We tried to test the performance of two images on site’e homepage. We tested one image then the other one. Now the issue is the image which is having large size, better quality as well as large dimensions is giving us better speed results as compared to the image having small size and less quality even though it should have been opposite to it but help me figure out why is that. The image is the first image on site’s homepage.
Speed results: https://pagespeed.web.dev/report?url=https%3A%2F%2Fhijrahpress.com%2F
Image that gives better results is named with large(having large size, dimensions and high quality) and other as small.

Large image currently used on homepage.
The suggestion are to convert the png image to webp.
It should be sized to fit your page. The image size on your webpage is 600 x 900.
I converted for you. This is much improved.
arabicgrammar.webp 600 x 900px
When I save a image from a picturebox using Picturebox1.Image.Save, the saved image size is much larger than the original image size (for example, from 1.5 MB to 15 MB). What can I do for the image will be saved in the same size of the original image?
Thank you in advance.
You probably load a JPEG or PNG image into the Picturebox, which are compressed file formats. However Picturebox1.Image.Save saves it as a bitmap, if you do not specify the type. Bitmaps are uncompressed and therefore quite large. You can change this by using
Picturebox1.Image.Save(Outputfilename, Drawing.Imaging.Imageformats.Png)
This saves the image in the PNG-Format, which is much smaller.
I have a search icon at 2kb. I open in Photoshop, reduce it's dimensions to half, and the size comes out as 4kb.
Any idea what I can do to reduce the size when saving and reducing the dimensions? Not sure what's causing this.
Thank you!
When object is a vector it cost low space in the photoshopfile.
you can use png8 instead of png24 to save a lot of bytes
I have tried the following methods,
normal image upload.
encoding and decoding.
these two methods are taking long time to upload the image.
Any suggestion?
There are some simple ways:
Reduce the size of the image. From 1000x1000 to 500x500
Reduce the bpp of the image. For example instead of RGBA representation (32 bits per pixel) use RGB_565 (16bits per pixel) or even gray level image (8bits)
Reduce the quality of the image. Save it as .jpg. This will make the image much smaller. You can play with the quality parameter of jpeg. 100% means very high quality and large files, 1% means extremely tiny images (~40 times smaller) but all the details will be lost.
Save the image in Jpeg200 format. It reduces the size even further. Not every browser supports this format, so you might need to convert it to regular jpeg.
Use pyramids of images. For example. You have 1000x1000 image. Reduce its size by 2 to get 500x500, reduce again and again. Now you got 4 images 1000x1000, 500x500, 250x250, 125x125. You upload the 4 of them. Starting from the smallest to the largest. The smallest image will be uploaded very quick and you will be able to display it (though it is in lower resolution). Next when a better image arrives you update the display and resolution enhances. The effect would be that the basic image is loaded extremely fast and over time the resolution is enhanced. The transfer time of the 4 images will take only 30% more time than the original but the first one will arrive 64 times faster than the original
These are the basic solutions. If they are not what you needed please refine the question
I have an app that creates a large bitmap and later the user can add some labels. Everything works great as long as the base bitmap is the default 96x96 resolution. If I bump it up to 300 for instance, then the text applied with Graphics.DrawString is much too large - a petite size 8 or 10 font displays like it is 20.
On the one hand, it makes sense given the resolution increase, but on the other, you'd think the Fonts would scale. MeasureString returns a larger size when measured on a 300 vs 96 dpi bitmap, which wasn't really what I expected.
I've tried tricking it by creating a small bitmap of the appropriate size, printing to it, then pasting that to the master image. But when pasted to the high res it enlarges the pasted image.
The only other thing I can think of is to create a high res temp bitmap, print to it, then shrink it before pasting to the main image. That seems like a long way to go. Is there a compositing or overlay type setting that allows this? Are font sizes only true for a 96 dpi canvas?
Thanks for any hints/advice!
The size of a font is expressed in inches. One point is 1/72 inch. So if you draw into a bitmap that has 300 dots-per-inch then your font is going to use a lot more dots for the requested number of inches. So when you display it on a 300 dpi display then you'll get the size in inches back that you asked for.
Problem is, you are not displaying it a 300 dpi device, you are displaying it on a 96 dpi device. So it looks much bigger.
Clearly you don't really want a 300 dpi bitmap. Or you want to draw it three times smaller. Take your pick.
If you want a consistent size in pixels, specify UnitPixel when creating your Font object.
