[FEATURE REQUEST] Selectable aspect ratio

[mamalala]

Is your feature request related to a problem?

Currently the layer view maps the pixels in the layer to the pixels on screen 1:1.
This is just fine if the printer's pixels are square (like the Creality LD006, which is used until recently). However, for printers with non-square pixels, for example the Creality Halot Mage S (which is what i use now), the actual view is distorted. That is, for example, a circle in the model becomes an ellipse.

It would be a nice option if there is a checkbox in the/around the layer view that lets you select either a 1:1 pixel mapping (useful for the pixel editor) or to have a aspect-reatio correct layer view. Of course this depends on wether the loaded file contains the needed information, like the .cxdlpv4 format. It contains the print bed size in mm, as well as the pixel resolution per axis. If the file format does not contain such information, it could be configurable parameters.

It seems that with printers using a 14k resolution that they all do not have square pixels.

Describe the solution you'd like

Have a checkbox in the main window that toggles between a view with 1:1 pixel mapping and a view that takes the aspect ratio of the printer's pixel size into account.

If the loaded file contains the required information (print bed size X and Y in mm, and the screen resolution in X and Y), that should be used as default.

If the file format does not contain such information, these parameters should be configurable.

Also debated here:

• Rectangle pixels are only square in UVTools? Can it be changed to rectangles? #866
• UVtools window stretched or not in correct aspect ratio #908
• Pixel editing aspect ratio matching printer pixel sizes #913

Most likely won't be implemented. The huge impact, code modifications and translations to make this work is just too big for just a visual aids, UVtools is already slow with resolutions going up, adding something like this will make it worse.
The simple approach is resize to compensate the ratio but that would only enable a view-only of current layer as the modifications must be done on the original bitmap, as so tools could run, but not the pixel editor nor ROI or the mask selection tool. Resize and resize back to "original" state is also no viable option as some pixels would be lost in the conversion due the fractions, invalidating the original model.
I will have a look into the render but I suspect none of this is possible without major modifications and the read-only preview is the best I could do for now.

If anyone have an ideia or a working concept I'm open to it.

Hello,

understood. And i agree that this is purely a visual/display thing, and as such has a very low, if any, priority. Unfortunately i have no clue about C#, i only do C and C++, otherwise i could possibly contribute myself.

Thanks for your reply anyways, and for thinking about it. As such, you can then close the request if you want.

Greetings,

Chris
