It is one of the two classes Qt provides for dealing with images, the other being QPixmap. QImage is designed and optimized for I/O and for direct pixel access/manipulation, QPixmap is designed and optimized for drawing. There are (slow) functions to convert between QImage and QPixmp; QPixmap::convertToImage() and QPixmap::convertFromImage(). An image has the parameters width, height and depth (bits per pixel, bpp), a color table and the actual pixels. QImage supports 1-bpp, 8-bpp and 32-bpp image data. 1-bpp and 8-bpp images use a color lookup table; the pixel value is a color table index. 32-bpp images encode an RGB value in 24 bits and ignore the color table. The most significant byte is used for the alpha buffer. An entry in the color table is an RGB triplet encoded as uint. Use the qRed, qGreen and qBlue functions (qcolor.h) to access the components, and qRgb to make an RGB triplet (see Page 2 (printed 9/22/98) QQQQIIIImmmmaaaaggggeeee((((3333qqqqtttt)))) TTTTrrrroooollllllll TTTTeeeecccchhhh AAAASSSS ((((9999 JJJJuuuullllyyyy 1111999999998888)))) QQQQIIIImmmmaaaaggggeeee((((3333qqqqtttt)))) the QColor class documentation). 1-bpp (monochrome) images have a color table with maximum 2 colors. There are two different formats; big endian (MSB first) or little endian (LSB first) bit order. To access a single bit, you will have to do some bitshifts: QImage image; // sets bit at (x,y) to 1 if ( image.bitOrder() == QImage::LittleEndian ) *(image.scanLine(y) + (x >> 3)) |= 1 << (x & 7); else *(image.scanLine(y) + (x >> 3)) |= 1 << (7 -(x & 7)); If this looks complicated, it might be a good idea to convert the 1-bpp image to an 8-bpp image using convertDepth(). 8-bpp images are much easier to work with than 1-bpp images because they have a single byte per pixel: QImage image; // set entry 19 in the color table to yellow image.setColor( 19, qRgb(255,255,0) ); // set 8 bit pixel at (x,y) to value yellow (in color table) *(image.scanLine(y) + x) = 19; 32-bpp images ignore the color table, instead each pixel contains the RGB triplet. 24 bits contain the RGB value and the most significant byte is reserved for the alpha buffer. QImage image; // sets 32 bit pixel at (x,y) to yellow. uint *p = (uint *)image.scanLine(y) + x; *p = qRgb(255,255,0); The scanlines are 32-bit aligned for all depths. The QImage class uses explicit sharing, similar to that of QArray and QString.
