> According to the documentation (http://www.exelisvis.com/docs/read_BMP.html), READ_BMP does not handle 1-bit-images or compressed images. You can examine the file with QUERY_BMP before you try to read it and find out if it is one that READ_BMP likes.

Thank you, Mats

I got another question here. When I use the read_jpeg or read_bmp function to read the picture, all information is saved in the variable. But when I try to use TV,variable to display again, it shows me a black screen

IDL> read_jpeg, '1.jpg',a
IDL> tv,a
