Blit

int32_t(* GfxFuncs::Blit) ([ISurface]($api-api-SmartVision-Devices-ISurface.md) *srcSurface, [IRect]($api-api-SmartVision-Devices-IRect.md) *srcRect, [ISurface]($api-api-SmartVision-Devices-ISurface.md) *dstSurface, [IRect]($api-api-SmartVision-Devices-IRect.md) *dstRect)

Description:

Blits bitmaps.

During bit blit, color space conversion (CSC), scaling, and rotation can be implemented.

Parameters:

Name	Description
srcSurface	Indicates the pointer to the source bitmap.
srcRect	Indicates the pointer to the rectangle of the source bitmap.
dstSurface	Indicates the pointer to the destination bitmap.
dstRect	Indicates the pointer to the rectangle of the destination bitmap.

Returns:

Returns 0 if the operation is successful; returns an error code defined in DispErrCode otherwise.

DeinitGfx

int32_t(* GfxFuncs::DeinitGfx) (void)

Description:

Deinitializes hardware acceleration.

Returns:

Returns 0 if the operation is successful; returns an error code defined in DispErrCode otherwise.

Parameters:

Name	Description
surface	Indicates the pointer to the canvas.
line	Indicates the pointer to the line to draw.
opt	Indicates the pointer to the hardware acceleration option.

Returns:

Returns 0 if the operation is successful; returns an error code defined in DispErrCode otherwise.

int32_t(* GfxFuncs::DrawRectangle) ([ISurface]($api-api-SmartVision-Devices-ISurface.md) *surface, [Rectangle]($api-api-SmartVision-Devices-Rectangle.md) *rect, uint32_t color, [GfxOpt]($api-api-SmartVision-Devices-GfxOpt.md) *opt)

Description:

Draws a rectangle with a given color on the canvas.

Parameters:

Name	Description
surface	Indicates the pointer to the canvas.
rect	Indicates the pointer to the rectangle to draw.
color	Indicates the color to draw.
opt	Indicates the pointer to the hardware acceleration option.

int32_t(* GfxFuncs::FillRect) ([ISurface]($api-api-SmartVision-Devices-ISurface.md) *surface, [IRect]($api-api-SmartVision-Devices-IRect.md) *rect, uint32_t color, [GfxOpt]($api-api-SmartVision-Devices-GfxOpt.md) *opt)

Description:

Fills a rectangle with a given color on the canvas.

Parameters:

Name	Description
surface	Indicates the pointer to the canvas.
rect	Indicates the pointer to the rectangle to fill.
color	Indicates the color to fill.
opt	Indicates the pointer to the hardware acceleration option.

Returns:

Returns 0 if the operation is successful; returns an error code defined in DispErrCode otherwise.

InitGfx

int32_t(* GfxFuncs::InitGfx) (void)

Description:

Initializes hardware acceleration.

Returns:

Returns 0 if the operation is successful; returns an error code defined in DispErrCode otherwise.

See also:

DeinitGfx

Sync

int32_t(* GfxFuncs::Sync) (void)

Description:

Synchronizes hardware acceleration.

Use this function for hardware acceleration synchronization when hardware acceleration is used to draw and blit bitmaps. This function blocks the process until hardware acceleration is complete.

Parameters:

Name	Description
timeOut	Indicates the timeout duration for hardware acceleration synchronization. The value 0 indicates no timeout, so the process waits until hardware acceleration is complete.

Returns:

Returns 0 if the operation is successful; returns an error code defined in DispErrCode otherwise.
