Set Image URL?

[[CLRP]extra]

Anyone know how to set a panels texture/material to a URL image? I've seen it before but lost as to how people do it.

I created a library for getting a material from a URL: [URL="https://github.com/pixeltailgames/gm-mediaplayer/blob/master/lua/autorun/includes/modules/htmlmaterial.lua"]htmlmaterial.lua[/URL] which depends on [URL="https://github.com/pixeltailgames/gm-mediaplayer/blob/master/lua/autorun/includes/modules/browserpool.lua"]browserpool.lua[/URL] and [URL="https://github.com/pixeltailgames/gm-mediaplayer/blob/master/lua/mediaplayer/controls/dmediaplayerhtml.lua"]an extended DHTML derma control[/URL].

Usage:

[lua]local mat = HTMLMaterial( "https://example.com/example.png" )[/lua]

Thanks but is there no simpler way to do it? I mean just a default Gmod function or something preferably less lines of code.

The only way I'm aware of doing it is by creating an Awesomium context and grabbing the painted texture.

I tried your html material module and for some reason it spams the console with errors:
"attempt to call gloabal 'HTMLMaterial' (a nil value)"

[samm5506]

I added an extra dependency to the original post, make sure you have each of them included.

Hmm, everything you mentioned added and I still get the error. This the right usage?

HTMLTest.Paint = function()
local ourMat = HTMLMaterial("https://celadorsanitario.files.wordpress.com/2011/11/aptitude_test1.gif")
	surface.SetDrawColor( 255, 255, 255, 255 )
	surface.SetMaterial( ourMat ) -- If you use Material, cache it!
	surface.DrawTexturedRect( 0, 0, HTMLTest:GetWide(), HTMLTest:GetTall() )
end

Yes, it sounds like you didn't set the files to be downloaded on the client though.

[lua]-- Must include these somewhere
if SERVER then
AddCSLuaFile("dmediaplayerhtml.lua")
AddCSLuaFile("browserpool.lua")
AddCSLuaFile("htmlmaterial.lua")
else
include("dmediaplayerhtml.lua")
include("browserpool.lua")
include("htmlmaterial.lua")
end

-- btw, PANEL.Paint passes in width and height
HTML.Paint = function(self, width, height)
-- ...
end[/lua]

Made a module that included them, still get errors. Im guessing im just being plain stupid here but please correct me if i've done it wrong.

It also posts an error saying: attempt to index global 'derma' (a nil value)

derma.DefineControl( "DMediaPlayerHTML", "", PANEL, "Awesomium" )

[samm5506]

Are you sure you're not including it on the server? It should always exist on the client. Post your module's code.

A file in modules thats simply:

if SERVER then
    AddCSLuaFile("dmediaplayerhtml.lua")
    AddCSLuaFile("browserpool.lua")
    AddCSLuaFile("htmlmaterial.lua")
else
    include("dmediaplayerhtml.lua")
    include("browserpool.lua")
    include("htmlmaterial.lua")
end

Maybe the files are getting included before Garry's Mod has finishing loading all of it's dependencies (derma lib)? You might want to try placing your files in an addon.

It works fine with the gm media player addon in the addons folder. I'll just do it that way, thanks :)
