Detailed Description

A base class for image loader plugin iImage implementations.

Member Function Documentation

static const char* csCommonImageFile::DataTypeString ( csLoaderDataType  dataType  )  [static, protected]

Convert an image loader data type into a raw data description (if supported).

virtual const uint8* csCommonImageFile::GetAlpha (  )  [protected, virtual]

Get alpha map for 8-bit paletted image.

RGBA images contains alpha within themself. If image has no alpha map, or the image is in RGBA format, this function will return 0.

Reimplemented from csImageMemory.

virtual const void* csCommonImageFile::GetImageData (  )  [protected, virtual]

Get image data: returns either (csRGBpixel *) or (unsigned char *) depending on format.

Note that for RGBA images the csRGBpixel structure contains the alpha channel as well, so GetAlpha (see below) method will return 0 (because alpha is not stored separately, as for paletted images).

Reimplemented from csImageMemory.

virtual void csCommonImageFile::GetKeyColor ( int &  r,
int &  g,
int &  b 
) const [inline, protected, virtual]

Get the keycolour stored with the image.

Reimplemented from csImageMemory.

Definition at line 203 of file commonimagefile.h.

virtual const csRGBpixel* csCommonImageFile::GetPalette (  )  [protected, virtual]

Get image palette (or 0 if no palette).

Reimplemented from csImageMemory.

virtual csRef<iDataBuffer> csCommonImageFile::GetRawData (  )  const [protected, virtual]

Get the raw data of the image (or 0 if raw data is not provided).

Reimplemented from csImageBase.

virtual const char* csCommonImageFile::GetRawFormat (  )  const [protected, virtual]

Get a string identifying the format of the raw data of the image (or 0 if raw data is not provided).

Reimplemented from csImageBase.

virtual bool csCommonImageFile::HasKeyColor (  )  const [inline, protected, virtual]

Check if image has a keycolour stored with it.

Reimplemented from csImageMemory.

Definition at line 192 of file commonimagefile.h.

virtual csRef<iImageFileLoader> csCommonImageFile::InitLoader ( csRef< iDataBuffer source  )  [protected, pure virtual]

Create a loader object, which will handle the actual loading.

Note: the returned loader should have a proper width, height, format, data type and keycolor flag (note not the actual color) already set.

virtual bool csCommonImageFile::Load ( csRef< iDataBuffer source  )  [protected, virtual]

Load an image from a data buffer.

void csCommonImageFile::MakeImageData (  )  [protected]

Convert data from the loader to actual image data.

void csCommonImageFile::WaitForJob (  )  const [protected]

Wait for the current image loading job to finish.
