image quality problem

I only set either height or either with. Not both. This way I get constant witdh, but images takes on original height. No quality loss.
Hope this helps!

Hi,
when you decrease image size its quality decreases too.

There is nothing you can do with this.
I recommend you using thumbnailsto have both decreased and original images at the site.

Hi Stephan,
Thx for your response. I fixed only the width, it didn't work, still the same poor quality.

Hi Alexey,
I think image resizing will work in this case, image resizing takes care of image resizing without having quality loss.
I have the following image resizing code:
_
if(!$bad_file_flag)

{
// define new width, and height will be calculated by itself

$new_width = 450;
// filename will just be the current UNIX timestamp...

$fname = time() . $i;
//

move_uploaded_file($_FILES[$element_name][tmp_name],$vehicle_image_dir

.. "/$fname$file_extension");

// chmod($vehicle_image_dir . "/$fname$file_extension", 0666);

$tmp_image =imagecreatefromjpeg($_FILES[$element_name]['tmp_name']);

$width = imagesx($tmp_image);

$height = imagesy($tmp_image);
$new_height = round(($height / 100) (100 / $width $new_width),

0);
$new_image = imagecreatetruecolor($new_width, $new_height);

ImageCopyResized($new_image, $tmp_image,0,0,0,0, $new_width,

$new_height, $width, $height);

ImageJPEG($new_image,$vehicle_image_dir ."/$fname$file_extension");

ImageDestroy($tmp_image);

ImageDestroy($new_image);
// move_uploaded_file($image_buffer, $vehicle_image_dir

.."/resized$fname$file_extension");

chmod($vehicle_image_dir . "/$fname$file_extension", 0666);
mysql_query("INSERT INTO dah_images (filename,

vehicle_id)VALUES('$fname$file_extension', $insert_id)");

}

else

{

// remove the bad file - we don't know what this is!

@unlink($_FILES[$element_name][tmpname]);

};

Could you pls help me with implementing this code into the PHPRunner code ?
Thanks !

Bul,

I think image resizing will work in this case, image resizing takes care of image resizing without having quality loss.

I'm afraid you are wrong.
I still recommend you using Thumbnailsfeature.

It performs resizing the same way as your code does.

Hi Alexey,
Thank you for your reply.
Suppose I have already a few hundred images in an existing database.

How can I display images on the listing & view page without sacrificing the quality of the original images

(and without re-uploading all the images again) ?
Thx.
Best regards,
Bul

Bul,
looks like we are talking about different things.
Please give me an example of a resized image with and without quality loss.

Give me URL or send screenshots to support@xlinesoft.com

Hi Alexey,
Thank you very much for your response.
(original photo 2)
(original photo 1 resized to 390 x 293, there is no quality loss)

Bul,
I see what you saying.
In the first example browser resized the images and did it very crudely.

The second image is resized by specialized image-processing software like Adobe Photoshop and it looks much better.

Furthermore they look better than the original image does.
Use a specialized software to resize images if their quality is significant for you.

PHP resize code wouldn't make them look as good as your example does.

Hi Alexey,
Thank you very much for your kind response !
The quality that the PHP resize code provides is sufficient.

You are the expert, could you please help me with implementing the PHP resize code into the PHPRunner code (assuming an existing database) ?
Thanking you very very much !

Hi Alexey,

Hello Alexey,
Would you please help me ???
Many many thanks.
Regards.
Bul

Bul,
there is no need in additional code here.

To resize newly uploaded images use thumbnails.

To resize existing images use some specialized software i.e. ACDSee.
