Lisp function to Insert image via drag and drop into Bricscad drawing

Edward Winter

 In AutoCAD when you drag and drop an image into the drawing a lisp function will be triggered named ImageFile.

I can change this routine to my own needs.

How does Bricscad handles drag and drop images into the drawing? Can I change it to my own needs?

Roy Klein Gebbinck

If you drag and drop an image file the _IMAGEATTACH command is called. Redefining that command should be possible.

Roy Klein Gebbinck

Scratch that. It is not going to work.
The command is called as:
(COMMAND "._IMAGEATTACH" ...)
Meaning the un-redefined command is always used.

I believe the command should be called as:
(COMMAND "_IMAGEATTACH" ...)

But somehow there must be a Lisp function at work here... I can't find the file though.

Edward Winter

AutoCAD defines the ImageFile routine in the acaddoc.lsp or acadxxxxdoc.lsp, which loads with every drawing it loads. 

So is there a similar doc.lsp used with Bricscad?

Roy Klein Gebbinck

BricsCAD supports start up Lisp files. The file names are on_doc_load.lsp and on_start.lsp. But these files are not part of the default installation.

Is there any way to include IMAGEATTACH in a lisp routine and force it to use the dialog box?
If I type the command name I always get the dialog box.
But when I include it in a (COMMAND) function I always get a command line prompt for "Image name: "
I've tried it with and without prefixes,and with various settings for FILEDIA and CMDDIA.

Roy Klein Gebbinck

With other commands using the initdia function does the trick, but not with IMAGEATTACH.
I suggest you use the getfiled function.

Roy Klein Gebbinck

Oops... Anthony, scratch my suggestion regarding the use of getfiled. This is not just about selecting the file, you want the full 'Attach Raster Image' dialog.
