Creating images from sets of data.

Hi,

I am looking for a method to port MFC code to QT;

This is the MFC code:

Code:

---

short int   tab = { 0x00FF, 0x00FF, 0x00FF, 0x00FF, 0x00FF, 0x00FF, 0x00FF, 0x00FF };
CBitmap* bitmap;
bitmap -> CreateBitmap(8, 8, 1, 1, tab);

---

I need to create a QBrush from that bitmap.

Thanks for help.

See QImage ctor

Thanks.

Can we cast short int -> uchar* without any error?

uchar is 8b long whereas short int is 16b on 32b machines. Might be different on others, but I suggest you try and see for yourself.

Ok. Thanks all for help.
Here's the final code I have:

Code:

---

/*! Some data*/
QByteArray	array;
		array.resize(18);
		array[0] =0x0089;
		array[1] =0x0044;
		array[2] =0x0010;
		array[3] =0x0022;
		array[4] =0x0094;
		array[5] =0x0002;
		array[6] =0x0068;
		array[7] =0x0001;
 
		QImage	image(QSize(8,8),QImage::Format_MonoLSB);
		image.loadFromData(array);

---

Now, though, I would like to convert this image: change black pixels -> transparent background, change white-like element to the selected colour.
If you have any idea I would appreciate your help.

Got the answer:

Code:

---

qDebug()<<image.colorTable().size();/*!< "2" -> white & black */
image.setColor(0,Qt::transparent);/*!< Black -> transparent*/
image.setColor(1,qRgb(255,0,0));/*!< White-> red*/

Sorry for bothering you.
