Hi guys,
I wrote a Macro which enlarges my (very small) ROIs, which are stored in the ROI-Manager. For a different set of analysis, however, I have to reduce the the size of the ROIs. Somehow my code does not do what I want. Here the code with some made up ROIs.
When I increase the size, I can reduce the size afterwards (by enlarging with negative values), but I cannot reduce the size below the original ROI. Maybe because they are already very small? Any ideas how to do this?

This usually means that you did not actually select an annotation, so the selectedAnnots property of the current document not undefined. Make sure that your text box is actually selected before you run the script.
After changing the font size to 2 pt, I would like to reduce the line spacing of the text comment box to match the font size; but the minimum spacing I get with the tool button "reduce line spacing" reaches its minimum spacing at level that is roughly four times too much. Can anybody help me to do similar adjustment to the linespacing via javascript?
I couldnt get the advise below to work but I found that if you go to edit mode and insert text, you can change the font size there rather than messing around with javascript. Hope this helps anyone with the same problem in the future.
While in the purge GUI, I found that shape I need (which looks to be the whole equipment) claims to be 3570.306 KB. How is this possible? How do I retrieve this smaller, imbedded block? I've tried inserting just that block and is still comes out to be 40,000 KB.
I avoid using detailed design models in AutoCAD products, whether it's Plant3D, CADWorx, or AutoPLANT. There's far more detail there than is necessary to get the job done, which results in massive file sizes.
There is little to be done to reduce the file size when dealing with highly detailed imported models; instead, if you need to flatten or otherwise include the objects in generated drawings, spend 15-30 minutes with some boxes and cylinders to make a simplified generic (and very lightweight) version. If you are only using the model to reference nozzle locations, door swings, and other physical positions then use Navisworks Simulate or Manage to publish an NWD and reference that inside AutoCAD.
I want to enter an image into an online competition but the size needs to be less than 3 MB. Most of my images seem to be larger than this. How do I reduce the size of the image in either elements or iphoto? I get confused by the different ways of measuring the images. I just want to make the image less than 3 MB
Rename the file or accept any edit extension automatically added by elements; Then click the save button. You can adjust the quality slider between 1 to 12 to change the file size. A setting of 8 to 10 usually works well.
Thanks again Barbara, as usual you clarify things so well. I have managed to reduce the size to 1250x833 which gives me 705 KB but I have a real problem understanding the sizing of images. Does this sound like a reasonable size to send into an online photo competetion? Is there an easy way of understanding image sizes and what is suitable for what?
When an online site tells you to limit your photo to a size of "xx Mb or lower", they're doing that strictly for their own convenience -- they don't want to use up much storage space on their servers.
In general, you'll use 72 (or 96) pixels/inch as the resolution for images used for display on computer monitors, and 300 pixels/inch for images that will be printed on you home printer. After that, just adjust the Width and Height values so your image has the physical dimensions you need.
Go to "Save As" once you choose where to save and where you will be looking for it. The options will come up with a menu on "JPEG Options" with a slider bar. Slide it back and fourth and look to the right it will say what the file size is going to be. ie 3.1m or 5.1m and so on just slide it from 0-12 till you get as close to your file size as needed.
Thanks for your support. From where i need to do these changes in .config file or ls2085a_defconfig file. I did the changes in both the files and compiled successfully also kernel image size is reduced. Exactly in which file i need to do this changes.
I know while creating kernel itb the kernel image is compressed automatically on that time my 8MB kernel image is compressed to 4MB. Actually my requirement is to make the kernel image as below 5MB in uncompressed mode for that i excluded some unwanted configs in ls2085a_defconfig and .config file.
Because, now my kernel itb size is 40MB i need to make it as below 20MB for that i removed some packages in rootfs. But that one is not enough for my requirement for that i'm reducing the kernel image size.
If you are saving to JPEG after processing check your compression settings. File size can climb astonishingly high the closer you get to 100% quality without any noticeable difference in quality. Dropping it down to around 90% can cut file size quite a bit.
There are two settings that affect JPEG file size, resolution and compression. Experiment with both these settings until you get a balance between the two that works for you. All other things being equal, I usually compress my images more rather than resizing them more, however Flickr has size limits that may affect your choice here. Always remember to keep an original uncompressed and unresized copy of your photo as well!
When you save an image as a JPEG, the quality of the image is degraded in order to make the file smaller. You can control the filesize versus quality tradeoff in photoshop when selecting File and Save as... and choosing the JPEG format. You will be prompted for a compression setting. I never set this to more than 10 and neither should you, and settings down as low as 8 are generally satisfactory for me. When you set the JPEG quality, photoshop will estimate what the resulting filesize will be, enabling you to tailor this setting for the desired file size:
Resolution is the size of your image in pixels (or megapixels). My 550D saves images at 5184 x 3456 pixels, which is almost always way more than I need. For the purpose of posting to Flickr, unless you have a Pro account the practical maximum dimensions is 1024 pixels along the longest size, so there is little point in having a larger image than that. You can reduce filesize by resizing your image to a smaller size by going to the Image menu and select Image size:
What format are you saving the files in? If you're saving as TIFF or PSD, you could instead try saving to JPEG, which will be much smaller. If you're using JPEG and the files are still over 15 MB, those must be some HUGE images.
You have already gotten plenty of good answers. I do wish to add that there should be a separation between the size of your images, the size of your in working files and the size of the images you share:
Size of your images: That is the size of the output of your camera. Usually 5-10 MB for JPEGs and 10-24 MB for RAW files. This is the amount of data your camera has captured. It is highly recommended these never be overwritten.
Size of your working files: This the files you work in Photoshop (or similar traditional image editing applications). These files get very big because they contain layer information that allows you to modify some of the work you have already done. While these are larger than your originals, the increase size does not reflect more details.
In your case, what you want is to Export a version of your images for upload to Flickr. There are a number of tools to do that for you. Even Adobe's Lightroom will let you do that directly without you managing the intermediate files, it only asks what size you want to share them at. Picasa too can do this if you add the picasa2flickr plugin.
I suggest you resize the photos in Photoshop, go to the image menu, select "Image Size..." in the document size box enter something like 25%, save the image and you should be able to upload them onto Flickr without problems.
In addition to reducing the JPEG export quality, if you have a lot of detail in the image, and you are willing to sacrifice a little bit of sharpness for file size, you can add a little Gaussian Blur (less than 1px) for a dramatic effect on the final file size.
A quick tip: Photoshop files are .psd files which have extra Photoshop editing information. To publish or share with others in Flickr convert that file from psd format to jpg, png or gif as per requirement. Generally jpg is more suitable.
Now for reducing size:
1.) Check image size in Photoshop using image->image size and set it to nearly 800x600 or something that you think more appropriate for sharing. Remember the larger the dimension larger the file size.
2.) Save it with less jpg quality. Again larger the quality larger the size. It can be done using File->Save for web menu.
I will only give you a couple of the most used ones for many things besides converting from RAW, PSD or TIFF to JPEG and other interesting formats to be used for the Internet and other mediums: Adobe Photoshop Lightroom Classic, Capture One Pro, Affinity Photo and Adobe Photoshop.
this works well except there are many points (like 9000) and the red dots obscure some of the green dots (giving a wrong impression)
I would like to reduce the size of the markers (I tried size and size_max but in one case it gave me HUGE dots and in the other one the green dots appeared white (you could only see then green when zooming))
I've extracted contours from an image and now want to discard those that don't match a specified size requirement. But I'm new to Python and can't figure out how to do this efficiently. I can get a list of booleans that identify which contours should be retained, but how can I generate the new list of contours in a simple, single line?E.g., what's the right way to code the final line below? Thanks!
I am not sure if this would work for you but you can make use of contourArea method to get contour area and filter out some small contours on a basis of that. Here is the link.. Example code as below: 152ee80cbc
