Rendering 3D Text

Hi,
Just a quick question - what does Photoshop CS6 Extended use to render 3D objects? When I create very simple 3D text and render, it's taking about 2 hours or more. In the past (5 or so years ago) I did a lot of computer animation with Maya, Max etc. and with my less capable system back then, each frame rendered much quicker than it seems to with Photoshop. I understand that for animation I was only rendering 1920 x 1080 images rather than my current A4 300dpi ones, but should it really make that much difference? It seems to perform many many render passes before it's done. My graphics card is definitely the weakest part of my system...I built this computer not too long ago for use with CS3 and now it's all about graphics card performance...typical!
Here are my specs:
Windows 7 64 bit
Intel i5 2500k @ 3.3ghz
16gb DDR3 ram
Nvidia GT220 (512mb DDR3)
Would a 1gb DDR5 card speed up rendering that dramatically? I was always under the impression it was CPU that determined render speed?
Thanks,
Chris

Photoshop uses our own Adobe Ray Tracer engine.
Rendering time is based on all kinds of input > Lights, materials, transparency, refraction, PS document size, it all adds up to longer render times. If you are not printing your document there is no reason to be at 300dpi. 3D Max, Maya et al do not render documnet's of this size (eg 300ppi) so yes that makes a HUGE difference.
Try to do a comparable test 1920 x 1080 and use 72dpi docs in Ps. I have seen Mental Ray deliver similar timed results. For good or bad, I think good, we make a lot of assumptions for you with our Adobe Ray Tracer so you dont have to turn all those knobs, like in Mental Ray.
The Ray Trace does not use your Graphics Card, yes, it's all about CPU cores for this Ray Tracer.
I hope that helps,

PDF in browser rendered as Text

We're trying to render SMARTFORMS outpur as PDF within our WebDynpro
application. We've found several posts which have been very helpful
and I think we're close. When we try to show the pdf a client browser window
is spawned and the content is rendered as text within the browser (shown below).
It looks like I'm not setting the content-type in the response header correctly.
Below is the code we're using.
Much Thanks,
Greg
/* Code used to launch browser and view PDF */
String file_prefix = "rfq";
   IWDCachedWebResource pdfResource = WDWebResource.getPublicCachedWebResource(
                  pdfContent, WDWebResourceType.PDF, WDScopeType.CLIENTSESSION_SCOPE,
                  wdThis.wdGetAPI().getComponent().getDeployableObjectPart(),
                  file_prefix );
   wdComponentAPI.getWindowManager().createExternalWindow( pdfResource.getURL(), "RFQ", false).open();

Hi,
Create a separate view to display PDF.
Create a frame on that view and attach its datasource to url.
Please go through the following code.
The return value URL should be used as source for Frame.
private String convertXstringToUrl( byte[] doc_content, java.lang.String doc_type ) {
          // setIFrameUrl()
       String url = "";
       if (doc_content != null && doc_content.length != 0) {
            MessageManager msgMgr;
            WDWebResourceType webResType = WDWebResourceType.PDF;
            if (doc_type.equals("PDF")) {
                 webResType = WDWebResourceType.PDF;
               } else if (doc_type.equals("HTML")){
                 webResType = WDWebResourceType.HTML;
            } else if (doc_type.equals("XML")) {
                 webResType = WDWebResourceType.XML;
            } else {
              try {

              } catch(FPMRuntimeException ex) {
            IWDWebResource webResource = WDWebResource.getWebResource(doc_content, webResType);
//            IWDWebResource webResource = WDWebResource.getWebResource(doc_content, webResType, false);
            try {
                 url = webResource.getURL();
            catch (WDURLException ex) {
                 try {
                      fpm.getMessageManager().raiseException(wdThis.wdGetAPI().getComponent(), ex);

Safari rendering default text with condensed font?

Has anyone else experienced this in the last few days?
All of a sudden Safari is rendering default text with a different font, a light, condensed one.
The side-by-side shows the Wordpress Admin menu on my Macbook & on my iMac.
The Macbook is still rendering as always, the iMac now has this new font.
Aside from within the Wordpress Admin area, I'm seeing the same thing in various other places you'd expect to see a default font, for default text.
It's not the end of the world but considering I haven't done anything to cause the change I'm concerned it's something malicious causing it,
any insights anyone?
Thanks in advance.

Installled any third party fonts lately?
And check for duplicate fonts.
Open the Font Book in your Applications folder.
From the Font Book menu bar click Edit > Look for Enabled Duplicates

Text Problem - 'Editing or Rendering the text layer will cause the layout to change'

Hello all,
The problem I'm having is that when I try to edit a text layer, the layout of the layer changes completely - I have a grey warning triangle in the affected layer thumbnail that states the following message when I hover over it :
'Font is present on system but requires a layout change'
When I double click to edit the text layer, the following warning dialog pops up:
'Editing or Rendering the text layer will cause the layout to change'
I'm forced to click 'okay' to proceed which is when the layout of the text layer changes completely! Obviously this has massive implications for branding and page consitency!!
Now even if I have to do this the long way round, which means rebuilding each individual text layer for every single document, there is another problem, it appears that after I click 'OK' photoshop distorts the text! This means that I can't increase or decrease the font size to match it up! Same font, Same height, same AA, same weight, different circle radius!
Any help is massively appreciated,
I'm using CS5 64bit Cloud edition on Windows 7, I've already tried updating and reinstalling Photoshop but it doesnt remedy the problem, I've reinstalled a sample batch of the fonts affected and deleted any plugins
GULP!

That warning is pretty clear - you don't appear to have the font on your system. Not sure what otehr answer you are looking for. The layout changes beyond that could be indicative of a million things like the original source layers having been heavily customized with manual kerning, used a different version of a seemingly similar font, have been created with glyph substitution on a system with a different language and whatever... Unless you mean you created the files yourself just yesterday and the warning appears despite nothing have changed, everything works as intended. If you think something is up, you need to provide more info.

Acrobat renders embedded text unsearchable by spreading out letters: why?

Something strange happened today when I created a single PDF page of a magazine and inserted it into the larger PDF of the entire magazine: all the letters in the words embedded in the single PDF page were automatically spread out, so this caption, in the single PDF page:
the commodore just faintly heard the words
HE WAS NOT MEANT TO HEAR”
appeared this way, on that same page within the larger PDF document:
t h e c o m m o d o r e j u s t f a i n t l y h e a r d t h e w o r d s
HE WA S NOT ME A N T TO H E A R ”
with white space inserted between most of the letters. This change effectively renders the text unsearchable, since no one is going to insert a space between letters when searching for words in the pdf.
Does anyone know why this happens? And is there any way of preventing it? If it helps, this spreading out of letters seems to happen more often in headers and captions than in columns of text. Thanks!

Not sure, but were the fonts embedded. It looks like a font issue. You might also try scrolling through the text to see if the spaces are really there.

What causes selectOneChoice to be rendered as text instead of drop down?

I notice that my UIInput components are being rendered as HTML text rather than their normal HTML tags when I specify a value in EL. For example, the selectOneChoice component is rendered as:
&lt!-- Start: oracle.adf.SelectOne["ruleSelection"] --&gt&ltspan id="form1:ruleSelection" class="x6"&gtCredit Okay&lt/span&gt
so I can't see the drop down arrow or box or any of the other options since it doesn't use the normal HTML select tag.
The source is below:
Except from jsp page
<af:selectOneChoice binding="#{testRuleSetBackingBean.ruleSelection}"
id="ruleSelection" value="#{testRuleSetBackingBean.rows[0].rule}">
<f:selectItems value="#{testRuleSetBackingBean.ruleNames}"
binding="#{testRuleSetBackingBean.ruleItem}" id="ruleItem"/>
</af:selectOneChoice>
However if I remove the value attribute from ruleSelection then it renders as expected, with a drop down box with all the items in.
More source below:
Excerpt from backing bean:
private RuleCondition[] rows;
//bindings for ruleSelection
public void setRuleSelection(CoreSelectOneChoice selectOneMenu1) {
this.ruleSelection = selectOneMenu1;
public CoreSelectOneChoice getRuleSelection() {
return ruleSelection;
//bindings for ruleItem
public void setRuleItem(UISelectItems selectItems1) {
this.ruleItem = selectItems1;
public UISelectItems getRuleItem() {
return ruleItem;
// items in the list are names of rules
public ArrayList<SelectItem> getRuleNames(){
//... just returns an array list of javax.faces.model.SelectItem
//with each SelectItem containing a value and label that are String objects
Except from RuleCondition.java
private Rule rule;
public Rule getRule(){
return rule;
public String toString(){
     return this.getClass().getName();
// equals overriden so that we can equate a String object and a Rule object
// if the String equals the class name of the Rule
public boolean equals(Object obj){
          if (obj instanceof String){
               if (this.getClass().getName().equals(obj)){
                    return true;
               }else {
                    return false;
          }else if(this.getClass().getName().equals(obj.getClass().getName())){
               return true;
          }else {
               return false;

Using ADF Faces implementation 10_1_3_0_4
Using MyFaces 1.1.3 (same results with 1.1.1)
Turning debug-output on in adf-faces-config.xml produced nothing
Any hints on what may cause this behaviour?

Minutes after posting this I determined the answer - lack of setters. I added:
RuleCondition.getRule(.....)
TestRuleSetBackingBean.setRuleNames(....)
and hey, presto - I can now see the drop down.
This makes perfect sense to me now - it was determining this as a read-only property. Nice.

SSRS web based report viewer control rendering issues - text getting clipped chopped off

Hi,
I am using web based SSRS report viewer control to display SSRS reports in browsers like Chrome, FF, IE, Safari etc. My issue is some text is getting chopped off (clipped) in all cells of some reports. I investigated on my end by analyzing generated HTML
and I could see a problem in the HTML that report viewer control is generating. But I am afraid to apply any HTML or Javascript hacks at the moment considering we have hundreds of reports.
You can see in above image how text got chopped off. The problem in HTML (given below) is the text has been wrapped in a div tag with a fixed height. If I remove the height and also padding on parent TD, the text appears properly.
<td class="A23dfe7c5f99245f2a0db522a22a6035597c" style="HEIGHT:5.00mm;background-color:#d3d3d3;"><div style="HEIGHT:3.24mm;overflow:hidden;"><table lang="en-US" cellspacing="0"
cellpadding="0" border="0" class="Pd9776e5f7eaf4df696265b8b49d1da39_1_r17"><tbody><tr><td class="A23dfe7c5f99245f2a0db522a22a6035597" style="word-wrap:break-word;white-space:pre-wrap;">MyType11</td></tr></tbody></table></div></td>
Please let me know if you have faced a similar scenario before.
Here is link to stackoverflow thread -

Hi Murtaza,
According to your description, when you display the report with Report Viewer control, the data within the text is cutoff.
Based on my research, the issue could cause by that Arial Unicode MS font hasn’t been installed on the server where Reporting Services run. Besides, when we use ReportViewer control to render report, we’d better set
AsyncRendering="true" in the Report Viewer control. Also please run the IE with compatibility mode. For more information, please refer to similar threads below:

PDFMaker: Extra chars being rendered in text fields

I've used PDFMaker (Adobe Acrobat 9 Professional) to render a PDF from a Microsoft Word document. However, the PDF contains extra characters; specifically, characters are added to any fields referencing headings in the document.
In the following screen capture, you can see an example:
http://img510.imageshack.us/my.php?image=extracharactersinfieldstl8.jpg
The page header should read "Introduction * Introduction". These aren't static text, but text fields that reference headings. However, Acrobat has introduced the extra characters "1B" and "19B".
I've checked, and the headings that the field references are actually rendered correctly (one heading - Introduction - is shown on the screen capture itself).
Regards,
Paul.

Displaying rendered HTML text in spry detail region

Hi,
I have just started to play around with DW CS3 & spry and
love them!
I have a Master/Detail spry going from my database, but am
having a problem displaying the detail the way I need it. The mySQL
field is a BLOB for some HTML formatted text (I get the text
elsewhere using a Xinha textarea edit widget and load the the
formatted HTML text into my db). For example, my string is
"<h2>this test</h2><strong>xyz</strong>"
which is loaded into my db. I am using the dreamweaver ADDT export
XML functionality to generate my spry master/detail region.
My detail region is displaying the correct html associated
with the selected master table entry, but it's with the HTML tags,
not rendered as HTML (I don't want to see
<h2>title</h2>; I'd like to see title with <H2>
formatting).
It's much like what I think a RSS feed would be, but can't
find a way just to get the html to render because I don't have the
files externally to source an iframe or anything. (I tried a XLS
fragment transformation, just putting the detail record field that
I want in an XLS file, but that didn't do anything).
Any kind of guidance, hint, point and laugh but then tell me,
would be greatly appreciated. I also posted at first at ADDT and
then General Dreamweaver because I didn't locate this forum in the
Forum topic list, so when I did find this I thought this is
obviously where I should have first posted - sorry if anyone has
also been surfing around. Thanks so much so any info.

Hi Don,
Thanks so much for responding. I actually did do that, but it
seems like I might be doing it in the wrong place. I tried it in
the .js that I have in my header:
var dsList = new Spry.Data.XMLDataSet("./export.php",
"theSpecials/special",{sortOnLoad:"rating",sortOrderOnLoad:"ascending",distinctOnLoad:tru e});
dsList.setColumnType("detail", "html");
which didn't do it. I also tried it right in my detail
display area:
<div style="overflow:hidden; width: 400px;"
spry:detailregion="dsList">
<div> 
<div id="detailDisplay" style="width:380px; "> 
<script
type="text/javascript">dsList.setColumnType("detail","html");</script>{dsList::detail}

</div> 
</div> 

</div>
Excuse the inline ugliness, will clean it up when it's
functional. But that doesn't seem to do it either. I am storing
that particular field as a blob in the mysql database, but I
already tried making that a VARCHAR which had no effect either.
Thanks so much for for the suggestion! Any other gems that I
can try?
Liz

Firefox not rendering italic text

I can't pinpoint specifically when this began, but this is an issue I've only seen after doing a fresh install of Ubuntu 11.04. Firefox isn't rendering text that appears between <i> and <cite> tags (there may be others that would render as italicized text by default, but I haven't checked), but is correctly rendering text between <em> tags. The text is literally just gone but is taking up space in the layout.
Chrome on the same machine isn't having the same problem

It seem that in the latest versions of (k)ubuntu only ttf-dejavu-core is installed by default. If you install ttf-dejavu-extra [ sudo apt-get install ttf-dejavu-extra ] that fixes the problem for me

Safari Rendering Site Text Poorly

Hello- Thanks in advance for your thoughts.
I've created a site (in RapidWeaver) and lately, Safari is rending the text pretty poorly. I don't know if its the font I'm using or if its Safari. Looks nicer in Windows 7 and Firefox (can't believe I'm saying that).
Any thoughts? Is it OS X, Safari or Fonts I'm using?
Thanks for the help.
http://www.simdevgroup.com

Mr. Bill--
If the site in question is on the link you gave, it read fine on my MacBook. It might be Safari, but having had some website building experience (and enough HTML to be considered dangerous), my guess is that it's your font. Keeping in mind that Arial, Time New Roman, and (for some bizarre reason) Courier are considered "standard" and renderable on all computers--and anything else may/may not be iffy--is why I'm thinking font.
OSX shouldn't be your culprit; the OS should have no bearing on what something looks like per se. It --might--be Safari...but like I said: the site in question is on the link you gave, it looked okay to me.
Hope this helps--

Conditionally rendering of text

Hi,
In the DB, I've got a table containing a field called 'value' that is "0" or "1".
On a JSF page, I have a button to change this value from 0 to 1, or from 1 to 0 in the DB.
Below that button, I want a text displaying :
"The application is Running" if the value in the DB is set to 1,
"The application is Stopped" if the value in the DB is set to 0.
I can manage this by setting the Rendered field to a condition,
but what condition?
What I have done so far :
I created a method in AM called 'isRunning' that returns true or false.
So I thought I could set the Rendered field to : #{bindings.isRunning.execute}
but that's not working.
Any hints ?

I created a getStatus() method in AM that returns the string 'running' or 'not running'.
But I'm don't know how to call this method.
Normally it should be in #{bindings.getStatus} , but it's not there ?
It's a show detail header component that must display : This application is running / not running.

Customize rendering the Text Caption of the Header/DefaultSingleColumn

in OAF R12 (Swan), The pagelayout region renders its title with a text and a horizontal line. I want the Header or DefaultSingleColumn(or DoubleColumn) region to render similarly as the pageLayout region.
What css selectors do i need to specify?
thanks,
Anthony

Hi,
In processrequest you can set the text property of Header and defaultsingle colukn region.
import oracle.apps.fnd.framework.webui.beans.layout.OAHeaderBean;
import oracle.apps.fnd.framework.webui.beans.layout.OADefaultSingleColumnBean;
OAHeaderBean bean = (OAHeaderBean)webBean.findindexedchildrecursive("<id of header region>");
bean.setText("Header region");
Similarly for DefaultSingleColumn
OADefaultSingleColumnBean bean2 = (OADefaultSingleColumnBean)webBean.findindexedchildrecursive("<id>");
bean2.setText("Default region");
Thanks,
Gaurav

IE8 Rendering Standard Text Fonts Bold?

I am currenty designing an XHTML page in Dreamweaver CS4 and have tried various standard fonts (Times New Roman, Courier, Georgia etc.) and whichever I chose the font renders absolutely perfect (as in design view) on Firefox, Google Chrome, Opera and Safari but renders BOLD in IE8. I have clearly defined the text family, size, style, variant and weight in CCS rules for the body tag and p tag and have even created a seperate class for the text but it still renders bold in IE8. I also tried to do a CSS reset but that didnt alter anything. Is there anyway around this or are my IE8 visitors just going to have to put up with bold text?

And being a little bit contrary - the font looks the same to me viewing in Firefox and using IETester IE8.
Just a side note:
I might add, that the H1 (About Us) is very difficult to read on my laptop.. seems to blend into the black background. Need to be lightened up a bit I believe.
The blue text (whether it is normal font weight or bold) is also very difficult to read on the black background - causing a bit of an accessibility issue. (My eyes are probably older than most here :-) I don't usually have problems reading up close to the monitor, but that blue is very hard on the eyes).

Subpixel rendering of text

The current options to render text (sharp, crisp, etc) are not good enough.
Many UI designers work with fonts between 9-13px. Photoshop's text rendering engine needs an option for subpixel rendering much the same way browers handing text and Flash TLF. This process introduces color artifacts but the results are sharper, more legible text.

Do you mean color filter antialiasing? (all antialiasing is subpixel)
We can't do that (nor can any image editor that knows what they're doing). Color filter antialiasing only works for final output -- when you know what's being the text, and what display the text is on, what orientation it's being shown at, etc. That's one reason why the OS makers are dropping color filter antialiasing: it doesn't work well for portable devices, arbitrary displays, new display technologies, composited views, etc.
And Photoshop CS6's text rendering is much closer to OS and browser rendering without trying to be bug compatible with every minor OS and browser version (yeah, they change text rendering that often).
