Problems with RBuilder an imaging

rbuser

Okay I am using Report Builder 7.02 under Delphi 7 with pragnaan export
components

1. now and then ( almost everytime ) I get errors when opening forms with
graphics/images and ppstyle causing my delphi to crash

2. What is the best use of pictures A customer of mine want to mail his
invoices and wants his company logo and such on that invoice.

The invoice will be printed as a pdf with the pragnaan components.
However we have some troubles with finding the right picture format. He has
everything in Quark express and can provide me with everything. But what is
best used to keep the quality/size.
We have experimented a bit and it seems that differents dpi result in a
diferent size for pictures.

I would like to have a solution for problem at point 1 and an advice for
point 2

Thanks in advance,

Take a BMP or JPG Picture. If the print er is a black white laser then
grayscale (or colors) would be converted by the printerdriver in monochrome
(means gray will be with more white dots). Therefor you never need the
picture in the physically printerresolution.

You might be good if your picture has 200-300 DPI, means 200-300 pixels per
inch.

if you wont only print a black/white logo (not grayscale) and only special
fonts, then you might get better results to enhance the DPI of your picture.
But use 600 DPI as a max.

Poor outputs when:
If your picture is to small and you resize it to a bigger one in the layout,
you get a poor printout.
Also if your picture is a lot of more in size, then you need, you get also a
poor printout, because the standard windows-api is used to shring the
picture. This means only pixel lines and coloums would be dropped in the
picture. If you shrink your picture in programs like photoshop they use a
slower method "gaus interpolation" and this is always a good result. So if
your grayscale/color picture has more then 300 DPI, then reduce it in a
programm like photoshop.

Okay the problems occurs when loading reports remplates in to the report
designer then everything on that form bugs.

Did you use truecolor BMP?

Well
the errors occurs whenever I try to load a report from file and it errors
from then on. Looks like a bug in the loading sequence in the report
builder.

and did the load report works correct if you have no images in it?
If the error only happens if an image is in the report, then you could mail
me the image. I will try it with my engine.

doesn't matter if there is an image or not.
