Detailed Description

Struct: gdScaleOptions

Options for gdImageScaleWithOptions.

Members: fit - Aspect-ratio behavior. See gdScaleFit. gravity - Crop or padding anchor. See gdScaleGravity. strategy - Optional cover-crop strategy. See gdScaleStrategy. background_color - Truecolor ARGB background used for padding and for transparent palette pixels. interpolation - A gdInterpolationMethod value (see gdImageSetInterpolationMethod), or GD_SCALE_INTERPOLATION_AUTO.

Defaults: If the options pointer passed to gdImageScaleWithOptions is NULL, gd uses GD_SCALE_FIT_COVER, GD_SCALE_GRAVITY_CENTER, GD_SCALE_STRATEGY_NONE, background color 0x7f000000 and GD_SCALE_INTERPOLATION_AUTO.

Notes: For palette sources, gd prepares a truecolor working copy. Transparent pixels are replaced with background_color before scaling; if background_color is a valid palette index, that palette entry is converted to truecolor.
