americanpaddy Posted May 26, 2022 Share Posted May 26, 2022 I work on line drawings of airplanes. Profiles mostly and it seems that when I re-open a file I discover changes made and saved do not appear. In fact I have to re-do an area that was painted no longer has the latest effect. I'm not doing anything fancy or complex - best example: within an area I put in two new lines, save and close. When I re-open the drawing, that change is not there. Or, another example: I open a drawing and there are shadow pixels in an area I painted, saved and closed. All files are saved as PNG. In the attachment the lines were being changed from black to gray......... all the changes were made.... when I reopened the file the lines were mostly black.

Pixey Posted May 26, 2022 Share Posted May 26, 2022 Hello @americanpaddy and welcome Perhaps try doing the line drawing on a larger scale and see if this helps. 1 Quote How I made Jennifer & Halle in Paint.net My Gallery | My Deviant Art "Rescuing one animal may not change the world, but for that animal their world is changed forever!" anon.

IHaveNoName Posted May 26, 2022 Share Posted May 26, 2022 If you're using a lot of layers are you saving your WIP (Work In Progress) as PDN or just PNG? I've found it is all too easy to forget you've stopped a particular layer displaying for whatever reason (typically before and after comparisons) and when you flatten the image you don't notice and save it in that state. I save WIP projects in both PDN and PNG or other preferred format for precisely this reason. Too often I've come back to the PNG and realised its missing something you know you did. You go back to the PDN file and realise the missing detail was indeed in a non-displaying layer. It happens. 2 Quote Link to comment Share on other sites More sharing options...
