From the C program, I/O always works like a charm. But starting today, my C++ program crashes when using a function that writes an image (written in C).
The odd thing is that , yesterday it was working perfectly. Another odd thing is, always get this error on the 4th invocation of the function. I have several invocations (like 10) and when I remove the one that gives problem, the next invocation crashes.
Below I post the function and the error. imatge_rgba is my image type, the aim of the function is just to write it to disk.
The functions code:
Code: Select all
#include <magick/api.h>
#include <string.h>
void imatge_rgba_save_magick(imatge_rgba *o, const char* filename)
{
XML_IN;
Image * image;
ImageInfo *image_info;
//MagickCoreGenesis(".",MagickTrue);
InitializeMagick(NULL);
image_info=CloneImageInfo((ImageInfo *) NULL);
//image_info=AcquireImageInfo();
//GetImageInfo(image_info);
image_info->depth=8;
image=AllocateImage(image_info);
if (image == (Image *) NULL)
MagickError(ResourceLimitError,"Unable to save image",
"Memory allocation failed");
strcpy( image_info->filename, filename );
strcpy(image->filename, filename );
image -> rows = (int)o->h;
image -> columns = (int)o->w;
image->depth=8;
PixelPacket *q;
float f=65535.0/255.0;
//float f=1;
rgba_value v;
for(int i=0;i<o->h;i++)
for(int j=0;j<o->w;j++)
