Inconsistency in sf::Image::copy

[emlai]

sf::Image::copy allows the images to overlap like this (red is the target image, green is the source image):



but not like this:



I think this behavior is inconsistent. Is there a rationale for this or is this just an oversight?

Overlap where, when, what? Are you talking about source/destination rectangles here with your images? What is the red rectangle, what is the green rectangle?

[emlai]

What is the red rectangle, what is the green rectangle?

Please read the post.

The right/bottom tests are implemented here. Seems like left/top would just need a similar test to make your second example work.

In addition to that the destX and destY parameters would need to be int, rather than unsigned int.

since x_y coords in c++ goes like this:
--->
|
v

your first image shows the green image being added at a positive X and y coordinate on the red image
but the second shows it being added at a negative coordinate. said coordinate could be out of bounds for the image. (eg, you are trying to draw outside of the paper)

just my thoughts....
