#146 Keyword parameter GET_DECOMPOSED is not allowed in the DEVICE procedure

[uborka]

Hi All,

first of all, thanks for your hard work making GDL more and more feature rich. However, lately I found a missing feature, without which I cannot use many of my IDL programs in GDL (e.g. which are using the Coyote library). The following command gives the following error (typed in just after start and reproducible both in the Workbench or at the command line):

GDL> DEVICE, GET_DECOMPOSED=decomposed
% DEVICE: Keyword GET_DECOMPOSED not allowed for call to: DEVICE
% Execution halted at: $MAIN$

It is weird, that using the #device command prints the following in GDL:
GDL> #device
Internal PROCEDURE : DEVICE,CLOSE_FILE,FILENAME,LANDSCAPE,PORTRAIT,DECOMPOSED,GET_DECOMPOSED,Z_BUFFERING,SET_RESOLUTION,SET_CHARACTER_SIZE,XSIZE,YSIZE,COLOR,GET_PAGE_SIZE,GET_SCREEN_SIZE,INCHES,WINDOW_STATE,SCALE_FACTOR,XOFFSET,YOFFSET,ENCAPSULATED,GET_GRAPHICS_FUNCTION,SET_GRAPHICS_FUNCTION,CURSOR_STANDARD,CURSOR_ORIGINAL,CURSOR_CROSSHAIR,RETAIN,BITS_PER_PIXEL,GET_WINDOW_POSITION,GET_PIXEL_DEPTH,GET_VISUAL_DEPTH,GET_VISUAL_NAME,GET_WRITE_MASK,COPY

For me, this means, that there IS a GET_DECOMPOSED keyword implemented, but somehow it is not working as I would expect. What could be the problem?

However, running the same command in IDL (version 8.4) gives the following result:

IDL> DEVICE,GET_DECOMPOSED=decomposed
IDL> print,decomposed
1

It seems to me, that the feature set of the DEVICE procedure is unchanged since version 6.1. Could you please add this feature?

Thanks for your help!

Best regards,
uborka

Sorry, I forgot to mention, that I use Windows 10, 64 bit operating system.

[Alain C.]

excuse me, which version of GDL do you use ?

GDL> print, !gdl
{ 0.9.6 CVS Aug 2 2016 1470088800}

because GET_DECOMPOSED is implemented since a while !

(might be good to try a CVS version in a Linux Virtual Machine
in your MSwin OS ?)

[GregJung]

I can confirm this behavior in the CVS build for windows. Its OK in my own version which is only a little modified w.r.t. the relevant routines.

[uborka]

I have the released 0.9.6 Windows build.

GDL> print,!gdl
{

0.9.6

Jan 5 2016
1451948400
}

Can you link a tutorial on how to build the CVS version for windows? I would give it a try. :)

EDIT: I also checked the situation on Linux, and it seems, that this is a Windows issue, since device,GET_DECOMPOSED=decomposed works on Linux even with the 0.9.4 release (which is the standard repo release right now for Ubuntu 14.04):

GDL> device,GET_DECOMPOSED=decomposed
GDL> print,decomposed
1
GDL> print,!gdl
{ 0.9.4 Mar 6 2014 1394060400}

Hey Guys,

any update on this? Please, tell me there are some good news!

Cheers!

Greg, Jeongbin, could you please provide us with an update on this issue (as it seems Windows-only)? Thanks!

[giloo]

should be OK as window's devices (win, wxWidgets) are of class GraphicsMultiDevice wich implements GetDecomposed()

[GregJung]

If the "legacy" drivers are deployed, the same issue arises in the git
version. For the new scheme,
when the environment GDL_USE_WX is set to "yes", then wx is in charge of
the plotting and get_decomposed
keyword works.

If we wish, I have a set of routines that can be used to implement this in
legacy gdlwinsream.
