Re: [Ming-dev] php extension and rpath

[strk <st...@ke...>]

Oh, now realized that's because the php_ext dir
is still using it's own  own ./configure script
and being used as if it was a completely separate project.

So basically the build tree path of Ming is passed
to configure which then uses rpath over it.

I think this should be fixed, or changes in the build tree 
would affect system behaviour !!

[Ming-dev] php extension and rpath

[strk <st...@ke...>]

I noticed that the php module of Ming gets built
with -rpath pointing to build tree.

This is in the installed version.
Isn't that horribly wrong ?

Try ldd /usr/lib/php5/*/ming.so right after
'make install' ....

Great, test committed :)

BTW, I've noticed that on 'make check' the 'system-wide
installed' module is used rather than the 'just built' one.

I'm pretty sure it used to work some time ago.
Can it be something dependent on perl version ?

test/dotest.pl, which is the script running the testcases
uses this construct:

 $ENV{'PERL5LIB'}=$TOP_BUILDDIR."/perl_ext/blib/arch/auto/SWF/:".$TOP_BUILDDIR."/perl_ext/blib/lib";

Still, unless I 'make install' your patch didn't make effect
on 'make check' (ie: old system-installed libs were used).

Any idea?

[Ming-dev] assignSymbol with perl

[strk <st...@ke...>]

It seems SWFMovie->assignSymbol() is broken
for the perl binding. It insists in taking a Character
but Text doesn't result as being one.

PHP is fine.

Can any perl hacker check ?

The attached testcase can be dropped into test/Movie/assignSymbol
to verify the problem

[Ming-dev] new SWFText(<version>)

[strk <st...@ke...>]

I've noticed there are some discrepancies
wrt how to interpret the argument passed to SWFText
constructor.

For C++ binding it's 2 by default, and creates a DefineText2
in that case, while any other it creates a DefineText.

For perl binding, it's 1 by default, creates a DefineText2
when it's 2, DefineText otherwise.

For php binding, it's 0 by default, creates a DefineText2
when it's 1 (?!), DefineText otherwise.

As for outputscript.c, it seems to always call the Text
constructor with no arg, no matter version.

I think we should standardize this.

A first pass could be to have them all default to 0
and use DefineText2 when it's == 2, and have outputscript.c
follow that semantic.

I'd go that way, but I dunno if the Text version should really
depend on SWF version (thus bound later, at output time).

For now, some consistency seems nice anyway.

Toughts ?

According to the ChangeLog it was known that MVC doesn't like
union-casts. Try explicitly setting members of a SWFMovieBlockType
union instead, and pass the union to SWFMovie_add_internal.

See `cvs diff -r1.74 -r1.75 mingpp.h` for an equivalent case fixed

A little follow-up:
After some further tweaking (like declaring HAVE_NEW_MING as a 
preprocessor directive and compiling as C as opposed to c++ [I don't 
know if that's dangerous or not, but it seems to work]) and searching, 
I've managed to reduce the compiler errors down to the four following ones:

'SWFBlock' to 'SWFMovieBlockType'

1>.\ming.c(5347) : error C2065: 'ret' : undeclared identifier
1>.\ming.c(5348) : error C2065: 'ret' : undeclared identifier

Again, any help/illumination appreciated.
PHP I know well. But C/C++ just gives me a headache.

Re: [Ming-dev] Importing Fonts with PHP Interface

[Ming-dev] Importing Fonts with PHP Interface

[Russ A. <rus...@gm...>]

Hello,

I'm using PHP with libming 0.4.2 to import a font from one swf into another
and use it in the second.  In the process of working on this, I discovered a
potential bug.  Here's the PHP:

$swf_font = new SWFMovie(8);
$swf_font->setDimension(100, 100);
$swf_font->setRate(30);
$f = new SWFFont("arial.ttf");
$fc = $swf_font->addFont($f);
$fc->addChars("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789");
$swf_font->addExport($fc,"arial");
$swf_font->save("arial_font.swf", 0);

$swf_impt = new SWFMovie(8);
$swf_impt->setDimension(11000, 8000);
$swf_impt->setRate(30);
$fc = $swf_impt->importFont("arial_font.swf","arial");
$swf_impt->add($fc);
$txtfield = new SWFTextField(SWFTEXTFIELD_NOEDIT);
$txtfield->setHeight(14);
$txtfield->setColor(0xff, 0x33, 0x33);
$txtfield->setFont($fc);
$txtfield->addString("ABC");
$swf_impt->add($txtfield);
$swf_impt->save("arial_import.swf", 0);

As you can see, in the first block I'm creating the font swf file.  In the
second block I'm importing a font, which returns a SWFFontCharacter.  Later
I try to SWFTextField::setFont() with SWFFontCharacter.  If I'm reading
php_ming.c correctly, I should be able to SWFTextField::setFont() on a
SWFFontCharacter or a SWFFont.  However, I'm getting a segfault on the
setFont method instead.  I dug around a bit, and I think I know why.

In movie.c::SWFMovie_importFont, you see that it returns a dummy
SWFFontCharacter.  In specific the SWFFontCharacter returned does not have
the "font" member specified.  The segfault happens a little later in
blocks/font.c::SWFFont_getFlags().

I found that returning NULL from blocks/font.c::SWFFont_getFlags() at least
prevents the segfault, but this probably not the desired behavior.

Thanks,
Russ

[Ming-dev] Bitmap fill with referencing character 65535

[strk <st...@ke...>]

I'm sure some of you know what I'm talking about:
there are SWF out there containing bitmap fill styles
referencing unexistent (never defined) character id 65535.

When it comes to decompile these movies, it might be
useful being able to also produce such cases.

What would you think about allowing a NULL SWFBitmap argument
here to trigger that behaviour ?

Ok, I took a closer look now and see what you mean.
A couple of questions:

	2. Shouldn't the caller be explicit when it wants

Not really what I was asking.
I'm thinking about an intermediate step, *before* extracting.
This step would be expecting user to perform extraction manually,
using another tool (until one is provided by Ming).

A tool I know for this, currently, is swfextract from SWFTools.
This tool extracts bitmaps into either JPEG files or PNG files
and I dunno based on what. If I know what the policy is, we
can use the same one to guess what would the filename be called
when generating script code (C++,perl,php,python, whatever)
from an SWF.

An attempt to test this (see how swfextract extract bitmaps
based on tag type):

TAG_TYPE          FILENAME                    PNG  JPG
-----------------------------------------------------
DEFINEBITS        2008-election.swf           N    Y

DEFINELOSSLESS2   2008-election.swf           Y    N
DEFINELOSSLESS    215251_escapetheroom.swf    Y    N

Question is: is it general that DEFINEBITS results in a jpg 
or can it be a png too ? (for example).

So we need still some old code.
A testing case inside ming distribution you'll find in

More or less. My primarly goal was to support loading png files
actually, but since I was there I tought it was a good idea
to drop the extension checking as a whole, since the core lib
supports it.

Sure, my code does create an SWFInput from the filename in any case,
so you might as well skip the file opening.

I'm not sure I see a case for handling alpha separaterly.
At least I tought the core lib would read alpha when available
in input (say png).
Jpeg with alpha would be impossible to generate with Ming,
by relying on that.

For clarity, I'm just working on what makes it easier for me
to decompile SWFs to perl scripts for analisys/optimization.
