[SOLVED] Help in Creating Indexed8 image from a buffer

[xenonforlife]

Hi,

I am having trouble creating image of the format Indexed8 from a buffer that I have defined...my code is as follows:-

@my_buffer= (uchar*)malloc(xy);
for(i=0;i<xy;i++)
my_buffer[i]=(uchar)qrand()%(255);

img= new QImage(my_buffer,x,y,QImage::Format_Indexed8);

for(int i=0;i<256;i++)
{
colors.append());
}

img.setColorTable(colors);
scene = new QGraphicsScene;
img3=img.scaledToWidth(500);
pix=QPixmap::fromImage(img3);
item= new QGraphicsPixmapItem(pix);
scene->addItem(item);
view=new QGraphicsView(scene);
view->show();@

When I execute this piece of code I can just see a black image. Can someone please help me out what am I doing wrong? here colors is a QVector.

hit the edit link on the right of it and add the @-tags, that adds formatting to your code.

I have updated the code so that it is more readable...I hope someone can help me!!

If you had removed the whitespace on the beginning of the lines it would be even more readable...
