Question

我有以下代码：

if($tip_dente == 2){
    for($i=0; $i<=7; $i++){
        if(in_array($array_p1n[$i], $array_denti_new)){
            $pdf->Cell(0.5,1,$pdf->Image($array_p1[$i],$pdf->GetX(),$pdf->GetY(),0,1,'PNG'),1,C,1,false); // larghezza, altezza, txt, bordi, linea a capo, allineamento orizzontale, riempimento colore, ignorare
            $pdf->Cell(0.2,1,'',0,0,C,false);
        }else{
            $pdf->Cell(0.5,1,$pdf->Image($array_p1[$i],$pdf->GetX(),$pdf->GetY(),0,1,'PNG'),0,C,1,false); // larghezza, altezza, txt, bordi, linea a capo, allineamento orizzontale, riempimento colore, ignorare
            $pdf->Cell(0.2,1,'',0,0,C,false);
        }
    }
}

除了一件事，一切都很美妙。第一行似乎添加了额外的空间：

如何摆脱这个额外空间？

Answer 1

虽然我无法使用我的系统上的控制代码进行测试，但在此文本之后您很可能需要\n：

printf(Y "\n\n\"IT'S PEANUT BUTTER JELLY TIME\"\n" D);

至少，这在Windows系统上解决了同样的问题（Y和D似乎是颜色控制代码，所以这不应该影响位置。< / p>

<强>更新：

似乎也存在position control code（虽然不能在这里测试）：

#define     GOTOYX   "\x1B[%.2d;%.2dH"
    Set cursor to (y, x). More...

因此，您可以使用此代码来定位第一行而不是额外的换行符。

Answer 2

尝试在第一行之前插入\n字符。

Answer 3

我;在ubuntu linux 14.04上使用gcc进行编译。

以下代码可以干净地编译并执行所需的操作。

我无法使\1b[2j（清晰屏幕）工作，并发现我不需要它。

一些重大变化是

以\n结束每个图形的最后一行，因此最后一行始终立即输出
将图形修改为全部宽度和高度相同
将if(true)语句修改为在彩色和纯文本输出之间交替
删除了对fflush()
图形第一行的错误偏移的原因是没有使用正确的间距来允许图形中一行开头的w而不输出整个图形输出而不是全部图形具有相同的高度/宽度。

以下代码是结果

#define _GNU_SOURCE
#include <stdio.h>
#include <unistd.h>
#include <stdbool.h>

#define D "\x1b[0m"
#define Y "\x1b[33;1m"
#define W "\x1b[37;1m"
#define B "\x1b[30;1m"
#define CURSOR_1_1 "\x1b[1;1f \n"
