I know that various settings will affect the height and width numbers when you get around to rendering, but I want to be able to always know when I'm working with, say, a 720x480 "real" frame. You can always multiply the input or output images by the scaleX and scaleY, but I don't think that's what you mean. What are you trying to do? There really is no "real" or "full" frame size. Remember that the user could be applying your filter to a group, replicator, or particle system and the "real" size can change on a per- frame basis from 0 pixels to anything larger than that in both dimensions. Also, there could be other filters which change the size in odd ways, applied before yours. This email sent to site_archiver(a)lists.apple.com

I read a post at http://cocoadev.com/forums/comments.php?DiscussionID=612 and wonder if it is not possible to make current Cocoa apps behave like the Finder. Is it still valid to use NSCreateFilenamePboard() function? When I used a returned string by calling the function, the Drag&Drop informaiton is quite different from that from the Finder. Even when I try NSURLPboardType with declareType.., it didn't generate matching "fURL" flavor. And it doesn't seem to me that it is possible to make "hfs" flavor also. With NSFilenamesPboardType, it can generate the "fURL" and "hfs" flavor, though. Should I use some Carbon calls? -- My previous post.. -- Hello. I found out that NSCreateFilenamePboardType() would help. So, I tried it like : NSString *quicktimeFileNamesPboardType = NSCreateFilenamePboardType(@"mov"); [myNSTableView registerForDraggedTypes:[NSArray arryWithObject:quickTimeFileNamesPboardType]]; NSString *quicktimeFileNamesPboardType = NSCreateFilenamePboardType(@"mov"); anIndex = [selectedRowsIndexSet firstIndex]; while( anIndex != NSNotFound ) { fileName = [NSString stringWithFormat:@"%@/%@.mov", configPath, [[dataArray objectAtIndex:anIndex] name]]; [fileNamesArray addObject:fileName]; [pboard declareTypes:[NSArray arrayWithObjects:quicktimeFilenamesPboardType, nil] owner:nil]; isSuccessful = [pboard setPropertyList:fileNamesArray forType:quicktimeFilenamesPboardType]; When I check what information is exported from my program with the Drag Peeker X, it shows : Is there anything wrong how I use the NSCreateNSFilenamePboardType? How to use it properly? P.S. By the way, is it normal to put 'furl' and 'hfs' flavor when NSFilenamesPboardType is used? Because an array of file names are added to the pasteboard, I thought that only file name strings were added. But it turned out no-so-true. JongAm Park wrote: Thanks to a utility program, called DragPeeker X, I found out some clue why the FCP treated dragged file as a file with unknown type. ( I also tried NSURLPboardType and NSFileContentsPboardType. But they didn't make information like above appear. ) The PboardType I used was NSFilenamesPboardType. What actually matters, I think, is the data of the 2nd flavor. The one using the Finder starts with MooV????, which says that the dragged item is a QuickTime movie, while the one from my application doesn't contain anything. ( all 0's. ) So, is there any way to mark that the interested file is in a specific type, i.e. QuickTime movie file? This email sent to site_archiver(a)lists.apple.com

(As I said earlier, it's not as complete as we'd like.) Here are a few more answers inline: I read that the motn file is an XML file so i've been experimenting with it and found that there are factory tags that appear as soon as a scene node is created. These factory tags have UUIDs in them and they seem to come from a constant list of UUIDs or something. Is there a way to predict what the UUIDs will be? or do i have to add stuff in motion to try get the factories to appear in the XML document? Yes, and yes. They will be constant (they are Universally Unique IDs because we don't want them to collide with any other IDs). To figure them out, it looks like the easiest way is to create a document containing the various objects you want your app to create and copy the UUIDs from there. also, are the id attributes in most tags random numbers? or is there a specific range that they have to be in? I believe they generally have to be in a specific range. I'll have to do some digging to figure this out. (Off the top of my head, I seem to recall they have to be over 10,000, but I'm not positive.) say for example some parameter such as color has the tag <flags> with some four digit number while the flags for the colour parameters are only two digit are these numbers random (but consistent between related parameters)? I'm not positive I understand the question. The flags should all be 32- bit unsigned integers. Looking at them in hex will probably make them easier to find patterns in. They should be consistent in the sense that any given parameter has the same flags that it can set or clear. But different objects' parameter's may have different meanings. if i have a program to generate the motn files do i have to worry about the flag values? what are they, and what is the difference between foldFlags and flags? The flags and foldFlags are generally not documented. I'll have to see if it's safe to set them to 0 initially or leave them out. FWIW, foldFlags will generally refer to a folder containing other parameters, whereas the flags generally apply to the individual parameters. Some parameters (like a color swatch or point parameter) are actually folders of more parameters (RGB&A for color, or (x,y) for points). I'll see what info I can find that will be of use to you.

Otherwise, Final Cut will crash when reading a project that was created with the previous version of your plugin. We're aware of this problem, and plan to fix it in a future version of Final Cut. I believe at one time, at least FCP I think, FxPlug IDs were not being honored, and in order to support backwards compatibility from one version to the next, you had to be sure to add all new UI at the end of your plug-in. Is this still the case? We're about to do a big update and this would be a bummer. There were a few issues that Paul could probably enumerate better than me. (Not sure if adding parameters works or not in FCP at this time.) However, nowadays, we do have the FxVersioning API which we make great use of internally. If you didn't include a version number in the Info.plist of your previous plugins, then documents containing instances created with the older versions will have a version of 0. If you add or increment the version in the Info.plist file, instances created with the new version of the plugin will return the new version number from the [FxVersioningAPI versionAtCreation] method. So you can tell if an instance was created with an older version or a current version. This email sent to pschneider(a)apple.com This email sent to site_archiver(a)lists.apple.com
