Right, but we have access to _the actual glyph bounds_ and we're not using it.

To wrap this one up, revisiting my questions above:

{quote}
1) what is the correct thing to do?
2) what should we do for 2.0?
{quote}

The answers would seem to be:
1) visual bounds but only if its not really slow (and we don't know, because we 
haven't tried)
2) keep the 1.8 heuristic to be pragmatic

Timo Boehme commented on PDFBOX-3062:

I would like to second the proposal of Tilman to use the currently best working 
solution (as verified by his tests) using BBox and CapHeight in the rare cases 
where BBox has unusual large values. Since PDF was not designed for text 
extraction it is normal to use some heuristics to cope with the shortcomings 
produced by different PDF creators.

It might be good to later change to using the own calculated glyph bounds but 
this has to be tested and optimized for performance as well as how this 
influences the text extraction quality (algorithms might have to be adjusted as 
well). So I don't see this can/should be done in the 2.0 RC cycle but will be a 
target for 2.1.

{quote}
How is it not reliable?
{quote}

Why would it be? There's no reason it should be more accurate than the bbox - 
neither are used during rendering.

{quote}
That's why CapHeight is used when the BBox isn't helpful.
{quote}

The CapHeight also isn't a good proxy for a glyph's visual bounds. Many glyphs 
will be higher or lower than that.

{quote}
calculate a new BBox from actual glyphs: will make software slower
{quote}

Sounds like FUD to me.

Re reliability, see the test files and the files in this issue and related 
issues. Their extraction improve thanks to the last change.

{quote}
The CapHeight also isn't a good proxy for a glyph's visual bounds. Many glyphs 
will be higher or lower than that.
{quote}
I doubt that glyphs will be higher. And I'm only using it if it is smaller than 
BBox height / 2.

"will make software slower" is not FUD, it is logical: there are extra 
calculations to make. We need to get the paths, which we don't need currently, 
and we'll need to calculate the bounds.

BBox + CapHeight isn't reliable either. 
{quote}
How is it not reliable? Do you know of any files that get less tokens extracted?

{quote}
The BBox is fine, it's just not what you want it to be, i.e. a meaningful proxy 
for a glyph's visual bounds. {quote}
That's why CapHeight is used when the BBox isn't helpful.

{quote}
So are we going to solve that problem or not?{quote}
Don't know. The alternatives are:
- use BBox only: some files won't be extracted nicely
- use BBox + Capheight: more files will be extracted nicely, but the code will 
have 9 extra lines you don't like
- calculate a new BBox from actual glyphs: will make software slower, will 
delay release, may or may not be more reliable. (If a font subset has only 
non-capital glyphs, then the 1/2 of the "real bbox" would be too small)

BBox + CapHeight isn't reliable either. Either we should be using a reliable 
metric, or using some logical metric, but combining two metrics doesn't make 
sense.

Then the next JIRA issue will be "Text extraction and height different in 2.1". 
We can stick with bbox for 2.0 but we shouldn't be trying to be backwards 
compatible with 1.8's broken hybrid metrics. So I'd suggest bbox for 2.0, new 
stuff for 2.1, no hybrid stuff anywhere.

[jira] [Commented] (PDFBOX-3062) Text extraction and height different in 2.0

2015-12-01 Thread Tilman Hausherr (JIRA)

Tilman Hausherr commented on PDFBOX-3062:
-

This isn't really about metrics, this is about text extraction. The text 
extraction fails for some files if one uses the bbox only. It just isn't 
reliable enough. Users won't be happy if some files that did extract properly 
in the past no longer extract.

People who just want the sizes can still decide whether they want to use the 
values from PDFBox, or calculate their own.

Can't we use the current approach for 2.0 and work on a better one (glyphs's 
bounds) for 2.1.

Tilman Hausherr commented on PDFBOX-3062:
-

I ran a test on about 2500 files. The change results in more splitting, i.e. 
more stuff will be on different lines. This applies mostly for subscript and 
superscript (where it happens often before the change too), but it will result 
in better text extraction re: looking for tokens. And it will allow me to 
resolve this issue.

One existing test file is modified: PDFBOX-3038-001033-p2.pdf. The "1" and "2" 
are now on different lines than the text after the number. Two other 
superscript numbers are on the same line - there is no universal solution for 
this.

I am also adding some new test files to the repository, and adding the ones 
that are possibly copyrighted to my own test set. If anyone is interested, I 
can temporarly upload my complete test set to my website.

In case this change goes too far, one could try to set a different rule than 
{{capHeight < glyphHeight}}, e.g. {{capHeight < glyphHeight * 0.75}}.

If we use the visual bounds to get the actual bbox we'll be slower.

The problem with the bbox is that it isn't always correct.

John Hewson commented on PDFBOX-3062:
-

Technically, the bbox is always correct - it's the bbox, by definition. If 
that's what's in the PDF, then that's the bbox. It's not supposed to be the 
visual bounds of the glyph, nor is it supposed to be the smallest box that all 
glyphs fit within, it's simply a box large enough for all glyphs to fit in. So 
the problem is not with the bbox, it's that we're trying to treat it as 
something that it's not.

Trying to emulate the visual bounds via a combination of bbox and cap height is 
madness when we have access to the glyph's exact bounds already. Either we're 
using the bbox for something, or we're using the glyph's bounds, but anything 
else is not going to end well.

So, the real question is philosophical: are we going to use the bbox or the 
glyph's bounds? We didn't have access to the bounds in the past, so this was 
never a question. We need to choose to either do this or not though - no more 
hacks.

Tilman Hausherr commented on PDFBOX-3062:

I tried using CapHeight when available, but the results were very bad. Using 
CapHeight as a fallback worked nicely on my test set, there were only 
acceptable differences.
{code}
float glyphHeight = bbox.getHeight() / 2;

// sometimes the bbox has very high values, but CapHeight is OK
PDFontDescriptor fontDescriptor = font.getFontDescriptor();
if (fontDescriptor != null)
{
float capHeight = fontDescriptor.getCapHeight();
if (capHeight != 0 && capHeight < glyphHeight)
{
glyphHeight = capHeight;
}
}
{code}
I'll test this change with a larger test set. (but not today)

PDFBOX-3062-H6NIYQXHLPGD3GI6SNIYINRAZBCDHUCB.pdf uses the Cambria font. I found 
the same problem in another file using that one (001065.pdf). However this is 
not with every file, in some others the extreme Y values have been corrected.

At the same time, I've noticed yesterday that many files I had marked for 
further review are now good.

They are already good anyway, probably due to the recent change that the 
fontBBox is taken from the dictionary and not from the font. I have not done a 
change to use CapHeigth. This is done in 1.8 only.

Tilman Hausherr commented on PDFBOX-3062:

But the BBox height is huge... the result is that text that is on different 
lines is extracted as being on the same line.

Yes we could of course get a real BBox by getting through the glyphs like I 
recently did for type 3 fonts. But that would make text extraction slower.

At this time I'm not saying that anything should be done. This might just be a 
single file that won't extract nicely. (Although the extraction will still be 
OK for a search engine)

At the same time, I've noticed yesterday that many files I had marked for 
further review are now good.

Those BBox values are pretty reasonable though, certainly not implausible. 
Neither CapHeight nor XHeight make sense as substitutes for BBox - we know 
those values will always be smaller.

With my previous comment in mind, I've deprecated PDFont#getHeight(). It wasn't 
used anyway.

PDFBOX-3062-N2MOQ7YZICIYGTPLQJAWJ4HLN6CCEMHZ-reduced.pdf has the same problem, 
but with the opposite effect - due to a bad height stuff that is on separate 
lines is put together. (Which results in an incredible mess when using the sort 
option)

John Hewson commented on PDFBOX-3062:
-

Height isn't calculated in a meaningful way in either 1.8 nor 2.0. 
Font#getHeight() shouldn't exist, as there's no such thing as the logical 
height of a glyph. Height in PDFTextStripper is calculated incorrectly by 
PDFTextStreamEngine#showGlyph(), note that this is deliberate as legacy 
PDFTextStripper behaviour depends on it. If you want to fix this, then start by 
deleting all of that showGlyph override except for the final part which does 
the additional Unicode mapping (as we want to keep that). Then fix 
PDFTextStripper.

I suspect that the calculations in TextPosition are also incorrect. It's 
important to realise that we should dealing with _logical_ width, as returned 
by PDFont#getWidth() (which is in glyph space, so make sure to convert that to 
user space) and _logical_ height, which is simply the current font size (with 
the TM + CTM taken into account). Note that the textRenderingMatrix (TRM) 
passed to onGlyph already has all of these calculations done for you... so use 
that!

Enjoy!
