How to pass argument for `includegraphics[width=..]..` without causing “Runaway argument?”?












0















I'm going to despair: It seems nobody has a problem when passing an argument for the width of includegraphics, but I always get Runaway argument?.
Whenever I remove the [#2textwidth] from my command definition, the command works!



My command looks like this (still room to improve):



newcommand{figcap}[5][htbp]{%
begin{figure}[#1]%
centering%
includegraphics[#2textwidth]{#3}%[width=#2textwidth]
caption{label{Lf{#5}}{small{}#4}}%
end{figure}
}


And my call is like this:



figcap{1}{1920px-Cone-....png}{Normierte ... (blau, grün, rot).}{test}


Using LaTeX2e <2017-04-15> I get this error:



Runaway argument?
1textwidth ]{1920px-Cone-....png}caption {label {Lf ETC.
! Paragraph ended before Gin@iii was complete.
<to be read again>
par


I've spend hours of reading and trying, but I don't find the problem.
The packages I'm using are:





documentclass[a4paper,draft,twoside]{report}
usepackage{german}
usepackage[latin1]{inputenc}
usepackage{a4}
usepackage{amsmath}
usepackage{url}
usepackage{graphics}


And before you ask: newcommand{Lf}[1]{fig-#1}
