Submitting that command buffer will result in an image with a complete mip-chain and all mip levels being transitioned to the proper image layout for shader reads.

### Image View creation
The Image View also requires information about how many Mip Levels are used. This is specified in the ```VkImageViewCreateInfo.subresourceRange.levelCount``` field.
```cpp
VkImageViewCreateInfo view = vks::initializers::imageViewCreateInfo();
view.image = texture.image;
view.viewType = VK_IMAGE_VIEW_TYPE_2D;
view.format = format;
view.components = { VK_COMPONENT_SWIZZLE_R, VK_COMPONENT_SWIZZLE_G, VK_COMPONENT_SWIZZLE_B, VK_COMPONENT_SWIZZLE_A };
view.subresourceRange.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT;
view.subresourceRange.baseMipLevel = 0;
view.subresourceRange.baseArrayLayer = 0;
view.subresourceRange.layerCount = 1;
view.subresourceRange.levelCount = texture.mipLevels;
```
