我正在尝试通过reportlab模块以PDF格式编写图像。这非常有效,但每当我尝试插入透明图像时,它都会在PDF页面中变为黑色。任何人都知道如何解决这个问题?
from reportlab.pdfgen.canvas import Canvas
from reportlab.lib.pagesizes import letter
from reportlab.lib.colors import *
from reportlab.lib.units import cm, mm, inch, pica
from reportlab.platypus import SimpleDocTemplate, Table, TableStyle
pdf = Canvas(AnalysisReport.pdf', pagesize = letter)
pdf.setFont("Helvetica-Bold", 45)
pdf.setFillColor('#000000')
pdf.drawCentredString(inch *4.25, inch *10.00, "Qualitative Analysis Report")
pdf.drawInlineImage("\Glycaan8_78974.png", 500, 500)
pdf.showPage()
pdf.save()
