Generowanie gifów

0

Witam mianowicie mam problem gify po obróbce maja niekiedy białe tło nie wiem dlaczego.Prosiłbym o pomoc z góry dziękuje.
Dodam z góry że nie jestem asem z php ale uczę się :)

Tworzenie gifa.

 $target_path = "uploads/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']); 

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
$img ="uploads/".  basename( $_FILES['uploadedfile']['name']). "";

}
  


require_once("GIFDecoder.class.php");
$FIC=$img;
if(file_exists($FIC))
{
$GIF_frame = fread (fopen ($FIC,'rb'), filesize($FIC));
$decoder = new GIFDecoder($GIF_frame);
$frames = $decoder->GIFGetFrames();
$framesd = $decoder->GIFGetDelays ();
for ( $i = 0; $i < count ( $frames ); $i++ )
{
$fname = ( $i < 10 ) ? "$i.gif" : "$i.gif";
$hfic=fopen ( "output/".$fname, "wb" );
fwrite ($hfic ,$frames[$i] );
fclose($hfic);
}
}



$dir = opendir('output');
while(false !== ($file = readdir($dir)))
{
  if($file != '.' && $file != '..') 
  {
  $image_path='output/'.$file.'';
$text = 'Gifator.pl';

$font = 'Century.ttf';
$font_size = '15';
$angle = 0;
$offset_x = 30;
$offset_y = 30;
$drop_shadow = true;
$shadow_color = '#FFFFFF';
$mode = 1;
$images_folder = 'output/';
$destination_folder = 'rdy/';
include("watermark_text.class.php");
  $filename=$image_path;
  $imgpath = $filename;
  $imgdestpath = $destination_folder . basename($filename);
  $img = new Zubrag_watermark($imgpath);
  $img->setShadow($drop_shadow, $shadow_color);
  $img->setFont($font, $font_size);
  $img->ApplyWatermark($text, $color, $angle, $offset_x, $offset_y);
  $img->SaveAsFile($imgdestpath);
  $img->Free();
}
}

include "GIFEncoder.class.php";

$directory = "rdy/";
if (glob($directory . "*.gif") != false)
{
 $filecount = count(glob($directory . "*.gif"));
$filecount=$filecount-1;
}



for( $x = 0; $x <= $filecount; $x++ )
{

}

        $framed [ ] = $filecount;

co znaczy czasami?
a jakie tło mają mieć oryginalnie? przeźroczyste?
podrzuć kilka gifów którym się zmieniło tło i z jakich plików powstały
specyfikację gifów znam, ale wątpię czy komuś będzie chciało się analizować cały ten kod

0

a pokaż oryginalnego gifa
prawdopodobnie zużywa całą paletę kolorów a dodany przez Ciebie napis rezerwuje jeszcze kolor biały dla tła i podmienia się on z innym
najprościej zrezygnuj z "cienia" przy swoim napisie - zrób go w jednym kolorze
ewentualnie przeszukaj paletę kolorów i stwórz swój napis z najbardziej podobnych kolorów

zbadałem sprawe i biega o te kolory chodzi ze tylko rgb dobrze kowertuje z cmyk ma problemy.Masz może jakaś funkcje bez imagemagick żeby kowertować z cmyk do rgb?
