Arguments

srcx

  

X starting point in the source rectangle

srcy

  

Y starting point in the source rectangle

srcmod

  

The number of bytes per row in the source rectangle.

destx

  

X starting point in the RastPort

desty

  

Y starting point in the RastPort

srcformat

  

pixel format in the source rectangle. Currently supported formats are: RECTFMT_RGB, RECTFMT_RGBA, RECTFMT_ARGB, RECTFMT_LUT8, RECTFMT_GREY8

Function result

number of pixels plotted

Description

write the color value of a rectangular array of pixels starting at a specified x,y location and continuing through to another x,y location within a certain RastPort

For each pixel in a rectangular region, write the color value from a linear array of color values into the bitmap used to describe a particular rastport.

Attention

Only RECTFMT_LUT8 can be used on screen depths <= 8 bits. For > 8 bit rastport RECTFMT_LUT8 uses the actual colormap "attached" to the bitmap. If the bitmap is a friend bitmap of a screen bitmap or the screen bitmap itself, it uses the screen's viewport colormap.
