Why is the image quality so low although "lossless" is selected in settings?

Correct answer Jorma_at_Knox

I used the image you provided and published three versions of it via Presenter 8.0.1.

The lossless setting for image quality produced the worst result.

The High Quality setting produced the best looking version of the image (and the largest file size oddly enough).

The Medium quality setting produced an image that seemed acceptable, but noticibly lower in quality than the High setting.

I'd use the High Quality setting as that seems to yeild the best result for this image.

If you are bringing an image into PPT and the forcing it to a smaller size (or larger), then you will have a quality loss due to the rescaling of the image. No quality setting can fix this.

Use a program like PhotoShop to properly re-size the image and then bring it into PPT once it is the correct size. You should see an improvement in quality and a reduction in file size.

Dear Jorma,

I tried several options. Reducing the size improves the quality a bit.

Please see the answere I wrote to Vikram including the links.

Thank you

Hello,

Welcome to Adobe Forums.

Which version of Adobe Presenter are you using ?

Which version of MS Office do you have ?

Are you inserting an Image or Copying it ?

Please elaborate your query, mention the workflow you are following.

Thanks,

Vikram

Dear Vikram,

I used Presenter8, Win7, 64bit and Office 2010 all with latest updates.

Copying the image to Powerpoint or using the insertion procedure does not make a differnence.

Please see the exported presentation

and the same presentation exported as pdf with good image quality
