+ Now that ImageMagick version 7 is released, we continue
+ to maintain the legacy release of ImageMagick, version 6, at
+ https://legacy.imagemagick.org. Learn how ImageMagick version 7 differs
+ from previous versions with our porting guide.
+
+ ImageMagick best practices strongly encourages you to configure a security
+ policy that suits your local environment.
+
+ As an analog to linear (RGB) and non-linear (sRGB) color colorspaces, as
+ of ImageMagick 7.0.7-17, we introduce the LinearGray colorspace. Gray is
+ non-linear grayscale and LinearGray is linear (e.g. -colorspace linear-gray).
+
+ Want more performance from ImageMagick? Try these options:
+
+ Add more memory to your system, see the pixel cache; Add more cores to
+ your system, see threads of execution support; push large images to a
+ solid-state drive, see large image support.
+
+ If these options are prohibitive, you can reduce the quality of the image
+ results. The default build is Q16 HDRI. If you disable HDRI, you use
+ half the memory and instead of predominately floating point operations,
+ you use the typically more efficient integer operations. The tradeoff
+ is reduced precision and you cannot process out of range pixel values
+ (e.g. negative). If you build the Q8 non-HDRI version of ImageMagick,
+ you again reduce the memory requirements in half-- and once again there
+ is a tradeoff, even less precision and no out of range pixel values. For
+ a Q8 non-HDRI build of ImageMagick, use these configure script options:
+ --with-quantum-depth=8 --disable-hdri.
