[sane-devel] Basic Image Buffering

[dio.rahman at gmail.com]

Dear all,

I have a basic question on buffering the image.

Suppose I have an image data pointer * imageData; and I have image
dimension information i.e. width and height.

I need to copy the bytes read from the scanning process i.e. in the
buffer (sane_read(buffer,buffer_size,&len)) to the image data.

So, I do:

for(int i=0;i<len;i++)
    *(imageData++) = buffer[i]
until I found the SANE_STATUS_EOF

but, when I showed the image, the pixel is not in the right order;
Anyone can help me?

Thanks

Dio
NOTE: I'm using CanonScan LiDE 50 -- grayscale image; and doing find
with the scanimage example
