在C#上将raw文件转换为bmp文件，并保存

System.Drawing.Image original_image = null

System.Drawing.Bitmap final_image = null

System.Drawing.Graphics graphic = null

original_image = System.Drawing.Image.FromStream(jpeg_image_upload.InputStream)

final_image = new System.Drawing.Bitmap(target_width, target_height)

graphic = System.Drawing.Graphics.FromImage(final_image)

graphic.FillRectangle(new System.Drawing.SolidBrush(System.Drawing.Color.Black), new System.Drawing.Rectangle(0, 0, target_width, target_height))

int paste_x = (target_width - new_width) / 2

int paste_y = (target_height - new_height) / 2

graphic.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic/* new way */

graphic.DrawImage(original_image, paste_x, paste_y, new_width, new_height)

final_image.Save(strPath + strNewFileName, System.Drawing.Imaging.ImageFormat.Bmp)

思路就是读取到文件流中，然后按照mageFormat.Bmp重新保存

一般而言raw文件也分彩色和黑白的。彩色的弊蠢需要对每一个像桥卜者素进行差值运算（bayer算法，这个抱歉我不能开源）。还原成24或者32位彩色再敏薯存成bmp，黑白的相对简单，直接bitmap头即可。 如果你要黑白的我可以给你代码~
