Represents the pitch (in bytes down to the next scanline) of the image buffer of the main image (a 32-bpp bitmap containing color and mask (opacity) information).
This property is there to provide a means of direct access to the image buffer for plugins etc.
Assuming that tjsuint32 is a 32-bit integer type and tjsuint8 is an 8-bit (1byte) integer type, the pointer to the image position (x, y) can be calculated as follows when written in C language.
((tjsuint32 *) ((tjsuint8 *) mainImageBuffer + y * mainImageBufferPitch)) + x
Note that this property returns the number of bytes, not the number of pixels until the next scanline.
This number may be slightly larger than the exact number of bytes required for the width of the image.
Note that this property can have a negative value.
