PDF text rendered partly bold was created by flubba

when rendering PDFs sometimes part of the text seems to be rendered bold. This occurs more often when the PDF is zoomed/scaled.
In the attached screenshot the text on the right should look like the one on the left.

The PDF parts are rendered into images using the following code:

Code:

int dib = Global.dibGet(0, (int)patchW, (int)patchH);
float scaleW =  pageW/doc.GetPageWidth(pageNo) ;
Matrix mat = new com.radaee.pdf.Matrix(scaleW, -scaleW,-patchX,pageH-patchY );
page.Render( dib, mat );
int lockBitmap = Global.lockBitmap(bitmap);
Global.drawToBmp(lockBitmap, dib, 0,0);
Global.unlockBitmap(bitmap, lockBitmap);
dib = Global.dibFree(dib);

before page.Render, you should invoke page.RenderPrepare.
for i tested the demo project, and the problem not appears.

Thanks, that's it.

I added page.RenderPrepare(dib) and the problem does not occur anymore.
