[JASS] Show Image

[Kanadaj]

Hey guys
I've been trying to show images via jass as you can't do it via GUI, but the thing is I managed to show an icon, but it's edge pixels got stretched to 2x more it's width/height... Any idea how to solve it?

function CreateImageEx takes string imagePath, real size, real x, real y, real z, boolean showImage returns image
    local image i = CreateImage(imagePath, size, size, 0, x - (size / 2), y - (size / 2), z, 0, 0, 0, 2)
    call SetImageRenderAlways(i, true)
    call ShowImage(i, showImage)
    return i
endfunction

function CreateImageExLoc takes string imagePath, real size, location whichLocation, real z, boolean showImage returns image
    return CreateImageEx(imagePath, size, GetLocationX(whichLocation), GetLocationY(whichLocation), z, showImage)
endfunction

• Custom script: set udg_TempImage = CreateImageExLoc("Replaceable Textures\\Command Buttons\\BTNAvatar.blp",64,udg_TempPoint,0,true)

There is no fix except to import an edited version of the icon.

You can read this tutorial for some information on images:

To fix the problem, you have to make a 1 pixel border of transparency around the icon.

CreateImageEx leaks a handle ID each time you call it.

Yeah, I was just pointing him into the direction of actually creating the image so it wouldn't stretch.

If you want a non-leaking script, you can use something like this:

globals
    image CreateImageEx_i
endglobals

function CreateImageEx takes string imagePath, real size, real x, real y, real z, boolean showImage returns image
    set CreateImageEx_i = CreateImage(imagePath, size, size, 0, x - (size / 2), y - (size / 2), z, 0, 0, 0, 2)
    call SetImageRenderAlways(CreateImageEx_i, true)
    call ShowImage(CreateImageEx_i, showImage)
    return CreateImageEx_i
endfunction
