Images imported to Keynote get automatically downsampled, although downsampling/resizing is unchecked

Hi!


We encountered a problem on Keynote 6, we don't have, using Keynote 0.9. Sometimes we need to import really large Images into our slides, to demonstrate webdesign to our client. We have to handle some really big images.


We are not using the downsampling (fitting size of pics to slide) feature built in Keynote, because, showing designs, we need crisp pngs with neat quality.


We tried to import one picture with 4400 px height. Keynote kept downsampling the image, no matter how we tried to import, paste or drop it. Cutting our PNG to about 3000 px height helped, but we really need to import it in its original size 4400 px.


Having a look at the filename in the format panel, we discoverd keynote adds a "-small" to the filename, leaving us with images with the name "image-small.png". Replacing it with the bigger picture inside the Keynote zip didn't help either. We definitely unchecked the downsampling checkbox in the properties, but the filename indicates, he downsampled it anyhow.

Now we are really frustrated with the Keynote 6 version. It kept bugging us with other little pixel errors, like not allowing us to position pictures on one precise pixel numeric value. But having blurry pictures in a design-based presentation forced us to go back to Keynote 0.9, which handles our large image just fine.


Anybody encountered some similar issues?


We're quite clueless now.


thx, Silke.

Supplement: we noticed, that the threshold seems to be the magic height of
4096 px, which would be 2^12. Having a height of 4097, the image gets downsampled. Using a height of 4096 and lower, the image keeps its quality.


This sounds to us like an intended limit. Anybody who can confirm that?


Greetz, Silke.

Your post saved my presentation!


We had designed a website that uses a long scrolling page and we like keynote to help animate and bring it to life. With the upgrade to 6.1 the images in our presentation were looking really bad and downsampled.


Using your info, we saved out our JPGs at no greater than 4000px and then grouped them in keynote to make a long scrolling page. It worked, but defeats the purpose of drag and drop presentation creation that used to be the hallmark of keynote. It's a total workaround solution for a problem that wasn't in any other version of keynote that I've ever used.

I found a solution that prevents Keynote from destructively downsampling your images. Using the example of a long website comp, just save the comp as a flattened PDF directly from Photoshop. The PDF keeps all its own metadata concerning resolution and size when dropped into Keynote. I am including an example screenshot below. Notice the button. On the left is a PNG and a PDF of the same comp on the right. I should also mention that I have not found a height limitation to this solution so it shouldn't affect those long website comps you want to animate during a presentation.
