Select color directly from raster image

[morganism3]

Hello, I needed to know how to click on something in a raster image and "pick up" that color... What in other programs is called a "dropper" tool. I know AutoCAD has the capability, but all the help files direct me to a specific section under Raster tools that doesn't appear on my ribbon (despite having AutoCAD 2021), and it doesn't list a keyboard command. Preferably I'd just like a keyboard command for this.

AutoCAD alone does not have that for raster images. Sorry.

Raster Design is an add-on you get from your accounts manager then install deliberately/on purpose, it doesn't happen on its own https://www.autodesk.com/products/autocad/included-toolsets/autocad-raster-design

What do you plan to do with the 'Dropper' tool? 

[dany_rochefort · Accepted solution]

You have to do it manually, getting the RGB info from MS Paint or Paint.Net, then input that back into autocad.

Some raster image files need to be converted to a different file format before you can assign them an AutoCAD® color.

If the raster image is not bitonal or 1-bit, then you need to convert it. Follow these steps: 

1. Open the image with Microsoft® Paint.
2. Click Image menu > Attributes.
3. In the Attributes dialog box, click Black and White.
4. Click OK to close the dialog box.
5. Click File menu > Save As.
6. In the Save As dialog box, select TIFF (*.TIF,*.TIFF) from the Save as Type drop-down list.
7. Click Save.

Now, you can insert the image into AutoCAD (using the _IMAGEATTACH command) and assign it a color.
