Comment charger une image originale

Question

Bien que je dois charger une image d'origine, ont seulement un message d'erreur:

Bitmap trop volumineux pour être téléchargés dans une texture (5312x2988, max = 4096x4096)

Est-ce que quelqu'un sait comment résoudre ce problème?

Answer 1

Vous devez l'échelle à la taille maximale ou inférieure.

Vous pouvez obtenir la taille max avec ce code

int[] maxSize = new int[1]; gl.glGetIntegerv(GL10.GL_MAX_TEXTURE_SIZE, maxSize, 0);

Et bitmap à grande échelle avec

Bitmap.createScaledBitmap(Bitmap src, int dstWidth, int dstHeight, boolean filter) 

Answer 2

Vous pouvez jeter un oeil Picasso. Ceci est une bibliothèque très utile pour charger des images

Exemple:

Uri uri = Uri.fromFile(YOUR FILE)); 

Picasso.with(activity).load(uri) 
      .resize(96, 96).centerCrop().into(viewHolder.image);
