I used the following code in Win 10 PowerShell to create the above images.
input 200,50,1,3 `
rand 0,255 `
+resize 1000,250 `
+blur[-1] 3 `
output gmic_rand.png `
- This is the program I am calling.
- Creates a blank 200x50 blank image...
rand requires a template from which to work.
- The G'MIC command which fills an image with random values.
- The range of these particular values is 0-255 inclusive.
- Passing the same value for both parameters does not cause
rand to choke.
- For tiling patterns,
fill may be more appropriate.
- And for yet other applications,
noise (and all its variations) may be just the ticket.
- The plus in front means add the output of this command to the image list.
- Without it, the image (array, or whatever you want to call the pseudo-image at this point) is altered in place.
- I am impressed with the hardiness of these commands.
- I have not found a way to make
- Maybe negative numbers would work.
gmic help resize is the command to use to discover the available interpolation methods.
+: adds an image to the stack.
- Thus, the transformation is not done in place.
blur: this be the command in question.
- If stumped, might I recommend
gmic help blur.
[-1]: applies the effect to the last image on the stack.
+blur 3) and the blur would be applied to the stack...
- Outputting two additional images (+1 additional image per image already on the stack) rather than the one.
3: The final number is the size of the disk...
- Truthfully, I haven't got the slightest idea how 'the disk' is measured...
- Or even if the fine folks (the very fine folks, indeed), who wrote G'MIC think in terms of disks.
- This is sheer awesomeness!
- The stack is exported twice!
- Also, I don't have to do anything extra to export the entire stack.
- The output images are automatically renamed.
- G'MIC does not care about existing files.
- Name collisions are silently ignored.
- Existing files are happily overwritten.
doesn't quite do the trick, I would look at
(especially for any tiling needs) or the various
) if I were interested in some form of static.
