Question:
How can I tie ImageMagick to CCS?
I want to process an uploaded image
i.e.
convert -size 120x90 input.jpg -thumbnail 120x90 output_thumbnail.gif
mogrify -format gif -size 120x90 -thumbnail 120x90 *.jpg
as in http://www.cit.gu.edu.au/~anthony/graphics/imagick6/thumbnails/
So far I have found the following topics but they don't cover this
http://forums.codecharge.com/posts.php?post_id=51639
http://forums.codecharge.com/posts.php?post_id=46787
Questions:
1. Shall I use "After Process File"?
2. How do I run 'mogrify' or 'convert' command from CSS?
Shall I use the following syntax?
system("convert ....");
Thanks in advance,
Viktor

Hello Victor:
You can do it like this.
In Before Inset from your Form with the FileUpload:
if ($YourForm->YourUploadField->Value <> "")
{
$max_width = 100;
$tempfile = "/tmp/" .$YourForm->YourUploadField->GetValue();
$new_file = "pictures/" .$YourForm->YourUploadField->GetValue();
createImage($max_width,$tempfile,$new_file);
}
An in your Common you must insert the Image Function:
$ImageTool = "im"; // Work with "im" or "gd"
function CreateImage($size,$source,$dest) {
$sourcedate = 0;
$destdate = 0;
global $convert;
if (file_exists($dest)) {
clearstatcache();
$sourceinfo = stat($source);
$destinfo = stat($dest);
$sourcedate = $sourceinfo[10];
$destdate = $destinfo[10];
}
if (!file_exists("$dest") or ($sourcedate > $destdate)) {
global $ImageTool;
$imgsize = GetImageSize($source);
$width = $imgsize[0];
$height = $imgsize[1];
$new_width = $size;
$new_height = ceil($size * $height / $width);
if ($ImageTool == "gd") {
$im = ImageCreateFromJPEG($source); // GD 2.0...
$new_im = ImageCreate($new_width,$new_height);
ImageCopyResized($new_im,$im,0,0,0,0,$new_width,$new_height,ImageSX($im),ImageSY($im));
ImageJPEG($new_im,$dest,75);
} elseif ($ImageTool == "im") {
system("/usr/bin/convert -scale $new_width" . "x" . "$new_height \"$source\" \"$dest\" 2>&1");
}
}
}
You must rename the Form and Fieldname to your Names!
good luck
martin

Thanks Martin
BUT
You have mentioned about
$ImageTool = "im"; // Work with "im" or "gd"
What about ImageMagick?
Thanks!

Hello.
$ImageTool = "im"; // Work with "im" or "gd"
im = ImageMagick
gd = GD

Hello again
I've tried - no luck.
So I've tried the way from simple-to-complex
(1) This command works from UNIX ok
===========
/usr/local/bin/convert /usr/home/<home>/public_html/files/para_images/200505161407210.Wine_Glass.jpg -resize 64x64 200505161407210.Wine_Glass.jpg
(2) I've tried it using online coding
In 'After Process File" added:
global $paragraph;
system("/usr/local/bin/convert /usr/home/<home>/public_html/files/para_images/\"$para_image\" -resize 64x64 \"$para_image\" ");
as well as
system("/usr/local/bin/convert /usr/home/<home>/public_html/files/para_images/$para_image -resize 64x64 $para_image ");
But no luck
Please advise,
Thanks in advance!

Hello.
On Linux System the convert Directory is not allways the same.
It is hear:
'/usr/X11R6/bin/'
or hear
'/usr/local/bin/convert/'
or hear
'/usr/bin/'
Some Syntax for Image Magick .
/usr/bin/convert
-geometry
"150x150 "
-font Verdana -pointsize 15 -fill BLACK -border 1 -bordercolor BLACK -quality 100 -draw 'text 10,100 "STEMPELTEXT"
'
"/usr/local/httpd/htdocs/shop/images/MEINEQUELLE.GIF"
"/usr/local/httpd/htdocs/shop/images/STEMPEL.GIF"
In php:
$convert_path='/usr/bin/convert';
$convert_size_x=150;
$convert_size_y=150;
$convert_font='Verdana';
$convert_pointzize=15;
$convert_fontcolor='BLACK';
$convert_bordersize=1;
$convert_bordercolor='BLACK';
$convert_quality=100;
$convert_start_x=10;
$convert_start_y=100;
$convert_text='MEIN STEMPELTEXT';
$convert_source='/usr/local/httpd/htdocs/shop/images/MEINEQUELLE.GIF';
$convert_target='/usr/local/httpd/htdocs/shop/images/STEMPEL.GIF';
system($convert_path.' -geometry "'.$convert_size_x.'x'.$convert_size_y.' " -font '.$convert_font.' -pointsize '.$convert_pointzize.' -fill '.$convert_fontcolor.' -border '.$convert_bordersize.' -bordercolor '.$convert_bordercolor.' -quality '.$convert_quality.' -draw 'text '.$convert_start_x.','.$convert_start_y.' "'.$convert_text.'"' "'.$convert_source.'" "'.$convert_target.'"');
1. First only the Convert Directory:
2. Aktion: Like resize, scale, geometry..
3. Resize Or Scale height X wide.
4. More Actions.
5. Orginal File.
6. New File.
