It looks like Classify only works for Grayscale images, not color images.

As far as I can tell, there isn't an easy way to convert a color image to grayscale in Pro. There appears to be a raster function for converting an image to grayscale, but it doesn't seem to do what I want, at least not as easily as I would like. Convert color image to grayscale It would be great to have a simple geoprocessing for converting a color image to grayscale, for the purpose of classifying the image: Easily remove white pixels from georeferenced plan. Raster Symbology — Automatically convert color raster to grayscale to support Classify primary symbology

ArcGIS Pro 2.9.5 and 3.4.0 I have a sample plan & profile image: https://epg.modot.org/files/9/94/237.4_Plan-Profile_Sheet_Oct_2011.jpg I want to convert the color image to grayscale. Use case: Easily remove white pixels from georeferenced plan Why is Primary Symbology > Classify unavailable for some images? I tried this: Imagery ribbon tab > Raster Functions > Raster Functions > System > Conversion > Grayscale > Create new layer Error: Failed to apply Grayscale I also tried Colormap to RGB, since that was recommended in a few forum posts. Error: Failed to apply Colormap to RGB. Why am I getting those errors? How can I convert a color image to grayscale in Pro?

ArcGIS Pro 3.4.0 If I add a slow item (drag-and-drop or "Add to current map") from the Catalog pane to the map, such as a georeferenced image, then it takes 30 seconds for anything to happen in the map. I often wonder if Pro is doing anything. Is it adding the image to the map? Or did my drag-and-drop not work, and I should try again? As far as I can tell, there's no indication that Pro is thinking in the background in this scenario. The mouse pointer doesn't change, and there is no progress bar or progress icon in Pro showing that the image is loading. Could that be changed so that we know when Catalog is thinking?

Edit: @CharlesGrant's Classify option worked too. Just make a new dynamic greyscale layer using Raster Functions, since Classify only seems to work with greyscale. Why is Primary Symbology > Classify unavailable for some images?

Thanks @RichardHowe. Issues (Pro 3.4.0): An image I extracted from a PDF as a .TIFF using Adobe Acrobat only shows up as a white blob in Pro. I solved it by exporting the image to a JPEG in Microsoft Paint, and that worked better in Pro; I could see the image. I georeferenced the JPEG and saved the georeferencing. But when I closed the georeferencing, the georeferencing information was lost -- the image was no longer georeferenced. I did the georeferencing again to the same image, saved, closed, and it worked that time. Related: Georeferencing bugs in ArcGIS Pro With the JPEG, I don't see the Primary Symbology > Classify option mentioned in Easily remove white pixels from georeferenced plan. ArcGIS Pro crashed my computer spectacularly when using the georeferenced JPEG in a map. My computer 100% froze, including the mouse not even moving on the screen. When I use the JPEG in my map, it only is visible for a short while, then the black pixels disappear after I've moved around in the map a bit. The white envelope/blob still remains. I need to turn the layer off and on again in order to see the black pixels in the image. I can't seem to export the georeferenced JPEG to any other format properly, such as TIFF or FGDB. The resulting images are either a white blob or a black blob. Now that Pro 3.4.2 has been released what issues do people still have that are not yet addressed?

ArcGIS Pro 3.4.0 My experience is that georeferencing is buggy in Pro. What file type is the most stable? TIFF? FGDB? Something else?

Generate Definition Query From Selection A definition query clause has a limit of 1,000 values. If the selection includes more than 1,000 values, the resulting definition query will include multiple clauses. I understand that 1,000 values in the IN clause is a lot (and unconventional in terms to SQL best practices). I understand why there might be a limit. Buy why 1,000? Is it based on a known database limitation for certain kinds of DBs?

Geoprocessing tools have names like: Create Database View Make Query Layer Generate Definition Query From Selection What's the reason for using Create vs. Make. vs. Generate? Does the word usage indicate the type of object that's created? Such as a persistent object, a temporary object, or a calculated list/records?

I have multiple definition queries for a given layer. I want to document the SQL definitions of all the definition queries. As far as I can tell, I would need to go into each definition query, switch to SQL mode, and copy/paste the SQL into my document. It would be more efficient if there were a button to copy the SQL of all definition queries to the clipboard in a single action.

I have a comment in an idea that I want to delete: https://community.esri.com/t5/arcgis-pro-ideas/symbology-lacks-the-options-for-turn-on-or-off/idc-p/1571466/highlight/true#M33374 I used to be able to delete my comments from ideas. But the delete button seems to be missing. Why was the delete option removed from the Post Options menu?
