This CFC looks very promising, but the rhe link to download imageCFC isn't working: http://www.opensourcecf.com/download.cfm?p=1

In IE it's giving the old Page cannot be displayed. In firefox, it's redirecting me to http://cfopen.org/frs/?group_id=87, which then cannot be displayed.

worked fine for me. Maybe cfopen was down when you tried.

I'm an amateur needing some help. Need some documentation reading an image's dimensions using ImageCFC. Can someone tell me where there's any other examples besides the examples on this site?

Thanks.

OK... how do we pass the getImageInfo objImage argument in. Could you give us an example of that?

you would typically only do that if you had the imageCFC return on image object rather than write out a file. It would return the image object and then you could pass it back to the image CFC for further manipulation - essentially allowing you to do multiple modifications (resize, crop, whatever) before saving it back out to disk.

Works great if I comment out the "required attribute". I was thinking of adding a function and passing it back if you think others would be interested. I was thinking about having something that created a maximum size by passing in maximun height and width. Then scale proportionally to which size was most intrusive. (It could be used to return either the dimentions or in turn used to size and store an actuall image.) What do you think?

And in your example... do you have to copy a font to the directory to make that work as written on your example code page?

it works great anyway, just pass in an empty string as the image object if you're not using it.

As for the font, it can be located anywhere on the system as long as you specify the full path... ie:



or something like that.

The code below is giving me the following error:

Element IMG is undefined in STRIMAGE.

Can anyone please tell me what I am doing wrong?



You did not select an image, please #CGI.HTTP_REFERER#">go back to select an image.






















Scaled to
640 width and text added:

#cffile.serverfile#" />

Width: #strImageInfo.width# pixels

Height: #strImageInfo.height# pixels

I didn't notice the no HTML allowed! message below, let me know where I can send the code so you can view it and tell me what I am doing wrong.

Awesome CFC by the way, in the process of switching from custom image tag to this CFC.

Thanks,

I realized what the mistake was when trying multiple operations on the same image and loading the image obj rather than defining an input file. The issue I am facing is that when using the scaleX function first and passing the img object to the addtext function, the image is not written to file. I also noticed that this issue is documented on the following site by the author of the blog: http://www.remotesynthesis.com/blog/index.cfm/2006/4/3/Image-Manipulation-with-OpenSource-Imagecfc

When using the individual functions and specifying an input file, the functions work fine. I am interested in the ability of scaling down the image and adding text as you did in your example. If you can offer assistance or post something here that will help resolve the issue, we would greatly appreciate it. I am trying to update previous apps that I worked on from custom tags to your cfc which seems to produce better quality results.

Thanks in advance!

I was able to resolve the issue I was having, you can follow up on it at the following link: http://www.easycfm.com/forums/viewmessages.cfm?Forum=12&Topic=9698

I built on an example from the following blog: http://www.remotesynthesis.com/blog/index.cfm/2006/4/3/Image-Manipulation-with-OpenSource-Imagecfc

The example I provided has a form and a form handler that can be modified to work in any application, all you have to do is customize it to suit your needs.

Hope the information that I posted is helpful for those who are having trouble!
