Drawing a flat, specific part of a texture

[Ruki]

I'm currently porting over my existing game structure into Leadwerks engine and I'm having trouble on how to draw a flat 2D texture with specific UV coordinates. That is, rendering a specific part of a texture onto the screen. This is for my GUI elements.

 

I can only find DrawImage, which seems to work, but will only draw the entire texture, and not specifically a portion of the texture. Should I be using some other function? Thank you

DrawImage(texture, 50, 50, 200, 400);

 

Do I have to use some OpenGL commands? I've previously achieved this in DX9 by drawing a trianglestrip and passing in the UV coordinates

 

Sorry if this is a dumb question. Thank you

I'm not sure If i made myself clear, I want to be able to draw seperate GUI elements that are stored in one texture. I know how to convert the x/y pixel coordinates into UV floats, I just don't know which function I should be using in Leadwerks to render it. Thanks
