Just a note on bigtiffs

[DandroidDeveloper]

The majority of bigtiff testing I have done is returning incorrect values for the stripOffsets.....

If anyone in the future needs the correct values for rendering data, you can just reference the first stripOffset (where your raster data starts), and then add (row * ImageWidth * 4), to get the correct value.
*assuming they are float32

Hi @DandroidDeveloper

Thanks for reporting this issue! The files I worked with could be displayed without error, do you have test files available that did not work so I can reproduce and fix the error?

Unfortunately no :/

The behavior I saw was with bigTiffs that I am 100% sure are created correctly and have correct metadata. Most of the stripOffsets are correct, but maybe 30% are negative values when accessed using the library.
