// Main content: How to use the png2wbmp function in PHP to convert a PNG image to WBMP format</p>
<p>// Introduction to the png2wbmp function:<br>
// The png2wbmp() function is used to convert an image from PNG format to WBMP format.<br>
// Syntax: bool png2wbmp ( string $srcfile , string $destfile [, int $threshold = 128 ] )<br>
// Parameter details:<br>
// - $srcfile: Source PNG file path.<br>
// - $destfile: Destination WBMP file path.<br>
// - $threshold (optional): Black/white threshold, default is 128, which determines which pixels are treated as black.</p>
<p>// Usage example:</p>
<p>$src = 'input.png';     // Input PNG file path<br>
$dest = 'output.wbmp';  // Output WBMP file path</p>
<p data-is-only-node="" data-is-last-node="">if (file_exists($src)) {<br>
$result = png2wbmp($src, $dest);<br>
if ($result) {<br>
echo "PNG successfully converted to WBMP, file saved as: {$dest}";<br>
} else {<br>
echo "Conversion failed, please check the file path or format.";<br>
}<br>
} else {<br>
echo "Source file does not exist, please check the path: {$src}";<br>
}<br>
