This interface is implemented by classes which load images from a source. Normally, such a source will be an InputStream but can also be something else.
Field Summary | |
---|---|
static int |
MEDIUM_LOADING_PENALTY
Default/Medium conversion penalty (if there's some effort to load the image format) |
static int |
NO_LOADING_PENALTY
Used if the loading penalty is negligible (image doesn't need to be decoded). |
Method Summary | |
---|---|
ImageFlavor |
getTargetFlavor()
Returns the image flavor that is returned by this ImageLoader implementation. |
int |
getUsagePenalty()
Returns the penalty assigned to using this image loader. |
