GDAL community,
Is is plausible to contain a RGB image array (as pixel interleaved,
rgbrgbrgbrgb) in a single MEMRasterBand to generate a color file via
GDALCreateCopy()?
My application performs the following sequence:
1. Read a color image into an image buffer in pixel interleaved (rgbrgbrgb)
format.
2. Setup MEM Driver to contain the recently read in image from step 1 above via
AddBand().
3. Call GDALCreateCopy() on the specific output of my desire.
I have a question on Step 2 above (AddBand()). Do I have to create 3 seperate
bands to contain individual color component? That would mean I have to take my
RGB image buffer and seperate it into three new arrays of size (imageWidth *
imageHeight) and call AddBands() on each one.
I am trying to adviod that step as I find it as an extra step. However, I
understand if I have to because for a given color image GDAL always represents
the file with 3 or 4 bands.
My answer is I will probably have to. My application can write out a valid
file, but the resulting file is in Greyscale.
