I need to Image magick ++ for converting BMP to JPG ( in memory)


So, first requirements that I need to fullfill is these...

1) There is no root priviliges
2) It must work by coping pasting to any other linux based system (on other system directory differs)
3) I need to support bmp to jpeg conversion
4) Settings environment variables is possible (like $MAGICK_HOME)


I done lot of googling and so else but still did not founded right way ( u could say that I am bit novice to linux)

So here what I got... this one worked for me until I tried copy pasteto other system:

http://studio.imagemagick.org/pipermail ... 16371.html // by that configuration everything worked fine there (also i unistalled previus version of magick image that have been before so it may be possilbe that jpeg conversion left from there)


so i made some code it worked...

but when i transferedeverything to other system... puted LD_LIBRAR_PATH and MAGICK_HOME variablesi got error:

terminate called after throwing an instance of 'Magick::ErrorMissingDelegate'
what(): Magick: no encode delegate for this image format `blog.jpg' @ error/constitute.c/WriteImage/1157


it is because it do not get jpeg delegates (coder/ modulers)... but they files are in the system (jpeg.so and all other kind stuff)...
so identity gives(but MOGRIFY WORKED FINE! in jpeg conversion):

we have to keep in mind that here variables like PREFIX are wrong, but if I set it correct in batch before launching program it should work just fine.... ( I used Eclipse to build program)

may be there is even way to make all those needed parts static and put to eclipse ... but i had trouble with that (all errors about references and other erorrs..)

i guess for command line (configuring) it should look like smth:

./configure --disable-shared --enable-delegate-build --with-quantum-depth=16 --prefix=`pwd` --exec-prefix=`pwd` --disable-installed

also by this line jpeg conversion will not be supported how to make this static???


any help will be highly appreciated!

also I will give feedback on this so many will can learn get something with it.


also code lines that use:
Blob blob( testPicture.str().c_str(), sizeof(HEADER)+2+size);
Image image( blob);
image.magick("JPEG");
image.write("blog.jpg");

everything compiles and worked on first linuxplatform
here workfine two if do just BMP writing with no compresion...



I guess thebest idea would be load jpeg delagate module from eclipse... But how ?


Really waiting for somehelp...

so no one didi it before and no one knows how to do it ?

See Note from the "Architecture" Document on the IM Web site.

Or look at my own raw notes on this in....
http://www.cit.griffith.edu.au/~anthony ... gick.hints

Basically their are two forms of IM. 'Installed' (system) and 'non-installed' (personal)

One requires an environment variable MAGICK_HOME to find everything, the other does not.

Note I have multiple versions of IM installed on my system. A system installed and a special HDRI version I use for things like Fast Fourier Transforms. To call that latter one I have a special wrapper script, called "hdri"
I use the above like... or even It sets up environment, and a quick test such as

Version: ImageMagick 6.6.2-4 2010-06-08 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC
Features: HDRI

confirms I am using the special HDRI version of IM I built and installed into "/opt/im_hdri"
(set in the "configure" using --prefix)

However if my HDRI version of IM is not installed, it will automatically fall back to the normal IM 'convert' command.

NOTE I do not need to modify any other shell scripts, as the environment will be passed on into that script. Thus I can use a script with either versions of IM to compare results. However that will not work for PHP, unless the PHP script is modified to call the wrapper script itself.

so as far as I understood i have to install it normaly with sudo with enverinment parametre

$EXPORT MAGICK_HOME="path to dir"

and to configure it with parameter ./configure --prefix=$MAGICKhome (another parameters)

after this i have to unistall it and i will have portable image magick binary with all delegates (coders)?

You do not need sudo.

You can install with a configure --prefix setting to somewhere you can write.

I connected several parts of "How to install Image magick" and this is what I got...

First you need to download delegates... I needed just jpeg... as without administrator (root) rights i fo this for delegate installation
(you can obtain it from http://www.imagemagick.org/download/delegates/ or http://www.ijg.org/)

cd /home/ubuntu/libs/ImageMagick-6.6.3-0/external/jpeg-8b
./configure --prefix='/home/ubuntu/libs/jpeg' --enable-shared --enable-static
make
make install


so image magick installation part; after downloading and extracting ImageMagick

cd '/home/ubuntu/libs/ImageMagick-6.6.3-0'

export LD_LIBRARY_PATH='/home/ubuntu/libs/jpeg/lib' // this one just in case
./configure --prefix='/home/ubuntu/libs/magick' --enable-shared --without-x CPPFLAGS=-I/home/ubuntu/libs/jpeg/include LDFLAGS=-L/home/ubuntu/libs/jpeg/lib
make
make install

// adding image magick to library path
LD_LIBRARY_PATH=/home/ubuntu/libs/magick/lib:$LD_LIBRARY_PATH



now you can feel free to program in c++(imagemagick++) do a lot of stuff and port it to another computer....

I strongly believe that this one "tutorial" should published somwhere on your site (image magick) for making ImageMagick with delegates without root rights... If you do this it would be nice if you would mention me
