Designer: scale image to same dpi as document / 100%

[bediicco]

If i have a document set to 300 dpi, is it possible to scale an image directly to fit the dpi of the document / 100%?

 

I can view its calculated dpi in the source viewer, but how to set it directly to 100% based on the documents dpi?

 

This way it is trial and error to stop at 300 dpi.

I'm not sure I understand what you're trying to accomplish. 

A couple of choices, for example:

• It's easy to make it 300 dpi. Just Rasterize it, at whatever size you prefer visually for your design, and it's the document dpi. If that's 300 dpi, then you're done. 
  or
• (Working in round numbers for simplicity) In your Resource Manager screenshot your Placed image is 142x231 mm at 150 dpi, do you want to make it 71x115.5 mm at 300 dpi without rasterization?
• Or are you trying to do something else?

For the second one (and using your actual values), in theory you could calculate 152/300 = 0.506666666666667 and in the Transform panel, with the Move Tool active and that layer selected, you could make sure the aspect ratio is locked between w and h, tap the w field and type (times) .506666666666667 and you should have the right size. In practice,

1. That won't be exact and you might not hit exactly 300 dpi. 
2. There's an unfixed bug in the iPad apps that won't let you enter the "." into the calculator field in the Transform panel. So this approach won't work at all until that is fixed.

Note: If you were using the desktop apps, not the iPad, there are additional possibilities.

I know how to calculate that. If you create collages and illustrations, you don't want to calculate something for each picture that the program can do. If I place the image, I can either resize it or place it in its original size (i.e. at 300 dpi) - this is where Designer already has the functionality. I just wonder why it is not directly available as a button.

I don't understand the rasterize context. So basically in the middle of my work I just want to see how big the image actually is in the original, if I render it like the document itself in 300 dpi.

thank you for your calculations @walt.farrell

I think other users probably misinterpreted your request. No need to rasterize or make any calculations 

the easiest way to restore the original size of a placed image is described in help:

That's the desktop Help, and we're discussing the iPad.

I don't know why, either.

As you mention, you can get the function you want by tapping the screen rather than dragging. But that's the only it's provided on the iPad versions. The desktop version has the button you want, but not the iPad.

Unfortunately, this is the difficult thing, that sometimes the space in the UI is missing and that sometimes it is simply not implemented, although you know it from desktop (so it is just irritating if you do not have a desktop side by side to check)

Ok yes for desktop, thank you nevertheless

If you cannot find information about a function in the Help, that is a good indication (though not perfect) that it doesn't exist. Sometimes, comparing the Help for the desktop and iPad can reveal that, if the desktop Help shows a function and the iPad Help doesn't.

On iPad it is in transform panel to show layer dpi or scaling %. Just enter 100%. Look in iPad help for move tool / transform panel.

DAMN!

You are right!

But % is only available if you change this red marked button (didn't know that this is a button) Without i had only values mm, cm, m, px, pt, in, ft and yd.

Thank you!

@walt.farrell when changing via this button above, you can double click the % number and it jumps to 100% cheers 🙌🏻
