Hi,
I am using Magick++ with QT and having a few problems. The most
important of them is being it too slow. I display the images on
QGraphicsView or QLabel and for this purpose I need to convert image to
QPixmap and vice versa. This particular feature specially while writing
image to Blob is too slow (Some times takes more than one and half
second). Can someone point any useful information to solve this problem?
Following is the snippet of code which I use to convert image to pixmap
and vice versa:
void ITMagickGraphic::convertImageToPixmap()
{
Blob imageBlob;
image.magick("XPM");
image.write(&imageBlob);
const QByteArray imageData((char*)(imageBlob.data()),
imageBlob.length());
pixmapGraphic.loadFromData(imageData);
}
void ITMagickGraphic::convertPixmapToImage()
{
QByteArray newImageData;
QBuffer imageBuffer(&newImageData);
imageBuffer.open(QIODevice::WriteOnly);
pixmapGraphic.save(&imageBuffer,"JPEG");
Blob newImageBlob(newImageData.data(),newImageData.size());
Image
newImage(newImageBlob,Geometry(pixmapGraphic.width(),pixmapGraphic.height()),"jpeg");
image = newImage;
}
Thanks in advance,
Manoj
