Ssrs Image Rendering Pdf
2019-6-6 I'm having an issue with an image in an SSRS report. It's a.PNG, 300dpi, 185 x 58. When I run the report through VS, it renders fine. The image object in the report is set to render at original size, so that all is fine. The problem arises when I save as PDF. SSRS Report PDF image rendering issue. Ask Question Asked 3 months ago.

-->The Image rendering extension renders a paginated report to a bitmap or metafile. By default, the Image rendering extension produces a TIFF file of the report, which can be viewed in multiple pages. When the client receives the image, it can be displayed in an image viewer and printed. This topic provides Image renderer-specific information and describes exceptions to the rendering rules.
The Image rendering extension can generate files in any of the formats supported by GDI+: BMP, EMF, EMFPlus, GIF, JPEG, PNG, and TIFF. For TIFF format, the file name of the primary stream is ReportName.tif. For all other formats, which render as a single page per file, the file name is ReportName_Page.ext where. ext is the file extension for the chosen format. To produce a file in another Image-supported format, specify any of the above listed strings in the OutputFormatDeviceInfo setting.

Note
You can create and modify paginated report definition (.rdl) files in Report Builder and in Report Designer in SQL Server Data Tools. Each authoring environment provides different ways to create, open, and save reports and related items.
Supported Image Formats
The following table shows the file extension and MimeType for each Image renderer format.
| Type | Extension | MIMEType |
|---|---|---|
| BMP | bmp | image/bmp |
| GIF | gif | image/gif |
| JPEG | jpeg | image/jpeg |
| PNG | png | image/png |
| TIFF | tif | image/tiff |
| EMF | emf | image/emf |
| EMFPlus | emf | image/emf |
Rendering Multiple Pages
TIFF is the only format that supports multiple page documents in a single file. Other formats, such as JPG or PNG, output one page at a time and require a separate call to the rendering extension for each page.
Interactivity
Interactivity is not supported in any Image formats generated by this renderer. The following interactive elements are not rendered:
Hyperlinks
Show or Hide
Document Map Neighbors from hell game.
Drillthrough or clickthrough links
End user sort
Fixed headers
Bookmarks
Device Information Settings
You can change some default settings for this renderer by changing the device information settings. For more information, see Image Device Information Settings.

I have a report that renders images (jpg) that have been collected from various sources. This works fine within the report viewer, and when exporting via Excel.
However, when exporting to PDF, about 5% of the images are rendered incorrectly as can be seen below, with the original on the left, and what is rendered on the right;
I find that if I open up one of these images in mspaint, and just click save, on the next report-run the image is now rendered correctly.
Are there any rules as to what image properties/format are valid for SSRS to render the image correctly within a PDF? Essentially I'd like to somehow find these images that will render incorrectly before the report is run and fix them prior..

Because of the way the output looks I would say those JPEG images have CMYK colorspace but the SSRS assumes they use RGB colorspace and sets the wrong colorspace in PDF.
If you can post a JPEG image and a sample PDF I can give you more details.
I never ended up getting SSRS to display the the problem images as they were, however, determining before running the report which images would be included in the non-displayable set so they could be converted to a supported format (automatically) was also a solution.
In my case, all images were supplied via users uploading to a website, so I was able to identify and convert images as they arrived. For all existing images, I was able to run a script that identified the problem images and convert them.
Identifying problem images
From the thousands of images I had, I was able to determine that the images that wouldn't render correctly had the following properties:
- Image had CMYK colorspace or;
- Image had extended color profiles or;
- Both of the above
Converting an image
I was originally using the standard .NET GDI (System.Drawing) to manipulate images however the API is often prone to crashes (OutOfMemoryException) when dealing with images that have extra data. As such, I switched to using ImageMagick where for each of the identified images I:
- Stripped the color profiles and;
- Converted to RGB
Note that the conversion to RGB from CMYK without stripping the color profiles was not enough to get all images to render properly.
I ended up just doing those items on every image byte stream I received from users (without first identifying the problem) before saving an uploaded image to disk. After which, I never had the rendering problem again.
Stafford WilliamsStafford WilliamsI've had exactly the same problem with an image rendering correctly on screen but appearing like the one in the question when I exported the report to PDF. Here's how I solved it.
The Problem
The first clue was this article I came across on MSDN. It seems that regardless of the original image density, the PDF renderer in SSRS resizes all images to 96 DPI. If the original size of the image is larger than the size of the page (or container), then you will get this problem.
The Solution
The solution is to resize the source image such that it will fit on your page. The requires a little calculation depending on your page size and margin settings.
In my case, I'm using A4 paper size, which is 21cm by 29.7cm. However, my left margin is 1.5cm, and my right margin is 0.5cm, for a total inner width of 19cm. I allow an extra 0.5 cm as a margin of error, so I use an inner width of 18.5cm.
As noted before, the resolution generated by the PDF renderer is 96 DPI (dots per inch). For those of us not in the United States or Republic of Liberia, that's 37.79 DPC (dots per centimetre). So, to get our width:
Your result may be different depending on (1) the paper size you are using, and (2) the left and right margins.
As the page is higher than it is wide, we need only resize the width while keeping the image proportional. If you're using a paper size which is wider than it is tall, you'd use the length instead.
So now open the source image in Paint (or your image editor of choice), and proportionally resize the image to the desired width (or length) in pixels, save it, import it into your container, and size the image visually with respect to the container. It should look the same on screen, and now render correctly to PDF.

From SSRS 2008 How to get the best image quality possible?:
The image behavior you see in PDF is a result of some image conversions that the PDF renderer does, based on how the PDF specification requires that serialize images into PDF.
We know it's not ideal, and we classify the loss of image quality as a product issue. Therefore, it's difficult to really say what to do to get the best quality image.
Anecdotally, I have heard that customers have good results when the original image is a BMP
