Images in Flash

[LeadMagnet]

When publishing your SWF, Jpeg compression of embedded images is absolutely terrible quality (artefacts all over the place).

If the images you import into the library are already Jpegs (exported from PS) is there a way to get flash to NOT recompress them again?


I know i could reference an external Jpeg, but it's often more convenient to have them embedded.

are you sure your not resizing the images inside flash?

If your not, right click on the jpg in the library, you can edit its properties. and increase the jpg quality.

No, not resizing anything. Let me show you an example.
This was a small job i did just the other day.

All the images: Index of /buick

The final flash app: buick
(press Space if you want to see the flame car easter egg)

The jpeg images in that URL above were all exported from photoshop at 80% quality.
Embedded into the flash file and then published.

jpeg setting in flash is 80% also, but that's not relevant because even if i set it to 100%, it's still re-compressing the already compressed jpegs into 100% quality ones. They retain the same quality as the photoshop exports at double the file size.

Flash jpeg @ 80% is shocking compared to Photoshop jpeg @ 80%, have you never noticed that?

I even tried importing the PSD directly into Flash to avoid 1 of the compressions at least, but the difference was negligible. The images had all the same artefacts as before and the file size decreased by 2kb.

For anyone that's interested, i accidentally stumbled upon the solution to this today.
Only import Jpegs that have been exported using the 'Baseline standard' or 'Baseline optimized' algorithm. That way you'll get an option (it will be turned on automatically) that will let you use the imported jpeg quality instead of re-compressing it.

Progressive encoding seems to not be liked by flash.

thanks for that, I will try it next time the situation arises!
