If an error or warning is detected during the runtime of your GUI application, the error (or warning) code and eventually additional information (known as info, info1 and info2) are output on the debug console of your target device. The following sections provide detailed description of all codes together with few hints to help you to localize and fix the cause of the problem.

Please don't worry about the amount of different error and warning codes addressing the same error case. We use the different codes to distinguish the different locations within the code where the errors can occur. Knowing the error number we can analyze the cause of the error. In case you have the source code of the Run Time Environment and Graphics Engine (available in Professional license of the Platform Package) you can also search in the source code for the given error code number.

Incomplete interface to the underlying graphical subsystem. Missing the implementation of the EwGfxBeginUpdateArea() function.

The 'IssueBuffer' for destination bitmap info1 is too small for polygon data with info2 edges. Adjust in your project the macro definition EW_MAX_ISSUE_TASKS and rebuild the entire application. You can also reduce the number of edges stored in the path.

EwWarpBitmap() operation has been omitted because of the resulting destination area being wider or higher than 4096 pixel. Trying to warp bitmap for such big area will lead to integer arithmetic overflows.

To use EwEnableGfxTaskTracing() you have to rebuild Graphics Engine with the define EW_SUPPORT_GFX_TASK_TRACING. Otherwise the function has no effect.

The support for operations to fill and stroke paths is not available because the Graphics Engine is compiled with the defined macro EW_DONT_USE_PATH_FUNCTIONS.

The support for operations to scale, rotate or warp bitmaps is not available because the Graphics Engine is compiled with the defined macro EW_DONT_USE_WARP_FUNCTIONS.

The support for operations involving EW_PIXEL_FORMAT_INDEX8 bitmaps is not available because the Graphics Engine is compiled with the defined macro EW_DONT_USE_INDEX8_SURFACES.

The support for operations involving EW_PIXEL_FORMAT_RGB565 bitmaps is not available because the Graphics Engine is compiled with the defined macro EW_DONT_USE_RGB565_SURFACES.

No font (NULL) in text extent calculation.

The support for bi-directional text is not available because the Graphics Engine is compiled with the defined macro EW_DONT_USE_BIDI_FUNCTIONS.

Incomplete interface to the underlying graphical subsystem. Missing the implementation of the EwGfxCreateConstNativeSurface() function. This error can occur when your Embedded Wizard project is configured to generate bitmap resources in the DirectAccess format. Please verify the attribute ModeOfBitmapResources in your Embedded Wizard project. You can also try to clean/rebuild your project.

Trying to open an invalid font resource info1.

The font info is not available. Ensure, that the font is installed and registered properly. On the target system use the function EwRegisterFont(). For prototyping, install the font file in the Windows font directory.

Wrong Bitmap Loader and Software Pixel Driver combination. The color formats differ.

The bitmap resource info has not the expected format. Please verify the attribute PlatformPackage in your Embedded Wizard project. It should correspond to the color format of your target system. You can also try to clean/rebuild your project.

The rotation of the bitmap resource info doesn't correspond to the configuration the Graphics Engine has been built for. Please verify whether the attribute ScreenOrientation in your Embedded Wizard project does correctly conform the value of the define EW_SURFACE_ROTATION used during the build process (e.g. within your MAKE file, etc.). You can also try to clean/rebuild your project.

The bitmap resource info is stored with wrong color format. Please verify whether the attributes ColorPremultipliedAlpha and ColorChannelsOrder in your Embedded Wizard project do correctly conform the values of the defines EW_COLOR_CHANNEL_BIT_OFFSET_RED, EW_COLOR_CHANNEL_BIT_OFFSET_GREEN, EW_COLOR_CHANNEL_BIT_OFFSET_BLUE, EW_COLOR_CHANNEL_BIT_OFFSET_ALPHA and EW_PREMULTIPLY_COLOR_CHANNELS used during the build process (e.g. within your MAKE file, etc.). You can also try to clean/rebuild your project.

The RGB565 bitmap resource info is stored with wrong color format. Please verify whether the attribute ColorChannelsOrderOfRGB565 in your Embedded Wizard project does correspond to the values of the defines EW_RGB565_COLOR_CHANNEL_BIT_OFFSET_RED, EW_RGB565_COLOR_CHANNEL_BIT_OFFSET_GREEN and EW_RGB565_COLOR_CHANNEL_BIT_OFFSET_BLUE used during the build process (e.g. within your MAKE file, etc.).

Wrong Bitmap Loader and Software Pixel Driver combination. Color format differ.

The image file info is not available or the format of the image file is not supported by the extern loader. Ensure, that a valid file is available on the target system.

Trying to load an invalid bitmap resource info1.

Wrong Viewport Interface and Pixel Driver combination.

Timer info1 not in the timers list.

String index out of the string length.

Trying to modify a constant string.

Trying to release a string with usage counter 0.

Object info1 is not in the root set.

The specified class parameter to create a new instance is not a valid class.

Recursive access to an autoobject info1 performing the initialization.

Trying to use the function EwSetStackBaseAddress() with Runtime Environment not configured to run Immediate Garbage Collection. Operation is ignored.

No CPU stack information available to start the Immediate Garbage Collection. Please call the function EwSetStackBaseAddress() at the initialization time of the application to provide to the Runtime Environment the base address of the CPU stack. Immediate Garbage Collection is not started.

New Garbage Collection started while the actual Garbage Collection is not yet finished. Recursive Garbage Collections are not permitted. Operation is ignored.

Try to use the function EwModifyBitmapPalette() to modify the palette of loaded originally from a resource. Such bitmaps and their associated palettes are considered as immutable. Operation is ignored. info1 contains the address of the respective bitmap.

Failed to map the frame with number info2 of the bitmap info1.

Trying to use EwAllocHeapBlock() without initializing the Heap Manager. Use EwInitHeap() and EwAddHeapMemoryPool() first.

Trying to use EwFreeHeapBlock() with an invalid memory block address or the internal heap management structures are corrupted. In the last case you can use the function EwVerifyHeap() to check the heap for its coherence.

The memory area specified in the function call EwAddHeapMemoryPool() is too small to be added to the memory pool of the Heap Manager. The operation is ignored.

The function EwVerifyHeap() has detected an incoherence in internal Heap Management structures. info1 specifies the address of the affected memory area within the memory pool (see function EwAddHeapMemoryPool()). info2 specifies the number of the failed coherence test.

Trying to perform a drawing operation within a bitmap loaded originally from a resource. Such bitmaps are considered as immutable. Operation is ignored. info1 contains the address of the respective bitmap. info2 contains the specified frame number.
