Constructor. Creates a new texture object with no texture maps.

Destructor.

Gets parameters to be used when calculating auto size.

Second-phase constructor.

Calculates one size which is most optimal based on all the reported sizes.

Checks if calculated auto size has been changed since last frame.

Clears the texture object and initializes it with solid color pixels. Will setup the logical size and reserve space for the texture if size and segmentation has not yet been prepared.

Clears the texture object and initializes it with solid color pixels. The texture will be initialized with alpha data. Will setup the logical size and reserve space for the texture, if needed.

Enables auto size calculations for this texture.

Caller of this method may observe auto size changes through texture managers MHuiTextureAutoSizeObserver interface.

Generates a blob texture. The texture can be then used for drawing shadow edges, for example.

Determines if the texture has an alpha channel.

Determines whether the texture has content. Only textures that have content can be drawn.

Note that a texture that has not finished loading will return EFalse here, because its content will only become available after it has been fully loaded.

Returns the file name of the texture's source image (if any).

Initialize segment for holding texture data. Allocate texture name etc.

Flag to indicate that auto size calculations for this texture is enabled.

Informs whether this texture is in NVG format or not.

SetNvgContent()

Informs whether this texture is part of skin content or not. By default textures are not part of skin content.

SetSkinContent()

Determines the maximum possible actual (OpenGL/in-memory) size for textures. Typically returns power-of-two dimensions. This limit is usually set by the underlying graphics driver/hardware.

Exported static factory method. Creates a texture appropriate for the current renderer.

Exported static factory method. Creates a texture appropriate for the current renderer.

Notifies one size what would be the most optimal size for this texture. This method can be called e.g. from some CHuiGc image drawing operation which knows the excact size that the image appears in the display.

Updates a partial area of this texture. Does not change the dimensions of the texture (logical size or segmentation).

Returns the priority of the texture

SetPriority()

Releases the texture. The caller is responsible of checking the release priority of the texture.

Resets and removes all texture segments

Delete the texture.

Clears auto size candidates that has been reported (during last frame). This is called by the texture manager after each frame.

Deallocate resources associated with segment. Will free all resources associated with a texture segment. SetSegmentCount()

Deletes the shadow textures.

Restores the texture.

Clear a texture segment to a solid color.

Number of segments in the texture.

ID of the given segment.

Return offset of a segment.

Updates a partial area to a texture segment. Does not change the dimensions of the texture (logical size or segmentation).

Return logical dimensions of a segment.

Return texture dimensions of a segment.

Uploads bitmap data onto a texture segment. Does not change the dimensions of the texture (logical size or segmentation).

Uploads FBS bitmap data onto a texture segment. Does not change the dimensions of the texture (logical size or segmentation).

Gets the session id for object.

Sets parameters to be used when calculating auto size.

Sets the file name of the texture's source image.

Defines whether the texture is in NVG format or not. If the texture is in NVG format, it will not eat up any texture memory. Also the autosizing is being disabled by default, since the sizing is practically free with NVG and OpenVG backend.

EnableAutoSizeCalculation() IsNVGContent()

Sets the placeholder texture. Set to zero to disable the placeholder.

Sets the texture priority. The prioriry is used when the textures are released/restored.

Set segment data. Note that the texture name is allocated when calling InitSegmentL().

Set segment data.

Sets the number of segments. Will delete/create new segments as needed.

Sets the name of a segment.

Sets the logical offset of a texture segment.

Sets the size of a segment.

Sets the texture size of the segment.

Sets the session id for object.

Sets the shadow generation style of the texture.

Set the logical dimensions of the texture. This is the original size of the image loaded as a texture. Also will update (resize) the logical sizes and offsets of texture segments, if such segments have been previously configured.

Size() Use to check the logical size of the texture.

Defines whether the texture is of skin content or not. If this texture is a part of skin content this texture will be released and restored whenever CHuiEnv::NotifySkinChangedL is called. This allows skin specific texture observers to update the content of this texture depending on the skin and it's parameters. Textures that are not part of skin content will be inaffected by the call to the CHuiEnv::NotifySkinChangedL.

CHuiEnv::NotifySkinChangedL() IsSkinContent()

Set texture as (not) changed. Clear the changed flag of this texture once changes have been handled. TextureChanged()

Calculates and sets up segmentation for given size. If the given size exceeds the available maximum texture size, the area is split up to segments having dimensions no more than the maximum texture size.

Determines the current shadow style.

Return logical dimensions of texture. SetSize()

Has texture changed. Check if the texture has changed since the last update.

Set texture as not changed. Clear the changed flag of this texture once changes have been handled. TextureChanged()

Gets the object type.

Uploads the texture data to the texture. Allows using EHuiTextureFlagAllowDirectBitmapUsage flag, but the caller have to take care of deleting the bitmaps.

The bitmaps must be suitable for direct usage. Otherwise this can cause panic in rendering.

Uploads texture data from an FBS bitmap onto this texture.

If the texture uses EHuiTextureFlagAllowDirectBitmapUsage flag, the method CHuiTextureManager::UpdateTextureFromBitmapL() should be used instead. This method leaves with KErrNotSupported in that case.

If the UploadL runs out of memory while uploading/converting the method may try to upload with smaller bitmap sizes and force use of more memory-efficient single-segment texture.

SetSize() Use if you want to change the logical size (for example to fix the aspect ratio of the bitmap) of the texture after uploading.

Uploads bitmap data onto this texture.

Note: This method does NOT support texture segmentation. See the CFbsBitmap upload methods (UploadL()) to create segmented textures.

Flags for texture state.

Index of the active segment.

Flag to indicate that auto size calculations for this texture is enabled

Most optimal size calculated based on all reported sizes

Previous most optimal size calculated based on all reported sizes

Array of content observers.

Name of the image file where the texture was loaded from.

The internal texture state. Composed of THuiTextureFlags.

Temporary texture to use until the real texture has been loaded.

Sizes reported for this texture during last frame

Priority

Names of the segments.

Session id

Shadow generation style.

The logical size of this texture.
