Weird occurences with inputting textures into a GUI

[Pardeep]

Whenever I bind and add a texture that's 16x16 into a gui but that texture has no transparent areas (it's a black square), the texture renders fine into minecraft.

However when I do the exact same thing for a 16x16 texture that has transparent areaws (it's a circle) the texture won't load.

Here's the code that allows a texture to show when there's no transparent areas but not show when there is a transparent area:

GL11.glColor4f(1F, 1F, 1F, 1F);
Minecraft.getMinecraft().func_110434_K().func_110577_a(myLogo);
drawTexturedModalRect(2, 3, 0, 0, myLogoxSize, myLogoySize);

Is there any other code I need to put in for it to work?

enable blending

enable blending

I've tried using

GL11.glEnable(GL11.GL_BLEND);

and

GL11.glBlendFunc(GL11.GL_SRC_ALPHA, GL11.GL_ONE_MINUS_SRC_ALPHA);

I'm not sure if these are the wrong ones to use or if I'm structuring my code wrong.

Would you mind specifying which blend functions to use please?

Never mind, fixed it.

Apparently setting the texture file I had to 256x256 pixels fixed it
