Can I get Alpha values in openGL that are not premultiplied?

I'm making a game that uses lots of alpha values. We have alpha values in the texture map then on top of that we use a color with varying alpha values to dynamically fade things in and out. In order to dynamically fade things in and out I need to pass glBlendFunc GLSRCALPHA & GLONE_MINUS_SRCALPHA. But since the alpha values in the texture map are premultiplied they display wrong unless I've passed glBlendFunc GL_ONE & GLONE_MINUS_SRCALPHA.
How can I disable my texture maps alpha values being premultiplied?
Thanks

You need to be in the US and have a payment method valid in the US.

I use iPhone 5s and iPad Air to take photos. They download automatically to my iMac. However, I often get dups, triplicates or more on the iMac. How can I stop this and how can I get rid of the extras that are already there?

How did you do that? Do you mean you sync to iTunes that had the ipad library?
The phone with the issue, settings - general - reset - erase all contents and settings - this will wipe the phone clean and then restore from your backup.

I just purchased a mac mini and wondered if it's safe to download the Kobo reader app. can I download things from the internet that are not available in the apple store?

I just purchased a mac mini and wondered if it's safe to download from the internet (such as Kobo) that are not available on the app store. It asked me if I was sure it was safe, so it's got me worried.

If you know the sites are OK, then download away.

How can I get rid of promotional ads that are preventing me from expanding my email folders?

Today for the first time, I am getting two promotion ads that regularly change, on the left side of my screen when I am in email, right where my expanded folders normally appear. I tried "expand" and just get a tiny line at the top of these ads with one or two expanded folders named. How can I get rid of these promotion ads?

How can I get past the error message "Variables are not compatible DMB00"?

Hello,
I'm working in Desktop Intelligence XI and I'm using an Excel data provider and a universe data provider. I've linked the two providers on the common field "Cost_Code". The Excel data provider also has a "Cost_Code_Descr_xls" field so I've created a new variable that makes this description field a detail object associated with the "Cost_Code" dimension. This allows me to use both objects in the report.
Some of the cost codes in my universe data provider are not found in my cost_code Excel provider so I'm trying to create a simple formula to deal with these null values:
= if isnull(<Cost_Code_Descr_xls>) then "Unclassified" else <Cost_Code_Descr_xls>
This is where I get the "Variables are not compatible" error.
Any ideas on how to get around this error?
Thanks!
David

Hi David,
I might have been a bit to quick with just saying that the only thing you needed to do was replacing the object with the variable you created.
The variable is only compatible with 'Cost Code' dimension, but not with any of the other dimensions in the report. Your header probably only contains the 'Cost Code' dimension and as such the formula isn't giving any problems. But your details contain ohter incompatible dimensions.
What you need to do is also create detail variables for the other dimensions and relate those to the 'Cost Code' dimension. Use those newly created detail variables in your report.

Harry

How do i get picture from my iphone that are not in my camera roll to my computer??? pleasee help been fiddling for 4 hours!!!

i have been trying to get photo from my phone onto my new computer because i lost everything. i have got all the photos from my camera roll onto it but i can get the one that i put on there from my old computer. i did try download iexplorer but you have to pay for it in dollars im in the UK. i have noticed to that if i edit few they go into the camera roll after but then how do i delete the orignals. please someone help its really frustrating me!!!!!

The photo sync is one way - computer to iphone. As the photos came from your computer in the first place, then they should still be there and should have been included in your regular backup copy of your computer.
You can e-mail them to yourself. they will not be of the original quality.
The iphone is not a storage/backup device. It simply mirrors the selected content of your computer/cloud service.

If you have an iCloud backup, restore it to your phone as explained here: https://support.apple.com/kb/ph12521. If you have a backup on your computer instead, restore it to your phone by connecting your phone to your computer, opening iTunes and going to File>Devices>Restore from Backup.

How do I handle values in source that are not in "lookup" table?

hi there,
I have 3 tables (all Oracle technology):
1) Source table: CALLS with columns MSISDN, TRANS_DATE, TYPE, COST, DURATION
2) Lookup table: SUBSCRIBERS with columns SUBSCRIBERID, MSISDN, IMSI
3) Target table: FACT_CALLS with columns SUBSCRIBERID (not null), CALLDATE, CALLTYPE, CALLDURATION, CALLCHARGE.
Join between source and lookup table:
NVL(CALLS.MSISDN,0) =SUBSCRIBERS.MSISDN)
Mappings on target:
FACT_CALLS.SUBSCRIBERID --> SUBSCRIBERS.SUBSCRIBERID
FACT_CALLS.CALLDATE --> CALLS.TRANS_DATE
FACT_CALLS.CALLTYPE --> CALLS.TYPE
FACT_CALLS.CALLDURATION --> CALLS.DURATION
FACT_CALLS.CALLCHARGE --> CALLS.CHARGE
I have a dummy value in SUBSCRIBERS with values MSISDN = 0, SUBSCRIBERID = 0 and IMSI = 0, to be used if MSISDN in the source table is null or does not exist in the lookup table.
The NVL on the join takes care of the case when source MSISDN is null and this is working fine i.e. returns 0 for SUBSCRIBERID.
The problem occurs when the source MSISDN does have a value but such a value does not exist in the lookup table, such records are rejected.
How do I implement a solution for this?

hi Guru,
Yes I have 2 source tables and a target.
1) I created a join by dragging MSISDN on CALLS to MSISDN on SUBSCRIBERS then added the NVL part to have NVL(CALLS.MSISDN,0) =SUBSCRIBERS.MSISDN)
2) the target does not have MSISDN. Using the join the target SUBSCRIBERID column gets populated with the correct value from the lookup table.
i.e. FACT_CALLS.SUBSCRIBERID = (select SUBSCRIBERID from SUBSCRIBERS where SUBSCRIBERS.MSISDN = CALLS.MSISDN)

HELP !! how can I restore missing photo stream photos that are not in camera roll ?!

HT204266 Is there a way to stop getting updates ie APOS that are not applicable to 1st Add. iPod?

I get numerous app update requests that are not applicable to the 1st IPAD. Is there a way to eliminate these notices? Or a way to upload only those that do apply without doing each one individually? Can I somehow delete the updates I don't want to keep reappearing?
Thanks for any assistance.

No. You just have to be careful not to delete the version of the apps are are only compatble with iPad 1. since yu can't redownload them.

How can I get the value of "Warehose" column in a form

How can I get the value of "Warehouse" column in the form below (I mean what table that contain this value):
Production Supervisor >> Batches >> (Button) Material Details >> (Button) Line Allocations
Well, for more clearly! My problem is I must have the Unit Cost of Items, so I've got it in the cm_cmpt_dtl (table), but if I want to, I must create a relation that require 2 filed, they're Item_ID and Whse_Code.
There's no problem with Item_ID, but Whse_Code seem to be the Mission Impossible (hix, I hate that film!!!!)
I wonder if It was right to post this topic here. But anyway I just post my question here, hope I could get some help.

wow, many, many, many.... and many thanks!
Just add a tiny modify to check out the Batch_type
doc_id = (select batch_id from gme_batch_header where batch_no='&batch_number' and batch_type = 0)
Because the batch_no can be duplicated as we also create Batch and Filrm Planned Order.
Many thanks for your support!
P/S: Sorry for my terrible English :P

How can we get the value of the key field in a custom data model using governance API?

Dear Team,
How can we get the value of the key field in a custom data model, to be used for manipulation of the change request fields using governance API?
Any kind of help would be sincerely appreciated.
Thanks & Regards,
Tushar.

Hi Michael,
Thanks for direction. Let me give more context on this as I'm interested to get more details..One of the issue was to read cross entity field values on UI based on user action and set other entity field behaviour...It is similar to what is being posted here.
For ex: Reading MTART from Basic Data UIBB in MM MDG UI and set the field properties in some other custom entities say ZZETEST. This cannot be done using UI BADI as it only supports single entity at a time and not cross entity. So alternatively we found a solution where we can enhance existing PLMB feederclass cl_mdg_bs_mat_feeder_form by reading the model and the entity as needed as it it proved that it supports cross entity UI field behaviours and so business requirements.
This is a workaround for now.
So the question is How do we achive it using governance API for cross entity field behiaviours.?or what is the right way doing this.
Can we do that using governance API and its' methods?
In the Governance API doc you provided below has referring to below external model as part of gevernance API.
The active or inactive data (before or during the derivation or the check) can be read
with the external data model interface IF_USMD_MODEL_EXT with the method READ_CHAR_VALUE and
the corresponding READ_MODE parameter. To avoid unnecessary flushes (derivations), the NO_FLUSH
parameter should b
e set to ‘X’.
Thanks
