ImageMagick: MagickCore, C API for ImageMagick: Memory Allocation
Author: ImageMagick Studio LLC
Description: ImageMagick (TM) is a free software suite to create, edit and compose bitmap images. It can read, convert and write images in a large variety of formats. Images can be cropped, colors can be changed, various effects can be applied, images can be rotated and combined, and text, lines, polygons, ellipses and Bézier curves can be added to images and stretched and rotated. ImageMagick is free software: it is delivered with full source code and can be freely used, copied, modified and distributed. Its license is compatible with the GPL. It runs on all major operating systems. Most of the functionality of ImageMagick can be used interactively from the command line; more often, however, the features are used from programs written in the programming languages Perl, C, C++, Python, PHP, Ruby or Java, for which ready-made ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RubyMagick, and JMagick) are available. This makes it possible to modify or create images automa [cell cut: 1159 characters, first 1000 kept]

## AcquireMagickMemory AcquireMagickMemory() returns a pointer to a block of memory at least size bytes suitably aligned for any use. The format of the AcquireMagickMemory method is:
      void *AcquireMagickMemory(const size_t size)
A description of each parameter follows: #### size The size of the memory in bytes to allocate. ## CopyMagickMemory CopyMagickMemory() copies size bytes from memory area source to the destination. Copying between objects that overlap will take place correctly. It returns destination. The format of the CopyMagickMemory method is:
      void *CopyMagickMemory(void *destination,const void *source,
        const size_t size)
A description of each parameter follows: #### destination The destination. #### source The source. #### size The size of the memory in bytes to allocate. ## RelinquishMagickMemory RelinquishMagickMemory() zeros memory that has been allocated, frees it for reuse. The format of the RelinquishMagickMemory method is:
      void *RelinquishMagickMemory(void *memory)
A description of each parameter follows: #### memory A pointer to a block of memory to free for reuse. ## ResetMagickMemory ResetMagickMemory() fills the first size bytes of the memory area pointed to by memory with the constant byte c. The format of the ResetMagickMemory method is:
      void *ResetMagickMemory(void *memory,int byte,const size_t size)
A description of each parameter follows: #### memory A pointer to a memory allocation. #### byte Set the memory to this value. #### size Size of the memory to reset. ## ResizeMagickMemory ResizeMagickMemory() changes the size of the memory and returns a pointer to the (possibly moved) block. The contents will be unchanged up to the lesser of the new and old sizes. The format of the ResizeMagickMemory method is:
      void *ResizeMagickMemory(void *memory,const size_t size)
A description of each parameter follows: #### memory A pointer to a memory allocation. #### size The new size of the allocated memory. |
