### Class

# GdkGLTextureBuilder

since: 4.12

#### Description [src]

    final class Gdk.GLTextureBuilder : GObject.Object
    {
      /* No available fields */
    }

`GdkGLTextureBuilder` is a builder used to construct `GdkTexture` objects from GL textures.

The operation is quite simple: Create a texture builder, set all the necessary properties - keep in mind that the properties `GdkGLTextureBuilder:context`, `GdkGLTextureBuilder:id`, `GdkGLTextureBuilder:width`, and `GdkGLTextureBuilder:height` are mandatory - and then call `gdk_gl_texture_builder_build()` to create the new texture.

`GdkGLTextureBuilder` can be used for quick one-shot construction of textures as well as kept around and reused to construct multiple textures.

###### gdk_gl_texture_builder_build

Builds a new `GdkTexture` with the values set up in the builder.

since: 4.12

###### gdk_gl_texture_builder_get_context

Gets the context previously set via `gdk_gl_texture_builder_set_context()` or `NULL` if none was set.

since: 4.12

Gets the format previously set via gdk_gl_texture_builder_set_format().

since: 4.12

###### gdk_gl_texture_builder_get_has_mipmap

Gets whether the texture has a mipmap.

since: 4.12

###### gdk_gl_texture_builder_get_height

Gets the height previously set via `gdk_gl_texture_builder_set_height()` or 0 if the height wasn’t set.

since: 4.12

###### gdk_gl_texture_builder_get_id

Gets the texture id previously set via `gdk_gl_texture_builder_set_id()` or 0 if the id wasn’t set.

since: 4.12

###### gdk_gl_texture_builder_get_sync

Gets the `GLsync` previously set via gdk_gl_texture_builder_set_sync().

since: 4.12

###### gdk_gl_texture_builder_get_update_region

Gets the region previously set via `gdk_gl_texture_builder_set_update_region()` or `NULL` if none was set.

since: 4.12

###### gdk_gl_texture_builder_get_update_texture

Gets the texture previously set via `gdk_gl_texture_builder_set_update_texture()` or `NULL` if none was set.

since: 4.12

###### gdk_gl_texture_builder_get_width

Gets the width previously set via `gdk_gl_texture_builder_set_width()` or 0 if the width wasn’t set.

since: 4.12

###### gdk_gl_texture_builder_set_context

Sets the context to be used for the texture. This is the context that owns the texture.

since: 4.12

###### gdk_gl_texture_builder_set_format

Sets the format of the texture. The default is `GDK_MEMORY_R8G8B8A8_PREMULTIPLIED`.

since: 4.12

###### gdk_gl_texture_builder_set_has_mipmap

Sets whether the texture has a mipmap. This allows the renderer and other users of the generated texture to use a higher quality downscaling.

since: 4.12

###### gdk_gl_texture_builder_set_height

Sets the height of the texture.

since: 4.12

###### gdk_gl_texture_builder_set_id

Sets the texture id of the texture. The texture id must remain unmodified until the texture was finalized. See `gdk_gl_texture_builder_build()` for a longer discussion.

since: 4.12

###### gdk_gl_texture_builder_set_sync

Sets the GLSync object to use for the texture.

since: 4.12

###### gdk_gl_texture_builder_set_update_region

Sets the region to be updated by this texture. Together with `GdkGLTextureBuilder:update-texture` this describes an update of a previous texture.

since: 4.12

###### gdk_gl_texture_builder_set_update_texture

Sets the texture to be updated by this texture. See `gdk_gl_texture_builder_set_update_region()` for an explanation.

since: 4.12

###### gdk_gl_texture_builder_set_width

Sets the width of the texture.
