[Ming-dev] CVS - Text not working

[Armel G. <ml...@ar...>]

hi list

I've tried to compile from CVS (with php_ext)

Many things seem to work, but text_fields disappear and I've got some crashes with text

Any idea about what causes that ?

[Ming-dev] UTF8 - Problems with Characters > 127

[Steve A. <al...@ne...>]

Hi,

The last extension for multibyte support in ming makes many problems.

Especially UTF8GetChar() in utf8.c can't be work.

All european chars, eg. german umlauts, france chars and also the
european currency symbol for Euro results broken strings after passed
UTF8GetChar. All characters between ascii 127 (eg. Euro symbol 128)
and 224 returns 0xffff.

I think it is not possible to make an 'auto-detection' of wide and
normal
charsets.


The seconds problem is SWFFontCharacter_getGlyphCode() is sometimes
calling with a negative c value. The result is a segfault. I think
this is also a problem with the new wide font code.


Regards,


Steve

[Ming-dev] [PATCH] C++ consts and a couple new movie methods

[Bradley D. L. <br...@lt...>]

I don't know what the procedure for getting stuff into CVS is,
so I send this patch to the list.  Please tell me if there is
a preferred way.  Thank you.

Regards,
Brad

[Ming-dev] mx compression implemented

[Steve A. <al...@ne...>]

Hi developer,


I've just implement the Macromedia Flash MX compression in the current
cvs tree.

I hope it works correctly, but please _test_ this new feature!

I have only made a part implementation with the normal api (add
SWFMovie_outputC)
and with php-4.2.0 and php-4.3.dev extensions.
Perl, Pyton, Ruby and Java are not affected!

It's currently only implement in php $movie->save() and in
$movie->output().

To test the new feature try the follow way:

use:
$movie->output(int compression_level[0..9]);
$movie->save(string filename, int compression_level[0..9]);

The compression level is optionally and if no present, the old format is
writting.
The compression level must be between 0 (no compression) and 9 (max
compression, but slow). Macromedia use 5 or 6 as default.

The version number is automatic changed to 6 instead of 5.

Temporary i've add a copy of SWFMovie_output() called
SWFMovie_outputC().

If all test succeed, i'll remove the old SWFMovie_output() function and
replace it with SWFMovie_outputC().

zlib.h is now required for the swf compression feature.


Any comments are welcome.

Regards,

Steve

[Ming-dev] wide font code working

[Dave H. <da...@op...>]

I just checked in some fixes to the font stuff to make 16-bit fonts work.
You can use UTF8 strings with the existing function calls, or use the new

  SWFText_addWideString(SWFText text, const unsigned short* str, int len);

function to add a wide string.  (Maybe the input string should be
0-terminated instead of using a length arg?)

I haven't tried running this from PHP, but I don't know why it wouldn't
work.  But then, I never do when it doesn't..

[Ming-dev] PHP Integration

[Steve A. <al...@ne...>]

Hi list,

i've seen that Dave has back porting ming.c from PHP 4.2.2.

It is principal a good idea, but Dave has overwritten my change in this
file, and I have also back porting ming.c from 4.3.0dev.

Both version (4.2.2 and 4.3.0dev) are completely different, because in
4.3.0dev are using php streams instead of the normal file handling.

Eg.

PHP_FUNCTION(swfmovie_saveToFile)
{
        zval **x;
        SWFMovie movie = getMovie(getThis() TSRMLS_CC);
        php_stream *what;

        if (ZEND_NUM_ARGS() != 1 || zend_get_parameters_ex(1, &x) ==
FAILURE) {
                WRONG_PARAM_COUNT;
        }
        ZEND_FETCH_RESOURCE(what, php_stream *, x,
-1,"File-Handle",php_file_le_stream());
        RETURN_LONG(SWFMovie_output(movie, &phpStreamOutputMethod,
what));
}

instead of the old handling
PHP_FUNCTION(swfmovie_saveToFile)
{
  zval **x;
  SWFMovie movie = getMovie(getThis() TSRMLS_CC);
  void *what;

  if((ZEND_NUM_ARGS() != 1) || zend_get_parameters_ex(1, &x) == FAILURE)
    WRONG_PARAM_COUNT;

  ZEND_FETCH_RESOURCE(what, FILE *, x,
-1,"File-Handle",php_file_le_fopen());
  RETURN_LONG(SWFMovie_output(movie, &phpFileOutputMethod, what));
}

We should more coordinate the back porting from php tree.

I can commit every changes in php_ext/* the php cvs tree, because I have
PHP CVS access. I think we should stop the back porting and make all the
changes in the ming tree.

Maybe we could split the cvs tree in 4.2.x and 4.3.x versions.

Any suggestions?

[Ming-dev] more buggy fun

[Dave H. <da...@op...>]

I just checked in a mess of stuff to the Ming CVS, though not at much as
it would seem when you see nearly every file update..

Cosmetic changes: tabified code, added emacs tab-width define thingies, 
added spaces and linebreaks according to random whim, changed 2001 to 2002
(only seven months later!).

SWFFont is now two things, SWFFont and SWFFontCharacter.  SWFFont is
read-only after you load it, so you can use the same font object across
many movies (handy if your fdb file is 5 megs..), while SWFFontCharacter
holds all of the state information.  Oh, and I've added code for 16-bit
fonts, but haven't tested it yet.  Since it didn't work before I figured
it was okay to add broken code. ;)

SWFMovie and SWFMovieClip had to change their weird dependency inheritance
code to deal with the above changes but I think I fixed some problems
along the way where characters were used before they were defined.

I also added Goto's sound code, though I haven't tested that either.  That
adds support for "event" type sounds, raw pcm, adpcm, or mp3 format.  The
old SWFSound object has been moved to SWFSoundStream to accommodate, and
there's an SWFSoundInstance object which will someday be used to tweak the
sound event data- loop points, envelopes, and whatever else SWF allows
for.
