- Bugs
- mjr::ramCanvasTpl::expandCanvas. Fixed a bug with monochrome
images. Changed the behavior when x1 or y1 is off the
canvas. Fixed a bug with non-zero x1 argument.
- Swapped mjr::ramCanvasTpl::rotate90CW &
mjr::ramCanvasTpl::rotate90CW
- mjr::ramCanvasTpl::autoMaxHistStrech(). Fixed bug when RGB were not
on default channels.
- New functionality
- ramCanvasTpl::getCanvasWidD()
- New canvas converter: rcConverterMonoIntensity
- ramCanvasTpl::adjoinCanvasRight()
- ramCanvasTpl::adjoinCanvasLeft()
- ramCanvasTpl::adjoinCanvasBottom()
- ramCanvasTpl::adjoinCanvasTop()
- ramCanvasTpl::insertCanvas() -- insert a canvas into another canvas
- mjr::sgn() -- the sign function
- mjr::point2d now has a conversion operator for complex numbers
- ramCanvasTpl now has coordinate conversion methods that work
with point2d allowing code like this:
std::complex<double> c = theRamCanvas.int2real(x, y);
- mjr::ramCanvasTpl::int2real
- mjr::ramCanvasTpl::real2int
- mjr::fmtInt(int inInt, int width, char fill) -- Strings with
formatted integers in them. Someday when compilers support the
C++20 formatting features, we won't need this...
- colorTpl::distDeltaE1976(colorArgType aColor) -- The LAB Delta E*(1976) distance
- colorTpl::distDeltaE1994(colorArgType aColor) -- The LAB Delta E*(1994) distance
- Real coordinate overloads for:
- ramCanvasTpl::drawHersheyGlyph
- ramCanvasTpl::drawString
- ramCanvasTpl::drawStringBox
- Polynomial routines
- mjr::evalBiPoly -- bivariate polynomial evaluation
- mjr::maxExpBiPoly -- figure out maximum theoretical exponent of a bivariate polynomial
- mjr::evalUniPoly -- univariate polynomial evaluation
- New log transformation function colorTpl::tfrmLn(double scale) -- note new name for
the old version of this function: tfrmLn1()
- API Change
- colorTpl::tfrmLn() renamed to tfrmLn1()
- ramCanvasTpl::autoMaxHistStrech renamed to autoMaxHistStrechRGB
- Updated/New experimental geometric transformations functionality (geomTfrmRev* methods)
These feel like they are approaching a final state, but I'm going to keep them classified
as "experimental" for now.
- Fixed a clipping bug for existing geomTfrmRef functions:
- ramCanvasTpl::geomTfrmRevRPoly
- ramCanvasTpl::geomTfrmRevAff
- ramCanvasTpl::geomTfrmRevArb
- Transform methods now take a uniform set of shift & scale arguments:
- Xo -- X coordinate for the offset from image center.
- Yo -- Y coordinate for the offset from image center.
- oScale -- Scale to apply after transform but before reverse translation
- Started making some unit tests for mjrmath.hpp. Coverage right now is just for the new
polynomial routines.
Feature Release

- https://www.mitchr.me/SS/mandelbrotBiomorph/index.html
- https://www.mitchr.me/SS/mandelbrotInv/index.html
- Updated examples:
- sic.cpp -- Updated the comment on the colorizer object to
reference another way to do the same thing illustrated in the
pickoverPopcorn.cpp example.
- biomorph2.cpp & biomorph1.cpp -- Cleaned up the way colors were
set.
- mandelbrot_bm_real.cpp & mandelbrot_bm_real_eqop.cpp -- Fixed
typos in header.
- New feature:
- ramCanvasTpl::rcConverterColorScheme -- Colorize a ramCanvasTpl
with integer channels using a color scheme. This gives one the
ability to produce a ramCanvasTpl with some data in it, and then
colorize it when the image files are written out. For example,
we could store the L function for a Mandelbrot render in a
grayscale image, and then write out any number of RGB images
with different color schemes.

- colorTpl::csCCu0B -- Ramp from black to blue
- colorTpl::csCCu0G -- Ramp from black to green
- colorTpl::csCCu0C -- Ramp from black to cyan
- colorTpl::csCCu0M -- Ramp from black to magenta
- colorTpl::csCCu0Y -- Ramp from black to yellow
Unit tests. New features.

Release Candidate #3
- Last time I removed the filter option from the file write APIs,
and that annoyed some people. ;) So I have added filters back, but
the new filters are more capable in that they can be used for not
just homogeneous transforms but geometric ones too.
- Removed: pixelFormatEnum
- New converter classes inside ramCanvasTpl:
- ramCanvasTpl::rcConverterIdentity
- ramCanvasTpl::rcConverterRGBbyte
- ramCanvasTpl::rcConverterRGBAbyte
- ramCanvasTpl::rcConverterRGBdbl
- ramCanvasTpl::rcConverterRGBAdbl
- convertRawToTIFF.cpp illustrates the new API
- New: "Canonical Color Types" -- color types with unsigned byte and
floating point channels in RGB, RGBA, and numChan. These provide a
handy interface for conversions with the two most common channel
types people use, and are useful for working with external
interfaces.
- Set color from a canonical color type
- colorTpl& colorTpl::setChans_dbl(colConALLdbl dblColor)
- colorTpl& colorTpl::setChans_byte(colConALLbyte byteColor)
- colorTpl& colorTpl::setChansRGBA_dbl(colConRGBAdbl dblColor)
- colorTpl& colorTpl::setChansRGB_dbl(colConRGBdbl dblColor)
- colorTpl& colorTpl::setChansRGBA_byte(colConRGBAbyte byteColor)
- colorTpl& colorTpl::setChansRGB_byte(colConRGBbyte byteColor)
- convert color to a canonical color type
- colConALLdbl colorTpl::getColCon_dbl()
- colConALLbyte colorTpl::getColCon_byte()
- colConRGBAdbl colorTpl::getColConRGBA_dbl()
- colConRGBdbl colorTpl::getColConRGB_dbl()
- colConRGBAbyte colorTpl::getColConRGBA_byte()
- colConRGBbyte colorTpl::getColConRGB_byte()
- typedefs for canonical color types
- colorTpl::colConRGBdbl
- colorTpl::colConRGBAdbl
- colorTpl::colConRGBbyte
- colorTpl::colConRGBAbyte
- colorTpl::colConALLdbl
- colorTpl::colConALLbyte
- New integer axis orientation predicates
- ramCanvasTpl::isIntAxOrientationNaturalX()
- ramCanvasTpl::isIntAxOrientationNaturalY()
- New helpers to guess named channel. These are helpful when
we have a color with unknown structure, and want to get the
best option for a named color channel.
- colorTpl::bestRedChan()
- colorTpl::bestGreenChan()
- colorTpl::bestBlueChan()
- colorTpl::bestAlphaChan()
- Unit tests
- colorTpl::colCon*
- colorTpl::best*Chan
- sic.cpp now uses the filter instead of making a new ramCanvasTpl
object -- like it did in the past.
- Added DO_CIRCLE to bmark.cpp
- Doxygen tag files & links into doxygen docs.
- Unit tests for ramCanvasTpl simple geom transforms
Bug fixes. Unit tests. New features. Better platform support.
Details
Release Candidate #2
- Bugs:
- ramCanvasTpl::writeFile
- Failed to pass return code from stream write helper function.
- Potential beyond buffer access
- New features:
- ramCanvasTpl::readRAWfile
- Breaking Changes
- Replaced the toTRU & filter arguments with an enum to convert to
8-bit RGB/RGBA. In addition, writeTIFF* no longer has an alpha
argument -- the enum takes care of that too.
- Unit tests for ramCanvasTpl now use isEqual and readRAWfile instead
of comparing file content.
- Platform Support
- Tested with several OS/compiler combinations
- Windows with MSVC, MSYS2 MSVC, MSYS2 clang, and MSYS2 GCC
- Debian 11 with GCC-10, and GCC-11
- MacOS with Apple clang and homebrew GCC
- Made several little code changes for better platform support.
- The big change is a couple of macros controlling conditional
compilation of code. This allows the code to be compiled, with
some reduced functionality, using some older compilers.
- Added a couple of conditional compiles:
- MISSING_P0476R2 -- Omits code using bit_cast
- MISSING_P1907R1 -- Omits code using floating point template parameters
- Added cmake rules for conditional code:
- Detect GCC version and set MISSING_P0476R2 & MISSING_P1907R1 as required.
- Set MISSING_P1907R1 for clang (both regular and Apple)
- Set MISSING_P0476R2 for Apple clang

- Better support for msys2 on windows:
Added options in CMakeLists.txt to make GLUT, FLTK, & SDL2 code be
compiled as a "GUI" application instead of a "console" application
as before. The console applications would fail to open a window
when run within some contexts. I may need to do something for
MSVC too, but I don't know as much about that environment...
- Color documentation (ColorSchemes.org)
- Added binary pallets
- Added three segment CC diverging color schemes
- Added continuous swatches to fixed pallets
- Added cross reference

Refactor, Bug Fixs, Unit Tests
Details
Still beta. Still a few API changes, but things are stabilizing.
Please test and report back!
- Tons of unit tests
- Rearranged some code in colorTpl for better Doxygen results.
- colorTpl::csFP_tpl now provides both discreet and continuous color
schemes via overloads to the c member. Much like csCB_tpl.

- When clrChanT wasn't uint8_t, this function would scale the
components incorrectly. Not sure this is really a bug as "web
safe" doesn't really apply to such images. Still, it's fixed.
- Now only operates on the red, blue, and green channels.
- colorTpl::intensityScaledRGB
Scaling was incorrect for images with more than 3 channels.
