3.1.16.1 Write Parameters

Table 3-25 describes the write parameters.

Table 3-25 Write Parameters
Parameter BytesDescriptionDetails
Byte 1Capture start pixel (LSByte)Referenced to active data and 0-based (such that specifying the capture start pixel to be zero indicates the first active pixel of a line)
Byte 2Capture start pixel (MSByte)
Byte 3Capture start line (LSByte)Referenced to active data and 0-based (such that specifying the capture start line to be zero indicates the first active line of a frame)
Byte 4Capture start line (MSByte)
Byte 5Pixels per line (LSByte)1-based (such that specifying a pixel per line value of 854 indicates 854 pixels to be captured)
Byte 6Pixels per line (MSByte)
Byte 7Lines per frame (LSByte)1-based (such that specifying a lines per frame value of 480 indicates 480 lines to be captured)
Byte 8Lines per frame (MSByte)

This command applies to all sources including test patterns, splash screens, and external sources. Making a change to the source or port does not impact the application of this command.

Cropping is done prior to the scaling function in the display module. As such, the size difference between the crop size and display size determines the amount of scaling needed in both dimensions. The scaling limits are listed in Table 3-26.

Table 3-26 Scaling Limits
Controller ConfigurationMaximum Horizontal Interpolation Scale FactorMaximum Horizontal Decimation Scale FactorMaximum Vertical Interpolation Scale FactorMaximum Vertical Decimation Scale Factor
Single controller (excluding interlaced NTSC/PAL)3.03.03.03.0
Single controller (interlaced NTSC/PAL only)3.03.03.06.0

The scaling limits noted in Table 3-26 may not be possible depending on other factors, such as keystone correction. In this case, the system does what is requested even if this results in a broken image. The user is responsible for providing the appropriate input settings to meet the display needs.

If a crop size parameter exceeds the size of the input image, the input image size minus the capture start pixel/line is used (as shown in Figure 3-10). The crop size parameters returned by the read image crop command are always the values specified by the Write Image Crop command.
