How can I make this to work ?

The MagickWand interface is a new high-level C API interface to ImageMagick core methods. We discourage the use of the core methods and encourage the use of this API instead. Post MagickWand questions, bug reports, and suggestions to this forum.

How can I make this to work ?

Postby bibbou » 2011-04-25T11:41:16-07:00

Hey!

First of all I'am French, so sorry for my english!

I'am trying to run this program :

Code: Select all

#include <stdio.h>
#include <stdlib.h>
#include <wand/MagickWand.h>

int main (int argc, char **argv){
  MagickWand *mw;
  DrawingWand *dw;
  PixelWand *cw;
  MagickWandGenesis ();
  mw = NewMagickWand ();
  dw = NewDrawingWand ();
  cw = NewPixelWand ();
  PixelSetColor (cw, "white");
  MagickNewImage (mw, 640, 480, cw);
  DrawSetStrokeOpacity (dw, 1);
  PixelSetColor (cw, "red");
  DrawSetStrokeColor (dw, cw);
  DrawLine (dw, 100, 100, 200, 200);
  DrawSetFillOpacity (dw, 0.0);
  DrawCircle (dw, 200, 200, 250, 250);
  MagickDrawImage (mw, dw);
  MagickWriteImage (mw, "image.png");
  cw = DestroyPixelWand (cw);
  mw = DestroyMagickWand (mw);
  dw = DestroyDrawingWand (dw);
  MagickWandTerminus();
  return EXIT_SUCCESS;
}


I use the makefile below :

Code: Select all

CPPFLAGS=-I/usr/local/include/ImageMagick
LDFLAGS=-L/usr/local/lib -lMagickWand
all: wand-test
wand-test: wand-test.c
   gcc -o wand-test $< $(CPPFLAGS) $(LDFLAGS)
clean:
   rm wand-test


And I enter this in my console :

Code: Select all

bok@ubuntu:~/Documents/LC4/testM$ make
gcc -o wand-test wand-test.c -I/usr/local/include/ImageMagick -L/usr/local/lib -lMagickWand
bok@ubuntu:~/Documents/LC4/testM$ ./wand-test
bok@ubuntu:~/Documents/LC4/testM$ ls
makefile  makefile~  wand-test  wand-test.c  wand-test.c~


The problem is than nothing appears and no file is created !

Am I doing this wrong ?

Thanks in advance.

I can't see anything wrong with what you've done.
I compiled your program in Windows and it works just fine.

I'll try to help by adding some infos :

I'm running Ubuntu 10.10

To install i followed this : http://www.imagemagick.org/script/insta ... e.php#unix

And I installed [sudo apt-get install] libmagickwand-dev

Did i miss something?

Running this :

Code: Select all

typedef struct{
  int ageMinimum;
  int nbTotal;
  int nbHommes;
  int nbFemmes;
} trancheAge;

typedef struct{
  int id;
  char* nom;
  trancheAge* donnees; 
} pays;


Code: Select all

void pyramideAges(pays p,int annee,int colonne){
  MagickWand *mw;
  DrawingWand *dw;
  PixelWand *cw;
  int i;
  double largeurMax,largeur;
  MagickWandGenesis();
  mw = NewMagickWand();
  dw = NewDrawingWand();
  cw = NewPixelWand();
  PixelSetColor(cw, "white");
  MagickNewImage(mw, 600, 600, cw);
  DrawSetStrokeOpacity(dw, 1);
  PixelSetColor(cw, "black");
  DrawSetStrokeColor(dw, cw);
  DrawAnnotation(dw,10.0,15.0,p.nom);
  DrawAnnotation(dw,10.0,30.0,itoa(annee));
  printf("%d",colonne);
  switch (colonne){
    case NBTOTAL :
      DrawAnnotation(dw,10.0,45.0,"Population Totale");
      break;
    case NBHOMMES :
      DrawAnnotation(dw,10.0,45.0,"Population Masculine");
      break;
    case NBFEMMES :
      DrawAnnotation(dw,10.0,45.0,"Population Feminine");
      break;
    default :
      break;
  }
  largeurMax = maxPop(p,NBTOTAL);
  for (i = 1; i<22; i++){
    largeur = ((double) p.donnees[i].nbTotal)*(500.0/(double)largeurMax);
    DrawRectangle(dw, 300.0-(largeur/2.0), 500.0 - 20.0*i, 300.0+(largeur/2.0), 520.0 - 20.0*i);
  }
  MagickDrawImage(mw, dw);
  MagickWriteImage(mw, "image.png");
  cw = DestroyPixelWand(cw);
  mw = DestroyMagickWand(mw);
  dw = DestroyDrawingWand(dw);
  MagickWandTerminus();
}


I got those :

Fixed using this before install:

./configure --with-modules
