Word�s bounds

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi!

Please tell me how to define bounds(in pixels) of exact word.

For example.

I could get the bounds of exact line using function GetPageText(4):

"PDMFNG+CMR10", {Font}

#000000, {Color}

10.90, {Font Size}

72.0009,628.7132,512.1819,628.7132,512.1819,639.6223,72.0009,639.6223, {Bounds}

"Although there is a long history of empirical research into the deformation behaviour of" {Text line}

 But how can I define the bounds of word 'history' for example?

	Hi Dmitry, As far as I know: If GetPageText cannot split the text to single words then you can't. Maybe you can make the pdf available so that someone can debug it in source to see, why it can't splitt into single words and if there is a solution. best regards, Uli

	The PDF Specification allows for a virtually unlimited number of ways in which text can be laid out in a document all the way from one character at time to a paragraph wrapped down an entire page. This means that is nearly impossible to know for certain where a word is or that it even is a word using text extraction methods. The easiest solution to your problem lies in controlling how the document is created. If you have no control over that you are probably out of luck.

	BTW, I just develope the next algorithm ASentence := Text; //Sentence AWord := ErrorWord; // The word that needs to be underlined WPos := Pos(AWord, ASentence); BefWord := Copy(ASentence, 1, WPos-1); AfWord := Copy(ASentence, 1, WPos+Length(AWord)); BM:= TBitmap.Create; // Creating bitmap BM.Canvas.Font.Name:=FontName; BM.Canvas.Font.Size:=FontSize; WordBeginPos:=(BM.Canvas.TextWidth(BefWord)); WordEndPos:=(BM.Canvas.TextWidth(AfWord)); Afword:=IntToStr(WordEndPos); LTop := LineBounds.LeftTop.Y; LLeft := LineBounds.LeftTop.X+4; Qp.SetLineColor(1,0,0); // red Qp.DrawLine(LLeft+WordBeginPos,LTop,LLeft+WordEndPos,LTop); But this method defines the wrong begin and end positions of the AWord.

	Hi Dimitry! I don't know much enough about pdf ;-) My thoughts are: You have the beginning point (pixel) of the string and you have the ending point (pixel) of the string... and you can get the length of the string... i think with a bit maths it should be possible to get the position of a special word you're searching for...?
