We are trying to resize from J2k to a smaller 'Thumbnail' JPG version, but when we do, we lose tons of quality. We think its the resize that causes the image to lose quality.

We are using LeadTools ActiveX32Bit 12.1

Here is the code we are currently using.
.Size 80, 100, RESIZE_RESAMPLE
I have examples of J2k Images, vs the .JPG Files after conversion if needed.

Thanks for any help in advance,
Cavin

Cavin,
Is the loss in quality visible in the displayed image before you save it, or after you save as JPEG and load it again?
If it's after saving, try to use a smaller value for the Q-Factor parameter in the Save method to improve JPEG quality.
If it's noticeable before saving, please put both J2K and JPEG images in one ZIP file and post them here or send them to support@leadtools.com

Wow, Thank You!

We never thought about lowering the Q-Factor. Higher number, higher quality... at least thats how our minds were putting it.

Thank you so much!
