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

I always have "problems" with the coyote humor. It's hard for me... I
prefer other kinds of humor, like frog's humor or rabbit's humor but
it's all ok, it helps me to get good answers to my strange questions.
Cheers,
nata

Nice sense of humor but the "partial" solution works on WINDOWS, MAC
and LINUX so I don't see the problem. I know that we have to be treat
the paths carefully in IDL but I was just talking about the bmp paths
for a widget_button.
Thanks for your help anyway teacher :)

I was trying to gently prod you toward the general solution,
rather than the partial solution you have here. They say
the teacher appears when the student is ready. I don't know
what happens when the teacher appears *before* the student
is ready. He probably loses his IEPA card. :-(
Cheers,
David

Well, on your machine and machines like it, I guess. :-)

Normally, I use paths like: button_file = './resources/
mybuttonfile.bmp'
And always works fine.
I was just testing some created bmp files.

Well, neither do I. I use paths like this:
buttonFile = Filepath(RootDir=ProgramRootDir(), $
SubDirectory='resources', 'mybuttonfile.bmp')

Well, then, I would try an absolute path name to the
file instead of a relative path name.
