Je débute avec la SDL, j'ai commencé par le tuto simple d'affichage d'image. If you don't want to worry about finding all these libraries, the SDL package I provide is good for most SDL beginners, as it provides SDL_image, and some other useful libraries. Many people would love to learn how to make a video game and it all starts with images. Note: Only a member of this blog may post a comment. You can set up SDL_image to load PNG files, which can save you a lot of disk space. Once you extract the contents of the zip file, you'll be able to find an You should now be able to build this program (Ctrl+Shift+B). Sample taken from the SDL_image documentation: SDL_Surface *IMG_Load(const char *file); More precisely, it loads ICO(Icon)/CUR(Cursor)/BMP, PNM (PPM/PGM/PBM), XPM, LBM(IFF ILBM), PCX, GIF, JPEG, PNG, TGA, TIFF, and XV thumbnail formats. Thanks to all authors for creating a page that has been read 4,058 times.wikiHow is where trusted research and expert knowledge come together. With that done, let's set up a new project using Visual Studio 2010. Last Updated 7/20/20 SDL extension libraries allow you do things like load image files besides BMP, render TTF fonts, and play music. It also has individual format functions such as IMG_isPNG and IMG_LoadPNG_RW. You'll need to initialise and cleanup the library (although it seems to work even without this) and remember to link the library and include the appropriate header file. Isn't that sweet? Create an Empty Project from the Visual C++ category. All we have left to do now is replace the line calling SDL_LoadBMP() with one that uses SDL 2 has a new dedicated function to blit images to a different size: SDL_BlitScaled. You'll need to initialise and cleanup the library (although it seems to work even without this) and remember to link the library and include the appropriate header file.

Have a look at the SDL_image library. To create this article, 15 people, some anonymous, worked to edit and improve it over time.

In the above codes, you can see that we are able to load BMP images only using SDL_LoadBMP() method. Like blitting images before, SDL_BlitScaled takes in a source surface to blit onto the destination surface. But as you can see, it's pretty straightforward. We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. It offers functions like IMG_LoadPNG that load your picture "as an" SDL_Surface. SDL_LoadBMP. First, we initialise SDL_image by calling  As you can also see we have a new image loading routine with loadTexture and a globally declared texture we're going to load. Contents. In order to display the image we will first use SDL_BlitSurface to blit the two surfaces and SDL_Flip to display the image. Your support helps wikiHow to create more in-depth illustrated articles and videos and to share our trusted brand of instructional content with millions of people all over the world. In the example here the image will stay on the screen until we press a key on the keyboard. Amid the current public health and economic crises, when the world is shifting dramatically and we are all learning and adapting to changes in daily life, people need wikiHow more than ever. Right click on the project and select They are very uncompressed and are heavy type of images which are not suitable for creating good games!

wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. Before you run it, though, make sure that SDL2.dll is in the same folder as your executable. To create this article, 15 people, some anonymous, worked to edit and improve it over time.

Let's concentrate on those development libraries for the moment. file: the file containing a BMP image: Return Value. Be sure to put the include files in the same directory as your SDL include files, and your lib files in the same directory as your SDL lib files to make things easier. An event loop is not necessary for displaying an image, but it allows us to keep the image on the screen until we want it to close.
