I have 1 jpg file. Size = 1.10MB. Dimension = 3630 * 2466.

I resize it with using either blit or resize function.

Both of 2 is resized. But it changed the properties of image.

Original image bit depth is 24, no compression & no resolution unit.

But, resized images becomes depth is 32, LZW compression & resolution unit is 2.

Really, I don't want to change the properties that described in above.

When I resized with Paint it doesn't change the original properties. (only size and dimension are changed.)

How can i do? Please help me.

Thanks & Regards,
