I have a SG set up with a large graph constraints of say 2550 px in width and 3300 px in height. There are object(s) top left and bottom right. I would like to save the SG as a machine independent representation. So using what is available in terms of file formats (meta file, bitmap, component streaming) the only one I can use is TBitmap that is machine independent. However with the size of the SG the Delphi TBitmap gets an EOutOfResources error when it attempts to save such large bitmaps (This is because http://www.efg2.com/Lab/Graphics/VeryLargeBitmap.htm
So has anyone got any suggestions on how I can save a SG with these dimensions as an image of some form BMP, PNG, GIF etc.? If this makes use of third party components then so be it - I would just like to see some code examples and ideas if anyone has any.
