get encoded image without ^XA and ^XZ

[icyz]

How can I get only ZPL code without ^XA and ^XZ ?
Actually I can trim out those tags, but there is any elegant solution? I've inspected the code but didn't see anything for that.

Thanks

One way to do this is with a workaround:

$decoder = GdDecoder::fromPath($imagePath);
$image   = new Image($decoder);

$bytesPerRow = $image->width();
$byteCount   = $bytesPerRow * $image->height();

$zplImage = "^GFA,$byteCount,$byteCount,$bytesPerRow,{$image->toAscii()}";
