Description

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

The operation is quite simple: Create a texture builder, set all the necessary properties - keep in mind that the properties GLTextureBuilder:context, GLTextureBuilder:id, GLTextureBuilder:width, and GLTextureBuilder:height are mandatory - and then call gLTextureBuilderBuild 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.

build

gLTextureBuilderBuild Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> Maybe DestroyNotify	`destroy`: destroy function to be called when the texture is released
-> Ptr ()	`data`: user data to pass to the destroy function
-> m Texture	Returns: a newly built `GdkTexture`

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

The destroy function gets called when the returned texture gets released; either when the texture is finalized or by an explicit call to gLTextureRelease. It should release all GL resources associated with the texture, such as the GLTextureBuilder:id and the GLTextureBuilder:sync.

Note that it is a programming error to call this function if any mandatory property has not been set.

It is possible to call this function multiple times to create multiple textures, possibly with changing properties in between.

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a, IsGLContext b)
=> a	`self`: a `GdkGLTextureBuilder`
-> Maybe b	`context`: The context the texture beongs to or `Nothing` to unset
-> m ()

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

The context must be set before calling gLTextureBuilderBuild.

Since: 4.12

setFormat

gLTextureBuilderSetFormat Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> MemoryFormat	`format`: The texture's format
-> m ()

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

The format is the preferred format the texture data should be downloaded to. The format must be supported by the GL version of GLTextureBuilder:context.

GDK's texture download code assumes that the format corresponds to the storage parameters of the GL texture in an obvious way. For example, a format of GDK_MEMORY_R16G16B16A16_PREMULTIPLIED is expected to be stored as GL_RGBA16 texture, and GDK_MEMORY_G8A8 is expected to be stored as GL_RG8 texture.

Setting the right format is particularly useful when using high bit depth textures to preserve the bit depth, to set the correct value for unpremultiplied textures and to make sure opaque textures are treated as such.

Non-RGBA textures need to have swizzling parameters set up properly to be usable in GSK's shaders.

Since: 4.12

setHasMipmap

gLTextureBuilderSetHasMipmap Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> Bool	`hasMipmap`: Whether the texture has a mipmap
-> m ()

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

Typically, the glGenerateMipmap function is used to generate a mimap.

Since: 4.12

setHeight

gLTextureBuilderSetHeight Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> Int32	`height`: The texture's height or 0 to unset
-> m ()

Sets the height of the texture.

The height must be set before calling gLTextureBuilderBuild.

Since: 4.12

setId

gLTextureBuilderSetId Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> Word32	`id`: The texture id to be used for creating the texture
-> m ()

Sets the texture id of the texture. The texture id must remain unmodified until the texture was finalized. See gLTextureBuilderBuild for a longer discussion.

The id must be set before calling gLTextureBuilderBuild.

Since: 4.12

setSync

gLTextureBuilderSetSync Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> Ptr ()	`sync`: the GLSync object
-> m ()

Sets the GLSync object to use for the texture.

GTK will wait on this object before using the created GdkTexture.

The destroy function that is passed to gLTextureBuilderBuild is responsible for freeing the sync object when it is no longer needed. The texture builder does not destroy it and it is the callers responsibility to make sure it doesn't leak.

Since: 4.12

setUpdateRegion

gLTextureBuilderSetUpdateRegion Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> Maybe Region	`region`: the region to update
-> m ()

Sets the region to be updated by this texture. Together with GLTextureBuilder:updateTexture this describes an update of a previous texture.

When rendering animations of large textures, it is possible that consecutive textures are only updating contents in parts of the texture. It is then possible to describe this update via these two properties, so that GTK can avoid rerendering parts that did not change.

An example would be a screen recording where only the mouse pointer moves.

Since: 4.12

setUpdateTexture

gLTextureBuilderSetUpdateTexture Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a, IsTexture b)
=> a	`self`: a `GdkGLTextureBuilder`
-> Maybe b	`texture`: the texture to update
-> m ()

Sets the texture to be updated by this texture. See gLTextureBuilderSetUpdateRegion for an explanation.

Since: 4.12

setWidth

gLTextureBuilderSetWidth Source #

Arguments

:: (HasCallStack, MonadIO m, IsGLTextureBuilder a)
=> a	`self`: a `GdkGLTextureBuilder`
-> Int32	`width`: The texture's width or 0 to unset
-> m ()

Sets the width of the texture.

The width must be set before calling gLTextureBuilderBuild.

Since: 4.12
