Yes imageMagick is a com object application.after install (mandatory),there is a dll named:
ImageMagickObject.dll
reigister it if not registered.

to create im com codes this is a basic example:

local m.yrep
m.yrep=addbs(justpath(sys(16,1)))   &&start folder
if !directory (m.yrep+"images")  &&images created  folder
md (m.yrep+"images")
endi

local m.xpict,imgObj
m.xpict=getpict()
if empty(m.xpict)
return .f.
endi

imgObj = CreateObject("ImageMagickObject.MagickImage.1")
= imgObj.Convert(xpict, "-resize", "100x100!", "images\thumb.png")
 = imgObj.Convert(xpict, "-resize", "200x200!", "-type", "Grayscale", "-depth", "8", "images\thumb_grayscale.png")
 = imgObj.Convert(xpict,"-negate", "-resize", "300x250!",  "images\thumb_negate.png")
 = imgObj.montage("-label","myShadow",xpict,':','-background','none','-geometry','+15+15','-shadow',  'images\shadow.png')
 = imgObj.montage (xpict,"-background","Gold","-flatten","-frame","6","-geometry","'64x64+10+10>'","-size","16x16","-bordercolor","LimeGreen","-background","SeaGreen","images\ymontage_texture_border.gif")
 = imgObj.convert(xpict,":","-raise","12","images\yraise.gif")
imgObj=null

to work with images,can receive all IM command lines as
-convert
-montage
-composite
..........
it can works with command lines.

Infortunatly there is no great backward compatibility between versions.i worked with old ImageMagick-6.8.8-Q16 version ( must adapt all codes shipped in the zip pointed above to make it working with recent versions).

update: i downloaded the latest version ImageMagick-7.0.1-Q16 and i dont found the ImageMagickObject.dll as in version 6.8.8 Q16.
