I believe the Details tab is giving you the correct info - your image is 19200 x 15360 pixels at 1200 dpi (or 16"x12.8") - I don't know about the IMAGE tab. I run Windows Vista and I don't have such an animal on my File Properties window.
You question is actually very confusing and contradicting - you said you needed 12"x12" output, however your export dialog is set to 16"x16". Then you mentioned twice 300 dpi, but you said your program can only read 200 dpi. And again, your export dialog is set to produce not 200, not 300, but 1200 dpi!! You need to get your story straight, man!
Simply put, if you need 12"x12" at 200 dpi, set your export settings accodingly (well, that's kind of obvious, isn't it?).
This should produce the output file of 2400x2400 pixels.
Vladimir, Thank for the reply,
1st I believe you are correct about the Details Tab - but somehow to Windows (I am also using Vista Ultimate) and other programs are using the 200x200dpi designation under the Image Tab.
Let me clear up my confusing question too and see if this helps.
After developing I go to export and enter the following parameters (as suggested)
Then in the properties of the exported file I get the following.
Notice how in the DETAILS tab I get the parameters I specified (300ppi) and yet in the IMAGE Tab the file is denoted as 200ppi.
no matter how large I specify the file it is denoted as 200x200ppi in the image tab and thus when I open it in any other program it is read as 200ppi.
I have also opened the file on an XP system and I don't get the details tab in properties only the Image tab and the status is the same (200ppi)
Does this make sense to anyone?
I am guessing the "JPEG Summary" and "Image" tabs are supplied by some 3rd party software, and not by Vista.
For that reason, I would be cautios about relying on the displayed information. I spent a few minutes googling for "JPEG Summary" +tab, and I couldn't find anything that would indicate the source of that tab.
I still would rely on the information displayed on Details tab (exists in Vista only, not in XP) - it looks accurate.If you are still unsure, download IrfanView - a an excellent free image viewer. You can press "I" for image information when viewing your image in IrfanView and check your image dimensions and DPI that way.
I doubt that it is third party, however I am going to look into hoe Vista handles images. There may be some variables hidden there.
I down loaded IrfanView and when I opened the image and checked properties I got the following.
Notice the DPI boxes are empty. This is the way it opened. Anyway, I'll figure it out. One thing I did notice is that when I exported at a higher resolution the filesize would be larger, and then in the image tab the resolution would stay at 200x200 but the size of the image would be larger by the factor of whatever my desired output/200. example. If I exported at 8"x12" at 400ppi the result in the Image tab would be 16" x 24" at 200x200. I don't understand this. I sort of get the desired out put but not really.
