We have discovered that the default rendering mode for reports in WebI is 96 DPI, even though the SDK seems to allow more flexibility than that, so we are wondering if there is some hidden option to cause WebI to render content at a higher DPI.
The specific problem we are having is in regards to some images that render very poorly at 96 DPI in our reports. We can render them at a higher DPI (say 300 DPI for better print quality) and then allow them to be scaled down using the "Stretch" option, but the quality is not nearly as good as our imaging software, and the solution does not work in HTML mode. So that's not an option.
To be honest, I'm surprised about the way things work in this regard, because we should be able to produce high quality images in our reports. 96 DPI is never used for final print quality work. At least InfoView has an option for CrystalReports to render at 120 DPI, but I'm not sure if that only effects the display or not, and if it automatically adjusts offsets that were calculated at 96 DPI when the report was designed.
If we could somehow determine the display mode in a function (e.g., print versus display, or get the DPI, or PDF/HTML/JRP, or something), then we might be able to use a different image (each rendered at a different DPI) depending on the mode. That would be an odd workaround, but if there's no way to change the resolution, this would be great also.
Any suggestions on either front? We need these images to display with at least a "normal" print quality resolution.
