在solaris 10中生成的图片文件在windows中打开后显示不正常

[xlstc7]

用的第三方图形库是cximage或GD，同样的代码在windows下编译运行后生成的图片打开后能正常显示，可是在solaris 10下编译后运行生成的图片，拿到windows中打开后显示的却是一些乱七八糟的颜色，cximage和gd的源码都是直接从官方下的最新版本，测试gd时用的示例代码也是官方的。在另一个分论坛有人拿我的代码去他的环境中试，据说是可以在windows中正常显示的，不清楚他用的是什么系统，可能是linux吧。不清楚是不是跟solaris的环境或者别的什么什么有关。我的solaris没针对图形装过其它什么东西。

以下是GD的示例代码：

#include "gd.h"
#include "gdfontl.h"
#include <string.h>
#include <stdio.h>

int main(int argv, char** argc)
{ 
	/* Declare the image */  
	gdImagePtr im;  
	/* Declare output files */  
	FILE *pngout, *jpegout; 
	/* Declare color indexes */
	int black;  int white;
	/* Allocate the image: 64 pixels across by 64 pixels tall */

	im = gdImageCreate(64, 64);
	/* Allocate the color black (red, green and blue all minimum).    Since this is the first color in a new image, it will    be the background color. */
	black = gdImageColorAllocate(im, 0, 0, 0);
	/* Allocate the color white (red, green and blue all maximum). */
	white = gdImageColorAllocate(im, 255, 255, 255);
	/* Draw a line from the upper left to the lower right,    using white color index. */
	gdImageLine(im, 0, 0, 63, 63, white);
	/* Open a file for writing. "wb" means "write binary", important    under MSDOS, harmless under Unix. */
	pngout = fopen("test.png", "wb");
	/* Do the same for a JPEG-format file. */
	jpegout = fopen("test.jpg", "wb");
	/* Output the image to the disk file in PNG format. */
	gdImagePng(im, pngout);
	/* Output the same image in JPEG format, using the default    JPEG quality setting. */
	gdImageJpeg(im, jpegout, -1);   /* Close the files. */
	fclose(pngout);
	fclose(jpegout);  
	/* Destroy the image in memory. */
	gdImageDestroy(im);
}
