How to display an image in the console using C language…
In C language, it is not possible to directly output images to the console. The console only supports text output and cannot display images. If you want to display images in C language, you can use graphics libraries like OpenGL or SDL. These libraries provide functions for drawing graphics and can display images in a window. Here is an example of using the SDL library to display an image in a window:
#include <stdio.h>
#include <SDL.h>
int main(int argc, char *argv[]) {
SDL_Window *window = NULL;
SDL_Renderer *renderer = NULL;
SDL_Texture *texture = NULL;
SDL_Surface *imageSurface = NULL;
// Initialize SDL
if (SDL_Init(SDL_INIT_VIDEO) < 0) {
printf("SDL could not initialize! SDL_Error: %s\n", SDL_GetError());
} else {
// Create window
window = SDL_CreateWindow("Image Viewer", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 640, 480, SDL_WINDOW_SHOWN);
if (window == NULL) {
printf("Window could not be created! SDL_Error: %s\n", SDL_GetError());
} else {
// Create renderer
renderer = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED);
if (renderer == NULL) {
printf("Renderer could not be created! SDL_Error: %s\n", SDL_GetError());
} else {
// Load image
imageSurface = SDL_LoadBMP("image.bmp");
if (imageSurface == NULL) {
printf("Image could not be loaded! SDL_Error: %s\n", SDL_GetError());
} else {
// Create texture
texture = SDL_CreateTextureFromSurface(renderer, imageSurface);
if (texture == NULL) {
printf("Texture could not be created! SDL_Error: %s\n", SDL_GetError());
} else {
// Clear renderer
SDL_RenderClear(renderer);
// Draw texture
SDL_RenderCopy(renderer, texture, NULL, NULL);
// Update renderer
SDL_RenderPresent(renderer);
// Wait for window close event
SDL_Event event;
int quit = 0;
while (!quit) {
while (SDL_PollEvent(&event) != 0) {
if (event.type == SDL_QUIT) {
quit = 1;
}
}
}
}
}
}
}
}
// Free resources
SDL_DestroyTexture(texture);
SDL_FreeSurface(imageSurface);
SDL_DestroyRenderer(renderer);
SDL_DestroyWindow(window);
SDL_Quit();
return 0;
}
In the above example, we need to name the image to be displayed as “image.bmp” and place it in the same directory as the C source file. Then, use the SDL library to load the image and create a window, renderer, and texture, and finally draw the texture in the window. The program will continue to run until the window is closed.
