Re: [Ming-dev] Problem : Maximum file size 64K only?

[Catherine L. <cat...@ya...>]

Dear All,
   Hmmm.... I had a thorough test with different senarios in my php, found that if I have swf files with many lines, polygons into shapes without any SWFText elem, it can go beyond than 64K   However, once I have SWFText elem in php, I can only see the SWF file being display [$movie->output()] if the file size is <=64K, Meanwhile, I get a BLANK page if it goes beyond >64K [$movie->save("xxx.swf")].
   Something is very weird, just now, I accidentally hit with this algorithm, and I got to see the file being display (included SWFTEXT elem with 80k file size), under condition if I save the file at least TWICE and then Display through IE:
    ...
$movie->save('c:\inetpub\wwwroot\webemap\swfoutput\Sample1.swf');
$movie->save('c:\inetpub\wwwroot\webemap\swfoutput\Sample1.swf');
 header('Content-type: application/x-shockwave-flash');
 $movie->output();

it won't work if I have it save to a file once, nor directly display thru IE, it must save to a file at least TWICE.... weird eh?
 
   Is it possible the PROBLEM cause by following algo :
<?php 
$movie = new SWFMovie();
$movie->setRate(12.000000);
$movie->setDimension(2880,1720);
$movie->setFrames(1);
$movie->setBackground(219,227,173);
$Sprite = new SWFSprite();
$s = new SWFShape();
$s->setLine( 14,251, 252, 253);
$s->movePenTo(-1154.3, -615.26);
$s->drawLineTo(-1064.33, -636.53);
$s->drawLineTo(-868.78, -660.37);
$s->drawLineTo(-658.92, -686.61);
$s->drawLineTo(-570.69, -708.07);
$s->drawLineTo(-267.83, -889.31);
$i = $Sprite->add($s);
$s = new SWFShape();
... /*repeat adding shape with lines into same sprite *?
$Sprite->nextFrame();
$clip = $movie->add($Sprite);
$clip->moveTo(1440,860);
$clip->setName('Road');
....
...
$f= new SWFFont("Arial.fdb");
$Sprite = new SWFSprite();
/*Repeat with this block with many text at different location and rotation into Sprite name TEXT*/$t = new SWFText();
$t->setFont($f);
$t->setHeight(20);
$t->setColor(0,0,0);
$i = $Sprite->add($t);
$str_text = "St. xxx";
$t->addString("$str_text");
$i->move(-737.32, 389.42);
$i->rotate(0);
 $Sprite->nextFrame();
$clip = $movie->add($Sprite);
$clip->moveTo(1440,860);
$clip->setName('TEXT');
      ....
$movie->nextFrame();  /* (end of frame 0) */
$movie->save('c:\inetpub\wwwroot\webemap\swfoutput\Sample1.swf');
$movie->save('c:\inetpub\wwwroot\webemap\swfoutput\Sample1.swf');
 header('Content-type: application/x-shockwave-flash');
 $movie->output();

   Finally, I don't think it cause by the ActionScript, as I didn't include any on my PHP, just play with Shapes, lines...and Text only.  
 
   Any Idea? Many Thanks.
 
Regards,
Catherine

Hi Catherine,

I am generating swf files much bigger than that (e.g. containing mp3 sounds)
What is is that exactly stops at a 64 k boundary - can you explain your way of generating
map more in detail?
The swf format itself restricts the size of some elements to 64 k, such as an individual
actionscript statement
