 Pointer to pixel data.
gxi32 simage
 Size of an image area in bytes (allocated space = ysize*sline).
gxi32 format
 Pixel format (see GX_PIXELFORMATS).
gxi32 xsize
 Horizontal size of the image in pixels.
gxi32 ysize
 Vertical size of the image in pixels.
gxi32 sline

Field Documentation

gxi32 gxid

Structure identifier.

gxi32 ref

Reference counter.

void* image

Pointer to pixel data.

gxi32 xsize

Horizontal size of the image in pixels.

gxi32 ysize

Vertical size of the image in pixels.

gxi32 sline

Size of a row in bytes.

gxi32 xres

Horizontal resolution.

On a free air camera system such as number plate or face capturing this value is related to a PAL or NTSC image in percentage.
For example:
  • in case of PAL image 768 pixel = 100 %, 384 pixel = 50 %
  • in case of NTSC image 640 pixel = 100 %, 320 pixel = 50 %
On a fixed object windowed camera system like document capturing this value is definied in pixel-per-meter (for example 300 DPI = 11811 pix/m).
(0 value = not defined)

gxi32 yres

Vertical resolution.

On a free air camera system such as number plate or face capturing this value is related to a PAL or NTSC image in percentage.
For example:
  • in case of PAL image 576 pixel = 100 %, 288 pixel = 50 %
  • in case of NTSC image 480 pixel = 100 %, 240 pixel = 50 %
On a fixed object windowed camera system like document capturing this value is definied in pixel-per-meter (for example 300 DPI = 11811 pix/m).
(0 value = not defined)
