Hello,

Why is it that raw data export always contains alpha channel if the image has more than one layer?

I have image in RGB mode with multiple layers and would like to export each layer as individual raw data file containing only RGB data (i.e. 3 bytes per pixel).
But I cannot get the file exported without alpha channel being saved as well (4 bytes/pixel). I have made sure alpha does not exist in any of the layers (selecting "Remove Alpha Channel" on all layers). If I delete all but the layer I want to export, it is exported without alpha like I want.

I am working around this now by copying and pasting each layer to a new image, removing the alpha channel from that, and exporting the new image to raw file.
Even that would be quick to do if all steps had key shortcuts, but the alpha channel removal must be done with mouse still which slows down the process (select layer, Ctrl-A, Ctrl-C, Shift-Ctrl-V, remove alpha with mouse, and finally Ctrl-E).

Is there some setting somewhere that says multi layer images always contain alpha channel, even if individual layers do not?

Thanks in advance,
Tomi

I've been using GIMP for many years and have never had a problem such as this. I did some minor edits in a JPG image. I then export it as a JPG. Now windows doesn't seem to recognize the image. The thumbnails come up with a default image icon and when I try to open the JPG in Microsoft Photo, I get an error message "It looks like we don't support this file format." No other windows software seems to be able to open it but GIMP has no problem opening the image. I have tried renaming it file and saving it with a different name with no change in outcome.
I'm running Windows 10 v.20H2 and GIMP 2.10.22

I am having trouble with GIMP text tool. Here is the info:
Version GIMP 2.8
OS Linux Mint
Problem: Unable to resize text. I:
1. Open GIMP
2. Create new image 12 X 16 inches with transparent background
3. Open text tool
4. Either copy / paste or type text into image
5. No problem changing font, etc
6. Attempts to change text size either on on image dialog box or on the tool bar have no effect. The changes in one place do not make a corresponding change in the other. The text size remains at the eye popping poster size of 16 pixels! (or corresponding size in other measures) Fortunately GIMP allows me to zoom in on the text so I can verify that it is actually there. It is.
I must be missing something.(That is why I provided a detailed step by step.) Any suggestions?

Hi, first time caller - so go easy on me.

I'm running GIMP 2.10.18 on Win7, trying to run a script from the command line using:

Hi, new to the forum,
Just tried to reopen a file on mac and 1 of the layers had completely disappeared. Is this a common issue? Any ideas? I've tried file recovery, checking layer groups and can't for the life of me figure this out.
Thanks!

 Hello everyone! 
I thought id be nice enough to introduce myself here, as I'm hoping to become a permanent resident on this forum.
My name is Dot, I'm from the Netherlands, from Groningen to be precise,!
like most women my age, I will refrain to enlighten you about mine for now 
have a wild guess id say    
 I first got to know of GIMP via SecondLife (yes it's still a thing)   lol 
Where I use gimp to make textures for products I create. 
I'm a creative bit of a weirdo 

at this moment I'm busy creating a personal website, I have had many sites over the years, but this is my 1st time actually paying for a propper domain and actually devoting my time to this! the site is about women with autism, and mostly about me, as everyone is different of course.
sofar I'm loving it! though here and there I'm running into small hurdles xD  
and I'm sure I could benefit greatly being a member here, 
love the look of this forum, not too huge to not find bank whats going on 

See you on the forum! 
Feel free to ask me anything, my life is an open book

Hello everyone

I have a bit of a complicated question 
Im creating a website and on it i want to have a GIF that explains some things
As im creating it im noticing that im using a lot of imgs ..
before I continue .. id like to know if there is a limit to howlong a GIF can be 
Can a GIF be too big/long that it simply will stop working ? 

(if its okay id like to keep this thread open, as I might have more questions as time goes on
im autistic and i easily get lost in on a forum.)

Bonjour tout le monde, nouveau sur vaste et riche forum je n'ai su retrouver ce sujet.

Je suis novice en informatique    d'où il faudra m'expliquer les manipulations pas à pas de plus je connais pas le logiciel GIMP mais j'ai acheté bouquin pour les débutants.

Une bonne âme pourrait-elle voler à mon secoure ?

I am new and just downloaded Gimp.  When I greyscale a photo then Filters, Distort, Newsprint I do not get the options to come up.  It simply converts to the newsprint so I'm not able to set resolution, etc.  I can't seem to find how to turn the options feature on.  Hope someone can help me.  Thanks much.
