The probable solution to publishing to image (JPG, PNG)

Hi!

After years of lurking, I finally registered here because I think I have a useful contribution.

I was required to do a presentation using project drawings and since google slides doesn't accept PDFs, I had to publish the layouts to .jpg or .png. Screenshots are a bad solution, I was tired of having to export pdfs and converting them to .jpg, I wanted a direct publication from archicad to the google drive folder I was using, and being able to update drawings as needed, a clean, direct workflow

Most people's .jpgs turn out fuzzy and low res, but I found out how to publish with good quality. I don't know much else, why it works, what's behind the scenes in archicad, I just know it worked for me.

I created a publishing set with my layouts and just before hitting publish, I zoomed at 100% in the current layout. That's it. The resolution output is determined by the current zoom you have when you hit publish.

I hope this is helpfull to whoever uses .jpgs, I found the solution myself and then searched the forum again for the word "zoom" and found an answer deep in another old thread.

hope it helps!

p.s. sorry for my english, not my first language

Confirmed that the actual Layout Zoom (100%, 200%) at the time of Publishing affects file size.

I did a series of tests. I have published a Layout to PNG five times.

First, I set the zoom of the Layout to 100% before publishing. The resulting PNG file was 3160x1946
When I set the zoom to 50% (half of 100%), the resulting PNG file was 1580x973 (half of the size of the 100% image)
When I set the zoom to 20% (1/5th of 100%), the resulting PNG file was 632x389 (1/5th the size of the 100% image)
When I set the zoom to 200% (2x the 100%), the resulting PNG file was 4000x2464 (less than 2x the size of the 100% image). I think, here I collided with a limitation, Archicad does not seem to save a PNG larger than 4000 pixels in either direction.
When I set the zoom to 500% (5x the 100%), the resulting PNG file was again 4000x2464. This confirmed that 4000 pixels is indeed the limit of the published image size, at least in the case of PNG.

I have then tested all other image formats (BMP, GIF, JPG, TIFF) and 4000 pixels was always the largest image I could achieve.
