Resize(int, int)

Resizes the texture.
Warning
Deprecated. Texture2D.Resize(int, int) has been deprecated because it actually reinitializes the texture. Use Texture2D.Reinitialize(int, int) instead
Upgrade to Texture2D.Reinitialize
public bool Resize(int width, int height)

Parameters

width

int

height

int

Returns

Type

Description

bool

Remarks

Changes size of texture to 
width
by 
height
. After resizing, texture pixels will be undefined. This function is very similar to texture constructor, except it works on existing texture object.
Call Texture2D.Apply to actually upload the changed pixels to the graphics card.
Texture.isReadable must be 
true
.
Note that Resize does not automatically update the special texture properties {TextureName}
_TexelSize
and {TextureName}
_HDR
that are set automatically on shaders and materials that use the texture. After using Resize, you should update these properties manually on your material/shader if you need them.

Resize(int, int, TextureFormat, bool)

Resizes the texture.
Warning
Deprecated. Texture2D.Resize(int, int, TextureFormat, bool) has been deprecated because it actually reinitializes the texture. Use Texture2D.Reinitialize(int, int, TextureFormat, bool) instead
Upgrade to Texture2D.Reinitialize
public bool Resize(int width, int height, TextureFormat format, bool hasMipMap)

Parameters

width

int

height

int

format

TextureFormat

hasMipMap

bool

Returns

Type

Description

bool

Remarks

Obsolete: Use Texture2D.Reinitialize instead.
Changes size of texture to 
width

textureFormat
and optionally creates mipmaps. After resizing, texture pixels will be undefined. This function is very similar to the texture constructor, except it works on existing texture object.
