All,

Im trying to select with the magic select tool.  When I initially click I get the outline of the selection but as soon as I let go of the mouse button the selection goes away.  I do have show selection on under view, Im on replace selection for options of tool, my threshold is 15%.  Im at a loss.  Any help is appreciated.  I even reinstalled GIMP.  Im running 2.10.14


Cant figure out how to add an attachment.....

Hello all,

Are there any ways to manage adding or removing multiple layers in a Layer Group?

Something like moving linked layers, or visible layers or whatever?

There is the Multiple Layer Actions script, but it does not perform this task.

I always have to do this one by one.

Thanks!

Hi all, I have a question about alpha channels. When I click the eye icon next to the alpha channel of a layer to hide it, then export it to PNG, the exported image still has the alpha channel. However, removing the alpha channel entirely produces a different, unwanted result, turning the image blue-ish. This blueness is kept when exported.

Is there any way I can export my image to a PNG so that it looks like it does in GIMP with a hidden alpha channel?

Thanks!

I have a significant number of jpegs that require editing.

I prefer to save my edits as png doing the following:
(1) Shift+Ctrl+E
(2) Alt+T for Select File Type (By Extension)
(3) mouse click on "By Extension"
(4) Type "png" press Enter
(5) Alt+E for Export
(6) Alt+E for Export
As you can see, I use keyboard shortcuts and do so rapidly. However, for such a large volume of jpegs, this becomes time-consuming and laborious.

Is there any way to automate this process? Grateful to hear if there is a way to do so.

Many thanks

Can anyone tell me how to remove the dark splotches in the background of this image. Some of these dark splotches are up against the hair of the monkey. Is there a way to mask the monkey using Edge Detect, and if so what are the steps?

Hello,

Is there any GIMP tool or plugin that can be used to separate an image into groups with the same color?

This is what I'd like to achieve:



I created the layers using the fuzzy selection tool and pasting the selection as a new layer. I'd like to do something like this but with one click... like when using Filter > Enhance > Wavelet-Decompose or Colors > Components > Decompose.

Thank you!

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?
