Axis Streak

[Reptillian 303]

This plugin streaks pixels along an axis. In non-transparent black and white image, it does more than just streaking, it actually calculate distance away to end and insert it into the canvas. There are 2 options here, the direction to streak pixels, and the exponential factor. It's not meant to work with non-transparent rgb image since there are many edge detection algorithm, so that part is left to you if you want to use it on a non-transparent rgb image. It does work with transparent images regardless of whether it's black and white or colored.

 

Output of Effect:

 

This was done by two steps.

1) Edge detect, and then put the output into alpha channel of non-transparent rgb image.

2) Use Axis Streak

 

How to install:

 

Download the zip, and extract it directly into the Effects folder (If you already have GmicSharpNative folder). -> AxisStreakGmicPDN.zip

 

It should be under 'Distort'. It only works for the following:

• Non-transparent grayscale image (This result in distance mode. The closer to the edge, the darker the pixel are.)
• Transparent Images

It does not work for this case: Non-transparent Colored Image

 

If you don't have 'GmicSharpNativefolder' : Download GMICSharpNative, and extract 'GmicSharpNative' into plugin installation folder named 'Effects'.

Yes. I still haven't gotten around the x86, and didn't managed to build it at all via instruction from @null54

This was done by two steps.

1) Edge detect, and then put the output into alpha channel of non-transparent rgb image.

2) Use Axis Streak

 

You may need to explain this. Not everyone is going to understand. Which Edge Detect plugin did you use? I have 2 different ones.

I was trying to get it to work on rgb images. Works fine on black & white.  Thanks!

I used Afre's edge detect in gmic-qt as it result in black and white edge. Then I assigned it to the alpha channel to rgb image. Yes, the rgb image needs to be transparent for the plugin to work.

 

It works in non-transparent black and white because I coded the distance mode for Perspective Streak within G'MIC-QT as it works reasonably well because of less variety along alpha, and hence it is part of the plugin. Making it work with non-transparent rgb is out of scope for the plugin as I would need to add edge detection and insert it into alpha.

@Reptillian, thank you for your time and effort in making plugins for all of us to use. I'm sure I'm just one of many who appreciate your trouble and willingness to offer to the community.

So please don't take this the wrong way, but you seem to put a lot of effort into developing and then just not bother how your plugins are received, appreciated or used. You do yourself great dis-justice by not taking the time to write clear and precise instructions for installing your plugins (if the installation is not the standard one - yes, repeat the same "g'mic sharp" instructions for each plugin if necessary), possible limitations, how-to's and examples.

The thing is that I'm always tired, so all I can honestly do is to leave the plugins out there, and try my best to provide at least the minimum instruction. I just do not want to bother putting more efforts than I want to.

 

I sometime do provide limitation, like in the OP such as it's not intended to work with non-transparent colored image. It can work with transparent images or non-transparent black and white image.

I did this and got black background with white edges. Good so far.

Haven't a clue how to do this. Can you explain a little more, please?  Thanks.

Full instructions:

 

1. Duplicate the image into a new layer.

2. Apply afre's edge detect to the duplicate image.

3. Copy the edge detect result into clipboard.

4. Run Alpha Mask into the unaffected layer and have paste from clipboard checkmarked.

5. Run Axis Streak.

Now, I unarchived it, you should be able to download. I thought people could download it, but that might has to do with me being logged in, so I didn't know.
