Correct usage of Image class

[StOneDOes]

Hi guys,

Trying to get your take on the correct usage of the Image class. I'm trying to change the image of a widget using SetImage(). It seems that the documentation is incomplete, missing the Image class (unless I've missed it :S). Through trying to use this class, I've noticed that Image::Load() has been commented out in Window.win32.h (perhaps it was not finished?).

I instead tried something like:

wstring str = L"Materials/GUI/button1.tex";

Image *image = new Image();
image->Initialize( str );

Which exited my program after attempting a run, not sure why.

This is not yet officially supported, but you want to use the GUI image commands.  A GUI may be created on a window (which you guys don't need, but I do to make the Leadwerks 5 editor) or on a context.  Depending on which is used, the image class will either use textures or OS commands to produce the same results.

Okay thank you for the heads up.  Also your suggestion works fine:

Image *image = gui->LoadImageA( "Materials/GUI/button1.tex" );
widget->SetImage( image );
widget->Redraw();

The only issue I've run into now is that Leadwerks is automatically resizing my button image into multiples of 64. I also can't find a way to rescale the image. Is there a way around this?

In the editor, disable the mipmaps generation on that texture.

Thanks for this! Did that and then changed the compression to uncompressed and it works
