 |
|
Hi everybody,
when I try to compile a program that uses image Magick++ lib, I get the following error:
error: argument of type `unsigned int (Magick::Image: ()
const' does not match `const unsigned int'
here is the code:
// new Image
Image glyph(bitmap.width,bitmap.rows, "K", CharPixel, bitmap.buffer);
// this leads to the error:
unsigned int const c = buchstabe.columns;
My first attempt was to use:
PixelPacket *pixel_cache = glyph.getPixels(0,0,glyph.columns,glyph.rows);
but then I get the error:
error: no matching function for call to `Magick::Image::
getPixels(int, int, <unknown type>, <unknown type>)'
/usr/include/Magick++/Image.h:1134: error: candidates are:
MagickLib::PixelPacket* Magick::Image::getPixels(int, int, unsigned int,
unsigned int)
Any help is very apreciated, because i'm stuck on this.

It's hard to know without seeing your header files, but could you be
neglecting to call a function?
That is, could it be that you need to write something like this?
unsigned int const c = buchstabe.columns();
where the parentheses say to call the function?

This seems the likely cuplrit.
The other (but unlikely) possiblity is that "columns" is a member
variable which is a function pointer.

Just a guess ... try this:
PixelPacket *pixel_cache =
glyph.getPixels(0,0,glyph.columns(),glyph.rows());
