Interactive Image Manipulation

[Scott24x7]

I've come across a very odd one today.
I added an image for company logos to be displayed. But then I find some look weird in the block, as people do a lot of strange things with logos.

So I decided to add a radio button next to it that allows the user to change the visible image using the Stretch property.

In the click event of the radio button I put in:

DO CASE
	CASE This.Value = 1
		This.Parent.imgCompanyLogo.Stretch = 0
	CASE This.Value = 2
		This.Parent.imgCompanyLogo.Stretch = 1
	CASE This.Value = 3
		This.Parent.imgCompanyLogo.Stretch = 2
ENDCASE

Where the "weirdness" begins is, if I have a logo on the screen, and I push the first radio button ("Natural") then it sets the property to "0 - Clip" (default), but I have defaulted the image to 1 initially - Isometric.

What is odd is, if I start at the bottom, and click the lowest radio button first, the image appearance changes to Stretch (as it should). Then I click the 2nd radio button, and it changes to Isometric, as it should. Then I click the 1st radio button and it presents the image as "natural" (clipped if too big to fit in the object). So, that's all fine. BUT now if I click bottom radio button again, it's "sticks" on "Clipped". If I start the order of this sequence from first to last then once it gets set to "clipped" it never moves off it again...
Any idea what could be causing this?

Ah....
I figured this out.

What happens is, the size of the image at the time it is placed onto the form "is what it is".
If you then change the property from "Stretch" to "Clip", and the "Clip" image is larger than the Stretch, then all image relationships are to THOSE dimensions. So once you pick the "Clip", all further changes are in relation to THAT set of dimensions of the image, so any attempt to "stretch" it just yields the same image size. This is because the image takes on the dimension properties of the file selected. It does not keep them "fixed" to the size they were when you put the control on the form, unlike say a command button or a Shape...

So now I know the "why", but I've really no idea how to fix it... suggestions anyway?

LOL... so it seems I managed to answer my own question.

On the Radio button's click event the first thing I do is keep the image height and width constant by issuing:

This.Parent.imgControl.Height = <my height>
This.Parent.imgControl.Width = <my width>

So before the application of the change of "stretch" is made, the image size is always fixed in relation to the command, and not the actual size of the image in file.

I have discovered that "Isometric" is the best choice in most cases.

Please Scott - can't you loose the animated gif in your signature?
It's really annoying when trying to concentrate on your writings

 

[Mike Lewis]

I hate animated GIFs as well. In fact, I've disabled them at the browser level. I hadn't realised Scott's signature had them. But I'll second your suggestion, Dr D.

I've had this signature on Tek-Tips for over a decade, and you're the first to complain about it.

Actually, a quick check shows... it's been my signature for over 14 years on here.
I started using the site in July of 2001!

Interesting that you had no complaint in 14 years, and now two come along at once. That's the way it goes, I guess.

Actually, I wasn't complaining. Because I've always disabled animations, it's never been a problem for me. Maybe others do the same.

I never gave it any thought...
I like my guy pounding the other guy on the head with a hammer.
Giff has the typ-ie keyboard animated icon as well. I remember when Tek-Tips introduced them. I guess they were novel back then, I've never thought twice about them since.

Mike: How do you "disable them in the browser"? BTW - I'm using FF

 

[Scott24x7]

Funny but until you mentioned (Dr Dolittle) it I never realized I have for years been using that as a visual cue in my TT postings and responses, it makes it very easy to identify "mine" without having to read through a lot of stuff (i.e. I can see latest response since my last post in a thread). So sorry to disappoint but I'm going to leave them. They (for me) are actually very useful speed element.

To disable animations in Firefox, first navigate to about:config. The search for animat. This will show all the config entries with that string in the name. One of these is image.animation_mode. Double-click it and set its value to none.

This stops several types of animations, not just GIFs. Browse around settings with similar names to see what else you can change.

(Actually, the best thing you can do is to install FlashBlock. This kills all those horrendous Flash animations and videos cold dead - except any that you choose to override.)

FWIW, I've always found the animated signature annoying, but not enough to comment on it until someone else did.

But I also find religious messages in signatures annoying and I don't comment on those either.

Thanks Mike!

But I also find religious messages in signatures annoying and I don't comment on those either.

Blatant "political" too, and I normally wouldn't comment either.

 

[Scott24x7]

Funny, I never comment on signatures. I'm kind of baffled how I started this trend.
