Hi guys,

Widget_buttons only accept bmp images so if I want a button with a jpg
image (for example) I've to convert it to BMP. I try to do that and my
final BMP has the following definition:

image=read_bmp('import.bmp', r, g, b)
help, image, r, g, b
IMAGE BYTE = Array[16, 16]
R BYTE = Array[256]
G BYTE = Array[256]
B BYTE = Array[256]

test=QUERY_BMP('import.bmp', info)

help, info, /str
** Structure <da333dc>, 7 tags, length=40, data length=36, refs=1:
CHANNELS LONG 1
DIMENSIONS LONG Array[2]
HAS_PALETTE INT 1
NUM_IMAGES LONG 1
IMAGE_INDEX LONG 0
PIXEL_TYPE INT 1
TYPE STRING 'BMP'

All of that seems ok but when I try to create the button I've an
error:
% WIDGET_BUTTON: Can't open bitmap file: import.bmp

I don't know why this errors happen. When I try to open original BMP
files that has the same definition, the button can be created so I'm
very confused.

Does somebode help me?

Regards,
nata
