.png Files Support in Aftershot 3 Pro

Post by rjbcollege »

Is there any danger of Aftershot 3 Pro ever supporting png files?
I use Aftershot 3 Pro for my raw files but have to export as either .tif - for those with infinite hard drive space, or jpg with all the quality loss that entails.
Moreover, I cannot use Aftershot 3 Pro on existing .png files without first converting them to another format and losing quality in the process.

It is 2021 as I write this, .png files continue to replace jpg on the web and some of us want to be able to export as this and some of the starting points are therefore in .png format already. To convert these to .tif first is already losing speed, quality (in the process, not in the end format) and gaining file size. Converting first to jpg also loses quality and can, depending on settings used, also increase file size as well.

Come on Corel, catch up, please!

I cannot help you for .png as input (ASP is a raw converter - cameras usually create raw or jpg files).
But you can use simple scripts to export to .png

This is suggested by the book AfterShotSurvivalGuide (not available any more):

"Generating PNGs:

AfterShot 5 does not support generating PNG files. It is quite easy
to use the ImageMagick convert command to convert images.
However, we cannot use this command directly, as we also need
to change the filename to reflect the changed file type. Therefore,
shell scripts are used as a front-end to the actual processing command.
For Windows, we use genpng.bat. For Mac OS and Linux, we
use genpng.sh:
@echo off
"C:\Programs\ImageMagick\convert.exe" "%1" "%~p1\%~n1.png"
del "%1"
/usr/bin/convert "$1" "${1%%.tif}.png"
rm "$1"
These scripts assume a TIFF queue for generation of the intermediate
file. We need to create filename.png from filename.tif, which is
handled differently on Windows than on Mac OS and Linux, resulting
in the need for two different scripts. The last part of the convert
command-line in each of the scripts performs the required substitution
of the file extension. The path names to the convert command
might not be identical on your system.
The logic used here can be used for much more complex scripts
that add watermarks or borders or to generate captions.
Before you integrate any command or script into a queue, run it on the
command line to ensure that it works as anticipated.

another way (example for linux - but nconvert is available for win too):
/usr/bin/n convert -out png -q 93 -opthuff -resize 640 640 -ratio -rflag orient -rtype lanczos %1"

I am on linux - but it should work on WIN as described above...

Maybe this helps ...
