DImage
Description
DImage is an advanced, more robust version of the Material panel.
See DImageButton for a click-able version of this panel.
Parent
Derives from DPanel.
Methods
DImage:DoLoadMaterial()
This is used internally - although you're able to use it you probably shouldn't.
Actually loads the IMaterial to render it. Called from DImage:LoadMaterial.
DImage:FixVertexLitMaterial()
This is used internally - although you're able to use it you probably shouldn't.
"Fixes" the current material of the DImage if it has VertexLit shader by creating a new one with the same name and a prefix of "_DImage" and automatically calling DImage:SetMaterial with the new material.
This fixes the problem where using materials using shaders that expect lighting information causing "weird" flickering when displayed in 2D/Unlit environment.
string DImage:GetFailsafeMatName()
This is used internally - although you're able to use it you probably shouldn't.
Returns the texture path set by DImage:SetFailsafeMatName.
boolean DImage:GetKeepAspect()
Returns whether the DImage should keep the aspect ratio of its image when being resized.
See DImage:SetKeepAspect for more info on how it works.
string DImage:GetMatName()
This is used internally - although you're able to use it you probably shouldn't.
Returns the texture path set by DImage:SetMatName.
DImage:LoadMaterial()
This is used internally - although you're able to use it you probably shouldn't.
Initializes the loading process of the material to render if it is not loaded yet.
You do not need to call this function. It is done for you automatically.
DImage:PaintAt( number posX, number posY, number width, number height )
Paints a ghost copy of the DImage panel at the given position and dimensions. This function overrides Panel:PaintAt.
DImage:SetFailsafeMatName( string backupMat )
This is used internally - although you're able to use it you probably shouldn't.
Sets the backup material to be loaded when the image is first rendered. Used by DImage:SetOnViewMaterial.
DImage:SetImage( string strImage, string strBackup = "nil" )
Sets the image to load into the frame. If the first image can't be loaded and strBackup is set, that image will be loaded instead.
This eventually calls DImage:SetMaterial.
DImage:SetKeepAspect( boolean keep )
Sets whether the DImage should keep the aspect ratio of its image when being resized.
Note that this will not try to fit the image inside the button, but instead it will fill the button with the image.
DImage:SetMatName( string mat )
This is used internally - although you're able to use it you probably shouldn't.
Sets the material to be loaded when the image is first rendered. Used by DImage:SetOnViewMaterial.
DImage:SetOnViewMaterial( string mat, string backupMat )
Similar to DImage:SetImage, but will only do the expensive part of actually loading the textures/material if the material is about to be rendered/viewed.
Useful for cases like DIconBrowser, where there are hundreds of small icons in 1 panel in a list that do not need all to be loaded at the same time.
Example
Creates a DImage of Dr. Breen inside a DFrame panel.
-- Frame
Frame = vgui.Create("DFrame")
Frame:SetSize(200, 200)
Frame:Center()
Frame:SetTitle("Image of Dr. Breen") -- Title of window
-- Image panel of Dr. Breen
local breen_img = vgui.Create("DImage", Frame) -- Add image to Frame
breen_img:SetPos(10, 35) -- Move it into frame
breen_img:SetSize(150, 150) -- Size it to 150x150
-- Set material relative to "garrysmod/materials/"
breen_img:SetImage("scripted/breen_fakemonitor_1")
Example
Creates three DImage panels and arranges them into a new image.
-- Container panel
BGPanel = vgui.Create("DPanel")
BGPanel:SetSize(400, 400)
BGPanel:Center()
BGPanel:SetDrawBackground(false)
-- Wood background
local img_bg = vgui.Create("DImage", BGPanel)
img_bg:SetSize(BGPanel:GetSize())
img_bg:SetImage("models/props_foliage/oak_tree01")
-- Blurred out screenshot of Construct
local img_construct = vgui.Create("DImage", BGPanel)
img_construct:SetPos(10, 10)
img_construct:SetSize(380, 380)
img_construct:SetImage("hlmv/background")
-- Flatgrass sign
local img_text = vgui.Create("DImage", BGPanel)
img_text:SetPos(10, 20)
img_text:SetSize(380, 130)
img_text:SetImage("gm_construct/flatsign")
