NAME

       pnmmontage - create a montage of portable anymaps

SYNOPSIS

       pnmmontage [-?|-help] [-header=headerfile] [-quality=n] [-prefix=prefix] [-0|-1|-2|...|-9] pnmfile...

DESCRIPTION

       Packs  images of differing sizes into a minimum-area composite image, optionally producing a C header file with the locations of the subim-
       ages within the composite image.

OPTIONS

       -?, -help
              Displays a (very) short usage message.

       -header
              Tells pnmmontage to write a C header file of the locations of the original images within the packed image.  Each original image gen-
              erates  four  #defines  within  the packed file: xxxX, xxxY, xxxSZX, and xxxSZY, where xxx is the name of the file, converted to all
              uppercase.  The #defines OVERALLX and OVERALLY are also produced, specifying the total size of the montage image.

       -prefix
              Tells pnmmontage to use the specified prefix on all of the #defines it generates.

       -quality
              Before attempting to place the subimages, pnmmontage will calculate a minimum possible area for the  montage;  this  is  either  the
              total  of the areas of all the subimages, or the width of the widest subimage times the height of the tallest subimage, whichever is
              greater.  pnmmontage then initiates a problem-space search to find the best packing; if it finds a solution that is  (at  least)  as
              good  as the minimum area times the quality as a percent, it will break out of the search.  Thus, -q 100 will find the best possible
              solution; however, it may take a very long time to do so.  The default is -q 200.

       -0, -1, ... -9
              These options control the quality at a higher level than -q; -0 is the worst quality (literally  pick  the  first  solution  found),
              while  -9 is the best quality (perform an exhaustive search of problem space for the absolute best packing).  The higher the number,
              the slower the computation.  The default is -5.

NOTES

       Using -9 is excessively slow on all but the smallest image sets.  If the anymaps differ in maxvals, then pnmmontage will pick the  smallest
       maxval which is evenly divisible by each of the maxvals of the original images.

imagejpeg - Output image to browser or file

SYNOPSIS

       bool imagejpeg (resource  $image, [string  $filename], [int  $quality])

DESCRIPTION

       imagejpeg(3) creates a JPEG file from the given $image.

PARAMETERS

	      o $
		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      o $filename
		-The path to save the file to. If not set or NULL, the raw image stream will be outputted directly. To skip this argument in order
		to provide the $quality parameter, use NULL.

	      o $quality
		-$quality is optional, and ranges from 0 (worst quality, smaller file) to 100 (best quality, biggest file).  The  default  is  the
		default IJG quality value (about 75).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Outputting a JPEG image

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Set the content type header - in this case image/jpeg
	      header('Content-Type: image/jpeg');

	      // Output the image
	      imagejpeg($im);

	      // Free up memory
	      imagedestroy($im);
	      ?>

	      The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : Outputting a JPEG image

       Example #2

	      Saving a JPEG image

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Save the image as 'simpletext.jpg'
	      imagejpeg($im, 'simpletext.jpg');

	      // Free up memory
	      imagedestroy($im);
	      ?>

       Example #3

	      Outputting the image at 75% quality

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Set the content type header - in this case image/jpeg
	      header('Content-Type: image/jpeg');

	      // Skip the filename parameter using NULL, then set the quality to 75%
	      imagejpeg($im, NULL, 75);

	      // Free up memory
	      imagedestroy($im);
	      ?>

NOTES

       Note

	      JPEG support is only available if PHP was compiled against GD-1.8 or later.

       Note

	       If you want to output Progressive JPEGs, you need to set interlacing on with imageinterlace(3).
