Richard Wolfgram commented on PDFBOX-2843:
------------------------------------------
Nevermind - I figured it out - I just took a look at PDFTextStreamEngine and
added the following operators in the constructor:
addOperator(new BeginText());
addOperator(new Concatenate());
addOperator(new DrawObject()); // special text version
addOperator(new EndText());
addOperator(new SetGraphicsStateParameters());
addOperator(new Save());
addOperator(new Restore());
addOperator(new NextLine());
addOperator(new SetCharSpacing());
addOperator(new MoveText());
addOperator(new MoveTextSetLeading());
addOperator(new SetFontAndSize());
addOperator(new ShowText());
addOperator(new ShowTextAdjusted());
addOperator(new SetTextLeading());
addOperator(new SetMatrix());
addOperator(new SetTextRenderingMode());
addOperator(new SetTextRise());
addOperator(new SetWordSpacing());
addOperator(new SetTextHorizontalScaling());
addOperator(new ShowTextLine());
addOperator(new ShowTextLineAndSpace());
I think I will be able to figure out exactly what I need to include to do what
I want to do. I am processing the text of each page, converting rotated text
and playing with space widths then comparing results against multiple language
dictionaries to improve text stripping.

> Project: PDFBox
> Issue Type: Bug

> Affects Versions: 2.0.0
> Environment: JDK 8 on Windows 7
> Reporter: Richard Wolfgram
> Attachments: Hello World.pdf, StripperTest18.java, StripperTest20.java
>
>
> When using the following override method of PDFTextStripper I am getting a
> large difference in values for TextPosition.getWidthOfSpace() between version
> 1.8.6 and pdfbox-2.0.0-20150611.100833-1423
> {code}
> @Override
> protected void processTextPosition(TextPosition textPos)
> {
> float spaceWidth = textPos.getWidthOfSpace();
> float width = textPos.getWidth();
> System.out.println(textPos.getCharacter() + " - Width of Space=" +
> spaceWidth + " - width=" + width);
> builder.append(textPos.getCharacter());
> }
> {code}
> In 1.8.6 average character width is around 5 and space width is around 2.5
> In 2.0 average character width is around 5 and space width is around 27
