CollectionFS

CollectionFS

Usage - images example

Meteor.method

Note I have a normal Panel collection and a normal Images collection, and then CollectionFS collection is called ImageFiles.

'SaveImageToPanel': function(params) {
        var panel = Panels.findOne(params.panelId);
        // can't do shit without the panel to attach it to
        if (panel) {
            var decodedBuffer = new Buffer(params.imageData, 'base64');
            var newFile = new FS.File();
            newFile.name('panel.jpg');
            newFile.attachData(decodedBuffer, {type: 'image/jpeg'}, function (error) {
                if (error) throw error;
                var imageFile = ImageFiles.insert(newFile);
                //create a new image object to encapsulate this
                var imageUrl = newFile.url({brokenIsFine : true});
                var newImageObjectId = Images.insert({"owningObjectId": params.panelId, "imageFileId": imageFile._id, "imageUrl" : imageUrl});
                Panels.update({"_id": params.panelId}, {$set: {currentImage: newImageObjectId}});
            });
        }
    }

The OS X client objective-C

This should be easy to convert to work in iOS also

- (void)saveImage:(NSImage *)image toPanel:(NSString *)panelId
{
  NSBitmapImageRep *bitmap = [[NSBitmapImageRep alloc] initWithData:[image TIFFRepresentation]];
  NSData *data = [bitmap representationUsingType:NSJPEGFileType properties:nil];
  NSData *encodedData = [data base64EncodedDataWithOptions:NSDataBase64Encoding64CharacterLineLength];
  NSString *encodedString = [NSString stringWithUTF8String:[encodedData bytes]];
  
  NSArray *params = @[@{@"panelId": panelId, @"imageData" : encodedString}];
  [_meteor callMethodName:@"SaveImageToPanel" parameters:params responseCallback:^(id response, NSError *error){
    NSLog(@"%@!", error);
  }];
}
