Inverted colours over attached images

I’ve just started the switch from AutoCAD to BricsCAD and come across a feature I would like to turn off. If I have attached an underlying white image, when working with text and linework (ie moving them) on top of the image their colours are inverted during the move. Red text becomes cyan and difficult to see on top of the image. Is there a way to turn off this inverting?

Comments

  • Are you using "draw order" or Move ie a different Z.

  • I'm using the move command.

  • Understand now Its a programming thing just has that color programmed in. Maybe do a support request.

  • It is even worse, the crosshair becomes completely invisible when working with topographies, aerial photos, due to pixel colour inversion.

    See attached bitmap, find the cursor, to go crazy.

    I reported this as a bug via a support request ages ago but if only one person complains then of course nothing happens. As a result, you have no notion where your cursor is.

    What you can do, but it's all stopgap, is the following:

    • Work with a cursor at 100% (‘cursorsize’ ‘100’)
    • Change properties of bitmaps via properties (‘fade’, but that creates new problems)
    • Make sure the ‘aperture box’ is visible (“apbox” ‘1’).

    In conclusion, there is no proper solution (as far as I know).

  • In addition:

    It concerns support request SR149430, ‘crosshair visibility’.

    The status is: ‘Closed (Feature request)’.

    So nobody finds it interesting enough to fix it, it is apparently seen as a feature request and not a bug.

    For some people it is the reason to prefer AutoCAD, which does not have this problem.

    If people from Bricsys read this: Please open the case again, this is not a "feature request", it is a "straight bug" that makes working with BricsCAD impossible.

  • Agree! The bug interferes with the use of 3rd party tools like Autopath that make heavy use of background images. Doesn't occur with AutoCAD.

    A partial workaround is to switch from the 2D draughting visual style to a rendering one, such as modeling. The down side to this is that draworder isn't respected in rendered visual styles.

  • In V25 CURSORMODE variable has been introduced, it enables to switch between XOR and Non-XOR modes for the cursor. When it's ON, cursor keeps colors over images.

  • EXCELLENT NEWS!!!

    Thank you so much! This was a major argument for not using BricsCAD for users and the screen dump above illustrates the conundrum very well. I must have missed a release note.

  • Thanks for everyones comments. I submitted a support request and it has been sent to the development team to further investigate.

  • I don't understand, SamG, did you get the message from Lyubov Osina? Go to settings⏎, search for CURSORMODE or enter it straight on the command line: CURSORMODE⏎.

  • Unfortunately, CURSORMODE works for cursor crosshairs only, not for other entities.

  • Thanks Lyubov Osina, now I understand. SamG, sorry for the confusion. Summarized:

    Good news: XOR of crosshair can be turned off.: https://help.bricsys.com/en-us/document/system-variable-reference/c/cursormode-system-variable?version=V25&id=171990422511

    "Controls how the crosshair is displayed."… "On (1): Displays the crosshair in Non-XOR mode."

    Bad news: Dragmode misses a bitsum for turning off XOR and the result is this:
