Question on image size. #99

Closed WirthmU closed 2 years ago

WirthmU commented 2 years ago

I am using a RPiQH camera. I have the following settings on my allsky config.sh which should allow for the size of my pictures:

IMG_RESIZE="true"
IMG_WIDTH=4056
IMG_HEIGHT=3040

CROP_IMAGE="false"

AUTO_STRETCH="true"
AUTO_STRETCH_AMOUNT=90
AUTO_STRETCH_MID_POINT="90%"

RESIZE_UPLOADS="true"
RESIZE_UPLOADS_SIZE="960x720"

Now the current liveview picture looks perfectly fine and I do get the whole picture. 31-03-_2022_12-49-36

However the startrails are looking way too big: 31-03-_2022_12-50-54

Where would I need to adjust for the startrails so they are not so big?

EricClaeys commented 2 years ago

@WirthmU. First, I suggest setting IMG_RESIZE to false. All it's doing right now is resizing it to the same size, which only decreases quality slightly. What is the 2nd picture? A full startrails image, or only the upper left portion? Normally in startrails pictures the date and time are a combination of all the images so are unreadable.

WirthmU commented 2 years ago

IMG_RESIZSE does not change anything in the appearance of the picture on my website http://80.219.133.218/Bern/allskyB.htm.

The second picture is what appears if I do select "archived startrails" from the live view screen and then any of the archived startrails pictures. In this particular case it does not show the combination because the weather is bad so there is only one picture.

EricClaeys commented 2 years ago

@WirthmU I didn't expect turning off IMG_RESIZE to change the picture, although if you look closely you may see the quality is better. It saves a little time and another write to the SD card.

The large text started appearing March 15 when it appears like you upgraded the software. The images before that are fine. Would you please attach your config/config.sh file?

It's interesting that the thumbnails for the startrails are fine. If you open the startrails images while on your Pi are they OK? They are in /var/www/html/allsky/startrails.

WirthmU commented 2 years ago

Yes - you are right - the change appeared after the update anywhere between March 10 and 15.

My config.sh looks like as follows:

#!/bin/bash

# NOTES:
#  - Variable names must start at the beginning of a line.
#  - There should be nothing after a variable's value, i.e., no comments on the same line.
#  - Values can optionally be quoted with double quotes, NOT single quotes.
#  - If a variable occurs multiple times, only the last value is used.

# Choose between "ZWO" or "RPiHQ".

And yes - the startrails on the Pi and also in the AllSky administration file are ok:

@WirthmU I don't think this is an Allsky issue; I believe it's in the changes you made, or related to the
