  How to colorize a greyscale image using a gradient of colors?
Posted by: wertoiuy - 03-18-2021, 01:28 AM - Forum: General questions - Replies (2)

I have this greyscale image which I made from a layered colored image. The grey ranges from 26/256 to 121/256. I have made a gradient of colors similar to the colored image. I then want to be able to assign one end of the color range to 26/256 and one end to 121/256. Finally I want to take the greyscale image and convert it to color using that specific graduated color range.

I have the gradient made, but I have no clue how to colorize the gray appropriately.

  sample points
Posted by: Pirlouit - 03-17-2021, 12:37 PM - Forum: General questions - Replies (5)

   
Hi,
I just installed Gimp 2.10.22. I am on macOS.
When a photo is imported, the Sample Points window is empty and a message reads (in french): This image has no sample point. However, I checked Display -> Show sampling points. In Picker mode, by installing the guides (vertical / horizontal) on the image, I have the Picker window (pixel / RGB) that opens. But nothing in the Sample Points window. How do I display these sample points? Does it depend on the type of photo (RGB or sRGB, etc.)? Thank you in advance for your advice.

  Icons are very small
Posted by: garnold - 03-16-2021, 12:03 AM - Forum: Linux and other Unixen - Replies (3)

Hello. I've just installed Gimp 2.10 on my laptop. The OS on the laptop is Ubuntu 20.04.2 using Gnome as the desktop. Right now when I run GIMP the icons are painfully small. I have the same issue with a few other applications as well. Most programs work just fine. I installed GIMP via apt. Attached is a screen shot of what I'm seeing. Could I get some help with fixing this please? Thank you!

  Removing alpha channel
Posted by: AncientxFreako - 03-15-2021, 10:43 AM - Forum: Extending the GIMP - Replies (3)

I've recently had some issues with GIMP generating alpha channels after editing images when using layers. Upon exporting to .png, the alphas get left in. I'm being told by an ace programmer that this is a ridiculous thing that GIMP should not do. I really, really like GIMP, and would rather continue using it. Is there an update that deals with this without a plugin?  And btw, I haven't seen a good plugin that even does decent batch alpha removal.

  Wrapping Text Question
Posted by: Jebby - 03-14-2021, 09:15 PM - Forum: General questions - Replies (11)

For some reason there is no POST THREAD button in GIMP 2.10 section. Therefore I posted here.

I can wrap text around a circle using TEXT ALONG PATH tool.  I even know how to make my text taller by turning the text into a path and scaling the path. What I wanna do is take my text, make it taller, then wrap around the circle. After editing the text to make it taller, I cannot seem to figure out how to make the new later wrap around the circle as it is no longer actual text and there is no text to path option.

So how can I make the text taller then wrap on a circle?

  back in time : C=64
Posted by: denzjos - 03-14-2021, 06:04 PM - Forum: Other graphics software - Replies (2)

Some of us have good memories to the commodore 64 computer. It was in his time the most advanced home computer with 16 colors (later more in interlace), good sound (3 tone generators) and hires graphics. If one have a good photo that he want to send back to time of the C=64, then there is a program to convert it to the C=64 color resolution. Save it as prg file after conversion and you can load it in a C=64 emulator or in a real C=64 (if you own one yet). Save it as bmp file for use in gimp.

  How to Copy and Paste a Selection of a Layer
Posted by: BringOutTheGIMP - 03-14-2021, 05:16 AM - Forum: General questions - Replies (11)

Hello!
I've very new to GIMP and need some basic instructions.

I'm trying to clip parts of a layer, which is a page of a book. 
However, when I select the area with rectangle selection tool and use "cut" it cuts the entire layer.

Is there a simple fix?

thank you!

  proof colors vs print plug-in preview
Posted by: ramestica - 03-13-2021, 05:47 PM - Forum: General questions - No Replies

Hi,

the attached image shows the difference I see between the photo that I'm editing, and the preview on the print plug-in.

That in the print preview is much closer to what comes out of the printer.

As shown in the attached screenshot, the color management option 'Proof Colors' is enabled.

How could I make the Edit version look the same as that in the print Preview? 

Thanks,
 Rodrigo
