Re: Back to .NET integration - Enumeration issue
I've now worked around this to some degree by saving the initial image with a .png extension and then re-saving it using cfimage. This seems to work. I'd still like to find out why the other approach with .NET classes didn't work. It's so confusing...

Re: Back to .NET integration - Enumeration issue
I need to warm this thread up again - I am s close... As explained before I was able to use the .NET Bitmap's save method to save an image: The resulting image appears to be a valid JPG image. I say appears because the CFIMAGE tag falls over if I try to read it back into CF. Error: ColdFusion was unable to create an image from the specified source file. Ensure that the file is a valid image file. So I thought ok, let's try and pass an Imageformat to the Bitmap's save method. http://msdn.microsoft.com/en-us/library/aa903826%28v=VS.71%29.aspx I can do this: But if I then try to pass that to the Save method it errors again: The Save method was not found. Either there are no methods with the specified method name and argument types or the Save method is overloaded with argument types that ColdFusion cannot decipher reliably. ColdFusion found 0 methods that match the provided arguments. I'm banging my head now. I also tried imageformat.Jpeg but no dice. Element JPEG is undefined in IMAGEFORMAT. Any tips appreciated.

Dave, Do you know any common reasons why you might have to specify an assembly in this case? Because I can see System.Drawing in the GAC. But was unable to reference any of the classes unless I supplied a path.

Re: Back to .NET integration - Enumeration issue
Well as Dave said, System.Drawing.Bitmap descends from System.Drawing.Image. So it should have access to everything in the Image class. Since you already have a reference to a Bitmap, try using it instead. > Do you know how to instantiate System ddls? > class="System.Drawing.Image" Well technically you do not instantiate an abstract class. That said, creating a reference to System.Drawing.Image works fine for me. -Leigh ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:338850 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

You can't instantiate an abstract class. Think of Image as being somewhat analogous to an interface in AS3. But in general, if you have a non-abstract class in System.*, you should be able to instantiate it without specifying an assembly path as it'll be in the Global Assembly Cache.

Back to .NET integration - Enumeration issue
Hi all, I'm back working with the Aspose .NET ddls and have a question. First I do this: Now in order to save this presentation in another format the docs state that I need to do call the Save method of the Presentation class. It accepts two parameters, a string describing the file location, the second is constant described by this class: C# public enum SaveFormat Members Member Name Description Value Ppt Save presentation in PPT format.0 Pps Save presentation in PPS format.0 Pdf Save presentation in PDF format.1 Xps Save presentation in XPS format.2 PptxSave presentation in PPTX format. 3 PpsxSave presentation in PPSX format. 4 TiffSave presentation as multi-page TIFF image. 5 Question: How do I use this in CF? I've tried the following: and but both throw errors: "The Save method was not found. Either there are no methods with the specified method name and argument types or the Save method is overloaded with argument types that ColdFusion cannot decipher reliably. ColdFusion found 0 methods that match the provided arguments." If I dump an instance of the SaveFormat class I see this: Field Value Aspose.Slides.Export.SaveFormat Pdf Aspose.Slides.Export.SaveFormat Aspose.Slides.Export.SaveFormat Pps Aspose.Slides.Export.SaveFormat Aspose.Slides.Export.SaveFormat PpsxAspose.Slides.Export.SaveFormat Aspose.Slides.Export.SaveFormat Ppt Aspose.Slides.Export.SaveFormat Aspose.Slides.Export.SaveFormat PptxAspose.Slides.Export.SaveFormat Aspose.Slides.Export.SaveFormat TiffAspose.Slides.Export.SaveFormat Aspose.Slides.Export.SaveFormat Xps Aspose.Slides.Export.SaveFormat Any tips appreciated.
