If your command below is not good color quality
No no, the color with this command is okay for me. I'm just asking how to do the same that -colorspace sRGB does but with Magick++.
But if it not possible, then something similar.



With profiles and assuming the pdf is CMYK like the jpg, use ...

I should've give this links of the images instead:
Image 1
Image 2

Just to clarify, this is the image I get if convert a pdf to an image using imagemagick without -colorspace sRGB .
It is also what I get if only open the pdf and save it using magick++
convert -density 72 -quality 90% Blender.pdf[0] Blender.jpg

Thanks for your reply,
I update my imagemagick and is now 6.9.0-0, or at least that is what says convert -version:

Hi everyone,

when I convert a pdf to an image the value and saturation seems wrong, but by adding -colorspace sRGB corrects the output image. Now I want to do the same in magick++ but I can't find the equivalent procedure.

I already try with colorSpace(sRGBColorspace) but it does nothing. Does ...

Thank you very much for the tip! Now rowstride has the value that should (image width * number of bits per pixel), and that solved the problem :D

Here's a function that takes a Magick::Image object and returns a Gdk ...

After more searching I found this

So I took advice and changed the code to:

#include <Magick++.h>
#include <gtkmm.h>
#include <iostream>

using namespace std;
using namespace Magick;

class MyArea : public Gtk::DrawingArea
{
public:
MyArea();
virtual ~MyArea();

protected:
//Override default ...

Solved: I just forgot the magic word "Magick::"

When trying to obtain the RGB data with:
image.write(0, 0, width, height, "RGB", CharPixel, data);
I get an error while compiling:
main.cpp: In constructor ‘MyArea::MyArea()’:
main.cpp:51:44: error: ‘CharPixel’ was not declared in this scope
image.write(0, 0, width, height, "RGB", CharPixel ...

Hello everyone,

I was for a while trying to load this image file with Magick++ and then show it in a simple GTK app.

But in my attempt I get a runtime error of GTK when load a blob in a pixbuf.

Here's my code until now:

#include <Magick++.h>
#include <gtkmm.h>
#include <iostream>

using ...
