Window / Re: Is sf::Window support dpi scaling on Windows?

« on: January 06, 2016, 03:07:32 am »

thanks for you reply, hapax

my code draw sprites and vectexarrays at the sf::renderwindow on another thread, so i need deactive the sf::window.

I didn't get any error message, the application is working fine except the win32 window and other controls are very small.

I ran some sfml examples on the tablet, like "opengl","win32",“window”, the window size is also not scaled,  it is real size.  Is that proved sf::window doesn't support dpi scaling? 

I am Wondering why the sf::window cause the win32 window losing dpi scaling effect.

Is this topic is talking about this? I am not good enough at english

Window / Is sf::Window support dpi scaling on Windows?

« on: January 05, 2016, 10:41:07 am »

hi, my application that using sfml is working fine until I need run it on a Windows 10 tablet with 10"(2048x1536) screen.


If  below codes is not called, the main window and child window is scaled to 200%, because the system setting is 200%, but when the sfml::Window is created from the child window's handle, the entire window (include main window and child window) are back to 100%, the controls and text is too small.

my application create a win32 main window and a child window, the child window's handle is m_hWnd.

// create sfml window
sf::ContextSettings settings;
settings.antialiasingLevel = 8;
m_sfWindow.create(m_hWnd, settings);
m_sfWindow.setActive(false);
 

I also tried create a independent window, the problem is still there

m_sfWindow.create(sf::VideoMode(800, 600), "My window");
m_sfWindow.setActive(false);

Graphics / Re: Draw video frames on sf::RenderWindow

Use multiple textures and multiple draw calls.

Thank you, Jesper. Problem solved by thor::BitSprite

I notice that on some computer that without display driver, the pieces of image didn't show at same time, Is it because of GDI rendering?

Graphics / [SOLVED]Draw video frames on sf::RenderWindow

« on: August 24, 2015, 10:26:48 am »

hi

I use sf::Texture + sf::Sprite to draw video frames on a sf::RenderWindow, it works fine on my computer.

but on some other computers, when create Texture, it fails, and output error:

Failed to create texture, its internal size is too high (2048x1024, maximum is 1024x1024)

Is there other way to draw images which is bigger than 1024x1024 on RenderWindow?
