 | Hi,
I had not absolutely to, but because of the large demand make I it still. here The Description, how to make a ByteArray (created with InitExtFX()) manually manipulating can. one ought to but exactly know, what power, because one versehentliches write in incorrect Speicherbereiche substantial damage cause can.
therefore take I these Info not The guide with on, who but thereafter seek, can here in this Forum fündig go...
InitExtFX() commit you a Zeiger. it shows on a structure (BITMAPINFOHEADER), these structure watts though of ProSpeed for a Long-Int extended.
here The Offsets:
0 LONG biSize
4 LONG biWidth, wide the Bildes
8 LONG biHeight, Höhe the Bildes
12 WORD biPlanes, always 1
14 WORD biBitCount, with ProSpeed byte-Arrays always 24 (bit)
16 LONG biCompression, always BI_RGB
20 LONG biSizeImage, Size the byte-Arrays in Bytes
24 LONG biXPelsPerMeter
28 LONG biYPelsPerMeter
32 LONG biClrUsed
36 LONG biClrImportant
40 LONG Zeiger on the memory the byte-Arrays
On The values the structure can of Profan (ex 7) from with Long and @Long zugegriffen go.
on the interessantesten is naturally the Long-Int on Offset 40.
after your the ByteArray manipulating have, can your it with CopyArray() on the screen bring.
Greeting, Frank Abbing |

| Nachtrag:
I had forget, this yet To allude:
an Bitmap becomes in a byte-aray of left under to right supra abgespeichert, dummerweise 8-((.
per Pixel go 3 byte needed, one Blauwert, one Grünwert and a Rotwert. just as is incidentally too one one Bitmapfile aufgebaut.
