I made a plugin to round path corners. (Again I can't help wondering if I am just re-inventing the wheel. But at least it is a new wheel.) The plugin assumes that the path consists of straight line segments. Example: With default input values the plugin did this:

   

To get the plugin, go to

http://kmarkku.arkku.net/Path_modify_fil...aster.html

scroll to the bottom, and click the right download button. You get a zip file. Unzip it and place the one file it contains (round_path_corners.py) in your user's plug-ins folder. Then (re)start Gimp. To use the plugin: in the Paths tab, right-click a path and follow the links Tools > Modify path > Round corners.

I explain a little about the inputs.

The first input is "Where to set arc ends". It offers two choices: the default is "Use fixed distance from vertices", and the other one I skip now entirely. The value for 'distance' is input in the next field. The picture shows the meaning of "distance":

   

(One fact may cause surprises: In the code it is prohibited that the arc ends could go past the midpoints of the corner legs. The purpose is to avoid that two neighbouring arcs might get mixed up with each other.)

The next input allows the user to choose the shape of the arc. The list of the built-in shapes is:

• circular
  
• straight
  
• parabola
  
• close to vertex
  
• through vertex
  
• cusp
  

1. An algorithm to make circular arcs.
   
2. An algorithm customizable with one parameter (this handles all other cases except the circular arcs).
   

Is there a plugin or way to make a B&W photo look like an etching?

This question was inspired by Meetdilip's recent thread about the rubber stamp plugin. Upon trying to create some extra transparent text to add into the results of the output of the rubber stamp plugin, I realized I had no idea how to create transparent text.

I managed to use the Layer Effect-Drop-Shadow filter to create a semi-transparent text addition to the output, but was hoping for fully transparent text effects just as the Rubber Stamp plugin creates.  To illustrate the failure I encountered, a red background was added to the image below.  As can be seen, the text/username "Altie" is not fully transparent.

How can I get Windows 10 File Explorer to show thumbnails of XCF files? I would be happy if gimp's file explorer would show all the thumbnails, instead of just one file at a time.

Hey Gimp Family,

Hope you are all doing well. I am editing a couple of pictures for my instagram portfolio. Whenever I export my pictures to my iphone, the colors and saturation looks different than what is on my desktop. Anyone know what I can do to fix this/make a new color profile?

Thanks

basically I want to do a grid fill similar to this, and I cant find any articles online. any help is appreciated, thanks!


I figured it out. Go to Filters -> Render -> Pattern -> Checkerboard.

I'm using the latest GIMP and the latest GMIC. I'm doing a face swap using a layer mask on one pic. I'm using layer/blend (seamless), input - all visible. It's cutting off a good part of the pic and I can't recover that part by using Image/fit canvas to layer. It's simply chopped off. What can I do to prevent this?

Other time I've used this same preset without this happening. I went ahead and reinstalled GMIC, because at one time earlier today GIMP said the GMIC plugin crashed. This is an old computer 4 gigs of RAM.

Is there any easy method to create a rubber stamp seal other than drawing everything from scratch ? It would be nice if we can customise the text and colour. Thanks.

I am a newbie Gimp 2.10 and I cant see multiple layers together even though i have made all layers visible with the eye icon ? A layer becomes visible over another one when i increase transparency only but this is not what i want... like to see all layers with full opacity..  help !!!

Hello,

I need to "calibrate" digitized images of test prints with the white and black patches of a color card, like the Spydercheckr24 that I have. 
My test prints are alternative photography 256 step wedges, i.e. little squares of degrading tones from the darkest to paper white that I print by hand using an old photographic process.

To better explain my "calibration" needs I can do the parallel with Photoshop. There I open my image containing the test print and the color card at its side (see attached image). I know the Lab (or RGB) values of the patches in my card. Using the Curves command in Photoshop I can customize the pipette values for the white, black and gray points. So I write in the Lab value for the black point and then click on the black patch of the color card in my image. Therefore the black point of the image adapts to the newly customized level. And so I do for the white and gray points inside the Curves command. At the end my image is "calibrated" as per the correct values of luminosity, the darkest and the white colors are as they are supposed to be.

In GIMP I have found that the Levels command has the white and black pipette but unfortunately they seem not to be customizable so they make the white patch to become your white (255,255,255 RGB) and your black patch to become (0,0,0 RGB) and my final test print is out of its real range of tones since the color card has not those values.

My question: is there a way I can perform a color value "calibration" using GIMP as explained above when using Photoshop? 

Thank you in advance for your help!
Paolo

P.S. attached a sample of my scan. I use the gray side of the color card but if of any help (automatic calibration sw) I can use the colored side.
