我正在使用来自艾琳娜·波托耶娃创建 A0 海报。如何将背景更改为颜色渐变，我尝试更改样式文件，但无法使其工作。
答案1
\setbackgrounddarkcolor在、 和中设置所需的颜色\setbackgroundlightcolor。在以下示例中，我使用了
\setbackgrounddarkcolor{cyan!70!black}% ORIGINAL: colorone!70!black
\setbackgroundlightcolor{orange!70!black}% ORIGINAL: colorone!70!

Macro for creating a block node:
\begin{itemize}
\item[] \textbackslash blocknode\{Block Title\}\{Block Content\}
\end{itemize}
Macro \textbackslash blocknode has three parameters. The first one is
optional and it is the position of the block. The first block will be
automatically placed to (\$(firstrow)-(xshift)-(yshift)\$), which is the
left corner below the title block. In most of the templates, (firstrow) is
set to (title.south), where \emph{title} is the alias for the title
block. Each subsequent block is automatically placed to
[(\$(box.south)-(yshift)\$)], i.e., below the previous block aliased
\emph{box}. You can also use an explicit parameter, e.g., $(-10,30)$ (note
that (0,0) is the center of the poster). The second parameter is the title
of the block. Finally, the last parameter is the actual content.
}
%% by default, the position of the new block node is right below the previous
%% block node, stored in (currenty)
%% box is the alias of the previous block, so we can refer to its boundaries
%%%%%%%%%% ------------------------------------------ %%%%%%%%%%
\blocknode{Making Title}%
{To make title, use the standard commands \textbackslash title and
\textbackslash author in the preamble, and then the following macro:
\begin{itemize}
\item[] \textbackslash titleblock\{50\}\{1.5\}
\end{itemize}
Macro \textbackslash titleblock has three parameters. The first one is
optional and it specifies the shift of the title block w.r.t.\ its default
position, which is set to (\$0.5*(0,\textbackslash
paperheight)-(0,\textbackslash margin)\$). The second parameter is the width
of the title block, and the third parameter is the scaling ratio (to make
the title bigger or smaller).\\
\small
The syntax for specifying authors is similar to the one in aaai.sty. Author
information can be set in various styles: For several authors from the same
institution:
\begin{itemize}\item[]
\textbackslash author\{Author 1 \textbackslash and ... \textbackslash and
Author n \textbackslash\textbackslash\\
Address line \textbackslash\textbackslash ... \textbackslash\textbackslash \ Address line\}
\end{itemize}
If the names do not fit well on one line use
\begin{itemize}\item[]
\textbackslash author\{Author 1 \textbackslash\textbackslash \{\textbackslash bf Author 2\} \textbackslash\textbackslash ... \textbackslash\textbackslash \{\textbackslash bf Author n\} \textbackslash\textbackslash\\
Address line \textbackslash\textbackslash ... \textbackslash\textbackslash \ Address line\}
\end{itemize}
For authors from different institutions:
\begin{itemize}\item[]
\textbackslash author\{Author 1 \textbackslash\textbackslash \ Address
line \textbackslash\textbackslash \ ... \textbackslash\textbackslash Address line \\ \textbackslash And ... \textbackslash And \\
Author n \textbackslash\textbackslash \ Address line
\textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
line\}
\end{itemize}
To start a separate ``row'' of authors use \textbackslash AND, as in
\begin{itemize}\item[]
\textbackslash author\{Author 1 \textbackslash\textbackslash \ Address line
\textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
line \textbackslash AND\\ Author 2 \textbackslash\textbackslash \ Address line
\textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
line \textbackslash And\\ Author 3 \textbackslash\textbackslash \ Address line
\textbackslash\textbackslash \ ... \textbackslash\textbackslash \ Address
line\}
\end{itemize}
(though, I must say \textbackslash and ... \textbackslash and did not work for
me with more than 2 authors, so just use commas where you need if it does
not work for you either).

\blocknodew[($(currenty)-(3.5,0)$)]{30}{Variable Width Block Nodes} %
{ You can also create blocks of arbitrary width
\begin{itemize}
\item[] \textbackslash blocknodew[coordinate]\{Block width\}\{Block Title\}%
\{Block Content\}
\end{itemize}
%
In this case it is better to specify coordinate manually if you want to have
blocks aligned vertically. \\
Note that (xshift) and (yshift) are coordinates created in macro
\textbackslash initializesizeandshifts, and they allow to have relative
positioning of block nodes in an automatic fashion. If you want to define
your own shifts, set new values for (xshift) and (yshift) using commands
\textbackslash setxshift and \textbackslash setyshift.\\
Also, it might be useful to know the y-coordinate of the south border of the
previous block. You can retrieve it by using the command
\begin{itemize}
\item[] \textbackslash getcurrentrow\{box\} or \textbackslash getcurrentrow\{note\}
\end{itemize}
This coordinate will be stored in (currentrow), which can be used to
specify the location of the next block node.

\begin{itemize}
\item[] \textbackslash startsecondcolumn, and \textbackslash startthirdcolumn.
\end{itemize}
If the number of columns is 2, then the last command will not have
effect. \\
You can also start a new column with an arbitrary x-coordinate by specifying
explicitly the coordinate of the new block node as follows:
\begin{itemize}
\item[] \textbackslash blocknode[(\$(firstrow)-(yshift)+(x,0)\$)]\{Block
Title\}\{Block Content\}
