Sybase图像数据类型 [英] Sybase image data type

问题描述

大家好:

是否在sybase中将图像数据类型转换为字节数组?我应用Web服务来获取sybase(图像数据类型)中的数据集.我使用byte []获取Web服务的返回.然后，我使用"response.binarywrite(byte [])"显示图像.(ASP.NET C#)但是存在图像失真问题(当我在图像中放大时，会丢失一些点).我不知道为什么有人知道sybase中的图像数据类型可以传输到字节数组吗?

非常感谢.

Hello everyone:

Does image data type be converted to byte array in sybase? I apply web service to get data set in sybase( image data type). I use byte[] to get returning of web service. Then i use the "response.binarywrite(byte[])" to show the image.(ASP.NET C#) But there'' s a image distortion problem (When i zoon in the image, some points are missed). I don''t know why Does anyone know the image data type in sybase could be transfered to byte array?

Thank you very much.

推荐答案

除非您将数据作为BMP传递，否则获得可见的图像数据但错过了一些像素的几率接近零.文件.如果是jpg或png，则表示已压缩，如果损坏，则根本无法打开.

The odds of you getting image data that is viewable, yet misses some pixels, is close to zero, unless you''re passing data as a BMP file. If it''s a jpg or png, then it''s compressed, if it''s corrupted, you won''t be able to open it at all.
