ApiQueryImageInfo::checkParameterNormalise (   $image,
  $finalParams 
)
protected

Verify that the final image parameters can be normalised.

This doesn't use the normalised parameters, since $file->transform expects the pre-normalised parameters, but doing the normalisation allows us to catch certain error conditions early (such as missing required parameter).

Parameters
File$image
array$finalParamsList of parameters to transform image with

static ApiQueryImageInfo::getTransformCount ( )

Get the count of image transformations performed.

ApiQueryImageInfo::mergeThumbParams (   $image,
  $thumbParams,
  $otherParams 
)
protected

Validate and merge scale parameters with handler thumb parameters, give error if invalid.

We do this later than getScale, since we need the image to know which handler, since handlers can make their own parameters.

Parameters
File$imageImage that params are for.
array$thumbParamsThumbnail parameters from getScale
string$otherParamsString of otherParams (iiurlparam).
Returns
array Array of parameters for transform.
