Detailed Description

Texture creation parameters for two dimensional texture.

You can use resulting texture as content in Image2D nodes or texture brushes, or in materials for 3D rendering or material brushes.

Constructor & Destructor Documentation

CreateInfo2D() [1/3]

kanzi::Texture::CreateInfo2D::CreateInfo2D ( BitmapImageUniquePtr  image )

explicit

CreateInfo2D constructor for texture creation parameters, for creating a two dimensional texture that is initialized from an image.

After the CreateInfo2D constructor:

• Image is stored in create info.
• Texture type is set to TypeTwoDimensional.
• Texture size and format is determined from the image.

The following (from CreateInfo constructor) also applies:

• Texture minification and magnification filter settings are set to FilterNearest.
• Texture wrap mode is set to AddressingModeClamp, so texture will not repeat.
• Texture mipmap mode is set to MipmapModeBase, and mipmapLevelCount is set to 1, so texture will have only base image, no mipmaps.

Note

After constructor, due to filter settings and lack of mipmaps, the resulting texture should only be used when texture content is shown without scaling. If you show resulting texture content with scaling, the result has noticeable aliasing. Adjust filter and mipmap settings after constructor to reduce aliasing.

Texture::create() takes ownership of images you pass in the create info,

See also

Texture::create().

Image

Parameters

image

Source image for texture.

CreateInfo2D() [2/3]

kanzi::Texture::CreateInfo2D::CreateInfo2D ( Sampler::MipmapMode  mipmaps, BitmapImageUniquePtr  image  )

explicit

CreateInfo2D constructor that also takes in mipmap mode.

For details, see CreateInfo2D(BitmapImageUniquePtr)

Parameters

mipmaps	Mipmap mode.
image	Source image for texture.

CreateInfo2D() [3/3]

kanzi::Texture::CreateInfo2D::CreateInfo2D ( unsigned int  width, unsigned int  height, GraphicsFormat  format  )

explicit

CreateInfo2D constructor for texture creation parameters, for creating a two dimensional texture with specified format and size.

After the CreateInfo2D constructor:

• Texture type is set to TypeTwoDimensional.
• Texture size and format is set according to constructor parameters.

The following (from CreateInfo constructor) also applies:

• Texture minification and magnification filter settings are set to FilterNearest.
• Texture wrap mode is set to AddressingModeClamp, so texture will not repeat.
• Texture mipmap mode is set to MipmapModeBase, and mipmapLevelCount is set to 1, so texture will have only base image, no mipmaps.
• Texture rendertarget mode is set to RenderTargetModeNone, so resulting texture cannot be set as rendertarget for neither 2d nodes nor renderpasses. If you want to render to the resulting texture, change rendertarget mode.

Note

After constructor, due to filter settings and lack of mipmaps, the resulting texture should only be used when texture content is shown without scaling. If you show resulting texture content with scaling, the result has noticeable aliasing. Adjust filter and mipmap settings after constructor to reduce aliasing.

When you create texture from CreateInfo that has no images, texture contents are initially undefined. Use Texture::setData() to specify texture contents, or render to the texture.

Parameters

width	Width for the texture
height	Height for the texture
format	Format for the texture
