Hello,
Sorry for delayed answer.
Is your question still actual?
You can use something like
// create RGBA8888 drawing buffer
ColorDrawBuffer buf = new ColorDrawBuffer(width, height);
// copy pixels into buf from your custom image
// .........
// put into DrawBufRef
DrawBufRef imageDrawBuf = buf;
// create image drawable
DrawableRef myCustomImageDrawable = new
ImageDrawable(imageDrawBuf);
// set drawable of ImageWidget
imageWidget.drawable = myCustomImageDrawable;
There was code in dlangui.graphics.image which could copy
FreeImage images to ColorDrawBuf, but in recent version it's
removed. You can check github revision history to get proper code.
BTW, why do you need FreeImage to create image? Isn't it just
possible inside dlangui?
