► Texture Adjustments ◄

CellSize defines pixelated area size on texture.
e.g texture with dimension 512x512, and cellsize 256 and 128

If on texture with dimension with 512x512 you need to have 4x4 'pixels' (note texture size does not change, just pixelated area) CellSize must 4 times smaller (in this case it will be 512 / 4 = 128) than original textures dimension.
From generated texture you have to manually read required pixels as API you are asking is not implemented.

But it will be easier to use only Resize method and specify only required final dimension of the texture. You end up with your desired 2D array of pixels:

Code (CSharp):

1. using UnityEngine;
2.  
3. using VacuumShaders.TextureAdjustments;
4.  
5. public class Test : MonoBehaviour
6. {
7.  
8.     public Texture2D sourceTexture;
9.  
10.     void Start()
11.     {
12.         Adjust_Resize resize = new Adjust_Resize();
13.  
14.         //Setting resize type for 'RESIZE_TYPE.Pixel' for manually controlling final width/height values.
15.         resize.resizeType = Adjust_Resize.RESIZE_TYPE.Pixel;
16.        
17.         resize.width = 16;
18.         resize.height = 16;
19.  
20.         //If enabled 'resize.height' parameter will be calculated automatically
21.         resize.lockAspectRatio = false;
22.  
23.  
24.  
25.         //Resized texture will be saved here
26.         Texture2D newTexture = null;
27.  
28.         //Apply resize
29.         resize.Apply(sourceTexture, ref newTexture);
30.  
31.         //Change filter mode on final texture to have more 'pixelated' look
32.         newTexture.filterMode = FilterMode.Point;
33.     }
34. }
35.

Thank you very much, so i applied above approach however when i do read pixels i get different color values (slightly) even though they are the same colors. I also noticed that your library is closed source so i cant get the color values during pixelate is being applied. So how should i deal with this problem?
Thanks

 

Update 2:

I treid resizing method, but resized image doesnt look like the pixelated version i can see in preview. Im using your code with only following difference
resize.width = destinationTexture.width / (int) InputCellSlider.value;
resize.height = destinationTexture.height / (int) InputCellSlider.value;

Please advise

 

Update 3:
I'd really appreciate if you could return a 2D Array which contains all those Cell values, this will not just be effiecnt but exactly the same as i see in preview.
I cant tell you how much this is important to me.
Thanks

 

All texture adjustments are calculated using shaders, not source .dll. There is no math or some calculation algorithms inside .dll.
Pixelate and Resize are two different effects and their results will be different.
Using Resize was just suggestion as what you are asking for is not implemented. And will not be, as such methods are completely out of the scope of this asset.

Its a shame you cant provide a 2D Array which contains color values of each cell.
Thanks

 

v2018.1 released:
• New improved editor window.
• Added Linear color space support (experimental).
• Added LUT adjustment.
• Added filter mode and transparency view for editor preview texture.
• Improved Pixelation adjustment with grid control.

Note, Linear color space should work by default without any interaction from the user side, but if encounter any problems just let me know.

Hi, will your edge padding feature work on lightmaps? After upgrading from Unity 5.6 to 2017.2 our lightmaps are no longer receiving the push/pull dilation pass Unity normally applies - https://blogs.unity3d.com/wp-content/uploads/2017/10/2017.2_blog_image13.gif

 

Texture Adjustments works with all type of textures unless Unity 'sees' them as Texture2D.

Thank you. Does the dilate/edgepadding require an alpha channel to work?

 

Yes, alpha channel is mandatory.

Hi @Arkhivrag
How can i lower the number of colors in a texture? for example if an image has 256 colors, i can lower to 200 or 180 or 100 etc

 

There is no Indexed Color tool.
Added to a wish-list.



VacuumShaders - Facebook Twitter YouTube

 

Coming update with: Rotator, Crop by Alpha and Crop by Color.









VacuumShaders - Facebook Twitter YouTube

 

Added gradient generator : Linear, Radial, Diamond and Angle.

@Arkhivrag
I noticed 2 recent updates with these new adjustments, can we expect in "Indexed Color tool" in next update. If not then a rough idea?
Thanks

 

Why pixelate effect's cell is not perfectly square? can we provide cell size in width height so we can get the expected cell shape ?

 

Indexed Color tool is added to a wish list. Currently can not say how and when it will be added.

Cell is exactly the perfect square. Will add custom width/height control in the next update.



VacuumShaders - Facebook Twitter YouTube

 

Its not, thats the funny thing, sometimes its perfectly square and sometime its like that

 

Can you provide more details?
Is it editor issue or run-time API use? Can you send me source texture and what Pixelate settings are you using.



VacuumShaders - Facebook Twitter YouTube

 

Its the runtime api, what i do is show a texture from webcam and trigger it from Start
So first time when i run the app , it shows texture like that. however if during runtime i close webcam and select some other texture then it appears fine, if go again to webcam (during same session) it also show webcam texture square.

which means, issue happens at start only once.

 

Unity version and Color space?



VacuumShaders - Facebook Twitter YouTube

 

It's 2018.1 with Gamma.

 

Please provide a way to toggle those border lines in pixelate on and off.

 

Try new update v2018.5



VacuumShaders - Facebook Twitter YouTube

 

It was due to damn WebCam, Your plugin is fine. Sorry.

Another issue is, earlier i was able to know the number of columns and rows, now my old code is not working any more
int totalRows = Mathf.CeilToInt(copyTexture.width / pixelate.pixelCountHorizontal
);
int totalColumns = Mathf.CeilToInt(copyTexture.height / pixelate.
pixelCountVertical
);


another question, do you have any plans for Disintegration effect?

 

Is it texture adjustment effect? May be some examples?

EDIT: I think I solved it from an older post from you
I added screenShot.Apply();
before the rest and for some reason I don't understand, it now works

------------original post-----------

Hi,

I get a gray image after implementing the asset:
declarations:

Code (CSharp):

1.     public Texture2D screenShot;
2.     Texture2D adjustedScreenShot;
3.     public Adjust_Crop crop = new Adjust_Crop();

part of my code:

Code (CSharp):

1.  byte[] bytes;
2.         if (cropAndResize)
3.         {
4.  
5.             //doesn't work
6.             crop.Apply(screenShot, ref adjustedScreenShot);
7.             bytes = adjustedScreenShot.EncodeToJPG(50);
8.         }
9.         else
10.         {
11.             //no changes, works
12.             bytes = screenShot.EncodeToJPG(50);
13.         }
14.         File.WriteAllBytes(myDataPath, bytes);

I also included the crop shader under project settings > graphics

So when I resize, I get a gray image, when I don't resize all works. What could be wrong?

 

Hello Arkhivrag !
Resize Pro last update (with black texture fixed on mobile) is not incorporated into Texture Adjustments. Is it possible to do so ?

Thank you very much !

 

Working on fix.

@Arkhivrag ,

Does this work on Mesh and Sprite textures in runtime? How often to call if not on Update()?

 

This plugin works with all Texture2D objects. Sprite textures - Yes, meshes - No.



VacuumShaders - Facebook Twitter YouTube

 

@Arkhivrag ,

Thanks understood.

 

The asset looks intriguing, and may fill a need I have. Does it handle resizing/scaling while preserving the aspect ratio of the original image?

 

Editor tool has all possible aspect ratio controllers, but with run-rime API you control width and height manually.

Hello

Just want to know is it possible to support ETC/ETC2 compression? (Such as EncodeToETC)
I can't find any information about compressing textures with GPU so I just want to ask about the possibility....

 

If you mean run-time compression, then no.

any plans for adding kaleidoscope effects?

 

Had no plans about kaleidoscope effect before. I need to make research about that effect first.



VacuumShaders - Facebook Twitter YouTube

 

as you have already added complex filters in adjustments, then doing kaleidoscope'd not be an issue for you. keeping my fingers crossed for this.
thanks

 

another request, not sure if its related to texture adjustments

a function that takes a texture, number of rows n columns, and then return array of textures where each index [cell] is that sub texture. this function will cut the big textures into small parts

 

Some kind of multi-crop?



VacuumShaders - Facebook Twitter YouTube

 

yes, please check this picture,
with those cropped pieces, we plugin users'd be able to develop pieces related games such as

 

For that effect you really do not need texture splitting. Each texture will require unique material ==> increase draw calls.
But multi-crop feature is still bookmarked for the next updates.



VacuumShaders - Facebook Twitter YouTube

 

reason i want multicrop is so i can use it with unity ugui's raw image, then i want to apply seperate material on each texture.

 

Split adjustment will be added in the next week update.

For run-time use Texture2D class will have new Split() extension:

Code (CSharp):

1. Texture2D sourceTexture;
2.  
3. Texture2D[] newTextures = sourceTexture.Split(4, 5);

VacuumShaders - Facebook Twitter YouTube

 

Thanks for the update.

Is there any plans for simplify colours or minimize colours?
which we can use with pixelate effects

PS: Happy Christmas

 

Currently no. Added to a wishlist.
But this week update will include some new interesting adjustments.
