - * - * FT_LOAD_CROP_BITMAP :: - * Indicates that the glyph loader should try to crop the bitmap (i.e., - * remove all space around its black bits) when loading it. This is - * only useful when loading embedded bitmaps in certain fonts, since - * bitmaps rendered with @FT_LOAD_RENDER are always cropped by default. - * - * FT_LOAD_PEDANTIC :: - * Indicates that the glyph loader should perform pedantic - * verifications during glyph loading, rejecting invalid fonts. This - * is mostly used to detect broken glyphs in fonts. By default, - * FreeType tries to handle broken fonts also. - * - * FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH :: - * Indicates that the glyph loader should ignore the global advance - * width defined in the font. As far as we know, this is only used by - * the X-TrueType font server, in order to deal correctly with the - * incorrect metrics contained in DynaLab's TrueType CJK fonts. - * - * FT_LOAD_NO_RECURSE :: - * This flag is only used internally. It merely indicates that the - * glyph loader should not load composite glyphs recursively. Instead, - * it should set the `num_subglyph' and `subglyphs' values of the glyph - * slot accordingly, and set "glyph->format" to - * @FT_GLYPH_FORMAT_COMPOSITE. - * - * The description of sub-glyphs is not available to client - * applications for now. - * - * FT_LOAD_IGNORE_TRANSFORM :: - * Indicates that the glyph loader should not try to transform the - * loaded glyph image. This doesn't prevent scaling, hinting, or - * rendering. - * - * FT_LOAD_MONOCHROME :: - * This flag is used with @FT_LOAD_RENDER to indicate that you want - * to render a 1-bit monochrome glyph bitmap from a vectorial outline. - * - * Note that this has no effect on the hinting algorithm used by the - * glyph loader. You should better use @FT_LOAD_TARGET_MONO if you - * want to render monochrome-optimized glyph images instead. - * - * FT_LOAD_LINEAR_DESIGN :: - * Return the linearly scaled metrics expressed in original font units - * instead of the default 16.16 pixel values. - * - * FT_LOAD_NO_AUTOHINT :: - * Indicates that the auto-hinter should never be used to hint glyph - * outlines. This doesn't prevent native format-specific hinters from - * being used. This can be important for certain fonts where unhinted - * output is better than auto-hinted one. - * - * FT_LOAD_TARGET_NORMAL :: - * Use hinting for @FT_RENDER_MODE_NORMAL. - * - * FT_LOAD_TARGET_LIGHT :: - * Use hinting for @FT_RENDER_MODE_LIGHT. - * - * FT_LOAD_TARGET_MONO :: - * Use hinting for @FT_RENDER_MODE_MONO. - * - * FT_LOAD_TARGET_LCD :: - * Use hinting for @FT_RENDER_MODE_LCD. - * - * FT_LOAD_TARGET_LCD_V :: - * Use hinting for @FT_RENDER_MODE_LCD_V. - *) -const - FT_LOAD_DEFAULT = $0000; - FT_LOAD_NO_SCALE = $0001; - FT_LOAD_NO_HINTING = $0002; - FT_LOAD_RENDER = $0004; - FT_LOAD_NO_BITMAP = $0008; - FT_LOAD_VERTICAL_LAYOUT = $0010; - FT_LOAD_FORCE_AUTOHINT = $0020; - FT_LOAD_CROP_BITMAP = $0040; - FT_LOAD_PEDANTIC = $0080; - FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH = $0200; - FT_LOAD_NO_RECURSE = $0400; - FT_LOAD_IGNORE_TRANSFORM = $0800; - FT_LOAD_MONOCHROME = $1000; - FT_LOAD_LINEAR_DESIGN = $2000; - - (* temporary hack! *) - FT_LOAD_SBITS_ONLY = $4000; - FT_LOAD_NO_AUTOHINT = $8000; - - (*************************************************************************) - (* *) - (* <Enum> *) - (* FT_Render_Mode *) - (* *) - (* <Description> *) - (* An enumeration type that lists the render modes supported by *) - (* FreeType 2.
