Access transformation functions via code
Hi,

Can/How would you reference the method GetImage used on transformations (/index.html?newedit_transformation_methods.htm) within code?

RE:Access transformation functions via code
Hello.

What version do you use, please? These methods are available in CMSAbstractTransformation class. So, e.g. in version 4.0, full path to GetImage() method is: CMS.Controls.CMSAbstractTransformation.GetImage()

Hello,

Could you please use following sample code to get URL of file/image (attachmentGuid is guid stored in field of FileUpload type):

this.ResolveUrl(CMS.FileManager.AttachmentManager.GetAttachmentUrl(attachmentGuid, nodeAlias));

Best Regards,
