GUICtrlSetImage returning success on failure

[sshrum]

I'm trying to pass an image to the GUICtrlSetImage and the function is returning success on a image (JPG) that it's not displaying (the gui window is empty).

The image can be found here:

http://www.deviantart.com/deviation/34318122/

Click on the image to get the fullsize and do a right-click 'Save as...'.

How do I test to see if the image actually is displayed?

By making sure that the file is bmp, not jpg or anything else?

File is a jpg...which the picture control supports (I'm loading a ton of other jpg files that work)

Not sure if it's a jpg2k file thou.

There's a good question...does the pic control support jpg2k files?

Picture control (GUICtrlCreatePic) supports, GUICtrlSetImage doesn't.

Huh?

Then how do you change a image in a already created picture control? CreatePic creates a new object...SetImage allows for defining a image in an existing pic control.

The help file isn't specific enough...you can use jpg's and gifs as well in relation to the pic control.

Per the help file in regards to CreatePic:

To set or change information in the control see GUICtrlSet....

To update the picture after the dialog box is displayed just use GUICtrlSetImage

Ok, my bad.

So what you're saying is, that you have a GUICtrlCreatePic with some image, then later try to change it with GUICtrlSetImage with that image from the link you posted, and it doesn't work? Can you post an example which reproduces such behaviour? Works for me...

I think the answer to the question I'm about to pose may explain your problems as well...

Is there an undocumented limit on the resolution of pictures (.jpg in this case) that can be displayed in a Picture Control (GUICtrlCreatePic)?

It seems to me that there is - I find that no picture wider than 2730 pixels will display, no matter the height -

2730x2048 (approx. .75 ratio - normal ratio for digital pictures) works.

2731x2048 doesn't work

2730x8000 works (but it's slow, as that's a big file)

2731x1 doesn't work

1x10000 works

So it appears that the height doesn't matter, but the width cannot go over 2730.

Has anyone else found this?

Is this a known limitation (it's not listed in the 'technical limits of AutoIt' section of the helpfile)?

Is there a way around it?

Should this be listed in the bugs section?

I know that seems like a large picture to be displaying, but our camera (just a basic point-and-shoot) takes pictures over that resolution without breaking a sweat, and when I'm trying to write a program to allow me to use them to prompt the user, I kind of need to be able to display them.

I note also that the picture sshrum is trying to display is wider than this limitation, so my guess is that's why your picture isn't showing up.

Thanks!

Edit: Wow...200 posts to my name and I'm still asking for help!

Edit2: I just noticed that pictures that don't work on our main computer (running Vista) DO display on my laptop (XP), so maybe that's the problem. sshrum...are you running Vista too?
