how come that ZWcad still can't import georeferenced raster images? I have several rasters with "world files" and ZWcad only gives me the option to place and scale them myself (which is, of course, not an option).
I thought that was fixed a long time ago :S
Is there any plugin or addon that enables that?
EDIT: I found GeoRefImg by CADstudio, a VLX LISP
It's listed as freeware, and works well on Zwcad+ :)

I downloaded the latest georefimg vlx file from the website provided by thread starter http://www.cadstudio.cz/georefimg & tried to use it on ZWCAD+ 2015. I am receiving the error as per below image.
Incompatible CAD software
As per the comments, some of the users manage to run it successfully(although it was run on a previous version of ZWCAD+)
I am not sure what might have caused me getting the "Incompatible CAD software" error.
Can anybody assist or shed some light on what might have changed with the VLX file compare to the old one? How do I get it to work with ZWCAD+ 2015?

Zwcad had this feature in version 2012, but it give's false result, or better, wrong result. This is the reason that this feature was dropped out in all other versions. By the definition, world file have 5 or 6 parameters, one of them is insertion point of raster file. After inserting raster image with world file, insertion point of raster is not insertion point, middle point of first pixel must be insertion point. No matter how small the amount was or is (half of pixel, depends on size of pixel, resolution of raster image) it was not correct!
sampleFile.tfw (from ESRI World File Format)
5.000000000000 (size of pixel in x direction)
0.000000000000 (rotation term for row)
0.000000000000 (rotation term for column)
-5.000000000000 (size of pixel in y direction)
492169.690845528910 (x coordinate of centre of upper left pixel in map units)
5426523.318065105000 (y coordinate of centre of upper left pixel in map units)
(btw, check bold label text in editor )
Hm, where is bold/blod picture?
Click the image to insert? I upload that picture!

I found in Zwcad 2015 (2015.05.26(27086)), Image Attach and Use positioning file. I don't have Autocad Raster Design at home, it will wait till Monday (Cadastral maps, M 1 : 1000, 750 * 500 mm, grid 100 mm, calibrated with Microstation Descartes, and exported as world file, all grid points are in less 0.2 mm)
