Hi there, there is a bug in the file "\Magick++\lib\geometry.cpp", in the function which generates a text string of the current geometry parameters (starts on line 277). // Return geometry string Magick::Geometry::operator std::string() const When generating the x & y offset text an ex...

Using the Magick++ api I've created two Magick::Image objects, cleared one to blue, and drawn a red square on the other. Both of these images have been saved out to disk to verify their contents, both are correct. The square is drawn directly into a pixel cache, setting the r,g,b, and opacity for ea...

Thank you for the clarification.

According to the documentation it looks like I can set EXIF data via the attribute function, however I can't get it to work. Spent the last hour googling around, and can't seem to find anything useful either, only suggestions of using another program to set the EXIF data. Writing image as a JPG, so ...

Ah ha! Thank you for the link. It would seem that the image constructor does not set the background color, what color it does set I have no idea. The documentation just states "Construct a blank image canvas of specified size and color". Can anyone shed any light on what "color" ...

Setting the background color via
makes no difference, the background still comes out being 205,205,205?

I'm not an expert on image magick, but I would assume that the binary download is exactly what the name suggests, i.e. statically linked, therefore does not contain any external library files in the download. Typically static linking will increase your total build time, not shorten it. It removes de...

As far as I can tell from the documentation the following code should produce a black image, with the red pixel in the center. // create image with dimensions of 320x200 pixels, set background color to black Magick::Image image( Magick::Geometry( 320, 200 ), Magick::Color( 0,0,0 ) ); // set pixel ro...

Thank you!

I agree, from the looks of the code calling modifyImage() should be the only function required.

Thank you again, this is great software!

Eureka! When using MagicCore functions on Magick++ image objects are any precautions needed to make the image object aware that the underlying image may have changed? From the looks of things, so long as I call modifyImage() before using the MagickCore function I should be fine? Magick::Image test_i...

What is the correct way to access the function BlackThresholdImage() in a c++ application? I'm starting to use Magick++, which does not appear to have this function. I can see the function in magick\threshold.cpp, but am unsure of the correct method of accessing this function. Googling around has no...
