Yes the resolution type was 0 which is "UndefinedResolution". Even after setting PixelsPerInchResolution as the ImageUnits the result was still 0x0.

But when I do

identify -format "%xx%y" grass.png

I get the result as 118.10999999999999943x118.10999999999999943

Sorry for not mentioning the API I am using, You assumed correctly that I am using MagickWand functions. I used MagickGetImageResolution but I am getting result as 0.000000 x 0.000000. Please find my sample code below. double xx,yy; MagickGetImageResolution(wand, &xx, &yy); printf("ppi ...

Hey now I am a little confused of what I am doing. I will try to describe the scenario. Say I have an image of some dimension 100x100 pixels, I want to place some text in the center of this image and I want the text to cover 50% of the image's height leaving 25% space from both top & down, which...

I am currently using ImageMagick 6.8.9-10 version on linux. I want to get the image's ppi, is there a way to get this info using C api. Please help.

Thanks guys, I am able to achieve what I wanted from command line. I want to implement this in C I have figured everything out regarding how to implement this except I am not able to use compose method in C when I want to overlay a image on an background image, I am using https://www.imagemagick.org...

By my understanding annotate will just put text on an image of a defined size but I want the background with some transparency as well, if I set background it will set for the whole image which I don't want. I just want to have a small rectangle at the bottom of image with some color and transparenc...

Anyway I was able to set the transparency externally by using -alpha on -channel A -evaluate set 50% +channel But now I am stuck on another problem say if the text is small say just two letters then the text becomes very large and covers the whole width of image, cant we simply specify the font size...

What about this how can I fix for my ImageMagick version?

Ok that worked, this is essentially the alpha value is 0.5 which is making it translucent, cant we set transparency without using rgba color? Because in many instances I might have to use colors other than black, so I will prefer putting the color name as required and setting the transparency with s...

Thanks this worked well. I also want to know what is the best way to make the background of lower rectangle in the above image translucent or set some opacity to it. As well as for some reason, for me the text in the black rectangle is not center aligned its touching the upper edge of the rectangle ...

I was able to host this image and have shared the same in my old comment, here I am attaching again http://cdn.atomex.net/sample.png . In this sample image look at the top right corner there is a small black image on which discount is displayed. So I want to overlay that image on my original image a...

Sorry for not mentioning the platform I am using, I am doing all this on linux. I want the rectangle to cover the whole width of image and text should be placed in center. I also want to overlay a bookmark type small image on top right of my image and display some text in the center of that overlaye...

I have ImageMagick 6.8.9-10 version.

Please help in prototyping at command level I am not sure how I am gonna place the text in the center of rectangle or an overlayed image, I can find the corresponding C function later.

There are two things which I wanna do - 1. So I have an image, I want to draw a rectangle over it with some opacity and put some text in the center of that rectangle 2. Overlay a small image on the original image and then write some text in the center of that overlayed image. Text will be a dynamic ...
