Hi,

In my gallery a have to put one watermark on TOP and one on botton right, but when i try, only the last watermark stay on image.

//FAZ O PROCESSO DE MARCA D'AGUA
$ImgMod = new Upload($ImagemCompleta);
$ImgMod->file_auto_rename = false;
$ImgMod->file_overwrite = true;
	
//APLICA A MARCA 1 NO TOPO	
if ( file_exists($Marca1) == true ) {
  $ImgMod->image_watermark = $Marca1;
  $ImgMod->image_watermark_position = 'T';
}	

//APLICA A MARCA 2 NO CANTO INFERIOR DIREITO
if ( file_exists($Marca2) == true ) {
  $ImgMod->image_watermark = $Marca2;
  $ImgMod->image_watermark_position = 'BR';
}	

$ImgMod->process( $PastaTemp );

It is normal. The $ImgMod->image_watermark is not a method, it is a property. So the second time you set it, you remove the first value that you put there.

In order to add two watermarks, you need to call Process() twice.

For instance, something like this:
$ImgMod = new Upload($ImagemCompleta);
$ImgMod->file_auto_rename = false;
$ImgMod->file_overwrite = true;
	
if ( file_exists($Marca1) == true ) {
  $ImgMod->image_watermark = $Marca1;
  $ImgMod->image_watermark_position = 'T';
}	

$ImgMod->process( $PastaTemp );

$ImgMod = new Upload($PastaTemp);
$ImgMod->file_auto_rename = false;
$ImgMod->file_overwrite = true;

if ( file_exists($Marca2) == true ) {
  $ImgMod->image_watermark = $Marca2;
  $ImgMod->image_watermark_position = 'BR';
}	

$ImgMod->process( $PastaTemp );

It no function, because the code take the same image and put other watermark.

I found a solution, fisrt, attach the watermark1, second, take this image and attach the other watermark.

:)
$ImagemTemp     = $PastaTemp.$imagem;

$ImgMod = new Upload($ImagemCompleta);
$ImgMod->file_auto_rename = false;
$ImgMod->file_overwrite = true;
	
if ( file_exists($Marca1) == true ) {
  $ImgMod->image_watermark = $Marca1;
  $ImgMod->image_watermark_position = 'T';
}	
 
$ImgMod->process( $PastaTemp );
 
$ImgMod = new Upload($ImagemTemp);
$ImgMod->file_auto_rename = false;
$ImgMod->file_overwrite = true;
 
if ( file_exists($Marca2) == true ) {
  $ImgMod->image_watermark = $Marca2;
  $ImgMod->image_watermark_position = 'BR';
}	
 
$ImgMod->process( $PastaTemp );

Thx...solved :)Reply
