# Use proper background.index when writing indexed PNG, if the background color is in the palette.
# Fix improper 'invalid colormap index' PNG bug.

# Remove any prior resolution block from PSD before writing the new block.
# Addition of more Morphological/Convolution Kernels. DOG (Difference of Gaussians) and DOB (Difference of Blurs), Prewitt, Roberts, Compass, and Ring
# The pixel buffer was underallocated for some image formats when streaming.

# Third Re-write of MorphologyApply() to better handle compound methods.
# Implemented -set option:morphology:compose for merging results of multiple kernels. "None" means re-iterate results with next kernel. While "Undefined" means to use the internal default for a method. Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None" while HitAndMiss defaults to "Lighten" (union of all kernel results). Other morphology methods defaults still to be decided.
# Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
# Rotation Expansion of single kernels '^' and '@' flags in arguments EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
# ExpandKernelInfo() (rotation expand) now groks symmetrical kernels. So the above will only produce a list of 2 kernels, not 4 kernels
# Separation of internal function MorphologyAppy() from MorphologyImageChannel() to calls to convolve without user settings.
# Rewrite of MorphologyApply() to output better 'verbose' messages
# Better handling of Gaussian tyle filters (bug fixes)
# Bug fix and optimization of kernel size calculations in "gem.c"
# Allow '^' or '@' flags in 'user defined' kernel size arguments to expand kernel into a rotated list. EG: -set option:showkernel 1 -morphology Thinning '3@: 0,1,0 0,1,0 0,0,0'
# Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen) EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
# Addition of "Laplacian of Gauussian" (LOG), also known as Mexician Hat EG: -morphology convolve LOG:0x1
# Added FreiChen, Kirsch Convolution kernels
# Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)
# Added Edges HitAndMiss Kernel
# PSD images require a proper layer to support an alpha channel.
# Enable PFM endian support.
# Add context to -border for montage. Inside the parenthesis it adds a border to the image otherwise it sets the border for the layout manager.
# 24-bit BMP images are not colormapped even if header colors != 0.
# Set DPX user data like this: -set profile dpx:userdata.txt.
# Make sure Lab => RGB => Lab survives the round trip.

# Prevent coders/png.c from attempting to write an empty tRNS chunk.
# Finish for Square Array Rotates (off center origin rotate)
# Added HitAndMiss kernel Ridges2 to find 2 pixel thick ridges
# Added FreiChen:0,{angle} FreiChen:{angle} and FreiChen:-1 variations to complete this kernels definition
# Respect density when rendering SVG images.
# Set AVI handler to the MPEG coder.
# Compute the proper DPX user data field size.
# Do not interpret a format specifier when enclosed in brackets (e.g. rose_tile_%[filename:tile].gif.
# Use 64-bit types when compiling with the 64-bit Visual C++ compiler under Windows.
# Prevent MNG divide by zero (refererce http://www.imagemagic...p?f=3&t=16320).

• Replaced '^' morphology kernel rotation with two varients '>' and '<'
• Hopefully finally settled the kernel defintion of 'Skeleton' to correctly thin down ANY starting image, as symetrically as posible.
• Spelling correction: Manhatten -> Manhattan
• Properly scale color components of the PNG bKGD chunk.
• Prevent MNG divide by zero in calculation of frame_timeout. Set both frame_delay and frame_timeout to infinite when ticks_per_second is zero, as required by the MNG spec.
• Add x:silent option to prevent beeps when reading the X image format.
• Recognize TTF for GetMagicInfo().
• Ensure the +set option deletes the image artifact.

• Don't decode pixels in coders/png.c when image->ping is set.
• Reset image filename when reading inline images.
• Don't clamp floating point values for HDRI-enabled ImageMagick.

• Fix transprancy handling for Morphology Convolve
• Adjustments of Hit And Miss and Edge Detection kernel definitions
• Added 'ThinDiagonals' Thinning Kernel + two sub-types
• Handling for Convolution of 1-D vertical kernels. However this was removed (using #if-#endif) as I found it slower in tests!
• mogrify -format properly handles compressed image filename (e.g. -format jpg logo.png.bz2).
• Respect +dither option when saving to the GIF image format.

# Support new label:pointsize property.
# Miscellany->Slide Show, in the display program, now cycles through the image sequence.
# Recognize certain hex color values (e.g. #b9e1cc00) for the -fx argument.
# Reduce memory requirements when dithering on the iPhone.
# Command line operators no longer affected by settings that appear after them (e.g. -splice 10x0+0+0 -gravity center).
# Compute the proper DPX user data field size.
