export using lower dpi - unexpected result

[sagiSpin]

hello, i have a png i want to export from flash
if a export the using 72 dpi and than rescale the image to bet 25% of its original size i get a result image A
if i export the using 18 dpi (72/4) i get a result image B
both A and B are now in the same size
but B looks much more pixelated

(smoothing has no effect on the result of B)
is there anyway i can configure flash to result higher quliaty image B?

i do not want to use a third party program to rescale.
low res export, also happend if i rescale inside flash 25% and then export

It's from Flash era, but as far as I know it still applies.

"Don't scale imported bitmaps within Flash, which can greatly reduce image quality in published SWFs. Rather, use an external image editor such as [Adobe Photoshop] to scale the image to the desired pixel dimensions before import."

Improving bitmap image quality in Flash

If you have Photoshop, the best you can do is to open your bitmap in Photoshop from within Animate CC and resize the image there.
