• Cannot save a PNG file with alpha channel transparency format

  I try to send a PNG file with transparency channel alpha on my Zenfolio web page. It is a custom application of copyright law that I do.  When I save the file, cs5, and I select Save in PNG, in the window, I get a message error/alert that says "the file should be saved as a copy with this application.  I'm not allowed to select the Alpha channel option.

  I think that I have a setting in CS5 that is making this happen, but I'm not smart enough to understand.

  What happens when I have when even save it and upload this file to my Zenfolio website is copyright logo has a cloud of sorts with it. It's the rest of the House generated page which should be, but is not transparent.

  PNG does not support alpha channels, only one channel of transparency.

  Just make the image with transparency and save in PNG.

• Contact information for return pixel Imaq image with the mouse click event

  Hello

  I'm trying to get the coordinates in pixels of an image Imaq based on a mouse click event, similar to this post and this post. The problem is that with the first post, I get the coordinates in the image control and hesitate to trust them, they seem to have the Center origin, may return negative coordinates and do not represent the actual size of the detector that I use (512 x 512). It also returns the coordinates outside the actual data when it is clicked on the image control framework. The second method returns simply null coordinates. What I want are the coordinates of the pixel displayed when hovering the mouse imaq image control framework.

  What baffles me, is that I tried the second method with a png stock file and it works fine, it is only when I create an image from the data of my camera than the coordinates are returned null. Note data views of camera under control of image very well.

  Any ideas would be useful. Enclosed is a picture of the offending code and the Panel before displaying the camera data is coming (I know it needs some cleaning).

• Sequence of images with alpha to video with transparency

  I have a sequence of png images that has an alpha channel. I care about her as a kind of video where if I import into PowerPoint, I can overlay on a background and have the visible bottom where the video alpha is out.

• OpenGL image with alpha are darker

  Hello

  I launch my game on BB10 (Portage from Android, PC). On PC Android, my game with an alpha images are ok, but on the playbook all alpha are darker. Something escapes me?

  The code to load the texture:

  glTexImage2D (GL_TEXTURE_2D, 0, GL_RGBA, image.getWidth (), image.getHeight (), 0, GL_RGBA, GL_UNSIGNED_BYTE, image.getDatas ());

  Code to render a texture:

  glClearColor ((GLfloat) (gBackColor.r), (GLfloat) (gBackColor.g), (GLfloat) (gBackColor.b), (GLfloat) (gBackColor.a));

  Clear the depth buffer and the screen: Note: no need pay the color buffer car on affcihe all the screen
  glClear(GL_COLOR_BUFFER_BIT |) GL_DEPTH_BUFFER_BIT);
   
  glLoadIdentity();
  glPushMatrix();

  affects lightDiffuse
  lightDiffuse * this =-> mDiffuseColor;
   
  glColor4f ((GLfloat) (lightDiffuse.r), (GLfloat) (lightDiffuse.g), (GLfloat) (lightDiffuse.b), (GLfloat) lightDiffuse.a);

  And finally, I use glDrawArrays (...)

  On PC and Android, I have no problem.

  Thank you

  Found in other post of the thread:

  transparency int = SCREEN_TRANSPARENCY_SOURCE_OVER;

  screen_set_window_property_iv (screen_win_gles, SCREEN_PROPERTY_TRANSPARENCY, & transparency);

  If you do not, then transparency is random.

  And to add

  int alphamode = SCREEN_PRE_MULTIPLIED_ALPHA;

  RC = screen_set_window_property_iv (screen_win, SCREEN_PROPERTY_ALPHA_MODE, & alphamode);
  If {(rc)
  perror ("screen_set_window_property_iv (SCREEN_PROPERTY_ALPHA_MODE)");

• Loading image with a real transparent background?

  I am wanting to use an image on a background printing loadin.  All the .gif of loading files that I can find are not a real transparent background, but have a bit of color that looks really bad on a transparent bg.

  WebWorks provides native loading any image or does anyone have a solution to this?

  Oh, my mistake. But what is the problem when you use them in a background of template?

  What about CSS3 transformations to create an animation of loading/spinner? See this example or try searching "transformation CSS3 Animation": http://blog.crazyegg.com/2012/05/08/loading-spinners-css3-animation/

• Try a background image with a PNG with transparency matte / partial transparency

  Hello everyone.

  Here's the scenario;

  1. I have a PNG sequence rendered in a 3d program. The sequence has a landscape that is partially transparent and has no background image or color. In the animation, which is not the landscape is 100% transparent, while the landscape is partially transparent.
  2. I have a background that I want to put behind the PNG sequence but I don't want the background visible through the part of the landscape of the sequence, only the portion that is 100% transparent.

  I tried several different methods, but because the landscape is partially transparent, with a matte (alpha or alpha reverse) or blend (such as stencil alpha) mode does not give me the results I'm looking for.

  I'm looking for is a way of mast (or mask) the background image with only the part of the PNG that is 100% transparent. In this way, the background image are not displayed in the semi transparent landscape, but will be visible in the part that is 100% transparent.

  I would like to find a reasonable solution in After Effects, as opposed to the sequence of 3d objects rendered being invisible to the camera and the current background. The landscape scene itself took a considerable amount of time to make (120 hours) and I would like to avoid this kind of delay in my project.

  Thank you all in advance for your consideration.

  Maybe I said incorrectly: you cannot use the 3D app to generate a matte black and white simple - or mattes - to separate properly, then just composite in AE?

• How to superimpose a partially transparent image (created by the user RGB) on a grab image acquired (I16 in grayscale) session in a while loop?

  Hello

  I'm trying to superimpose a partially transparent Alpha, RGB image, which I have already created through manipulation of pixels on an image in grayscale I16.  I16 image is acquired grab and RGB is a file location.  So my problem is that when I try to add (IMAQ) images, IMAQ add.vi gives me an error of type incompatible image.  I understand that these are different types of images; but I need to find a work-a-round in order to get the information from color to grayscale during a frame grab session information.  This frame grab is quite awhile so it runs a bit slow which is correct loop.

  I already overlaid on an image I16 RGB.  However, the two images in this instance is called from a location file and not a capture session.  Now, I need a new vi which will overlap the file created on the images of the capture session.

  If any addition information is needed, please do not hesitate to ask.  This situation is a little difficult to explain.

  Thank you for your help,

• How can I import an image with transparent background .png in the Vision Assistant?

  Hello

  I am using the Vision Assistant of NOR. Here, I want to overlay one existing image with another. Therefore, I use the overlay Installer where can I import a .png image. If I do, I don't get

  the transparent background of the back of the image, even, I was saved with a transparent background. The image is displayed with an orange background.

  If I import the same image to any front panel for example, I see the picture on the right path with a transparent background. What I've done wrong? I have attached the image I want to use.

  Thank you

  Hello! Don't know how to do this in the Vision Assistant. Try to use the overlay (bitmap) or convert your image into mask. Effect of transparency not supported in the Vision. What you can do in LabVIEW is something like this:

  

  

• Saving binary Image with overlay?

  Hello

  I'm having some trouble in saving an image with overlay information. I use IMAQ find circles to measure the rays of the holes in a binary image. Hole data is then used with oval Overlay IMAQ, draw on ovals to highlight detected circles. Works very well and the image is displayed as expected in the output of the image on the screen, the palette has the binary value. (See the second image of 3, below)

  When I try and save the image in PNG I just get a blank image (black). If I use the overlay IMAQ merge tool, I just get the green circles on the black (see the last picture of 3 below). Is there something I'm missing with pallets/fusion? Any help much appreciated. Snapshot of the (messy) code attached.

  The problem is that the binary image is all zeros and ones.  A normal image goes up to 255, so the value 1 appears black.

  One solution is to multiply the binary image of 255, which makes the image black and white.

• How to make an image with a transparent background?

  I brought a picture of PS in Illustrator and I want to put in AE and use the puppet tool. However, when I bring what it has a white background, but I got everything as the object I'll puppet, so how can I do to?

  AE does not require an image will initially come out by Illy. Just make sure that your image has a transparent background or an alpha channel, if needed, and then save as a psd file. AE take the PSD in images, unless you need a compostion and folder for the psd, created in the project list. You should then be able to use the tool puppet on an image with a transparent background.

• Problem flashing with live viewing with IMAQ Image display

  Hello world

  I am writing a program for live imaging with camera Andor. I use some examples from Andor. The images are acquired in sequence and send in Image IMAQ and also graphical intensity display. There is minimal flicker issue in the graph of the intensity, but it is very bad flickering problem in display Image IMAQ. Maybe I wrong understand how to optimize vision tools. Does anyone know how to fix this? I enclose the code that I have tested. Thanks in advance.

  Best regards

  HI Han,.

  You should try a right-click on the screen and choosing "snapshot". Who help me? In addition, you have a while loop nested in a while loop and the Interior more than while loop I see you have a Subvi I have not (GetMostRecentImage16) according to what is in this VI, this could slow down things - especially since the chart and display have to wait for the most secret while loop at the end of execution before the update.

  You can remove the inside while loop?

• BlackBerry 5 - image with text and the background transparent resizing

  Hey,.

  My application consists of a series of images stacked on each other. Some are transparent, some are not. I use images high resolution and resize them based on the width of the screen of the blackberry that runs the application.

  I'm having some trouble resizing of images with text on a transparent background. The resulting image is not of all anti-aliasing. This is the code I use to do:

  function scaleBitmap(Bitmap bmp){
  
  int rgb[] = new int[imageWidth * imageHeight];
  bmp.getARGB(rgb, 0, imageWidth, 0, 0, imageWidth, imageHeight);
  int rgb2[] = rescaleArray(rgb, imageWidth, imageHeight, width, height);
  scaledBmp.setARGB(rgb2, 0, width, 0, 0, width, height);
  
  return scaledBmp;
  }
  

  And here are the results from a group of images resized in photoshop:

  

  Is it possible that I could improve my resize code to give better results?

  Thanks in advance!

  I found a solution and it is on these forums all the time!

• Newbie: background image with overlay problems

  I use a large background image with several circles superimposed over the image. When the image is resized to different browser screens, overlays remain unchanged, even if the changes of background image to fit the browser. As a result, overlays eventually his place with respect to the substantive parts and cover image, I don't want to not covered. Clearly, I'm a newbie with dreamweaver. Useful links?

  Mark

  This approach to layout does not work in flow layout (%).   APDivs are removed from the normal document flow and thus remain absolutely where you positioned them.

  Cards images do work either in fluid layouts.  As the picture re-sizes to fit the display window, the hotspot regions are not.

  When you create responsive Layouts, review your Mobile implementation objectives first.  Then tablets and desktop computers.  And above all, to keep things simple.

• GIF Image with a transparent background, has a background color when exporting to PDF

  Hi all

  I'm having a problem when you try to export a Microsoft Word or PowerPoint document which has GIF or PNG image with transparent background. When I save the file as a PDF file with the PDF option "ISO 19005-1 compliant (PDF/A)," the transparent background will have a colorful background after having been exported. This occurs when you try to export from Microsoft Powerpoint and Word 2007. Here is a screenshot of what the Gif and PNG images looks like after export.

  

  Does anyone have any ideas as to why what is happening?

  Thanks in advance!

  Mike

  PDF/A-1 does not support transparency, so you can't have both.
