Thumbnail Image Quality

[Matthew Prose]

Hello,

I would like to alter the thumbnail image when uploading a new image  
to the library.  I would like to increase the quality of the upload.  
I found this file: farcry/core/packages/farcry/image.cfc and found  
some quality references and changed them to 100 instead of 70, but  
this did nothing.  I even reinitialized the app.  What else could be  
causing the thumbnail to be such low quality?

Matt

Matt,

That is because the built-in image manipulation in FarCry currently  
uses the native java JAI to do image manipulation (the native JAI in  
java doesn't offer the best quality).

Have you considered one of the two available image manipulation  
plugins for FarCry?
1. There's the FarCry CFXImage plugin (requires Windows as the CF  
server)
   http://docs.farcrycms.org/display/FCPLUG/FarCry+CFXImage
2. And there the FarCry CFImage plugin (best quality, but requires CF8  
or better)
   http://docs.farcrycms.org/display/FCPLUG/FarCry+CFImage

Both work in FarCry 4 and FarCry 5.  By using the plugin, all image  
manipulation used by FarCry formtools (basically everything by  
default) will automatically use the new image manipulation plugin to  
override the default JAI image tools.

Regards,

Okay, I have not been able to get a plugin working when I have already installed a project.

How do I know this is installed and working properly?  Where can I adjust the settings for the image uploaded? The documentation says to change the code in:

./farcry/projects/projectName/packages/types/myImagePhotos.cfc 

I do not have a packages folder in my project folder.  Does this have something to do with how I setup farcry on the server?

Matt,

It only affects images you create *after* you've installed the plugin.

Also that example cfc file I gave is just for your custom types.  In this case you don't have any custom types nor have you likely extended the default dmImage object to add custom sizes to the default image library.

If you want to modify existing images, you have two options.  You can either edit each image and recreate the thumbnails from source, or if you have a lot of images you can run a batch script to update them all.  You are welcome to use the batch script I recently released (see this blog post http://bit.ly/1EN24c), but if you're not too familiar with FarCry development just yet you might not want to venture down that road just yet (I'm not currently offering support on that script).  If you want to go down that road I'd strongly advise getting up to speed on FarCry development first (most notably custom types).  The FarCry Developer Jump Start Course is the best place to start for that http://docs.farcrycms.org/display/FCDEV50/Book+of+FarCry

Hello Matt,

generating high quality thumbnails is not as easy as it seems. Take a
look at the following recource:

Thanks

Martin
