# Module deprecate Methods

## AcquireCacheViewIndexes

AcquireCacheViewIndexes() returns the indexes associated with the specified view.

Deprecated, replace with:

          GetCacheViewVirtualIndexQueue(cache_view);

The format of the AcquireCacheViewIndexes method is:

      const IndexPacket *AcquireCacheViewIndexes(const CacheView *cache_view)

A description of each parameter follows:

##### cache_view

the cache view.

## AcquireCacheViewPixels

AcquireCacheViewPixels() gets pixels from the in-memory or disk pixel cache as defined by the geometry parameters. A pointer to the pixels is returned if the pixels are transferred, otherwise a NULL is returned.

Deprecated, replace with:

          GetCacheViewVirtualPixels(cache_view,x,y,columns,rows,exception);

The format of the AcquireCacheViewPixels method is:

      const PixelPacket *AcquireCacheViewPixels(const CacheView *cache_view,
        const ssize_t x,const ssize_t y,const size_t columns,
        const size_t rows,ExceptionInfo *exception)

A description of each parameter follows:

##### cache_view

the cache view.

##### x,y,columns,rows

These values define the perimeter of a region of pixels.

##### exception

return any errors or warnings in this structure.

## AcquireImagePixels

AcquireImagePixels() returns an immutable pixel region. If the region is successfully accessed, a pointer to it is returned, otherwise NULL is returned. The returned pointer may point to a temporary working copy of the pixels or it may point to the original pixels in memory. Performance is maximized if the selected region is part of one row, or one or more full rows, since there is opportunity to access the pixels in-place (without a copy) if the image is in RAM, or in a memory-mapped file. The returned pointer should *never* be deallocated by the user.

Pixels accessed via the returned pointer represent a simple array of type PixelPacket. If the image type is CMYK or the storage class is PseudoClass, call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to access the black color component or to obtain the colormap indexes (of type IndexPacket) corresponding to the region.

If you plan to modify the pixels, use GetAuthenticPixels() instead.

Note, the AcquireImagePixels() and GetAuthenticPixels() methods are not thread-safe. In a threaded environment, use GetCacheViewVirtualPixels() or GetCacheViewAuthenticPixels() instead.

the image list.

## GetImagePixels

GetImagePixels() obtains a pixel region for read/write access. If the region is successfully accessed, a pointer to a PixelPacket array representing the region is returned, otherwise NULL is returned.

The returned pointer may point to a temporary working copy of the pixels or it may point to the original pixels in memory. Performance is maximized if the selected region is part of one row, or one or more full rows, since then there is opportunity to access the pixels in-place (without a copy) if the image is in RAM, or in a memory-mapped file. The returned pointer should *never* be deallocated by the user.

Pixels accessed via the returned pointer represent a simple array of type PixelPacket. If the image type is CMYK or if the storage class is PseduoClass, call GetAuthenticIndexQueue() after invoking GetImagePixels() to obtain the black color component or colormap indexes (of type IndexPacket) corresponding to the region. Once the PixelPacket (and/or IndexPacket) array has been updated, the changes must be saved back to the underlying image using SyncAuthenticPixels() or they may be lost.

## SetImagePixels

SetImagePixels() queues a mutable pixel region. If the region is successfully initialized a pointer to a PixelPacket array representing the region is returned, otherwise NULL is returned. The returned pointer may point to a temporary working buffer for the pixels or it may point to the final location of the pixels in memory.

Write-only access means that any existing pixel values corresponding to the region are ignored. This useful while the initial image is being created from scratch, or if the existing pixel values are to be completely replaced without need to refer to their pre-existing values. The application is free to read and write the pixel buffer returned by SetImagePixels() any way it pleases. SetImagePixels() does not initialize the pixel array values. Initializing pixel array values is the application's responsibility.

Performance is maximized if the selected region is part of one row, or one or more full rows, since then there is opportunity to access the pixels in-place (without a copy) if the image is in RAM, or in a memory-mapped file. The returned pointer should *never* be deallocated by the user.

Pixels accessed via the returned pointer represent a simple array of type PixelPacket. If the image type is CMYK or the storage class is PseudoClass, call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to obtain the black color component or the colormap indexes (of type IndexPacket) corresponding to the region. Once the PixelPacket (and/or IndexPacket) array has been updated, the changes must be saved back to the underlying image using SyncAuthenticPixels() or they may be lost.

          QueueAuthenticPixels(image,x,y,columns,rows,&image->exception);

The format of the SetImagePixels() method is:
