Convert an file image into a PICT resource in a .r file

Hi,
I have a small image in a file (already converted to .pict format) and I would like to add this image as a PICT resource into an existing .r file in an xcode project. Is there a utility somewhere that will convert the image to the ascii hex format that's required for the .r file?
Thanks,
tom

Thanks, but derez will not work in my case. The image in question is not in a resource fork. The image is in the data fork of a .pict file (originally converted from a .jpg file).
The reason I need this is because I already have a complete application which makes a call to GetPicture() to obtain an image that is already located in a .r file as a resource 'PICT' { ... } . All I want to do is to replace existing image in the .r file with my new one. That's why I would like to convert my image into the ascii hex format required.
I figure it must be something simple, but I haven't been able to find a tool to do this.
Thanks,
tom

How to save an image as a PICT resource file?

Can someone tell me how to save an image as a PICT resource file? I'd like to make ikons in Photoshop and save them in this format, but I 'm not finding any leads. Thanks!

If you have Resorcerer from "ancient times" it of course can handle resource forks since that's was it's goal in life.
There are lots of icon creation apps these days. Do a search for "icon" on macupdate.com to see what's available. For example that search finds:

HELP - CONVERTING A JPEG IMAGE INTO A LINE DRAWING

PLEEEASE HELP ME!!!
sorry to be thick - im only a beginner --- is there any way to covert a jpeg image into like a line drawing where there is a block colour background and solid lines that make up the picture like you sometimes get in brochures - somthing different to just the effects that are availible in the filter gallery...
thanks
LUK

As far as I recall there's no magic/easy "convert to vector drawing" functionality in Photoshop, though there are some things you can do to help smooth rough edges (e.g., Filter - Noise - Median). There are also some things you can do, if you want to get fancy, based on converting selections to paths, but that can get kind of involved and likely requires manual path editing afterward.
I have heard there are some pretty decent vector conversion functions in other Adobe apps... Adobe Illustrator, perhaps? Someone who uses Illustrator may want to chime in here; I don't have that package.

How to convert 24bits png image into 8 bits image

Hi,
I have gone through some of threads in this forum on changing color bits. But, I still can find right way to change my image (24bits) into different color bits(8 bits). The reason i want to change the color bits because I am getting a GIF image from map server, convert it into PNG format then rescale then into size of mobile phone screen.The PNG image is really has large data length , so the it took a while to load the whole image on screen.
Note : The following code is taken from few threads in this forum and i have modified it to suit my application.
I have no idea about Java2d...any help really appreciated...Thanks in advance!!!
My code is as follow:-
public File Scale(int width, int height, BufferedImage ImgSrc)
     try
               //BufferedImage bi = ImageIO.read(ImgSrc);
               //int w = bi.getWidth(), h = bi.getHeight();
     //Image oldRescale = bi.getScaledInstance(i, j, Image.SCALE_SMOOTH);
     BufferedImage Rescale = rescale(ImgSrc, width, height);
               //ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
               //ColorConvertOp op = new ColorConvertOp(cs, null);
               //Rescale = op.filter(Rescale, null);
     File outfile = new File("map.png");
               ImageIO.write(Rescale, "png", outfile);
               BufferedImage fromFile = ImageIO.read(outfile);
               ColorModel cm = fromFile.getColorModel();
               System.out.println(cm.getClass() + ", bits/pixel=" + cm.getPixelSize());
          catch(Exception e)
               e.printStackTrace();
          return new File("map.png");
     public static GraphicsConfiguration getDefaultConfiguration()
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gd = ge.getDefaultScreenDevice();
return gd.getDefaultConfiguration();
     public static BufferedImage copyRescaled(BufferedImage tgt, BufferedImage src)
          Graphics2D g2 = tgt.createGraphics();
int w=tgt.getWidth(), h=tgt.getHeight();

     g2.drawImage(src, 0, 0, w, h, null);
     g2.dispose();
return tgt;
public static Graphics2D hintForBestQuality(Graphics2D g2)
g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
          RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g2.setRenderingHint(RenderingHints.KEY_RENDERING,
          RenderingHints.VALUE_RENDER_QUALITY);
return g2;
     public static BufferedImage rescale(BufferedImage src, int w, int h)
int transparency = src.getColorModel().getTransparency();
GraphicsConfiguration gc = getDefaultConfiguration();
BufferedImage tgt = gc.createCompatibleImage(w, h, transparency);
return copyRescaled(tgt, src);

First, we need to be clear about what you're trying to do -- is it rescale an
image or insure that the image is saved with a 8bit pixel depth? Or both? You are also
using GraphicsConfiguration's createCompatibleImage, which is excellent if you are going
to display the image immediately because it might be hardware accelerated
or compatible with hardware format, but you mentioned mobile phone screens, so
there is no advantage to using GraphicsConfiguration in that case, and if fact, it's
probably changing your ColorModel when you're not looking.

How can I convert a bitmap image into an array in LabVIEW 6.0.2, then to a spreadsheet for further analysis without NI-IMAQ or Vision?

I do not have NI-IMAQ or NI Vision.
I acquired the image using a picolo board then just saved it as a bitmap file.

You want to convert it to an array of what? Of numbers? Of LabVIEW colors?
The "Read BMP File.vi" VI outputs a 1-D array of the pixels, but I suspect it is not exactly in the format that you need. I am NOT sure, but I think that each group of 3 elements of that 1-D array (which is inside the cluster "image data" that the VI outputs) represents the red, green and blue levels of a single pixel (but it may be hue, saturation and lum.). Also, since it is a 1-D array, you would have to divide it by the width (which is also included in the "image data" cluster) to get some sort of 2-D array of data.
You can find the "Read BMP File.vi" VI in the functions palete> "Graphics & sound">"Graphics Formats".

Is there any way of converting a jpeg image into a vector in Fireworks? Deity Babbage, where be thee?

I am hoping for a quick way of converting images (jpeg etc) into a vector.
Is this possible?
Thanks
Eddie

Try this:
http://vectormagic.com/home
It won't work with really complex images or photos, but if you have something like a logo, it can work well. You'll need to edit the vectors it generates to smooth out some bumps and incorrect nodes, but editing a vector is much easier than drawing the whole thing from scratch.
Hope this helps!

How to convert an pdf image into a jpeg

I just purchased export pdf and I'm trying to convert from pdf to word or ppt. The pdf is an image / logo that I want to make a jpeg. I used the export utility and keep getting random characters and not an image. I'm guessing it's looking for text. Do I have the right utility?

I don't see converting to Word as the right way to go if you want a picture.
Instead, view in Adobe Reader as large as possible, take a screen shot, paste in PAINT.

How can i convert an image into gif file as jpeg by using com.sun.image.*

please help me to convert an image into gif format. i have used sun's impl com.sun.image.code.jpeg package to convert a buffered image into a jpeg file. is there any implementatioln available from sun to handle gif files.

Many. Try for instance google with 'java image encoders'. Go to the URL http://www.google.com/search?q=java+image+encoders and be amazed of the wonders of modern web search tools.

Converting U8 image into RGB

I have a pixelink camera that when I run through the IMAQdx vi's, it produces a BW image. When I view the image, I can select from the palette bar when I right click on the image out display and select rainbow, temperature, etc....but I can't save these colored images. I'm guessing that the image out viewer converts the U8 image into a RGB image for display. I would expect that there would of been a VI (or maybe there is and I haven't seen it) that would do this task and allow you to save the image as a RGB. Is there a VI to do this?
Thanks,
guilio_2008

Do you have the NI Vision Development Module? If so, this sloppy little bit of code will let you change an image palette on the fly, then save out a copy of the color image you see. You can also choose a user defined palette and create your own palette with the color ramp next to the window.

How to use a grayscale color model in converting a colored image

how to convert a colored image into grayscale using :
ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
int bits[] = new int[] {8};
ColorModel cm = new ComponentColorModel(cs, bits, false, false,
Transparency.OPAQUE,
DataBuffer.TYPE_BYTE);
please only this method , i don't need the "bandcombine" method cause i need to know that i have exact 256 grayscale colors, thanx in advance.

I went into mail preferences in the first place. I found the fonts and colors and picked the color I want but it doesn;t seem to be sticking?

Convert scanned handwriting (raster) into digital ink (vector)

Do any of the Adobe products (or any other software) convert raster based images into vector... specifically I am wanting to convert pages of scanned handwriting into digital ink (NOT editable text). I will then use a suitable tablet and stylus to add/remove handwritten words to the digital ink text. I have been using Onenote and a Surface Pro and stylus to generate handwritten text but have a number of existing manually handwritten pages that I would like to convert to digital ink and then modify in Onenote or some other suitable program.

illustrator, indesign, flash, shape and probably several other adobe products can convert rasters to vectors.

How to convert jpeg images into video file of any ext using JMF

I want to convert the Jpeg files into video clip with the help of JMF
any one can help me?
Plz reply me at [email protected]
or [email protected]

I'm not sure of his/her reasoning behind this, but I have yet to find a way to record video with mmapi on j2me. So with that restriction, I can see how one could make it so that it just records a lot of jpegs, and then makes it a movie.
I would be interested finding a workaround for this too. Either if someone would explain how to record video with mmapi or how to make recorded images into a video. Thanks!

How to Convert Bitmap Images into WPF XAML files

Hi,

http://stackoverflow.com/questions/129972/convert-an-image-to-xaml
http://stackoverflow.com/questions/15082716/can-we-convert-an-image-to-xaml-using-expression-blend
this is not a trivial task [and maybe beyond the scope of this forum]. If you had some vector image like svg images there might be a control out to use, but with raster images, I dont know of any control or code to use; I *think*, you will have to vectorize
the image content yourself, which isn't that easy...
So, is Background and Foreground easily distinguishable? Do shapes overlap? ...
If there are only some shapes in the image and BG and FG can be separated easily then you could "scan" the image by some chaincode like operation to get the contours/contour vectors and then decide what to do. If there are patterns in BG or FG
things will become more difficult, you then will have to perform more math-to-image operations and a vector-representation while reading/scanning the image might not be enough (keywords are computer vision, pattern recognition [with multi-linear-forms] etc).
Maybe an existing computer vision [-able] component loke opencv can help a lot...
Edit: I just did a google lookup and found eg this:
http://www.cs.ucla.edu/~dt/theses/vasilescu-thesis.pdf
I havent read it so far, so I cannot say, if its what you need, but title and a quick view into looks promising/interesting.
