This bug has been around for a while.

You take two captures.  Then you drag one onto the canvas of the other and this happens - see the poor quality of the dragged image on the left?

It occurs when one of the screen shots is larger than will fit on screen, so you select Fit on screen.  Then drag the smaller image onto the reduced canvas and the quality of the dragged image  goes through the floor

Hmmm, I'm not sure I've ever seen that. I just tried and cannot reproduce on my own setup.

Curiosity point. Do things clear up once you return the image to 100% of full scale?

It's happening now, big time.  Ticket opened with Support because this is starting to get in the way of work

If you want to see the effect in action, go here

I see in your video. the canvas re-scales itself to 80% in the viewing area as you place images outside of the canvas.
If you set the scale of canvas back to 100% "Actual Size" is the image Clear again?

Spot on Joe.

Unchecking "Always shrink to fit" stops it from happening in the first place.

So now we know it's related to scaling.  Good.  That will make fixing the bug easier

I think you'll find it's not a bug at all. It's SnagIt being itself.
You should find If you save the image. It will be crystal clear at 100% zoom level.

SnagIt doesn't re-scale  image on the canvas nearly as well as Photoshop does.

That's one of the "BIG" reasons I'm a Photoshop guy and don't like editing in SnagIt.
I hate working on blurry and/or distorted images.

Photoshop can't scale things "Downward" endlessly without losing clarity,  so don't misunderstand what I'm getting at. It's not hard on the eyes like SnagIt is.
Here's some examples.

SnagIt


Photoshop


Rendered Image

Don't HAVE Photoshop, don't  WANT Photoshop, just want Techsmith to fix it. :)

If it's not a bug but by design, it's plain daft.  If you are going to degrade it why not degrade the whole thing.

Plus, why degrade the thing at all if the user places a smaller item on a bigger one.

Well, I got your answer and your either gonna hate it or like it.Or both?

The images aren't rasterized. If that's the proper terminology here.
That's why they look like crap. Apparently SnagIt can't give you clean previews of copied and pasted images."Dragged in Images" that have been re-scaled UNTIL ...................
Wait for it.......................You flatten them.

So you've got to live with the eye sore of degradation or commit to flattening to get around it. Plus, hope you don't change your mind.  Decide you need to move the image.

Yet another good argument for a layers panel.With layers, you just select a layer and move it.Or shut it off it it's bothering you.
I would prefer SnagIt was just better at editing images and it didn't do such a poor job of scaling.

I can tell you that SnagIt 10 and 11 aren't afflicted with the same problem. That doesn't change the fact that PS does a better job of re-scaling images you are working on.

I'm all for giving SnagIt the benefit of a doubt and attempting to be accurate instead of dead wrong.
That's why I tested version 10. Uninstalled it and installed 11.

I jumped the gun on this one. I had version 10 installed and should have tested it as well.Before I responded initially.However, I believe I identified the problem.

I think you may mean "vectorized". As I understand it, a raster image is one composed of pixels, or PIcture ELements. While a vector image is one composed of many thousands of instructions to the computer of how to draw the image.

Raster images always degrade when the size changes while vector images are crystal clear at any scale.

At least that's how I've always been told it is.

Cheers... Rick :)

You are Incorrect.

  In PS you can convert images to "Smart Objects"
It's been that way for several years, you can re-scale or change an image "Layer" any way under the sun. Countless times, over and over again. The image will not be degraded in the process.
The image is rasterized automatically when you save it as a png,jpeg etc.

I wasn't putting any effort into addressing the proper term. It would have only taken me a moment to do so. I was being lazy and settled for "If that's the proper terminology here"

However, At least I invested the time to cover the actual problem.
I could have opened Photoshop to remind myself.  Checked the menu to see that you "Rasterize" Images. I knew that in the back of mind. That really wasn't the focus of this thread.

Well, it seems to me that you were saying here: 



that the images looked like crap because SnagIt  has no way of creating vectors from raster images. If they were vectors, they would look clearer, no? Crystal clear, in fact. At any scale.

LMAO... Rick :)

Raster / vector - all very interesting but let's get back to the point.  Whether it's by (lack of) design or a bug, SnagIt allows you to drag one image onto another.  If it allows you do that it should do it right.  If it can't do it right, it shouldn't give you the option to do it.

And if 10 and 11 could do it correctly, why can't 18

Exactly, Ricks just here to cherry pick an attack on me. I'm used to it.He had no input to the actual problem at hand.
Congrats Rick, you caught me off my game.
 I didn't sleep a wink last night due to some other issues and I probably shouldn't be contributing to the forum at all today.
I'm out of here for now.

Paul, I agree with Joe that SnagIt is just doing its thing. 

Admittedly, I looked at the video you supplied and I'm stymied as to being able to see anything that isn't out of the ordinary.

I think the gist of this discussion is that any viewing of images in the SnagIt editor is going to be less than optimal when the zoom setting is at anything other than 100%. And I believe in other threads I've linked to the TechSmith video demonstrating what happens when scaling of raster or bitmapped images occurs. Bottom line is that they degrade in different ways.

I would have to say that I disagree with the viewpoint that it's a bug. Personally, I view it as expected behavior when dealing with bitmapped images. 

Since I'm here and I recall seeing you post about another visual oddity, the blue line artifact on the image, I will also advise that this happened to me personally yesterday. The snap line appeared, then remained. As it turned out, it was just a visual oddity (likely related to the video card and the screen painting) because even though it was clearly visible in the editor, it wasn't saved in the final image. Distracting, to be sure, but not harmful either.

Cheers... Rick :)

No Joe, no cherry picking or any kind of a personal attack. I'm not sure why you feel it was. It was only a clarification on an inaccuracy.

OK, so here's my suggested fix, which requires nobody to worry about rasters or vectors or bitmaps or any shit like that.

If user drags image from tray onto another image on the canvas and places it outside the existing canvas perimeter and "Always shrink to fit" is option is off, turn it on before placing the image on the canvas and turn it off again when you are done.

You just now got around to addressing the topic at hand.Rick,
It took you over 2 hours to address the issue.Yet, you saw an opportunity to  correct me immediately.Jumped right on it. Stayed with it relentlessly, that's personal in my opinion.

Your still out of the loop with the response you've posted . I've proven the issue doesn't exist in SnagIt 10 or 11. So it sounds like a bug to me.
