PIL saves as a 24-bit true-color bitmap

Question

Hi guys, I have a png file created by Gnuplot that I need to put in an excel document using XLWT.

XLWT cannot import PNG into a document, only BMP, so I need to convert PNG first. I used PIL for this.

Here is the relevant code:

im = Image.open('%s' % os.path.join(os.getcwd(), s + '.png')) im.save('%s.bmp' % s) 

However, XLWT gives me this error:

 Exception: bitmap isn't a 24bit true color bitmap. 

Here is what the XLWT code looks like:

 self.chart.insert_bitmap(path, 2, 2) 

I know that both images work fine, they open with windows. I also tried adding a pause of 2 seconds after creating the BMP (to compensate for the recording time), but it still doesn't work.

How do I make a 24-bit bitmap with true color using PIL?

Answer 1

Nevermind! I just realized it myself.

Edit

 im = Image.open('%s' % os.path.join(os.getcwd(), s + '.png')) 

For

 im = Image.open('%s' % os.path.join(os.getcwd(), s + '.png')).convert("RGB")
