Is there a way to get the actual image size (width/height) of a cropped image ("Image manipulation" > [Open Editor]) in a fluid template?
All I can come up with is {image.properties} and width and height. But these are the dimensions of the original resource, not the cropped one. And there is of course an attribute crop which holds all the crop info:
{"default":{"cropArea":{"height":0.6431784107946027,"width":0.608,"x":0.037,"y":0.15592203898050974},"selectedRatio":"NaN","focusArea":null}}
But do I really have to find a way to parse this in fluid (if that's even possible)? Isn't there an official way to calculate the actual dimension of a generated image?
My use case is an image gallery component for which I need to explicitly state the image dimensions.
In TYPO3 Fluid, You can crop image like below. See here
<f:image src="{image ogject}" alt="Landscape" width="100c" height="100c" />
You could use the VHS Media / SizeViewHelper https://fluidtypo3.org/viewhelpers/vhs/master/Media/SizeViewHelper.html
<f:format.bytes><v:media.size path="{f:uri.image(image: mediaElement, width: 600) -> v:format.trim(characters: '/')}" /></f:format.bytes>

I have TYPO3 10 and want to render the images in specific dimensions. I have a content element with only images, and these pictures are rendered with the dimension 495px x 331px. How can I change that? I've uploaded a much bigger original picture. The preview images are always in these dimensions. If I click on the image to enlarge it, it shows a much bigger picture.
The content element is a pictures only element with two columns.
When I set one column, the preview pictures are bigger. How is TYPO3 calculating the dimensions of the pictures?
I assume you want to know how to style the default content type "image".
This content type usually renders a gallery view (grid) of images.
First of all you have these options by default:
Selecting "Number of columns: 1" would make the image use a bigger space.
If you want to directly influence the HTML output, here are some pointers:
The default rendering engine of TYPO3 is fluid_styled_content.
Here is a guide how to override templates for a specific content type:
https://docs.typo3.org/c/typo3/cms-fluid-styled-content/10.4/en-us/Configuration/OverridingFluidTemplates/Index.html
That specific content type uses a GalleryProcessor:
https://github.com/TYPO3/TYPO3.CMS/blob/10.4/typo3/sysext/fluid_styled_content/Configuration/TypoScript/ContentElement/Image.typoscript
It renders this template:
https://github.com/TYPO3/TYPO3.CMS/blob/10.4/typo3/sysext/fluid_styled_content/Resources/Private/Templates/Image.html
... which uses some partials to render the media.
Media/Gallery sets up the layout for the image grid:
https://github.com/TYPO3/TYPO3.CMS/blob/10.4/typo3/sysext/fluid_styled_content/Resources/Private/Partials/Media/Gallery.html
Media/Rendering/Image finally renders the image. The value of dimension has been calculated by the GalleryProcessor:
https://github.com/TYPO3/TYPO3.CMS/blob/10.4/typo3/sysext/fluid_styled_content/Resources/Private/Partials/Media/Rendering/Image.html
AEM offers a plugin to create image maps for its internal inplace editor. After configuration the given values are stored into follow forrmat:
[rect(89,92,356,368)"/content/sites/we-retail/us"|"_blank"|"fdfdfdfdf"|(0.2,0.2004,0.8,0.8017)]
The first paratheses are defines the coordinates of choosen shape.
The content within the first quotaion signs defines the target site, within the second how to open it the browser. In the third pair of quotations sign contains an alternative Text for non images display.
What I don't know are the values in second paratheses. Does someone know for what these values stands for?
From the WCM core components Image model, they are called relative coordinates.
They are not standard HTML attributes and are instead populated as data attributes of the area tag within the image component.
See code below:
<area shape="${area.shape}" coords="${area.coordinates}" href="${area.href}"
target="${area.target}" alt="${area.alt}" data-cmp-hook-image="area"
data-cmp-relcoords="${area.relativeCoordinates}">
Since the map coordinates are fixed coordinates and do not change when the image scales in or not based on screen sizes, the image component’s JavaScript uses this relative coordinates data to adjust the coordinates of the map area whenever the image size is adjusted. This is handled by the resizeAreas() function within the component’s clientlib.
TYPO3 crops the media files which were added as text & media. How can I disable this? I want that it uses the original file.
It always takes this:
fileadmin/_processed_/c/a/csm_herren2_b3373d24a3.png
Change the fluid template and remove the width and height attributes of the
Or maybe easier change the typoscript constant that define the max size to a higher value styles.content.textmedia.maxW = 600 and styles.content.textmedia.maxWInText = 300.
Consider this scenario. I save a plotted curve using the save option in OMEdit Plotting Window. I want to use this image in the Documentation of the same model as a reference for others. But the issue with this is the images that are saved using this feature are very big and take up a lot of space(i.e. width and height) in the Documentation window.
I tried using the HTML code width = "xx" height = "yy". But this did not work.
Is there any way I can resize the images using HTML code in the OpenModelica Documentation?
Just for information. The size of the exported plot image depends on the size of the plot window. The plot window is a MDI container so you can resize the plot window and then can export a smaller image.
The following code works fine for me (uses the same Documentation annotation as suggested by Martin),
model documentation
annotation(Documentation(info = "<html>
<img width=\"200\" src=\"modelica://documentation/modeling.png\" />
<br />
<img width=\"100\" src=\"modelica://documentation/modeling.png\" />
</html>"));
end documentation;
Here is the sample screenshot,
I have a report designed with iReport 1.3.0. This report includes several images, which are loaded dynamically. Then I use JasperRunManager.runReportToPdfFile to create the PDF. Everything in the PDF looks fine except for the images, which appear scaled.
Can anyone tell me what am I doing wrong?
Thanks.
About Images
If you save the report as HTML, you will notice that the logo appears correctly.
Image files such as PNG are raster images: stored as individual pixels.
Whereas PDF files are primarily vectorized: the elements inside are stored as descriptions of how to draw them. This allows PDFs to scale and be legible at any size.
Using a raster image in a vector format will likely result in a pixelated effect.
Possible Solutions
You have a few options to make the images match the quality of the text, in order of ease:
Create a version of the logo at 1200 dpi, scaled 400% larger.
Create an SVG version of the logo.
Convert the image to a vector format.
Scale image 300% and change resolution to 288 dpi.
1200 DPI Version
The image will look sharp until around 400% zoom.
SVG Version
The image will look sharp at every resolution. Replace the normal <image...> XML with the following code (be sure to adjust the width and height accordingly):
<image hAlign="Center" vAlign="Middle">
<reportElement x="0" y="0" width="179" height="66"/>
<imageExpression class="net.sf.jasperreports.engine.JRRenderable"><![CDATA[net.sf.jasperreports.renderers.BatikRenderer.getInstance(new java.io.File("/path/to/logo.svg"))]]></imageExpression>
</image>
Convert GIF to SVG
To convert a GIF to SVG, first try a quick web-based tool, such as: http://vectormagic.com
Once converted to SVG, you will have to use the code listed above to display the logo.
Resolution and Scale
See:
https://stackoverflow.com/a/39320863/59087
http://www.webdevelopersjournal.com/columns/ajs_resolution.html
As of version 4.0.1 raster image resolution should be preserved and you can also improve the resolution of charts when using other export options (xls, rtf, html etc). The default is only a very low 72 dpi.
In iReport Options > JasperReport Properties edit
net.sf.jasperreports.image.dpi 300
http://jasperforge.org/projects/jasperreports/tracker/view.php?id=3411
In newer versions you need to configure the net.sf.jasperreports.image.dpi property globally by defining a jasperreports.properties file inside WEB-INF/classes/ folder with this line in it:
net.sf.jasperreports.image.dpi=300
A server restart is also needed.
