How to do Proportional Capture

  • 1
  • Question
  • Updated 7 months ago
I am collecting several screenshots that will need to be scaled to a specific size. I'd like to capture the proportions rather than a fixed size. Rather than 500px by 250px I'd like 2:1 so that I am constrained in my selection. Is this possible? (I know I can change and fiddle with this later, but it would be great to simply capture in this ratio.)

As far as I can tell, when capturing a region, Ctrl+ drag gives a fixed widescreen ratio and Shift + drag a square ratio.  I suppose what you're looking for is something like an Alt + drag combo that is user definable?

You can create a preset to scale an image either to one dimension or the other or to a specific size
Either from the red button at the top or the orange tray icon ... choose "manage presets"
Then under EFFECTS chose "scale image" and set the paramaters
If that works, assign it a hot key and you are good to go

You can constrain the capture area by also choosing under "selection" "Region and click the geat to the right to choose "fixed area"  then define the area

You are going to have to play with this a bit

"Fixed Region" only allows pixel dimensions. I need a ratio.

Also, I don't have "Scale Image" under effects. Using the Image Resize and Canvas Resize is too much work.

Ah, I was looking in the Editor, not the Capture Window. The problem is that I don't know "how much" I want to capture. That's why I'd like the capture to constrain the proportion. This looks like crap.

I presume if the image you wish to capture isn't in the desired proportion, you want to capture extra surrounding information rather than distort the aspect ratio of the thing you're interested in?  I don't know if you're familiar with Photoshop, but something like how the crop tool works if you preset an aspect ratio?

Yes, like constrained ratio in PhotoShop.

I assume that the Ctrl and Shift + drag combos work on the basis that the x axis is defined as a fixed percentage of y.  If that's the case, then allowing the user to define the relationship, and then using that in the existing code should be another case of low hanging fruit.

But again, that's no guarantee......

Sure seems to me that you could just define a preset using Region. Then specify the ultimate size you want.

I'm guessing that the reason this won't work is because you will be scaling things after you capture to fit that size?

Right. Even though they want 500x250 I want to capture 1500x750 (Or whatever looks good) and then resize it to 500x250.

Hopefully you are aware that while it "looks good" at that larger size, it will suffer degradation when you rescale to make it smaller.

Beat me to it.  If they want 500 x 250 there's little point in capturing larger and down scaling.  Pixels will be discarded.

Paul, I was using that as an example. Twitter uses a similar size. I'll keep using PhotoShop.

I found one awkward way of doing it, but I'm not sure it will help.  If you want, say, 500x250 in the end, you can start in the upper left of your desired area, and make a 500x250 (or 250x125) selection, then hold Ctrl while dragging down and to the right to preserve that aspect ratio.  It's pretty finicky just getting that initial ratio, though if you use the arrow keys you can move one pixel at a time.

Interesting, though as soon as I have the selection and click the CTRL key the selection grows by 6 pixels. It's does not stay where I put it.
