The OPTIMIZEIMAGEOPTIONS structure provides options to be used by the Image Optimization functions to optimize the image and save it using the optimal bits per pixel.

Member	Description
uStructSize	Size of this structure in bytes, for versioning. Use the sizeof() macro to calculate this value.
uJPEGQFactor	Value that represents the quality factor used in the image optimization operation. The uJPEGQFactor is a number that determines the degree of loss in the compression process. You can set a value from 2 to 255, where 2 represents the highest quality and 255 represents the most compression. This value is used only if the original image format is one of the JPEG values in LEAD Image Optimizer Supported Formats. The default value is 35.
uPNGQFactor	Value that represents the quality factor to be used in the image optimization operation. The uPNGQFactor can be a value between 0 and 10 where 0 = default compression 1 = fastest compression . . . 9 = highest compression ratio 10 = no compression This value is used only if the original image format is (FILE_PNG). The Default value is 9.
JPEGColorSpace	Value that represents the color space to be used in the image optimization operation if and only if the original image format one of the JPEG values in LEAD Image Optimizer Supported Formats. For more information refer to JPEGCOLORSPACE. The default value is JPEG_COLORSPACE_411.
nPercent	Value that represents the percent of redundancy to be used in the image optimization operation. This value will be used if the original image format was: PNG File (FILE_PNG). GIF File (FILE_GIF). One of BMP values in LEAD Image Optimizer Supported Formats with 1, 4, and 8 bits per pixel only. The nPercent value can be a value between 0 and 100. The default value is 10.
uDistance	Value that represents the distance between image colors to be reduced in the image optimization operation. This value will be used if the original image format was: PNG File (FILE_PNG). GIF File (FILE_GIF). One of LEAD Supported BMP Format with 1, 4, and 8 bits per pixel only. The uDistance value can be a value between 0 and 255, where: 0 means no additional reduction. 1 to 255 further reduction based on the color distance The default value is 8.
bPickSamePalette	Flag that indicates whether to generate a unique global palette for all GIF frames or generate a separate palette for each frame. Possible values are:
	Value	Meaning
	TRUE	Generate a unique global palette for all GIF Frames.
	FALSE	Generate an individual palette for each GIF Frame. (Default)
