Hello,

I work with photogrammetry, am interested to experiment with using separate processes of RAW, the conventional for projecting color to the model and outputting texture maps, the other for scene reconstruction itself. I'm unsure how any SfM engine will deal with an image that hasn't been demosaic'd (or deBayered), but what I stand to gain in improved resolution of the geometry is worth investigating. Can anyone suggest how this might be made to work? Simply the RAW data saved to 16-bit TIFF holds promise. I could then apply sharpening, though I'm unsure if sharpening won't like the Bayer pattern of 2 green pixels for every one red and one blue pixel. I'm reading about pan-sharpening, which accomplishes exactly that, but is part of a commercial package that includes a host of features I don't need, and is a Python scripted thing over cloud-based that probably costs a ton, as it relates to processing global imagery. Many thanks for ideas.

1. I cut some pixels and they were replaced by the background color. Erasing didn't work either. Cutting pixels is supposed to make the next layer visible where I've cut the pixels. I had to use a mask.
2. I pasted the pixels and the pixels were empty. (I pasted and limited visibility to the anchored-to layer.)
3. I used the paintbrush (pencil) and it said it would only do white. I couldn't change it to black. Even as a white brush, I couldn't paint the white into an empty layer

Since I don't know how to change default behavior, I have no idea what is wrong. I could copy the file over to my Mac and use Photoshop, but for a quick edit of a PNG file, I'd rather just use Gimp as I've been able to do for the last couple of decades.
But not anymore.

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.
