Solid Noise FAQ
How do I set the image mode?
The image mode is automatically read from the properties of the currently selected layer.
What color and image modes does Plasma support?
Plasma currently supports 8- and 16-bit RGB or grayscale modes.
Is Plasma available for 64-bit Photoshop or for Macs?
The filter is currently only available for the 32-bit version of Adobe Photoshop®. I plan to make it available in both versions shortly after the filter compiler supports 64-bit computation.
I wish to port the filter to Mac sometime in the future.
Where is the "Plug-Ins" directory?
This depends on where Photoshop was installed. Generally, the default directory is: Program Files → Adobe → Adobe Photoshop CS6 → Plug-ins.
If the filter was installed through Adobe Exchange CS6, it should install into the correct directory automatically, but Photoshop will need to be restarted before the filter appears in Photoshop’s Filter → Render sub-menu.
Is Plasma usable in Actions or scripting?
Why does the Preview image color sometimes differ a little from the final image?
The Preview is calculated on a reduced size image specified by the full-size image dimensions multiplied (approximately) by the zoom factor displayed under the preview window. This size difference compared to the full image causes the algorithm calculations to vary a little.
Briefly, the rectangles are reduced in half-size stages, but at the smallest sizes, the preview image rectangles may not have center pixels where the full-size image rectangles do. This changes the averaging result, thus affecting the final image color in some cases. To some extent, this is the nature of the algorithm, but it can be mitigated by changing the Zoom level. If you notice drastic differences, you may report it.
Does it work with other applications?
It will likely work in Photoshop CS5.x, and I expect that the Plasma filter will work in Adobe Fireworks® CS6 and PaintShopPro®, but it has not yet been tested in these applications. You may copy the filter for testing and use in Fireworks or PaintShopPro installation that is also licensed to you. You are welcome to let me know what you find via my website. If there is enough interest in these alternative applications, I will consider making it publicly available there.
Can I distribute Plasma?
While this implementation of Plasma is distributed for free, the code and accompanying files are currently copyrighted. Briefly, Plasma may be redistributed on an individual person-to-person basis, but it is not permitted to distribute or repackage it (for free or fee) via any other distribution method or channel without explicit written permission.
