The jpeg2wbmp() function is an inbuilt function in PHP which is used to convert JPEG image file to WBMP image file.

Syntax:

bool jpeg2wbmp( string $jpegname, 
int $wbmpname, int $dest_height, 
int $dest_width, int $threshold )

Parameters: This function accepts five parameters as mentioned above and described below:

  • $jpegname: It specifies the path to JPEG file.
  • $wbmpname: It specifies the path to destination WBMP file.
  • $dest_height: It specifies the destination image height.
  • $dest_width: It specifies the destination image width.
  • $threshold: It specifies the threshold value.

Return Value: This function returns TRUE on success or FALSE on failure.

Below given programs illustrate the jpeg2wbmp() function in PHP:
Program 1:




<?php
// Path to the JPEG image which
// is to be converted
$path = './geeksforgeeks.jpg';
  
// Get the image sizes which includes
// the height and width
$image = getimagesize($path);
$height = $image[1];
$width = $image[0];
  
// Convert image the image and save as test.wbmp
jpeg2wbmp($path, './converted.wbmp', $height, $width, 5);
echo 'JPEG converted into WBMP successfully.';
?> 






                        










Output:


This will save the WBMP version of JPEG in the same folder.


Program 2:













                                    




                                    

                                    




                                    




                                    

                                    

                                    
                                




















<?php 


// Path to the JPEG image which 


// is to be converted 


$path = './geeksforgeeks.jpg'; 


  


// Get the image sizes which includes 


// the height and width 


$image = getimagesize($path); 


$height = $image[1]; 


$width = $image[0]; 


  


// Convert image the image and save as test.wbmp 


jpeg2wbmp($path, './converted.wbmp', $height, $width, 1); 


  


$im = imagecreatefromwbmp('./converted.wbmp'); 


  


header('Content-type: image/png'); 


imagepng($im); 


?>
