Affinity Designer - How To Decrease The Image Size By A Particular Scaling Ratio?

[Mainecoon364]

For example I want to decrease the image size by %20.

 

How can I do this?

[Oufti]

To modify the size of an image, you select it and, in the Transform palette, you link Length and Height. Then you can type the ratio you want.

For example, if Length was "100 mm", you type "100 mm * 0.8" and it is scaled so that it will measure 80 mm.

Embarrassed to ask, but where is this?

Sorry, I believed the original post was related to Photo. (Where it can be found here: Document -> Resize Document)

But the percentage trick also applies to Designer in the document setup dialog:

You may have missed that this is an iPad question.

I'll also guess that it is a V1 question, given the user who asked it  

@Mainecoon364: please clarify what you mean by "image" in your question. Do you want to resize a document, or an Image that you Placed into a document? Or if that's not it, can you provide a screenshot to clarify the question?

No worries, but really got me searching for such a dialog in Designer!

[Mainecoon364]

Sorry for not being clear enough.

 

I want to decrease the size of the image which I select via Move Tool by the Ratio of %20.

 

On

 

A) Affinity Designer Ipad v1

 

B) Affinity Photo Ipad v1

 

?

Still, what do you mean by "image". You could mean an image that you have Placed within your document. Or you could mean the document itself. Or something else.

If you mean the document, just search the Help for resize: https://affinity.help/designeripad/en-US.lproj/pages/GetStarted/resize.html

[Mainecoon364]

An image placed within my document. Not the document itself.

 

How can I scale It by %20?

Use the Transform Studio on the iPad 

[Mainecoon364]

“Red Sands” that must be Affinity Designer PC version. I use It on Ipad.

I assume I calculate the %20 and decrease the height and width there.

 

Right?

 

It looks like there isn’t a place to enter a scale value.

If you watched the video you saw that you can use calculations in the dialog, and let the app do the arithmetic for you.

• Image properties like those from my previous screenshot is sorely missing in Affinity for iPad
• Serif, don't force people to make calculations to obtain a percentage value, this is not SuperCalc 5 for DOS.

Look at my iPad screen recording showing the details you say are missing on iPad, they are in the transform studio unless you mean the trivial % box which is no miss on the iPad.

Look at my iPad screen recording, Serif don’t force people to make calculations, you can scale by multiplications divide add subtract and even enter equations directly in any number entry box on both iPad and the desktop, unless this is what you mean, can’t see how mind control could ever work.

I think Red Sands is suggesting, as others have over the years, that a direct "scale by <some percentage>" function would be nice to have in the UI, as some other applications have.

Also, on the desktop, you can simply type 80% in the height or width box, without needing to enter a calculation at all. I'm away from my iPad so I can't check right now if that works there, too. But if not, it would simplify things.

But the point raised by Red Sands and others, I think, is that this ability to use percentages (and other calculations) is rather hidden, and most users don't know it exists. They look at the dialog expecting some percentage function, and it's missing.

Thanks Walt !

As an aside though what a sorry state of the education systems that people don’t relate multiply by 0.8 exactly the same as 80%. 

As for other apps having better methods, I await the screen shots of equivalently comprehensive applications on the iPad for comparison. 

[Mainecoon364]

As far as I understand there It is no possible now.

 

So I assume I need to calculate of %20 of height and width values and add them.

No, let the app do the hard calculation, you need to do the easy calculation 100%-20% = 80%.

I.e. Reducing by 20% is the same as reducing the image to 80% of its previous size.

80% is the same as multiply the existing height and width by 80/100 = 0.8 as shown in my screen recording above. So the only data you need to enter in the numerical box is 0.8.

So the only data you need to enter in the numerical box is 0.8.

But you can also enter all the calculation you want. 

For example, you could type in any size field something like "24 pt – 20%" (= 19,2 pt) or "2 * (24 pt + 6)" (= 60 pt), if it is easier for you…

As several people commenting here, this is the iPad version not the desktop version which unfortunately does not have direct equation entry BUT can still use a pop up calculator on every number box instead. Your examples would be done by  x 0.8 and +6x2.

I’m using Ipad version.(Your version looks like different ui than mine)

 

Is there a place where I can enter the value of %80? Where?

 

I missed that point.

More specifically, you're using Designer V1 on the iPad and it's important to keep saying that (or to update your forum signature, though that won't help users who view the forums with a phone or small tablet). @Paul Mudditt used V2 in his video.

That aside, I don’t think the Transform Studio behaves differently in the two versions. Tap on any value in the Transform Studio to make the pop-up calculator appear.

V1 iPad screen shot showing how to reduce by 20% = 20/100 = 0.2, 1 - 0.2 = 0.8 = 80%

Thank you very much for the answers.
