Hello,
I have this pdf http://www.borger.com.br/softsupply/demo.pdf and the rendering I get from Quick is much worse than adobe, I am using RenderPage toFile and I have tried different resolutions (100,200,300,600) and also file types (bmp,jpg,png). look at http://www.borger.com.br/softsupply\page1.png Is there something I could do to improve image quality ? thanks and regards, Edgar |

Hi Edgar!
Please keep in mind that QP comes along with a small dll and if we're speaking from the adobe reader we're speaking from a 100-mb-installation ;-) With his big installation adobe can make a sh... made pdf looking very nice - QP can't do this. Do you have this case if you're using a new pdf engine for pdf-creation, too? ... I've seen that the pdf was made with the old Haru-Lib... Cheers, Ingo Edited by Ingo - 29 Apr 09 at 4:22PM |

Hi Ingo,
thanks, but yes I have bad results with pdf produced by other products like WPCubed as well, the looks is very simillar to what I get from sumatra, so I supose you must be using popler as well..... I can send you some samples if you want. I have a very simple one produced with itext with text only, no images, and that looks ok. regards, Edgar |

Perhaps you should consider rendering directly on a device context using RenderPageToDc function.

Hi Edgar!
I think i've found something for you ... Cheers, Ingo function "SetPrecision" Description Use this function to set the precision of numerical values stored in the PDF document. Setting the precision to a lower number will reduce the size of the generated file, while a higher precision will result in a larger file, although objects and graphics will be more accurately positioned. The default precision is 4 |

Hi Ingo,
sorry, but no. I tried with 8 and got the same result, the problem is not in graphics, but in plain text, in my example (there are other cases) I have a simple text in font Courier New Bold, size 20 and the letters are one on top of the other, have a look at the png and you will see. thanks anyhow, Edgar |
