hej!
just wondering if anyone had any references to drawing
2bit grayscale images?
i have referred to the "seeinggray" gray article at
the Palm site, however it was not explanatory enough.
currently, my application using 1bit bitmaps, however
i want to use 2bit (to have the gray levels). any ideas,
source code references? demos?
i have checked out <UI/WindowNew.h> and here is the
Bitmap structure:
---
typedef struct {
Word width;
Word height;
Word rowBytes;
BitmapFlagsType flags;
Byte pixelSize; // bits/pixel
Byte version; // version of bitmap. This is vers 1
Word nextDepthOffset; // # of DWords to next BitmapType
// from beginnning of this one
Word reserved [2];
// Byte bits[] // If pixelSize == 1:
// this is the start of the pixels
// If pixelSize >= 2, we have:
// ColorTableType followed by pixels
// In most cases the ColorTableType will
// have 0 entries however and be only 1
// word long.
} BitmapType;
---
i dont recall finding any utilities that generated 2 bit
bitmaps, would this mean we would have to load the
bitmaps into the palm application, then hack the memory
to get 2bit? - this structure even comments out "bits" -
so there is no direct way of accessing the color values
without poking into "unknown" memory.
cheers.
az.
