IG_pixel_create

In This Topic

This function creates a new pixel object based on specified attributes.

Declaration:

	Copy Code
HIGPIXEL ACCUAPI IG_pixel_create( AT_INT channelCount, AT_DEPTH bitsPerChannel );

Arguments:

Name	Type	Description
channelCount	AT_INT	Number of channels to allocate.
bitsPerChannel	AT_DEPTH	Bits per channel to allocate.

Return Value:

Handle of new pixel object.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Sample:

Pixel Access

Example:

	Copy Code
AT_ERRCOUNT nErrcount; /* Number of errors on stack / HIGEAR hImage; / Handle of image / HIGPIXEL hPix; / Handle of pixel / AT_INT ChannelCount; / Number of channels in image / AT_INT BitsPerChannel; / Bits per channel in image / nErrcount = IG_load_file("test.jpg", &hImage); nErrcount = IG_image_channel_count_get(hImage, &ChannelCount); nErrcount = IG_image_bits_per_channel_get(hImage, &BitsPerChannel); hPix = IG_pixel_create(ChannelCount, BitsPerChannel); / Pixel is created using same attributes as image */ IG_pixel_delete(hPix); IG_image_delete(hImage);

Copy Code

AT_ERRCOUNT nErrcount;  /* Number of errors on stack */
HIGEAR hImage;          /* Handle of image */
HIGPIXEL hPix;          /* Handle of pixel */
AT_INT ChannelCount;    /* Number of channels in image */
AT_INT BitsPerChannel;  /* Bits per channel in image */
nErrcount = IG_load_file("test.jpg", &hImage);
nErrcount = IG_image_channel_count_get(hImage, &ChannelCount);
nErrcount = IG_image_bits_per_channel_get(hImage, &BitsPerChannel);
hPix = IG_pixel_create(ChannelCount, BitsPerChannel);
/* Pixel is created using same attributes as image */
IG_pixel_delete(hPix);
IG_image_delete(hImage);

Remarks:

The number of bits per channel is the amount to allocate, and it must be 8, 16, or 32.
