  • SDL save screenshot on iOS

    12 avril 2018, par Law Gimenez

    I am trying to save a screen or frame from the SDL’s "window" into a PNG file and so I’m using SDL_image library. My code is below

    IMG_Init(Int32(IMG_INIT_PNG.rawValue))
    
let screenShot = SDL_CreateRGBSurface(0, 640, 480, 32, 0, 0, 0, 0)
    
SDL_SetRenderTarget(renderer, texture)
    
SDL_RenderReadPixels(renderer, nil, Uint32(SDL_PIXELFORMAT_ARGB8888), screenShot?.pointee.pixels, (screenShot?.pointee.pitch)!)
    
let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String
    
IMG_SavePNG(screenShot, "\(documentsPath)/image.png")
    
SDL_FreeSurface(screenShot)

    But the image.png was not saved. If anyone can lead or help me. Thank you !

    Additional code, the image saved is just black

    IMG_Init(Int32(IMG_INIT_PNG.rawValue))
    
let screenShot = SDL_CreateRGBSurface(Uint32(SDL_SWSURFACE), 640, 480, 32, 0, 0, 0, 0)
    
// SDL_SetRenderTarget(renderer, texture)
    
SDL_RenderReadPixels(renderer, nil, Uint32(SDL_PIXELFORMAT_ARGB8888), screenShot?.pointee.pixels, (screenShot?.pointee.pitch)!)
    
// Save to documents directory
    
let fileManager = FileManager.default
    
do {
    
    let documentDirectory = try fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
    
    let fileUrl = documentDirectory.appendingPathComponent("imageLOL.png")
    
    if !fileManager.fileExists(atPath: fileUrl.path) {
    
        print("File NO exists")
    
        // Create file at path
    
        let data = Data()
    
        let createFile = fileManager.createFile(atPath: fileUrl.path, contents: data, attributes: nil)
    
        if createFile {
    
            print("Create file success")
    
        } else {
    
            print("Create file failed")
    
        }
    
    } else {
    
        print("File exists")
    

    
    }
    
    let result = IMG_SavePNG(screenShot, fileUrl.path)
    
    print("result = \(result)")
    
    // After saving screenshot
    
    let image = UIImage(contentsOfFile: fileUrl.path)
    
    let imageData = UIImagePNGRepresentation(image!)
    
    print("image length = \(String(describing: imageData?.count))")
    
    UIImageWriteToSavedPhotosAlbum(image!, nil, nil, nil)
    
    SDL_FreeSurface(screenShot)
    
} catch {
    
    print("Error docs = \(error)")
    
}

    swscale/graph : add color mapping pass

    This leverages the previously introduced color management subsystem in order
    
to adapt between transfer functions and color spaces, as well as for HDR tone
    
mapping.
    

    Take special care to handle grayscale formats without a colorspace
    
gracefully.
