Select color directly from raster image

morganism3 — Thu, 17 Mar 2022 20:42:37 GMT

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?

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

Hi,

this is offtopic. The topic is "Select color directly from raster image".

Different Question -> another Thread

Start POLYGON or PLINE command!

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:

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

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