How can I downsize a picture proportionally?

[Markus W.]

Hi, I am a new user of Affinity Photo and searched i a lot of tutorials. Maybe someone can help me:

 

I do have a picture. I am going to select a part of the picture by using the sniping tool. But how can I use the sniping tool that the proportion of the picture will stay the same? 

Is anybody having a hint where to find a tutorial video which is relevant to this topic? 

 

Thank you.

Hi Markus W.,

Welcome to Affinity Forums

Se the Mode (Modus) in the context toolbar to Original Ratio (the second option from the leftmost dropdown).

This is not what I mean. 

 

I do have a picture. I want to cut the picture by using the sniping tool as shown on my upload. But if I use the sniping tool manually, the proportion of the picture will get lost if I am downsizing the picture 9x4 cm for example. So let me put it this way: I want to select a certain area of the picture and cut out this area. But the selection process should keep the proportion of the picture.

Bonsoir.

Mode -> Dimensions absolues -> Unités (centimètres etc ...) -> se renseigner dimensions choisies -> Entrée. 

Dimensions absolues -> Ajouter un préréglage -> OK  enregistrera les dimensions réutilisables.

Hello Markus,
There are three Option to crop or resize a picture.
Option 1: is cutting with the crop tool, everything outside of the frame becomes cut away.

Option 2: Change the document size with the command CTRL+ALT-I, the complete image content is retained

Option 3: Create a selection with rectangular marquee tool, the exact size of the selection is determined
               in the panel Transform. With the shortcut CTRL + ALT + SHIFT + N, can you a new document  from the clipboar create.
                               
I hope it helps you.
