PHP - Imagemagick Help

Hi all

I have created the below script to resize my images and it works fine for landscape images but if you select a portrait image it saves it as a landscape image. How do I modify the script so it keeps the same aspect ratio?

Code: [Select]
copy($_FILES['image1']['tmp_name'], WEB_UPLOAD."images/adverts/test/".$_FILES['image1']['name']) or die("Error uploading image.");
$ext = strtolower(substr($_FILES['image1']['name'], strrpos($_FILES['image1']['name'], ".")));
$rand = rand(1, 100000000000000);
$name = $rand . $ext;
$image_small = $rand . $ext;
rename(WEB_UPLOAD."images/adverts/test/".$_FILES['image1']['name'], WEB_UPLOAD."images/adverts/test/".$name) or die("Error renaming image.");;
$go = WEB_UPLOAD.'images/adverts/test/'.$name;
$stop = WEB_UPLOAD.'images/adverts/test/'.$image_small;
exec ("/usr/bin/convert $go -resize 10%\> -quality 100 $stop");
unset($scale, $go, $stop);

Many thanks for your help.

Hi,

Very new to PHP and am enjoying learning the ins and outs etc, but while creating my mam a website, ive ran into a problem while uploading, resizing and saving the file to my web host. Initially i used imagecreatefromjpeg, but this was taking too much memory up, so opted to use imagemagick. All of the features work apart from the file getting saved to the uploads directory on my web space. They always get saved to the root. If someone could help i would be very grateful. The code ive got currently is:

<?php

// If the form has been submitted do this
if(isset($_POST['submit'])) { 

// Temporary upload image name
$original_image = $_FILES['photo']['tmp_name']; 

// Get the image dimensions
$size=GetImageSize( $original_image );

// Name to save the image as - in this case the same as the original
$new_image = $_FILES['photo']['name'];

// Maximum image width
$max_width = "600";

// Maximum image height
$max_height = "300";

// Resize the image and save
exec("convert -size {$size[0]}x{$size[1]} $original_image -thumbnail $max_widthx$max_height $new_image");

echo "File uploaded<br>";

echo "<img src=\"".$new_image."\">";
}

?>

Hopefully someone could help

Many thanks,

Matk.

Hi

I'm trying to resize pictures for thumbnails

I can do this correctly at linux command line with the following command

convert ideologies.jpeg -resize 300x200 ./Thumbnails/testphp.jpg

However trying to wrap this in PHP doesn't seem to work

// Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){
            // Insert image file name into database
            $insert = $conn->query("INSERT into Threads (Title, ThreadBody, filename) VALUES ('$Title', '$BodyText', '$fileName')");
            if($insert){
                $statusMsg = "The file ".$fileName. " has been uploaded successfully.";
exec("convert {['fileName']} -resize 300x200 wankertestphp.jpg");
            }

If you look above I do successfully hit the "The File has been uploaded successfully" line so it is entering that If statement.

I've also checked the Threads table with a Select * from Threads and I can see the $fileName variable is entering there.  I've tried numerous different ways around the $fileName variable (removing the brackets...removing the brackets and the apostrophes")

 

Any help is appreciated.

(1) What does this actually do? (compress it?)

$image = imagecreatefromjpeg("image.jpg");
header('Content-Type: image/jpeg');
imagejpeg($image);

By using this rather than displaying by using www.site.com/image.jpg it reduces file size of an image from 2.5mb to 0.5mb !!

(2) ImageMagick can't get these results. Am I doing something wrong? If I change the pixel size of an image in ImageMagick then I can reduce its file size, but (1) above reduces file size regardless of changing pixel size.

hello dear php-experts and freaks

how to view photos and to rapidly change the major categories

i have several hundred images (photographs) taht i want to view on opensuse linux version 13.1


i want to view the images - and of while doing so i want to turn the colored images into b/w

Question; which is the best - ie. the quickest way to do so.

note; i have installed the following thigns on my opensuse 13.1:

- gimp the great grahical tool
- digicam - the great tool to view images and pictures
- Gwenview Version 4.11.4 on KDE 4.11.5


so again here the question: which tool allowes to view the color(ed) image and to turn it - on the fly - in to black and white?

BTW: can i tell linux to swith the colors - in general - to black and white? is this doable...

looks like we could write a small shell script, utilizing imagemagick.

maybe like this:
Code:

for i in *jpg ; do mogrify -colorspace Gray "$i" ; done

this is just a quick hack. i have tried. See more bleow: Also, it's not interactive and simply changes all jpg's to grayscale, even if they already are grayscale.

please note that we need to have some more things about imagemagick.
  well see the results:

martin@linux-70ce:~/Bilder>
martin@linux-70ce:~/Bilder> for i in *jpg ; do mogrify -colorspace Gray "$i" ; done
mogrify: unable to open image `*jpg': Datei oder Verzeichnis nicht gefunden @ error/blob.c/OpenBlob/2643.
mogrify: no decode delegate for this image format `*jpg' @ error/constitute.c/ReadImage/552.
