Loss of quality when using QImage for text rendering

Hi,

Our team is rendering text on QImage but found that the text is not legible when used with small font sizes. We observed that rendering directly onto a Widget in the paint event results in much better quality, while using the existing approach of rendering text on to a QImage and then putting that QImage on to the screen, results in visible loss of quality for text. Please see the attached screenshot (TextRenderingIssue_Emulator_wk25.JPG) to understand this issue.

The "Hell World" text on the left side of the screenshot is rendered using QImage, where as the right side "Hello World" text is rendered directly on a widget inside a paint event. Please find attached sample application (TextRenderingOnQImageTestApp.zip file) to reproduce this issue on your side.

Can Qt suggest remedy for this visible loss of quality?

Thanks & Regards,
