Detailed Description

The ActionComponents.ACImage is a static class that adds several helpful utilities for dealing with images as Bitmaps.

The ActionComponents.ACImage attempts to maintain the same calling structure and functionality with the iOS version of the ActionPack to assist in building cross platform mobile applications. Available in ActionPack Business or Enterprise only.

static int ActionComponents.ACImage.CalculateInSampleSize	(	BitmapFactory.Options	options,
		int	reqWidth,
		int	reqHeight
	)

static

Calculates the sampling factor for an image being loaded into memory and down-sampled at the same time

Returns: The in sample size.

Parameters

options	Options.
reqWidth	Req width.
reqHeight	Req height.

Here is the caller graph for this function:

static int ActionComponents.ACImage.CalculateInSampleSize	(	ACImageInfo	info,
		int	reqWidth,
		int	reqHeight
	)

static

Calculates the sampling factor for an image being loaded into memory and down-sampled at the same time

Returns: The in sample size.

Parameters

info	Info.
reqWidth	Req width.
reqHeight	Req height.

static Bitmap ActionComponents.ACImage.FromFile ( string filename )

static

Loads the image from the given filename and path

Returns: The image as a Bitmap or null on error

Parameters

filename The full path and filename of the image to load

The resulting bitmap will allocate its pixels such that they can be purged if the system needs to reclaim memory.

Here is the caller graph for this function:

static Bitmap ActionComponents.ACImage.FromFile	(	string	filename,
		int	width,
		int	height
	)

static

Loads the image from the given filename and path resampling it to the requested height/width

Returns: The image as a Bitmap or null on error

Parameters

filename	The full path and filename of the image to load
width	Width.
height	Height.

The resulting bitmap will allocate its pixels such that they can be purged if the system needs to reclaim memory.

Here is the call graph for this function:

static Bitmap ActionComponents.ACImage.FromFile	(	string	filename,
		BitmapFactory.Options	options
	)

static

Loads the image from the given filename and path with the given options

Returns: The image as a Bitmap or null on error

Parameters

filename	The full path and filename of the image to load
options	Options.

static Bitmap ActionComponents.ACImage.FromResource	(	Android.Content.Res.Resources	resources,
		int	resourceID
	)

static

Loads the image from the given resources and resource ID

Returns: The image as a Bitmap or null on error

Parameters

resources	Resources.
resourceID	Resource ID.

The resulting bitmap will allocate its pixels such that they can be purged if the system needs to reclaim memory.

Here is the caller graph for this function:

static Bitmap ActionComponents.ACImage.FromResource	(	Android.Content.Res.Resources	resources,
		int	resourceID,
		int	width,
		int	height
	)

static

Loads the image from the given resources and resource ID resampling it to the requested height/width

Returns: The image as a Bitmap or null on error

Parameters

resources	Resources.
resourceID	Resource ID.
width	Width.
height	Height.

The resulting bitmap will allocate its pixels such that they can be purged if the system needs to reclaim memory.

		int	resourceID,
		BitmapFactory.Options	options
	)

static

Loads the image from the given resources and resource ID with the given options

Returns: The image as a Bitmap or null on error

Parameters

resources	Resources.
resourceID	Resource ID.
options	Options.

static ACImageInfo ActionComponents.ACImage.ImageInfoFromFile ( string filename )

static

Queries the given image file and returns information about the file in a ActionComponents.ACImageInfo

Returns: The info from file.

Parameters

filename Filename.

This method queries the image file without actually loading it into memory

Here is the caller graph for this function:

static ACImageInfo ActionComponents.ACImage.ImageInfoFromResource	(	Android.Content.Res.Resources	resources,
		int	resourceID
	)

static

Queries the image resource and returns information about it in a ActionComponents.ACImageInfo

Returns: The info from resource.

Parameters

resources	Resources.
resourceID	Resource ID.

This method queries the image resource without actually loading it into memory

Here is the caller graph for this function:

static Bitmap ActionComponents.ACImage.RotateImage	(	Bitmap	bitmap,
		int	degrees
	)

static

Rotates the given image Bitmap about it center axis to the given degrees

Returns: The image.

Parameters

bitmap	Bitmap.
degrees	Degrees.

Negative degrees rotate counter-clockwise
