Subject: Enlarging image problems...


XoxoTree ( ) posted Sat, 23 September 2006 at 3:38 PM · edited Thu, 07 November 2024 at 6:58 PM

Hi There,

 

I am having a problem with a few formulas  that I have combined( on different layers) from “dma”  public files”.  I am using Ultra Fractal 4. I am trying to enlarge the image . After enlarging the image it looks completely different from the smaller image.  As if not all the layers were not enlarged. All the layers  are marked as editable. Both the smaller and the enlarge image shows that all are in the same location and have the same magnification. What am I doing wrong? Or is this some type of weird  formula that I am working with?

 

I am at lost here. I want the smaller image to be enlarge and to look the same. What am I missing here? Can you be of some help?

 

Good day and thank you for your help.

Therese

Hi Therese,

We could probably help a bit better if you saved a single layer with the problem you are concerned about, then put the upr in here.  I do know that there are a few formulae that do not scale properly, and perhaps you have found one of those.

I am hoping I understand you correctly and this is what you need. Thank you

Good day to you.

; Hi all, from DownUnder.
; I'm pretty new to this, having discovered UltraFractal in the last month or
; so but I've been having a great time exploring just what can be done with it.
; Please make allowances for my status as a beginner.
; My algebra and higher mathematics is pretty rusty (or non-existent) so I
; haven't got too much into that yet - but there's plenty of time I guess.
; It was a difficult to know when to stop (as you may gather from some of
; my comments) but heck, it seems there's no end to what you can do with this.

I think Tresamie meant your fractal's parameters, not the formula.

However, something like this came up on the mailing list before and if I recall correctly lines like

float h = #height
float w = #width

mean that the height and width of the image are used to calculate the results.

I tested it and it indeed looks different when you either change the image size or zoom. You could try writing the author and alerting him that there's a problem.

Ok I'll do this. Thank you for your time.

After examining both the formulas and the parameters, it's clear the problem is in the dac010 formula, which relies on #width and #height in its calculations. This is almost always a serious problem when trying to render images larger. You can either write to the author (David Cherry) and try to get a fix, or you can find another formula which does essentially the same thing, but scales properly.

Unfortunately it's not often clear, without looking at the formula source code, whether or not an untried formula will properly scale. It's certainly possible to use #width and #height in a formula in "correct" ways that will scale properly, but many of the people who write formulas aren't thinking about large-size images when they write, they're just writing to try out an idea. So unless you know what to look for, it can be hit-or-miss. This is a general, recognized problem with UF, since there are now so many formulas in the database.
