    This can also be done in TBC under certain circumstances - it is not as simple as it could be but it is totally doable as follows.

     

    The challenge with this in TBC is that many of our "images" are created from a page in a PDF File (that maybe has many pages) and at the time of importing PDF Pages we convert the PDF Pages selected into Images (PNG) and then we optionally tile the image at different resolutions so that as you zoom in and out we regenerate from the image tiles to increase redraw performance. (Support - Options - Images is where you can control what TBC does when it imports images (Tile / No Tile, and Image Downsizing options).

     

    If you actually start with an Image file (JPG, PNG, etc) and insert it (Scale only or Scale and Bearing or georeference it etc), then the Image File is referenced to the project, geolocated and stored in the Project Folder. If you replace that image in the project folder with a new image of the same name and either

    1. Close / reopen the project then the new image will replace the old image (and will if exactly the same scale and location be placed in the right place).
    2. Force the regeneration with the new image file by going to Support - Options - Images and then switch on tile with multiple resolutions or switch to No Tiles (from whichever setting is currently active in your project) and that forces the regeneration with the updated imagery. If you turn on image tiling, then it will regenerate all of the tiles for the different resolutions in this process.

     

     

    We do the Image Replacement automatically if you have the above setting set to "No Tiles" when you close and reopen the project or force the regeneration using the setting switch.

     

    Note that if you started out as a PDF file and extracted e.g. Page 6 then there will be a Page 6 PNG Image in the project Folder and it is that image that you need to replace - you cannot replace a PDF file and have it re - extract page 6 automatically because it changed - so you may need to start a new project and create the images from the updated PDF file before using them as replacements in your working project. I would also be very wary of doing this as any slight shift in the Page Layout by the designer, or a change in scale of any kind will throw off the project data in TBC.

     

    Hope that this helps / answers the question
