This is a powerful little tool that helps converting single or batches of images to Android, iOS, Windows and CSS specific formats and density versions given the source scale factor or target width/height in dp. It has a graphical and command line interface and supports a wide array of image types for reading and conversion including PNG, JPEG, SVG, PSD and Android 9-patches. Using sophisticated scaling algorithms, it is designed to make conversion of images easy and fast while keeping the image quality high (comparable to PS).

            Why did my new python edited photo lose brightness?

            I am working on a photo editing project and I am curious about why did my new photo lose it's brightness. The program shoud get 2 photos out of the original one. One of them shoud contain only RED value and the other shoud contain BLUE and GREEN values. But when I put them back together the brightness is not the same as in original picture.

            blend2 = Image.blend(img, img2, 0.5)

            The third argument, 0.5, is the alpha level of each layer. Essentially, you are setting each layer to be 50% transparent. This effectively reduces the brightness. Instead, you should read in img1 and img2 and then set the red layer of the second to the red layer of the first.

            Python tkinter, resizing transparent image on canvas
            Asked 2021-Apr-02 at 12:39

            I am making an isometric game using python and the Tkinter library. I ran into a problem though when rendering my schematics to the screen. I can't seem to keep the transparent background even though the images (.png) are being stored as rgba in pil. When I save the images, as they are, just before being loaded; they still have a transparent background so it's something to do with the way I'm resizing the image. I have looked around and most answers to this that I have seen say to edit the pil plugin or aren't actually resizing the image. Is there a relatively simple way to resize an image and keep transparency that doesn't include messing around with the pil plugin??

            Ok, so I managed to find the issue. The problem was not with the resizing but with the label as @jasonharper had stated. The working way is very unclean and creates unused labels to store the variable to prevent movement to the python garbage. I have tried with an array/list however it doesn't seem to work, that code is below. I don't see many people having this issue in the future because it's so small but I'll put the working code below as well.

            Application/script for merging images, applying color, black & white filter in batch?
            Asked 2021-Mar-30 at 08:09

            I'm making achievements for my game, and I would like to make an automated process to save a lot of time instead of doing it manually. (I'm using Windows)

            The inputs of this process would be

            • one rectangular opaque background image (i.e. 200x200 PNG)

            • Color A, (i.e. in hex)

            • Color B, (i.e. in hex)

            • and multiple same sized, rectangular, transparent foreground images. (i.e. 200x200 PNG)

            And the process would do this for every foreground image:

            1. Start with the background image.

            2. Merge the foreground image with Color A filter applied, and also with an offset from the middle.

            3. Merge the foreground image with Color B filter applied, in the middle.

            4. Save the result in a file.

            5. Apply a black & white filter and save the result in a file.

            So the output would be for example multiple 200x200 PNG images, each of it having a colored and a black & white version

            I think there must be an application capable of this.

            But if not, is there a way to quickly do this in some programming/script language for example in Python?

            I just had to set the factor variable from ~1 to ~30 to change the contrast by giving these values to the function and the QSlider returned incorrect values.

            It is also possible to reverse the image colors by passing values from -1 to -30, to also change the contrast of the reversed image.

            so the right code will be like:

            Seems that you open the Image in Pillow and try to save the Pillow Image with OpenCV. OpenCV expect a numpy array. You should first convert your image before write in file with opencv.

            It seems unlikely you'd want to pass a PDF to OCR, since Tesseract et al prefer PNG or NetPBM PPM files, so you might as well split your big PDF into individual PNG (or other) files:
