How to change image resolution in oracle forms.

Hi Experts,
I am working on oracle forms 10g (Windows7 OS). Can we get the image resolution of an image item in oracle forms? Can we resize the image in terms of resolution?
I have a requirement where user can upload only 1280x720 size images. Either i have to validate the image resolution and give them a message saying 'Only 1280x720 size images are allowed' or simply i have to convert the image to be upload to 1280x720 size and save in the database. If someone could give the solution for the above problem that would be very much appreciated.
Thanks,
Pramod SR

1. You need to resample.
2. You can automate the process.
1.
Open one of the images.
Go to Image > Image Size
Set the units to Percent (100)
Change the resolution to 300 ppi (not cm!)
Make sure Resample is checked
2. automation
Test the above steps to make sure it works.
Record the steps as an action.
Make a droplet from the action.
Drag the folder with the images to the droplet.

  • How to store image in the oracle database 10.2. using File Maker 10.

    Hi.,
    I want to store image, media file in the oracle database using File Maker as a front end.
    I connect Oracle using odbc from file maker. There are table and in that table there a column "pict" of blob type. but this column is not showing in the file maker.
    2. Here I can not change the data type of any column.
    Now how to store images in the oracle table using odbc or any other tool.
    Regards,

    I wrote an example for my students, you can find it here. It's using PHP as the front end but all you need to do is know how and leverage the stored procedures. All code is downloadable in zip files from the blog.

  • How to change images based on action.Even clicking changed images should ?

    how to change images based on action.
    Even clicking changed images should do respective actions.
    and while displaying only one image at a time sholud get displayed.
    I am using three images for a single column of a table in Jsp.
    Any clues.
    Any link for any good javascript html jsp site where i can find some good solution.

    In broad way if i say i have multiple situations in mutiple tables where i need such a logic to operate in for all tables.
    lets say in first time load of page by default one image will be displayed (one with sorted order for first column rest all non sorted)Now after every click to any image respective sort should get called.along with all images should get changed.Here with every function one/two images will get effect at least.
    As in first if i say sort by desc then this image will change rest all will remain in unsort form.
    when i move to other column and click on new image the previos will convert to unsort and new one will convert to sort by ascending. rest all will be in unsort form as it is.
    Now it seems like same logic is required with two three conditions.
    even for everyaction different parametrs has to be passed at differnt situations.
    Any good idea if someone can suggest.
    I will be very greatful for him.
    thanks

  • How can I code this in Oracle Forms?

    I have a master-detail form. In the detail block, I have several records. Here is my name table.
    ID Name_Type Name
    1 old Mike
    2 Current John
    3 old Peter
    4 old Andrew
    I would like to create a button trigger which shall perform the following:
    1) insert a record into database with a copy of current value. In the above case it will insert create a record for John as name_type = 'OLD'. So we have total of 5 records. Commit the transaction.
    2) Scroll through my detail records (5) and go to one specific record and erase the values from it. In the above case, it should find John's record with name_type = 'Current' and erase John from it.
    How can I accomplish this in Oracle forms using a button-pressed trigger?

    Hi,
    Simple, using current values you can create new id , 'old' and name so oracle will create record, now refresh block, next using next_record in loop you can find record,erase one and refresh block.

  • How to invoke crystal reports from Oracle forms 11g R2 along with passing p

    How to invoke crystal reports from Oracle forms 11g R2 along with passing parameter to it.
    how to pass parameters to crystal report, please help.

    how to pass parameters to crystal report, please help.This would entirely depend on crystal reports and you might find informations on crystal reports related communities more likely...I for one have seen crystal reports the last time about 12 years ago. And even back then I simply acknowledged it's existence instead of working with it.
    Maybe crystal reports can be invoked via a URL call which would make it simple as you'd need simply build an URL and show the report using web.show_document. But that's pure speculation. Also you might not be the first with this requirement, so the solution to your problem might be right under your nose and just a little google search away ;)

    How to change image display of my podcast page in iTunes?

    As far as I understand you need to update the image's link in your RSS XML file.  Be sure to change the link file name even if it links to a different image.
    The XML files associated with podcasts are checked for changes every 24 hours so don't expect this to happen instantly.

    Post relates to: HP TouchPad (WiFi)

    Sorry to say reloading WebOS did not help this issue on my TP. contacted Support and was told to send it.Even sorrier to say that my TP is now lost. My tracking number reports it as delievered on Dec 5, but HP has no record of it.When I got back on Chat they  are now also telling me that my TP serial number is a EU model, even though my box clearly states HP Touchpad ,US, 1.20,32gb,Wifi.
    Not sure what that even has to do with it being lost now..if it is as they say and no warranty on it in US I just want it sent back.
