PImage.blend and display window
Feb 11th, 2009, 7:12pm  
Description in reference for PImage.blend said that:
"If the srcImg parameter is not used, the display window is used as the source image."

but

img.blend(x, y, width, height, dx, dy, dwidth, dheight, MODE)

seems to work like

img.blend(img, x, y, width, height, dx, dy, dwidth, dheight, MODE)

Does anyone knows: Is tis a bug or wrong description in reference or I miss something here?

Regards

The sentence comes right from the generic blend() page, I think it might need a rewording there...

Thanks PhiLho,

This probably means, that it is not possible to use PImage as destination and display window as source directly. And that sentence in documentation should be reworded as:

"If the srcImg parameter is not used, the destination image (img) is used as the source image. (to blend with itself)"

Do you think that, this is correct conclusion?

Bye,

You can specify g as source: img.blend(g, ...)

What the ...??

I tested and it works! You are full of tricks.

I was surprised, but then I saw that g is PGraphic variable associated with display window.

PhiLho, thanks for sharing this.
