HI. I'm again. I have i question about the plotting and saving images using
another qtimer. I would like to save images in the same time that plotting
the spectrograms. Actually, I save the images using this:
def saveFig(self):
fname1 =
"/home/oyuki/Downloads/spectro_Real_time/audios/mic1/result_%s.png"%time.strftime("%H:%M:%S",
gmtime())
self.exporter1 = pg.exporters.ImageExporter(self.imageItems[0])
self.exporter2 = pg.exporters.ImageExporter(self.imageItems[1])
self.exporter3 = pg.exporters.ImageExporter(self.imageItems[2])
self.exporter4 = pg.exporters.ImageExporter(self.imageItems[3])
self.exporter5 = pg.exporters.ImageExporter(self.imageItems[4])
self.exporter6 = pg.exporters.ImageExporter(self.imageItems[5])
self.exporter7 = pg.exporters.ImageExporter(self.imageItems[6])
self.exporter8 = pg.exporters.ImageExporter(self.imageItems[7])
self.exporter =
[self.exporter1,self.exporter2,self.exporter3,self.exporter4,self.exporter5,self.exporter6,self.exporter7,self.exporter8]
for i in range(len(self.pItems)):
self.exporter[i].params.param('width').setValue(304,
blockSignal=self.exporter[i].widthChanged)
self.exporter[i].params.param('height').setValue(163,
blockSignal=self.exporter[i].heightChanged)
self.exporter[0].export(fname1)
