MemoryTextureBuilder

Object Hierarchy:

Description:

[ CCode ( type_id = "gdk_memory_texture_builder_get_type ()" ) ]
[ Version ( since = "4.16" ) ]
public class MemoryTextureBuilder : Object

Constructs [class@Gdk.

Texture] objects from system memory provided via [struct@GLib.Bytes].

The operation is quite simple: Create a texture builder, set all the necessary properties - keep in mind that the properties [ property@Gdk.MemoryTextureBuilder:bytes], [property@Gdk.MemoryTextureBuilder:stride], [property@Gdk.MemoryTextureBuilder:width], and [ property@Gdk.MemoryTextureBuilder:height] are mandatory - and then call [method@Gdk.MemoryTextureBuilder.build] to create the new texture.

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

Namespace: Gdk

Package: gtk4

Properties:

public Bytes bytes { get; set; }
The bytes holding the data.
public ColorState color_state { get; set; }
The colorstate describing the data.
public MemoryFormat format { get; set; }
The format of the data.
public int height { get; set; }
The height of the texture.
public uint64 stride { get; set; }
The rowstride of the texture.
public Region update_region { get; set; }
The update region for [property@Gdk.
public Texture update_texture { get; set; }
The texture [property@Gdk.
public int width { get; set; }
The width of the texture.

Creation methods:

public MemoryTextureBuilder ()
Creates a new texture builder.

Methods:

public Texture build ()
Builds a new `GdkTexture` with the values set up in the builder.
public unowned Bytes? get_bytes ()
Gets the bytes previously set via set_bytes or null if none was set.
public unowned ColorState get_color_state ()
Gets the colorstate previously set via set_color_state.
public MemoryFormat get_format ()
Gets the format previously set via set_format.
public int get_height ()
Gets the height previously set via set_height or 0 if the height wasn't set.
public size_t get_offset (uint plane)
Gets the offset previously set via set_offset.
public size_t get_stride ()
Gets the stride previously set via set_stride.
public size_t get_stride_for_plane (uint plane)
Gets the stride previously set via set_stride_for_plane.
public unowned Region? get_update_region ()
Gets the region previously set via set_update_region or null if none was set.
public unowned Texture? get_update_texture ()
Gets the texture previously set via set_update_texture or null if none was set.
public int get_width ()
Gets the width previously set via set_width or 0 if the width wasn't set.
public void set_bytes (Bytes? bytes)
Sets the data to be shown but the texture.
public void set_color_state (ColorState color_state)
Sets the colorstate describing the data.
public void set_format (MemoryFormat format)
Sets the format of the bytes.
public void set_height (int height)
Sets the height of the texture.
public void set_offset (uint plane, size_t offset)
Sets the offset of the texture for plane.
public void set_stride (size_t stride)
Sets the rowstride of the bytes used.
public void set_stride_for_plane (uint plane, size_t stride)
Sets the stride of the texture for plane.
public void set_update_region (Region? region)
Sets the region to be updated by this texture.
public void set_update_texture (Texture? texture)
Sets the texture to be updated by this texture.
public void set_width (int width)
Sets the width of the texture.
