loading in an image from a bank

| Hi I'm try to read an JPEG image from a bank. This image can be anywhere in the bank, but i will know it start location and filesize. an example that works..
b:TBank = LoadBank("input.jpg")
p = LoadPixmap(b)
SavePixmapJPeg p,"output.jpg"
but what if there was a lot of other data around that image file. I want to do something like this.. but I know this doesn't work.
b:TBank = LoadBank("input.jpg")
bp = bankbuf(b)
p = LoadPixmap(bp[0]..bp[banksize(b)-1])
SavePixmapJPeg p,"output.jpg"
Any ideas anyone? |

I've noe sorted it with a BankSegment function
b:TBank = LoadBank("input.jpg")
p = LoadPixmap(banksegment(b,0,BankSize(b)-1))
SavePixmapJPeg p,"output.jpg"
Function BankSegment:TBank(bank:TBank,position:Int,length:Int)
Local des_bank:TBank = CreateBank(length)
CopyBank(bank,position,des_bank,0,length)
Return des_bank
End Function
unless there is another way? |

pixmap:TPixmap = LoadPixmap(CreateStaticBank(bankbuf(b) + imageOffset, imageSize)) |
