IWICLeadBitmapEncoder::GetProgressiveOptions Method
Show in webframe
Gets a list of the valid progressive options for a LEAD Bitmap encoder.
Gets a list of the valid progressive options for a LEAD Bitmap encoder.
HRESULT GetProgressiveOptions(
WICPixelFormatGUID guidPixelFormat,
UINT uSubFormatIndex,
UINT cbSizeProgressiveOptions,
INT *pProgressiveOptions,
UINT *pcProgessiveOptions
);
- guidPixelFormat
- [in] The pixel format GUID that the encoder is usingWICLeadEnumName.
- uSubFormatIndex
- [in] The index of the sub-format array returned by the GetSubFormats method.
- cbSizeProgressiveOptions
- [in] The size of the pProgessiveOptions buffer.
- pProgressiveOptions
- [in,out] A pointer that receives a list of progressive options supported by the encoder.
- pcProgressiveOptions
- [in,out] A pointer that receives the number of progressive options the encoder supports.
Returns S_OK if successful, or an error value otherwise.
Some image formats can be compressed with progressive passes. This means that the image data is stored with a succession of image scans that are derived from approximations of the original image. The first image scan is typically of low accuracy. Additional scans are used to gradually refine the image. The WIC-Enabled LEAD Bitmap Encoders that support progressive scans include Cmp, Jpeg, Mng, and Jbig. Set the passes property bag item with a valid value to save these image formats with progressive passes.
Use the GetProgressiveOptions method to get a list of the valid progressive options for a LEAD Bitmap Encoder. First call GetSubFormats to get an array of valid sub-formats for the particular LEAD bitmap encoder. When calling the GetProgressiveOptions method, pass the index of the sub-format array for the uSubFormatIndex argument.
Call GetProgressiveOptions once to get number of supported predefined quality factors. Allocate the appropriately sized array. Then call GetProgressiveOptions again, passing the allocated array as an argument. The example illustrates this technique.
To get a printable name for any of the progressive options, call the IWICLeadBitmapEncoder_GetProgressiveOptionsFriendlyName method.
