CreateBitmap method (ILEADRaster)
|
short CreateBitmap (float fWidth, float fHeight, short iBitsPerPixel); | |
|
Overview |
Refer to Copying and Creating Bitmaps. |
Remarks
Initializes and allocates the bitmap, without loading any data.
If you specify 8 bits per pixel or less, the bitmap is created with LEAD's fixed palette. If you specify 0 bits per pixel, for grayscale, the bitmap is created as an 8-bit image with a grayscale palette. If you need to change the palette, refer to the ColorRes method.
Some image processing functions, such as the Rotate method and the ColorRes method need to re-allocate the image data. If you create a bitmap and pass it to these methods, they will change the bitmap to TYPE_CONV and re-allocate memory. So if you set your data using the SetBitmapDataPointer method it will no longer be used.
