Hey all,
I need a control that can update/refresh an image on a web app rapidly - preferably on the order of 250 milliseconds or less.
There are problems with Xojo’s built-in controls:
1.) WebImageVIew - The update process for a new picture takes WAY, WAY, WAY to long. I’ve seen it take seconds and I need it a lot faster than that. And hitting it with an image change while it’s attempting to update itself basically starts the whole process over again and the image never updates.
2.) WebCanvas - I’m sure this would work better than a WebImageView for what I am trying to do but it caches every picture it gets. So if I am sending several pictures a second and a page is running this for any length of time, then it’s going to get ugly.
Before you all jump on me and start criticizing what I am doing and why I would want to take so much bandwidth, etc for a web page - relax. This web app runs primarily on a LAN for a very specific application. I really don’t care about bandwidth usage or any of the normal stuff you care about with a regular web page.
I am basically trying to capture some images off a device on my LAN as rapidly as possible and I want to display them in the browser as rapidly as possible. If I could use a WebCanvas w/o it caching, that would be great. But I think the limitations of the current controls is just a problem.
Does anyone have any ideas?
Jon
