Window / Re: Own window design from .png with shadows

Works perfect! Thank you very much. But can you explain about BLENDFUNCTION, DC, BITMAPS, etc. or give a good article about it all? And why UpdateLayeredWindow need to call not in cycle?

As I already said...

I'm not sure, but are you trying to create a partially transparent window? That is unfortunately not supported directly through SFML.

Ok, it's called partially transparent window. If SFML don't support it, can I do create this through winapi's "Layered Windows"? Somebody know good articles?

Yes, I did. With window filled by color shadows is like on image. But I don't need to have background color. :-(

Window.clear(sf::Color::Transparent);

I think this color is the problem. If you changes it to White or Black the sprite's transparency will probably work.

No, it's only fill the window by specific color.

/path/to/image - whatever .png image with outer shadows and without background color. I posted an example up in this thread.

Viewer Program shows image with shadows. All is fine. I also tried saving .png as "Export for Web -> PNG 24 bit"(photoshop) menu option, but it too didn't work.

Window / Own window design from .png with shadows

« on: March 04, 2016, 07:13:28 pm »

Hello guys.

1) I have a .psd design and some layers of it uses blending mode with shadows.
2) I create a .png of background image which takes layers with shadow.
3) I create a window that has "sf::Style::None" style.

And as result I taking the window where shadows of background image replaced by black pixels.

What i do in my code:
1) Create window with "sf::Style::None".
2) Load background-image to sf::Image, load image to sf::Texture, and create sf::Sprite from this texture.

Also it all looks like very bold border around image.

Thanks for answers.

Graphics / Re: White rectangle

Have you searched before posting? This problem has appeared dozens of times in the past. It always has to do with textures that are invalidated.

There are several mistakes in your code: You don't check for errors when loading, you return a copy (instead of reference) in GetTexture(), and you needlessly allocate a dynamic texture, where you could directly load the texture inside the map. The destructor is also unnecessary, STL containers clean up properly on their own.

Thank you very much. I used the search before, I understood the problem, but I did not understand the decision. I did not consider the option of using references. Thank you again!
