Re: On compiling ImageMagick 6 and 7 using Mingw64

Also, some libraries such as "tiff" are rejected by IM6/7's configure. It happens only for TDM-GCC's Mingw64, but not its Mingw32 or xvidvideo.ru's GCC build.

On compiling ImageMagick 6 and 7 using Mingw64

First, I downloaded a) MSYS from http://sourceforge.net/apps/trac/mingw-w64/wiki/MSYS b) Mingw64/GCC 4.7.1 from http://tdm-gcc.tdragon.net/ c) Supporting libraries (all in .tar.gz): zlib-1.2.7, bzip2-1.0.6, xz-5.0.4, jbigkit-2.0, libjpeg-turbo-1.2.1, libpng-1.5.12, tiff-4.0.3, libxml2-2.9.0, fftw-3....

Re: ImageMagick 7 Windows builds?

Just managed a V6 Win32 compile with turbo-jpeg, png, tiff, xml, fftw, HDRI and multi-thread using TDM-GCC 32-bit. I dunno that it could be so difficult..... :shock:

Missing #include in MagickCore/nt-base.h of ImageMagick 7?

I seem to have solved some compilation errors (mingw 4.6.3 x86_64) after I added an extra #include in MagickCore/nt-base.h, i.e.,

Code: Select all

#include "MagickCore/geometry.h"
.... to ....

Code: Select all

#include "MagickCore/exception.h"
#include "MagickCore/geometry.h"
Is it a typo?

Re: best downsampling method for DSLR photographs

I wanna speak the same language with you and so I am trying to compile ImageMagick v7 under mingw x64. But it's not as easy as I thought.... :(

I have always been advocating the direct use of EWA-Lagrange or even EWA-Catrom down-sampling instead of downsampling-then-USM. 8)

Re: The quality of re-sized image is not good

The wargame picture is a line art and it is up-sized by a few pixels only (474 -> 480). I think linear EWA Lanczos3Sharpest does the job very well. convert wargame.png -colorspace RGB -define filter:filter=Jinc -define filter:window=Jinc -define filter:lobes=3 -define filter:blur=0.88549061701764 -d...

Re: line drawings to test downsizing methods

EWA Lanczos3Sharpest offers more pronounced darkness differences in the gray "areas".
EWA Langrange, at this round, hurts the picture because its strong dark-halos are darkening the lines too much.
