IG_ISIS_TAG_PLANARCONFIGURATION
How the components of an RGB image are arranged. 0x011C ∙ 284
IG_ISIS_TAG_PLANARCONFIGURATION describes how data in a color RGB image is arranged. This arrangements is often determined by whether you are dealing with a one-pass or three-pas color scanner.

Drivers for scanners that output color image data, PIXFPACK.
| 1 | IG_ISIS_PLANARCONFIG_LINE or IG_ISIS_PLANARCONFIG_LINE_ PACK | Line pack. Color data for each pixel is stored in order by line:RGBRGBRGBRGBRGBRGB... RGBEach RGB set represents one pixel of a line. Each line is padded to an even byte boundary. This is probably the easiest format to handle because the data for each pixel is in one place. Supported in TIFF. |
| 2 | IG_ISIS_PLANARCONFIG_PAGE | Page. Color data for the entire page is stored by color plane:RRRRRRRRRRRRRRRRRR... RRRRRRRRRRRRRRRRRRRRR... RRRRRRRRRRRRRRRRRRRRR... RRR .GGGGGGGGGGGGGGGGGG... GGGGGGGGGGGGGGGGGGGGG... GGGGGGGGGGGGGGGGGGGGG... GGG .BBBBBBBBBBBBBBBBBB... BBBBBBBBBBBBBBBBBBBBB... BBBBBBBBBBBBBBBBBBBBB... BBBEach RRR... represents red for the entire page. Each line is padded to an even byte boundary. This is common for 3-pass scanners. Supported in TIFF. |
| 5000 | IG_ISIS_PLANARCONFIG_ LINE_UNPACK | Line Unpack. Color data for each line is stored by color plane:RRRRRRRRRRRRRRRRRR... RRRGGGGGGGGGGGGGGGGGG... GGGBBBBBBBBBBBBBBBBBB... BBBRRRRRRRRRRRRRRRRRR... RRRGGGGGGGGGGGGGGGGGG... GGGEach RRR... set represents red for an entire line. Each line is padded to an even byte boundary. This format is not supported by TIFF, but the toolkit can be made to save TIFF files using this configuration, which can then be read only by this toolkit. Note that PCX 24-bit color requires this format, and many color scanners return data in this format. |
The following tags together define the color format of the image data:
IG_ISIS_TAG_SAMPLESPERPIXEL ∙ IG_ISIS_TAG_BITSPERSAMPLE ∙ IG_ISIS_TAG_PHOTOMETRICINTERPRETATION ∙ IG_ISIS_TAG_COMPRESSION ∙ IG_ISIS_TAG_PLANARCONFIGURATION
IG_ISIS_TAG_PLANARCONFIGURATION is only valid for RGB color images.
