Tiff Image Display Modification

[Garibaldi]

I'd like to announce the availability of the Tiff Image Display Modification. This modification for Coppermine 1.4.x allows users to upload tiff images and have them be displayed just like jpgs or pngs. The way it works is it detects if the user is uploading a tiff and then converts it to a jpg, while keeping a copy of the original tiff for the user to download as well. The jpg version is then displayed in the gallery, and the original tiff is available for download via a link in the Custom User Field 2.

Requirements:
This modification requires that you use Imagemagick to handle your images as it is needed to convert the tiffs to jpgs

*NEW* - the uploaded tiffs are now deleted when you delete a picture. To add this feature and upgrade from 1.0.x, please see this post.

See the attachments for some screenshots.

A support topic for this modification is available on the Support Board.
If you are having trouble, you can enable debug on this mod by finding:

Code Select Expand

$g_debug = false;
and replacing it with:

Code Select Expand

$g_debug = true;
This will show debug output on each phase of the upload process

A bugfix from Tom can be found in this post below.

#
   Log in as an administrator and go to Config. Expand the section
   "Custom fields for image description (leave blank if unused)" and
   enter a name in "Field 2 name" like "Download Tiff". Now, expand the
   section "Files and thumbnails advanced settings" and for
   "Method for resizing images", select "Image Magick". Fill in the
   "Path to ImageMagick 'convert' utility", e.g. "/usr/bin/" . Save the new
   configuration.

Upload the tiff_downloads/ folder into the albums/ folderand chmod it
to 777. It must have group read/write permissions for the tiff images
to be uploaded

    // start garibaldi
    $g_query = "SELECT user2 FROM {$CONFIG['TABLE_PICTURES']} WHERE pid='$pid'";
    $g_result = cpg_db_query($g_query);
    $g_user2 = mysql_fetch_array($g_result);
    foreach($g_user2 as $key => $value) {
if (strpos($value, "http") === false) {
} else {
// if its the url, grab it and cut off the part we don't want and put on the server path
$path = str_replace($CONFIG['ecards_more_pic_target'], "", $value);
}
    }
    if (is_file($path)) {
    unlink($path);
    }
    // end garibaldi

Hi.  I recently downloaded and installed Coppermine, and I really do think it's an amazing tool.  One of my primary image types for what I'm doing is multi-page TIF, and I noticed one omission in the UPLOAD.PHP modifications that I think would be helpful to fix.

The ImageMagick parameters are not being pulled into the CONVERT statement in the current code.  The following is what I did to resolve this:


Original:            exec("convert " . $path_to_image . " " . $path_to_jpg, $convert_output_arr);       // do the conversion to create a jpg
Updated:           exec("convert " . $CONFIG['im_options'] ." " . $path_to_image . " " . $path_to_jpg, $convert_output_arr);       // do the conversion to create a jpg

Also, I added the following switch to the imagemagick options in the config:

-delete 1--1

That command will basically force the convert utility to only pick up the first page as the thumbnail for these multi-page TIF files.

Hope this helps anyone else out that is using TIF's.  I'm planning on applying the TIF conversions to the BATCH upload as well over the next couple weeks (I'm no expert in PHP, so it's going to take me a while!).

Hi Tom,

Thanks for fixing this! I'll add a link to your post to the first post in this thread and will include your modification in the next release

[Kodak_SLRc]

Hi Garibaldi,

I've updated to 1.5.6, then went to make your mod, but it looks like your mod needs to be updated too. Will you be finding time to do this?

Thanks,
Tom F.

[Garibaldi]

Hi Tom,

I will try and take a look at it soon - though I am unfamiliar with Coppermine 1.5 so I'm not sure about the changes that would be required. What issues have you run into when installing the mod on your 1.5 site?

[Kodak_SLRc]

Since I really don't know php, I stopped editing the 1.5 files as soon as I could not find the lines of code that one needs to find to install the mod. Two examples I recall, 1) they did away with the URI thing and 2) they changed some array names. (I learned code in the days of BASIC, FORTRAN, and Pascal, so I really don't know the naming conventions/scope rules/etc in any of the modern languages. Thanks to your precise editing instructions I can make the mods with confidence but without exact matches then I'm afraid I'll muck it up.)

My gallery, including the TIFFs uploaded prior to the 1.5 upgrade, is working fine. However I will not be able to upload any TIFFs until this mod is updated.

Sorry I can't be more helpful and thank you very much for sharing your code.

Tom F.

[phill104]

Yo don't need a mod. Simply go into config>FileSettings and add to "Allowed Document Types" tif/tiff

Do not add it to "Allowed image types" as some users seem to be doing.

It will not be displayed in the same way as above and I have only tested with GD2 but I am sure Imagemagik will support it.

[Kodak_SLRc]

Hi Phill,

I seem to recall that I tried your suggestion in the past but it didn't offer the functionality that the Garibaldi mod did. To whit, to display a conveniently-sized jpeg while allowing download of large (10+ MB) TIFFs.

In an attempt to refresh my memory, I tried your suggestion. I got this error when I tried to upload a TIFF (it had a .tif extension):
"Error
Only files with the following extensions are accepted: jpg/jpeg/gif/png/asf/asx/mpg/mpeg/wmv/swf/avi/mov/mp3/midi/mid/wma/wav/ogg/tiff/doc/txt/rtf/pdf/xls/pps/ppt/zip/gz/mdb"

I don't understand why tif is not in the list... attached is a screenshot of part of the config.

Thanks,
Tom

[phill104]

That is indeed very strange as those settings should allow it. Try saving those settings again.

Also please try installing this plugin and see if tiff is included in the list - http://forum.coppermine-gallery.net/index.php/topic,59917.0.html

As for functionality, no, it will not give the same. All you will get is a thumbnail and a full size image. This mod has not yet been implemented on 1.5.x

[Kodak_SLRc]

Something odd in my installation - the filetypes editor plugin was installed but did not show up at the bottom of the config page. I enabled the plugin manager and found the filetypes editor version was 1.0.2 (I think), leftover from the CPG 1.4.x installation (I think) and not updated when I upgraded to 1.5.x. So I deleted the old and uploaded the new (v2.1) and installed it using the plugins manager. Frustratingly, it still didn't show up at the bottom of the config page. Nonetheless I accessed it directly from the plugins manager using the button located there.

The attached shows what I found: tif was set as image. IIRC, it needed to be that way for the Garibaldi mod to work. I changed tif to document and voila, the tif upload works as you suggested.

But at the end of the day, this is really not what I need. The Garibaldi mod is exactly what I need and I hope his life allows for him to update it some day.

Thanks,
Tom
