CellMaker Rev

Recommended Posts

Hi, this is a modified version of the Cellmaker plugin by Ego Eram Reputo.

 

Use Effects->Render->CellMaker Rev

 

Download Link > CellMakerRev.zip

I needed to see the center of borders, so i quickly learned how to write a plugin (thanks to CodeLab ;) ). Reading the original post and answers I used the MadJik's coding approach for efficiency.
Here is what it does:

Quote

It simply makes a grid of cells within a given selection. There are three corner options, hard, soft (corner pixels are removed) and rounded (three of the corner pixels are removed for a rounded look).


+ entire/not entire cells option
+ choose start grid reference
+ move grid
+ show borders centers
+ a lot faster then the original plugin
- it has the same flaw of the original plugin:

 

Hidden Content:
The plugin checks only if the 4 corners are visible to draw a cell. So this may happen.

ps: I took the same icon as original plugin, and copy some code from ego eram reputo and MadJik. If this is not allowed I'll delete what's needed.
ps2: I still don't quite understand how some functions works. I've seen a lot of

 

 

for (int y = rect.Top; y < rect.Bottom; y++)
{
for (int x = rect.Left; x < rect.Right; x++)
{
if(selectionRegion.IsVisible(x,y))


But the plugins only works within selected region, so why do that?
Also is there a similar function as selectionRegion.IsVisible(x,y) for segments or areas, because calling IsVisible for a lot pixel is very slow.
Thx

It might have been worthwhile to create a new icon - but I have no special attachment to the one I used. Be my guest and use it and the code as you like.

Yes the IsVisible test is slow, and no it's not really necessary as each pixel, by definition, is inside the current selection.

I like your enhancements! For a first time this is a pretty impressive effort. Bravo!

Would it be possible to add a couple of features to this effect?

1. an adjustable line thicknes

2. adjustable rounded corners

 

To make somethink like this :

That would require quite a rewrite. I'll put it on my list of things to do (which is looong ).

In the short term you might be better to tile a single cell created with the Shapes tool. Rick has added corner radius as an option to the rounded rectangle shape, an of course Shapes support line thickness.

That would be nice. Actually I did use tiling and the rounded rectangle tool tool shape to create the above picture. Another feature that I like of this effect is that the cells can be created inside an irregular selection. I will be patient and wait. :)

Another option is to use @Red ochre's Squirkle then Paste from Clipboard for the tiled effect

How to make cell size more than 255/255?

 

You could try using the 'Grid / Checkerboard' plugin instead; hopefully it fits your needs.

The source is posted in the first post. You could edit the code an recompile it with CodeLab (it's not as hard as it sounds)

 

Here are the lines you need to edit:

 

int Amount1 = 12; // [2,255] Cell Width
int Amount2 = 12; // [2,255] Cell Height

 

In both lines, edit the value 255 and make it something larger to suit your needs. Like this:

 

int Amount1 = 12; // [2,3000] Cell Width
int Amount2 = 12; // [2,3000] Cell Height

^ This will make the maximum size 3000px.

Link to zip file in first post looks like: 37642_8bda1c1802a6068a698cd182433015d6.afdesign (Serif Affinity Designer file? - rename to a .zip and it looks fine)

Yup. Sorry about that. The forum software is screwing up attached file names. 🤔

 

I've reloaded the file in the first post. It now downloads with the correct filename. 👍
