What is the compression limits in terms of image size that can be achieved with different license level of GeoCompressor? I understand Essentials - 250 gigapixels, Advantage - 500 gigapixels and Professional - unlimited; what is the interpretation of this in terms of Megabites and Gigabites?
Also can ECWJP2 SDK read-write version perform compression quivalent to GeoCompressor professionals?

for example, for input image 10000x10000 pixels in heigh and width, the number of pixels is 100,000,000 = 100 Gigapixels
if the uncompressed original/input image is 3 bands (RGB), 8bit, then the size of the image will be 100,000,000 x 3 x 8bit = 2400000000 bit = around 286 MB
Geocompressor use ECW JP2 SDK internally, so the SDK RW should have the similar performance as geocompressor.
