Problem with resize sprite or texture 2d

Code (CSharp):

1. Texture2D SpriteTexture = LoadTexture(FilePath);
2. Sprite NewSprite = Sprite.Create(SpriteTexture, new Rect(0, 0, SpriteTexture.width, SpriteTexture.width), new Vector2(0, 0), 100.0f, 0, SpriteMeshType.FullRect);

The first line calls the method which, according to the path, finds the image and returns it as a texture. In the second line I create a sprite using the texture.

However, my image has a resolution of 250x250 px and I want to reduce it to 150x150.

I have tried doing resize texture or changing something in the sprite creation parameters. In the end the image either gets larger or disappears altogether. What are the options for solving my query?

 

you will have to resize the image in your image editor program, theres no feature to resize images in unity

 

Wouldn't shrinking a sprite also shrink the texture with which the sprite was created?
Or is there nothing that could have been changed during the texture from image generation phase?

 

you can look up something called "render textures" and try to create a new texture using that but it will involve extra coding steps, it wont be as easy as just choosing the new size and it just scales like you were using an image editor like photoshop
