We use CR 10 Developer. We have a 20-page report that contains roughly 30 images. Each image appears in two versions in our DB: low-res (cca 500x450 pixels) and hi-res (cca 2000x1800 pixels). We export the report into HTML and PDF formats; the HTML export uses low-res images and the PDF uses hi-res ones.
Our problem is that exporting is very slow: the HTML takes 205 secs and the PDF takes 395 secs (measured on a fast PC). Previously, when we used our own exporting code, HTML took 45 secs and PDF took 145 secs. That is, Crystal is 2.5 to 5 times slower than our own code.
My question is: do you know of any tricks to speed up exporting? Please note that our reports contain a lot of images - they are very important for our users, and their quality must be very good, especially in the PDF. Thus, reducing the image resolution is not an option. Instead, I'm hoping there's a hidden registry setting or sth like that that might help here.
My second question: it seems to me that Crystal's exporting speed very much depends on the resolution of the images in the report. I did an experiment: I used the low-res images for the PDF export, and the exporting time went down to cca 10% of the original!
Does anybody have an idea *why* Crystal is so sensitive to image resolution? (Actually, this observation applies to all export formats, not only PDF.)
