Image size display in a report

Question

Hi EVERYONE,
I have a page where user can upload images. I am storing the images in a BLOB field. I can also display images in a report.
Now my question is, how can i reduce the size of the image when I am displaying them. I dont necessarily want to reduce the file size, I just need to display it in smaller size.
Is this possible
Thanks

Hi user585397,
resizing an image can be done with styling information. Depends on how you render the images on the screen. But let's have a look at the sample application, page with products shows the images. the query for this is:
select p.product_id edit_product
, p.product_id view_product_id
, p.product_name
, p.product_description
, p.category
, p.product_avail
, p.list_price
, '<img src="p?n=' || nvl(i.file_object_id,0) || '" height="50" width="50" />' img
from demo_product_info p
, demo_images i
where p.image_id = i.image_id (+)
Here an html-image-tag is created, specifing the heigth and width for displaying the image. This would be one way of doing so.
another way is like on page 6 of sample application, where the html expression for column formatting is used for displaying an iamge (report region, column image_name)
<div style="text-align:center;">
<img src="p?n=#FILE_OBJECT_ID#" height="50" width="50" />
</div>
Hope this helps a bit
