Image Rendering

12-08-2009, 07:40 AM

Hey.

I haven't done that much with images for know.
I tried to use a simple ReplaceableTextures\CommandButtons\BTN$anything$.blp image from blizzard and to display it in 64px size.

I know that I have to use SetImageRenderAlways, but then the image is ugly, while 1/4 of it is only the image itself and 3/4 of it ugly rendering borders.

Image Creation Code:

JASS:

        public static method create takes player p, string s, real size, real posX, real posY, real posZ, integer imageType returns thistype
            local thistype this = thistype.allocate()
            local string path = ""
        
            if GetLocalPlayer() == p then
                set path = s
            else
                set path = ""
            endif
            
            set .Handle = CreateImage(path, size, size, size, posX, posY, posZ, 0, 0, 0, imageType)
            set .PosX = posX
            set .PosY = posY
            set .PosZ = posZ
            set .Type = imageType
            set .Owner = p
            set .Path = s
            
            call SetImageRenderAlways(.Handle, true)
            
            return this
        endmethod

// Another struct

        public method createImage takes player p, string s, real size, real posX, real posY, real posZ, integer imageType returns Image
            local Image i = Image.create(p, s, size, posX, posY, posZ, imageType)
            
            //: Save the image
            set .ImageTable[GetHandleId(i.getHandle())] = integer(i)
            
            return i
        endmethod

// Just Another struct that extends Another struct
        public method initImages takes nothing returns nothing
            local integer i = 0
            
            loop
                exitwhen i >= 15
                set SwitchImages[i] = .createImage(Player(i), "ReplaceableTextures\\Splats\\AuraRune9b.blp", 64., 128., 0., 0., 3)  
                set SwitchStates[i] = true
                
                set i = i + 1
            endloop
        endmethod

Viikuna-

Ive had this problem too, and I think it was caused by having not fully alphaed borders in that image file.

edit.

Also, you should probably do it like this, in case you wanna change that images visibility for some players or something.

JASS:

           local thistype this = thistype.allocate()
            
            set .Handle = CreateImage(s, size, size, size, posX, posY, posZ, 0, 0, 0, imageType)
            set .PosX = posX
            set .PosY = posY
            set .PosZ = posZ
            set .Type = imageType
            set .Owner = p
            set .Path = s
            
            call SetImageRenderAlways(.Handle, true)
            call ShowImage(.Handle,GetLocalPlayer() == p)
            
            return this

Anachron	So blizzards default images do not have an alpha channel? Btw thanks for the hint, it would be a bad bug. On testmap: If you click on the trackable you hide / display the image.
