I found the problem and fixed this locally. I'm busy cleaning up the
fix, then test against all available PDF viewers I have. This fix should
be in the repo in a day or two.

I was maybe unclear in my request. The unit tests are implemented with
the FPCUnit API - and always will be (even though both FPCUnit and
FPTest have compatibility interfaces with each other). I'm simply asking
for the two program files to be added - for convenience. Similar to what
the *.lpi files are added to FCL, even though Free Pascal doesn't
include Lazarus IDE.

Ah, I see it now. Thanks. At the time of my message I was still
kick-starting my brain with my first cup of coffee. ;-)


ps:
  What is FPC's policy on using unittest frameworks? Does it only allow
  FPCUnit based test projects in FCL. The unittest units for fcl-pdf
  are already FPCUnit and FPTest compatible. All that is missing is the
  Console and GUI project files for FPTest support (located in the Wisa
  repository). Adding those two files, if possible, would be greatly
  appreciated.

Hah !

You think you've tested everything, and then this kind of thing pops up :-)

I committed a quick fix which should fix the comma issue, but it still needs to

This is an extract of some stream on your file:


/F3 23 Tf

BT
70,87 785,31 TD
(Basic Shapes) Tj
ET
1 0 0 RG
0,21 0,7 0,27 rg
1 J
3 w
85,04 615,23 113,39 56,69 re

An this is how it should look:


/F3 23 Tf
0 0 0 RG
BT
70.87 785.31 TD
(Basic Shapes) Tj
ET
1 0 0 RG
0.21 0.7 0.27 rg
1 J
3 w
85.04 615.23 113.39 56.69 re

so your locale is playing a role here, numeric conversions in the pdf  
library should be made locale agnostic.

try to change your decimalseparator to "." before and try again.

Michael.


The problem of evince not showing some texts it's because the compressed font 
file stream size is written with an incorrect value. There is an option to 
enable font file compression (poCompressFonts) but in the code, compression 
is always enabled, the compressed stream size is returned in the function 
that writes down the compressed stream, too late because the /length item was 
already written using the uncompressed size. The attached patch addresses 
both problems and makes sure length1 item is not written down if not needed.


I will wait till Graeme comes back and discuss this with him: 
The solution with 'Hidden' property does look very much like a hack :/




This however doesn't fix the Cyrillic and other texts :(


Well:

in each case thank you very much for identifying the problem, 
this is a great help !

I did some fixes for 3.0 prior to committing, and the test suites ran fine

Yes. Do you downloaded it from

If so, even using this file above I get same problem (Windows 7 64

I don't have the code with me so can't check now. But if the issue is 
with Times related text, then FreeFont-ttf.zip should have nothing to do 
with the issue you are experiencing. From memory, the FreeFont font is 
used for the Unicode text only.


I'll take a look on my return in a week's time (if Michael doesn't beat 
me to it). I'll retest with the latest Adobe Reader - clearly it is more 
strict than older Adobe Reader versions.


If anybody knows of a online PDF validator (not a PDF Achive format 
validator), that would help a huge amount.

FYI,

Opening up this document with the latest Adobe Reader DC 
(15.10.20059.40980, on Windows 8.1/64), I get an error message saying


"The font 'Times' contains a bad /BBox"...

Hm. Strange.





Can you send me the PDF you got ?



It's a pleasure :-)

Seems empty here too.

This is what I get with the normal test font:
http://www.freepascal.org/~michael/test.pdf

Can you please try with the original font too, please ?
(freesans is freely available)

If that works, it would mean there is something wrong with the Arial font 
handling.

Attached patch to fix warns/hints. (need to test it with FPC 2.6, I tested
only in 3.0)

Yes. I'm trying to get that, it seems more related to the TComponent class,
that uses interfaces.
