[SOLVED] PHP Image Conversion Help..

[PhaZZed]

Hi all,

 

I have spent the last age trying to create a simple image conversion class, and have just not been able to get anywhere. I am limited to using the PHP GD Library unfortunately, so image magick is not an option.

 

I have managed to convert from:

 

.jpg to .gif and .png

 

But I need to convert from:

 

.jpg to .bmp and .tiff

 

I tried this code:

 

      $image = @imagecreatefromjpeg($filename);
      if ($image === false) { die ('Unable to open image'); }
      $height = imagesy($image);
      $width = imagesx($image);
      $bmpdest = "../bmp/" . $rand . ".bmp";
      $bmp = jpeg2wbmp($filename, $bmpdest, 100, 100, 4);

 

But the .bmp is shown as invalid when I try open with an application.

 

If anyone has any information or, well, absolutely anything that can help, it would be greatly appreciated if you would share your knowledge.

 

Thanks!

.bmp is a special Windows format.  You can't "convert" to a .bmp.  The GD package includes a wbmp format but that's a special wireless image format not bmp

I realized that it's for WAP basically.

 

So, there isn't a way to convert to bmp then I take it

Try it with http://phpthumb.sourceforge.net/.

won't do TIFF and it does say BMP but its using the GD library so i think thats only WBMP

Madtechie, ye Wbmp is the conversion, which is mono graphic for WAP purposes, argh this is so annoying!

 

Phpthumb.. someone else mentioned that, but I have not looked into it yet, seems like a way over kill for something like this..

[MadTechie]

what about

jpeg2wbmp

 

if you are after WBMP.. if not then i think i found one awhile ago (will search my computer)

See http://phpthumb.sourceforge.net/index.php?source=phpthumb.bmp.php.

WBMP is not what I am after.

 

@gurroa - Ok, this is a little over my head, how would I pass a .jpg file to a function of that class? Sorry to be an annoyance, I'm just swimming in the deep end at the moment!

 

Thanks!

include('phpthumb.functions.php');
include('phpthumb.bmp.php');

$jpg = imagecreatefromjpeg('test.jpg');
$phpbmp = new phpthumb_bmp();

file_put_contents('test.bmp', $phpbmp->GD2BMPstring($jpg));

[PhaZZed]

@gurroa - that's really kind of you! Seems to be working just fine, finally some progress! Now to try and tackle the jpg to tiff conversion, which I feel is going to be even worse!

[MadTechie]

 

maybe

http://www.imagemagick.org/script/index.php

[PhaZZed]

include('phpthumb.functions.php');
include('phpthumb.bmp.php');

$jpg = imagecreatefromjpeg('test.jpg');
$phpbmp = new phpthumb_bmp();

file_put_contents('test.bmp', $phpbmp->GD2BMPstring($jpg));

 

Absolutely perfect, managed to edit a couple things so I could still pass another header() function, so things are working now! .tiff formatting, and then I can finally move onto a new module of this project, what a good feeling!

 

thanks thanks thanks
