52-52: Update assertion message to reflect.webpextension.The assertion message in
MediaHelperTest.javastill mentions "image's extension must be png", which is inconsistent with the expected extension ".webp". Please update the message to reflect the correct extension.

15-15: Logging configuration looks good.The addition of a logger for
com.sksamuel.scrimageat thewarnlevel is appropriate for monitoring significant issues related to the new Scrimage library.gradle/libs.versions.toml (1)
3-3: Dependency updates are appropriate.The addition of
scrimage-coreandscrimage-webpdependencies aligns with the transition to the Scrimage library for image processing tasks. The versioning is correctly specified.Also applies to: 22-23
build.gradle (1)
23-24: Dependency changes are appropriate.The removal of
libs.imgscalrand the addition oflibs.scrimage.coreandlibs.scrimage.webpreflect the intended transition to the Scrimage library for improved image processing.src/test/java/com/github/stickerifier/stickerify/media/MediaHelperTest.java (2)
116-116: Verify the change in expected PSD image height.The expected height has been adjusted from 384 to 383. Ensure this change reflects the correct expected output.
Verification successful
Change in expected PSD image height is due to library switch.
The adjustment of the expected PSD image height from 384 to 383 is a result of switching the image processing to the
scrimagelibrary, which handles image dimensions differently. This change is intentional and aligns with the updated processing logic.

22-23: New imports for Scrimage are appropriate.The addition of
ImmutableImageandWebpWriterimports is necessary for handling WebP images with Scrimage.
182-191: Use ofImmutableImageis appropriate.The change to return
ImmutableImagealigns with the use of Scrimage. Ensure compatibility across the codebase.Verification successful
Compatibility with
ImmutableImageconfirmed.The usage of
ImmutableImageis consistent across multiple methods inMediaHelper.java, indicating that the codebase is updated to handleImmutableImageobjects appropriately.

232-233: Verify image compliance logic.Ensure that the compliance checks for WebP and PNG images accurately reflect the requirements.
Verification successful
Image compliance logic is correctly implemented.
The
isImageCompliantmethod accurately checks for PNG and WebP formats and ensures size compliance using theisSizeCompliantmethod, which verifies dimensions against aMAX_SIZEboundary. The logic is consistent with expected requirements for these image formats.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify the compliance logic for WebP and PNG images. # Test: Search for `isImageCompliant` implementation details to ensure accuracy. rg --type java 'isImageCompliant'Length of output: 325

268-285: Verify WebP file creation logic.Ensure that the logic for creating WebP files is correct and meets the requirements.
Verification successful
WebP file creation logic is correct and meets requirements.
The
createWebpFilemethod correctly implements the logic for creating a WebP file with maximum lossless compression and checks the file size against the required threshold. The use ofcreateTempFile,WebpWriter.MAX_LOSSLESS_COMPRESSION, andisFileSizeLowerThanensures that the process is handled appropriately.
createTempFile: Creates a temporary file with the specified type.WebpWriter.MAX_LOSSLESS_COMPRESSION: Utilised for maximum compression.isFileSizeLowerThan: Validates file size compliance.Scripts executed

214-221: Verify WebP conversion logic.Ensure that the logic for converting images to WebP format is correct and meets the requirements.
Verification successful
WebP conversion logic is correctly implemented.
The
convertToWebpmethod, along withcreateWebpFileandresizeImage, correctly handles image conversion to WebP format. The process ensures compliance with size requirements and handles exceptions appropriately. No issues found with the logic.
convertToWebp: Checks compliance and decides on conversion.createWebpFile: Converts and checks file size.resizeImage: Resizes images to meet maximum size constraints.Scripts executed

convertToPngtoconvertToWebpreflects the new image format. Ensure all related logic is updated for WebP.Verification successful
Transition to WebP conversion is correctly implemented.
The
convertToWebpmethod includes logic to handle image compliance and file size checks before converting to WebP, ensuring proper functionality. No further issues were found.

134-134: Consider the implications of disabling content type detection.The addition of
.disableContentTypeDetection(true)in theSendDocumentchain modifies how the document's content type is detected by Telegram. This can be useful for sending non-standard file types or ensuring consistent behaviour across different Telegram clients. However, be aware that it might affect how the document is processed or displayed on the client side. Ensure this aligns with the intended use case.
