User-defined Global scale for Import Bitmap?

Post by DerekGove » Wed Jul 26, 2023 1:17 pm

Hi all,

I'm currently using QCAD to produce specification sheets for work, and this includes orthographic and an isometric images rendered from a 3D package.
I render them at 10 pixels per mm, and they need to be printed at actual size.

When an image is imported with 'Import Bitmap', it defaults to 1 pixel to 1mm. This is a sensible and understandable setting. But for each of my images, I have to click in the Width or Height field in the toolbar, and insert a decimal point before the last digit to rescale it.

Whilst this isn't a massive workflow issue, it would really streamline things if I could tell QCAd in the preferences that (for example) all my imported bitmaps should be scaled to 10 pixels per mm.

Cheers,
Derek

Derek,

This is not implemented, by default it is 1 pixel per drawing unit.
Maybe you can play with the actual drawing unit and the convert between units.

Still, the single addition of a decimal point is by far the easiest method.
The tool could include a Scale factor and save that persistent like most other tool options.

For such a request it would be better to open a feature request at Bugtracker:
https://qcad.org/bugtracker/

You need a separate account there or make a new one.
